In visible light, the Milky Way's center is hidden by clouds of obscuring dust and gas. But in this stunning vista, the Spitzer Space Telescope's infrared cameras, penetrate much of the dust revealing the stars of the crowded galactic center region. A mosaic of many smaller snapshots, the detailed, false-color image shows older, cool stars in bluish hues. Red and brown glowing dust clouds are associated with young, hot stars in stellar nurseries. The very center of the Milky Way has recently been found capable of forming newborn stars. The galactic center lies some 26,700 light-years away, toward the constellation Sagittarius. At that distance, this picture spans about 900 light-years.
These three bright nebulae are often featured on telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. In fact, 18th century cosmic tourist Charles Messier cataloged two of them; M8, the large nebula below and right of center, and colorful M20 near the top of the frame. The third emission region includes NGC 6559, left of M8 and separated from the larger nebula by a dark dust lane. All three are stellar nurseries about five thousand light-years or so distant. Over a hundred light-years across the expansive M8 is also known as the Lagoon Nebula. M20's popular moniker is the Trifid. Glowing hydrogen gas creates the dominant red color of the emission nebulae. But for striking contrast, blue hues in the Trifid are due to dust reflected starlight. The broad interstellarscape spans almost 4 degrees or 8 full moons on the sky.
Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.
This work is based on Chandra observations of the remains of a supernova called Cassiopeia A, located in our galaxy about 11,000 light-years from Earth. This is one of the youngest known supernova remnants, with an age of about 350 years.
This image shows the region of sky in the southern constellation of Puppis surrounding the red giant star L2 Puppis. This rich area of the Milky Way includes glowing red clouds of hydrogen as well as some dusty clouds known as cometary globules.
This huge elliptical galaxy NGC 5128 (also known as Centaurus A) is the closest such galaxy to the Earth, at a distance of about 12 million light-years. Observations with ESO’s Very Large Telescope in Chile have discovered a new class of “dark” globular star clusters around this galaxy.
Rather than showing spectacular objects, some of the most surprising images of the Universe instead focus on emptiness. This new image from the 2.2-metre MPG/ESO telescope shows dark tentacles swirling outwards from a dark, blank spot of space in the center of the frame, particularly conspicuous against the dense peppering of bright gold and red stars across the rest of the image.
This region is not a hole in the cosmos, or an empty patch of sky. The dark lanes are actually made up of thick, opaque dust lying between us and the packed star field behind it. This obscuring dust forms part of a dark molecular cloud, cold and dense areas where large quantities of dust and molecular gas mingle and block the visible light emitted by more distant stars.
This image is a color composite of the Eagle Nebula (M 16) made from exposures from the Digitized Sky Survey 2 (DSS2). The field of view is approximately 3.8 x 3.3 degrees.
This image shows the sky around the young star MWC 480 in the constellation of Taurus (The Bull). This picture was assembled from images forming part of the Digitized Sky Survey 2.
A simulation but still cool to watch as it encompasses the latest science.
What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but create energetic neutrinos -- one of which may have been seen recently on Earth.
This zoom video starts with a wide view of the Milky Way and ends with a close-up look at a dazzling region of newly-forming stars in the HII region LHA 120-N 180B — also known as N180. This glowing region of newborn stars in the Large Magellanic Cloud (LMC) was captured by the Multi Unit Spectroscopic Explorer instrument on ESO’s Very Large Telescope. The relatively small amount of dust in the LMC and MUSE’s acute vision allowed intricate details of the region to be picked out in visible light.

NASA’s Ingenuity Helicopter Failed to Takeoff for Fourth Flight on Mars
An issue identified earlier this month showed a 15% chance for each time the helicopter attempts to fly that it would encounter a watchdog timer expiration and not transition to flight mode. Today’s delay is in line with that expectation and does not prevent future flights.

I was bummed about the 4th flight, but it will be fine and should fly again many times. SpaceX stood down from testing SN15 today, probably will go Monday, was really looking forward to that.
SpaceX Crew-1 NASA astronauts headed home after six-month stay on International Space Station
A quartet of astronauts in a SpaceX Dragon spacecraft have undocked from the International Space Station and are on their way home after a six-month stay aboard the orbiting laboratory.- The Dragon capsule is expected to splash down in the Gulf of Mexico at 2:57 a.m. Sunday. If conditions in the primary recovery zone are not good, the capsule could land in the Atlantic Ocean.
- It’s the first time a U.S. space capsule has landed under the cover of darkness since 1968.
- The astronauts aboard the capsule, Americans Michael Hopkins, Victor Glover and Shannon Walker and Soichi Noguchi of Japan, set the record for the most days in space by a crew launched on a United States spacecraft, surpassing the milestone of 84 days that was set by the Skylab 4 crew in 1974.
- Once the crew splashes down, speed boats will rush to the capsule to secure it while the recovery ship gets in place. It will then hoist the spacecraft to its deck, and the astronauts will disembark.

My 1,000th post!
This spectacular view from the NASA/ESA Hubble Space Telescope shows the rich galaxy cluster Abell 1689. The huge concentration of mass bends light coming from more distant objects and can increase their total apparent brightness and make them visible. One such object, A1689-zD1, appears in this picture — although it is still so faint that it is barely seen.
New observations with ALMA and ESO’s VLT have revealed that A1689-zD1 is a dusty galaxy seen when the Universe was just 700 million years old.
This image of the unusual planetary nebula was obtained using ESO’s Very Large Telescope at the Paranal Observatory in Chile. In the heart of this colorful nebula lies a unique object consisting of two white dwarf stars, each with a mass a little less than that of the Sun. These stars are expected to slowly draw closer to each other and merge in around 700 million years. This event will create a dazzling supernova of Type Ia and destroy both stars.
This extract from the VISTA VVV survey of the central parts of the Milky Way shows the famous Trifid Nebula at the bottom. It appears as faint and ghostly at these infrared wavelengths when compared to the familiar view at visible wavelengths. This transparency has brought its own benefits — many previously hidden background objects can now be seen clearly. Among these are two newly discovered Cepheid variable stars, the first ever spotted on the far side of the galaxy near its central plane.
Zoom in of the above.
Trifid Nebula in visible light.
This wide-field image shows a rich region of the sky in the constellation of Puppis. At the center lies the strange cometary globule CG4. Other interesting objects are also seen, including several much more distant spiral galaxies. This color view was produced from images forming part of the Digitized Sky Survey 2.
NGC 3199 lies about 12,000 light-years away, a glowing cosmic cloud in the nautical southern constellation of Carina. The nebula is about 75 light-years across in this narrowband, false-color view. Though the deep image reveals a more or less complete bubble shape, it does look very lopsided with a much brighter edge along the top. Near the center is a Wolf-Rayet star, a massive, hot, short-lived star that generates an intense stellar wind. In fact, Wolf-Rayet stars are known to create nebulae with interesting shapes as their powerful winds sweep up surrounding interstellar material. In this case, the bright edge was thought to indicate a bow shock produced as the star plowed through a uniform medium, like a boat through water. But measurements have shown the star is not really moving directly toward the bright edge. So a more likely explanation is that the material surrounding the star is not uniform, but clumped and denser near the bright edge of windblown NGC 3199.

Several pages ago, I posted a pic taken from the sky crane of it lowering Perseverance. After seeing the video on 60 minutes tonight of the landing, I said I gotta post that video, so cool. And I forgot to mention in my post above, the first image, look at all the gravitational lensing going on (all the streaks)...so many galaxies in that image.

Clusters of stars can be near or far, young or old, diffuse or compact. The featured image shows two quite contrasting open star clusters in the same field. M35, on the lower left, is relatively nearby at 2800 light years distant, relatively young at 150 million years old, and relatively diffuse, with about 2500 stars spread out over a volume 30 light years across. Bright blue stars frequently distinguish younger open clusters like M35. Contrastingly, NGC 2158, on the upper right, is four times more distant than M35, over 10 times older, and much more compact. NGC 2158's bright blue stars have self-destructed, leaving cluster light to be dominated by older and yellower stars. In general, open star clusters are found in the plane of our Milky Way Galaxy, and contain anywhere from 100 to 10,000 stars -- all of which formed at nearly the same time. Both open clusters M35 and NGC 2158 can be found together with a small telescope toward the constellation of the Twins (Gemini).
This is spectacular...The dark Horsehead Nebula and the glowing Orion Nebula are contrasting cosmic vistas. Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, they appear in opposite corners of the above stunning mosaic. The familiar Horsehead nebula appears as a dark cloud, a small silhouette notched against the long red glow at the lower left. Alnitak is the easternmost star in Orion's belt and is seen as the brightest star to the left of the Horsehead. Below Alnitak is the Flame Nebula, with clouds of bright emission and dramatic dark dust lanes. The magnificent emission region, the Orion Nebula (aka M42), lies at the upper right. Immediately to its left is a prominent reflection nebula sometimes called the Running Man. Pervasive tendrils of glowing hydrogen gas are easily traced throughout the region.
The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas – a diamond necklace of cosmic proportions. Fittingly known as the “Necklace Nebula,” this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (the Arrow).
A pair of tightly orbiting Sun-like stars produced the Necklace Nebula, which also goes by the less glamorous name of PN G054.203.4. Roughly 10,000 years ago, one of the aging stars expanded and engulfed its smaller companion, creating something astronomers call a “common envelope.” The smaller star continued to orbit inside its larger companion, increasing the bloated giant’s rotation rate until large parts of it spun outwards into space. This escaping ring of debris formed the Necklace Nebula, with particularly dense clumps of gas forming the bright “diamonds” around the ring.
The pair of stars which created the Necklace Nebula remain so close together – separated by only several million miles – that they appear as a single bright dot in the center of this image. Despite their close encounter, the stars are still furiously whirling around each other, completing an orbit in just over a day.
Again, so many galaxies...This image from the Hubble Space Telescope shows the galaxy cluster MACS J0416. This is one of six galaxy clusters being studied by the Hubble Frontier Fields program, which produced the deepest images of gravitational lensing ever made. Scientists used intra-cluster light (visible in blue) to study the distribution of dark matter within the cluster.
This view of Jupiter’s turbulent atmosphere from NASA’s Juno spacecraft includes several of the planet’s southern jet streams. Using data from Juno’s instruments, scientists discovered that Jupiter’s powerful atmospheric jet streams extend far deeper than previously imagined. Evidence from Juno shows the jet streams and belts penetrate about 1,800 miles (3,000 kilometers) down into the planet.
The storm known as the Great Red Spot is also visible on the horizon, nearly rotated out of view as Juno sped away from Jupiter at about 30 miles per second (48 kilometers per second), which is more than 100,000 mph (160,900 kilometers per hour).
This image from NASA’s Juno mission captures the northern hemisphere of Jupiter around the region known as Jet N7. The planet’s strong winds create the many swirling storms visible near the top of its atmosphere. Data from Juno helped scientists discover another, less visible effect of those winds: Jupiter’s powerful magnetic field changes over time. The winds extend more than 1800 miles (3000 kilometers) deep, where the material lower in Jupiter’s atmosphere is highly conductive, electrically. Scientists determined that the wind shears this conductive material apart and carries it around the planet, which changes the shape of the magnetic field.
This zoom video starts with a wide view of the Milky Way and ends with a close-up look at a vivid picture of an active star forming region — NGC 2467, otherwise known as the Skull and Crossbones nebula.

Closest to the Sun on March 1, and closest to planet Earth on April 23, this Comet ATLAS (C/2020 R4) shows a faint greenish coma and short tail in this pretty, telescopic field of view. Captured at its position on May 5, the comet was within the boundaries of northern constellation Canes Venatici (the Hunting Dogs), and near the line-of-sight to intriguing background galaxies popularly known as the Whale and the Hockey Stick. Cetacean in appearance but Milky Way sized, NGC 4631 is a spiral galaxy seen edge-on at the top right, some 25 million light-years away. NGC 4656/7 sports the bent-stick shape of interacting galaxies below and left of NGC 4631. In fact, the distortions and mingling trails of gas detected at other wavelengths suggest the cosmic Whale and Hockey Stick have had close encounters with each other in their distant past. Outbound and only about 7 light-minutes from Earth this Comet ATLAS should revisit the inner solar system in just under 1,000 years.
The clouds may look like an oyster, and the stars like pearls, but look beyond. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of the region. Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center. At the estimated distance of the Small Magellanic Cloud, the featured picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in this sharp multi-colored view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602.
Undulating bright ridges and dusty clouds cross this close-up of the nearby star forming region M8, also known as the Lagoon Nebula. A sharp, false-color composite of narrow band visible and broad band near-infrared data from the 8-meter Gemini South Telescope, the entire view spans about 20 light-years through a region of the nebula sometimes called the Southern Cliff. The highly detailed image explores the association of many newborn stars embedded in the tips of the bright-rimmed clouds and Herbig-Haro objects. Abundant in star-forming regions, Herbig-Haro objects are produced as powerful jets emitted by young stars in the process of formation heat the surrounding clouds of gas and dust. The cosmic Lagoon is found some 5,000 light-years away toward the constellation Sagittarius and the center of our Milky Way Galaxy. (For location and scale, check out this image superimposing the close-up of the Southern Cliff within the larger Lagoon Nebula.
This visible-light wide-field image of the region around the dark nebula LDN 483 was created from photographs forming part of the Digitized Sky Survey 2. LDN 483 appears at the center.
A zoomed in image of dark nebula LDN 483. The object is a region of space clogged with gas and dust. These materials are dense enough to effectively eclipse the light of background stars. LDN 483 is located about 700 light-years away in the constellation of Serpens (The Serpent).
This image shows a region of the Milky Way that lies within the constellation of Scorpius, close to the central plane of the galaxy. The region hosts a dense cloud of dust and gas associated with the molecular cloudIRAS 16562-3959, clearly visible as an orange smudge among the rich pool of stars at the center of the image.
Clouds like these are breeding grounds for new stars. In the center of this cloud the bright object known as G345.4938+01.4677 can just be seen beyond the veil of gas and dust. This is a very young star in the process of forming as the cloud collapses under gravity.
The young star is very bright and heavy — roughly 15 times more massive than the Sun — and featured in a recent Atacama Large Millimeter/submillimeter Array (ALMA) result. The team of astronomers made surprising discoveries within G345.4938+01.4677 — there is a large disc of gas and dust around the forming star as well as a stream of material flowing out from it.
Theories predict that neither such a stream, nor the disc itself, are likely to exist around stars like G345.4938+01.4677 because the strong radiation from such massive new stars is thought to push material away.
This image was made using the Visible and Infrared Survey Telescope for Astronomy (VISTA), which is part of ESO’s Paranal Observatory in the Atacama Desert of Chile. It is the world’s largest survey telescope, with a main mirror that measures over four meters across. The color image was produced by the VVV survey, which is one of six large public surveys that are devoted to mapping the southern sky.
The bright star in the bottom left of the image is known as HD 153220.
This zoom video starts with a wide view of the Milky Way and ends with a close-up look at the spiral galaxy NGC 3981 in the constellation of Crater (The Cup). The final view of this region was captured by FORS2, an instrument mounted on ESO’s Very Large Telescope, as part of the ESO Cosmic Gems Program.
This pan video takes a close look at the spiral galaxy NGC 3981.
The clouds may look like an oyster, and the stars like pearls, but look beyond. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of the region. Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center. At the estimated distance of the Small Magellanic Cloud, the featured picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in this sharp multi-colored view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602.
Undulating bright ridges and dusty clouds cross this close-up of the nearby star forming region M8, also known as the Lagoon Nebula. A sharp, false-color composite of narrow band visible and broad band near-infrared data from the 8-meter Gemini South Telescope, the entire view spans about 20 light-years through a region of the nebula sometimes called the Southern Cliff. The highly detailed image explores the association of many newborn stars embedded in the tips of the bright-rimmed clouds and Herbig-Haro objects. Abundant in star-forming regions, Herbig-Haro objects are produced as powerful jets emitted by young stars in the process of formation heat the surrounding clouds of gas and dust. The cosmic Lagoon is found some 5,000 light-years away toward the constellation Sagittarius and the center of our Milky Way Galaxy.

This visible-light wide-field image of the region around the dark nebula LDN 483 was created from photographs forming part of the Digitized Sky Survey 2. LDN 483 appears at the center.
A zoomed in image of dark nebula LDN 483. The object is a region of space clogged with gas and dust. These materials are dense enough to effectively eclipse the light of background stars. LDN 483 is located about 700 light-years away in the constellation of Serpens (The Serpent).
This image shows a region of the Milky Way that lies within the constellation of Scorpius, close to the central plane of the galaxy. The region hosts a dense cloud of dust and gas associated with the molecular cloudIRAS 16562-3959, clearly visible as an orange smudge among the rich pool of stars at the center of the image.
Clouds like these are breeding grounds for new stars. In the center of this cloud the bright object known as G345.4938+01.4677 can just be seen beyond the veil of gas and dust. This is a very young star in the process of forming as the cloud collapses under gravity.
