Lonesome Planet
July’s Thunder Supermoon Wenesday night
At 222,000 miles at perigee, it should be slightly bigger, and brighter, than the average full m😯on


An astronomical animation shows a possible impact where Comet K2 is pulled into the moon’s gravitational field,
And crashes into it.

An improbable event, as at closest, K2 will be 1.8 AU from Earth; at perigee Wednesday, the moon will be 0.00148 astronomical units from our tiny blue marble...

Those of us who had hoped to gasp over the closest earth approach on Thursday night of
comet C/2017 K2 (PanSTARRS) — or “K2″ for short will have to confront a beautiful spoiler Wednesday
Night. The Super Thunder Full Moon.




At 222,000 miles at perigee, it will be much brighter than the average full moon,
Saturating the night, and obliterating an eight magnitude K2.

It already seemed to be full last night (takened with an iPad)




Oh, well. K2 should be visible the rest of the year to see, with a medium size telescope

WHAT TIME WILL NASA RELEASE JWST’S IMAGES?

Things get started this afternoon at the White House. For weeks now, NASA had been planning to release the images all together on the morning of July 12th, but over the weekend, the agency surprised everyone by adding a last-minute White House briefing on July 11th at 5PM ET. Now, President Joe Biden will reveal one of the images first this afternoon, with NASA administrator Bill Nelson providing remarks.

HAL is a StarChild
This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.


Stephan’s Quintet, a visual grouping of five galaxies, is best known for being prominently featured in the holiday classic film, “It’s a Wonderful Life.” Today, NASA’s James Webb Space Telescope reveals Stephan’s Quintet in a new light. This enormous mosaic is Webb’s largest image to date, covering about one-fifth of the Moon’s diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The information from Webb provides new insights into how galactic interactions may have driven galaxy evolution in the early universe.

With its powerful, infrared vision and extremely high spatial resolution, Webb shows never-before-seen details in this galaxy group. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster.


Some stars save the best for last.

The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.

Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.

Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one – clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects.

First Light

It would be helpful if side by side images were posted of the pre- JWST,
With the JWST shots just released.

To my untrained eye, except for the color differentiation, the 10x sharper
WST images are no more spectacular than those of the HST. My bad?

Perhaps the wonder of the WST will manifest its magic when peering further into deep
Time/space. When vast hydrogen clumps coalesced into hydrogen stars, and stars and
Gas become gravitationally bounded into many individual spiral/elliptical (?) galaxies, some
14 billion years ago.
At the beginnings of our parallel universe.

How did dark matter influence the formation of ordinary matter, an extraordinary
Quest for the future.

Hubble’s Deep Field (100 hours, or so, later).
The WT should be faster, and many times sharper in the dust free IR spectrum.




ADDENDA:

Hubble? (Note six point foreground stars)


Webb?


Ah, lord, I can see the light, now

Hubble


Webb



10x sharper is Sharp!

For Theravada Buddhists, this full moon is known as Asalha Puja, also called Dharma Day

While JWST is the best, and the most brilliant of astronomical wonders, the naming of astronomy’s
New window into the cosmos has been called into question.

Named after an administrator, by an administrator, many scientists in the astronomical field have signed a petition
To rename the telescope.

That James Webb actively persecuted, and routed gay scientists and workers while he was chief administrator of NASA
In the sixties is now an issue of concern today.

NASA has been saying no, will there be a shift.



Tally Ho. Shine on!

The JWST by any other name would still peer deep into space and time,
giving mankind enlightening Insights into our parallel universe’s primordial origins,
And our own.

Unobscured by the vaguries of policies, and politics. A large step indeed.

In awe, from our island universe.

It actually looks like a giant Hershey’s Kiss, populated by lilliputian kisses.
They are the upgraded version, attired in gold instead of aluminum,
For 99.9% reflectivity.

Note the absence of the six diffraction spikes (plus a fainter, smaller set of spikes) due to the non-hexagon point spread function of the belle shape.
