Default NASA's Webb Telescope Launches to See First Galaxies, Distant Worlds

NASA's Webb Telescope Launches to See First Galaxies, Distant Worlds
Quote:
NASA’s James Webb Space Telescope launched at 7:20 a.m. EST Saturday on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America.

A joint effort with ESA (European Space Agency) and the Canadian Space Agency, the Webb observatory is NASA’s revolutionary flagship mission to seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets.

“The James Webb Space Telescope represents the ambition that NASA and our partners maintain to propel us forward into the future,” said NASA Administrator Bill Nelson. “The promise of Webb is not what we know we will discover; it’s what we don’t yet understand or can’t yet fathom about our universe. I can’t wait to see what it uncovers!”

Thought I recognized the voice of Rob Navias, NASA's long-time PAO over the French announcer.

Too bad it was overcast and we couldn't see the Ariane staging or anything. Still glad JWST got uphill successfully. I'm waiting for new Earth-like exoplanet discoveries. Hopefully the telescope can get a better look at the Gliese and TRAPPIST systems and determine if any of their planets have liquid water and oxygen atmospheres. Maybe even nearer Sun-like stars like Alpha Centauri and Tau Ceti will have an Earth II. Possibly that Sun-like star 1,800 LY away they think the "Wow!" signal came from, too.

Post The first 29 days after launch



Quote:
The greatest origin story of all unfolds with the James Webb Space Telescope. Webb's launch is a pivotal moment that exemplifies the dedication, innovation, and ambition behind NASA and its partners, the European Space Agency (ESA) and Canadian Space Agency (CSA), but it is only the beginning. The 29 days following liftoff will be an exciting but harrowing time. Thousands of parts must work correctly, in sequence, to unfold Webb and put it in its final configuration, all while it flies through the expanse of space alone, to a destination nearly one million miles away. As the largest and most complex telescope ever sent into space, the James Webb Space Telescope is a technological marvel. By necessity, Webb takes on-orbit deployments to the extreme. Each step can be controlled expertly from the ground, giving Webb’s Mission Operations Center full control to circumnavigate any unforeseen issues with deployment.

Let's hope this deployment phase of the mission goes well

I hope so, too. In addition to JWST at the L2 point in space, a facility on the far side of the Moon would be good for radio astronomy, free from terrestrial interference for things like SETI and other pursuits.

Thumbs up First images

Quote:
The wait is finally over.

The team behind NASA's James Webb Space Telescope released some of the first images from the much-anticipated observatory on Friday (Feb. 11). The main photo, which doesn't even hint at the power Webb will bring to the universe once it's fully operational, shows a star called HD 84406 and is only a portion of the mosaic taken over 25 hours beginning on Feb. 2, during the ongoing process to align the observatory's segmented mirror.

"The entire Webb team is ecstatic at how well the first steps of taking images and aligning the telescope are proceeding," Marcia Rieke, principal investigator of the instrument that Webb relies on for the alignment procedure and an astronomer at the University of Arizona, said in a NASA statement.

JWST is now 48 days out from its Christmas Day launch and in the midst of a commissioning process expected to last about six months. The telescope spent the first month unfolding from its launch configuration and trekking out nearly 1 million miles (1.5 million kilometers) away from Earth.

During the bulk of the remaining time, scientists are focusing on waking and calibrating the observatory's instruments and making the minute adjustments to the telescope's 18 golden mirror segments that are necessary for crisp, clear images of the deep universe.

The process is going well, according to NASA.

"This initial search covered an area about the size of the full moon because the segment dots could potentially have been that spread out on the sky," Marshall Perrin, the deputy telescope scientist for Webb and an astronomer at the Space Telescope Science Institute, said in the same statement. "Taking so much data right on the first day required all of Webb's science operations and data processing systems here on Earth working smoothly with the observatory in space right from the start. And we found light from all 18 segments very near the center early in that search! This is a great starting point for mirror alignment."

Still, the telescope has a long way to go, as today's image of HD 84406 shows.

"The first images are going to be ugly," Jane Rigby, Webb operations project scientist, said during a news conference held on Jan. 8 as the telescope began the process of unstowing its mirrors. "It is going to be blurry. We'll [have] 18 of these little images all over the sky."

And the photograph does indeed show multiple views of HD 84406, the star that JWST scientists recently announced they had chosen to look at first. "Star light, star bright … the first star Webb will see is HD 84406, a sun-like star about 260 light-years away," NASA officials wrote on Twitter on Jan. 28.
HD 84406 is in the constellation Ursa Major, or Big Bear, but is not visible from Earth without a telescope. But it was a perfect early target for Webb because its brightness is steady and the observatory can always spot it, so launch or deployment delays wouldn't affect the plan.

Oddly, JWST won't be able to observe HD 84406 later in its tenure; once the telescope is focused, this star will be too bright to look at. Previously, JWST personnel have said that the telescope will be seeing fairly sharply by late April.

Even as the JWST works to hone its vision, a second key process is taking place in the background as the observatory sends the remaining heat from its time on Earth out into space. Because Webb is tuned to study the universe in infrared light, which also registers as heat, the observatory must be incredibly cold to obtain accurate data.

NASA scientists expect that the golden primary mirror will reach temperatures as low as minus 370 degrees Fahrenheit (minus 223 degrees Celsius or 50 degrees Kelvin); instruments must be even colder, according to an agency statement.

In addition to the image of HD 84406, NASA also shared a "selfie" image that the observatory took using a special lens targeting the observatory's primary mirror to assist during the alignment process.

All told, scientists are thrilled about the observatory's progress.

"Launching Webb to space was of course an exciting event, but for scientists and optical engineers, this is a pinnacle moment, when light from a star is successfully making its way through the system down onto a detector," Michael McElwain, Webb observatory project scientist, NASA's Goddard Space Flight Center said in the statement.

This is not the greatest video, but it would be amazing if JWST did detect extraterrestrial life, not necessarily intelligent aliens or civilizations, but biosignatures on distant exoplanets.

I really hope JWST can locate an Earth II exoplanet fairly close to us, say within 20 light-years.

Watch President Biden unveil the 1st James Webb Space Telescope science image today!

https://www.space.com/james-webb-spa...photos-webcast

Hopefully, Dementia Joe won't say, "Hello Neil and Buzz, I'm speaking to you from the Oval Room at the White House," but try to focus on the photos.

No, but he'll probably call it the Hubble Space Telescope.

Default First Images from the James Webb Space Telescope

First Images from the James Webb Space Telescope
Quote:
On Monday, July 11, President Joe Biden released one of the James Webb Space Telescope’s first images in a preview event at the White House in Washington. NASA, in partnership with ESA (European Space Agency) and CSA (Canadian Space Agency), will release the full set of Webb’s first full-color images and spectroscopic data during a televised broadcast beginning at 10:30 a.m. EDT (14:30 UTC) on Tuesday, July 12, from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

This first image from NASA’s James Webb Space Telescope is the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

Talking Jwst

Beautiful thing, built by Ball Aerospace and Northrop Grumman shame its deployed at an unserviceable distance form earth incase its damaged by a space rock. Nasa teevee has a fat nigger sow doing the introduction to the 'first images' ...shame that this mission, which started over two decades ago will probably be Nasa's last hurrah.


watching Nasa Live ...


itz hard to listen to this nigger bitch, she mispronounces half of what she reads off the teleprompter ...hahaha they cant even run the sound system correctly, one of the pols had to hand another his mike because it didnt work

Cool Carina nebula

After wasting time watching Nasa's awful production of the "rollout" of the "first" JWST images they displayed the space telescopes image of the Carina Nebula which unfortunately isn't visible in the Northern hemisphere (dammit) I have a 18" f4 dob that was left here by a former girlfriend that I could have viewed it with. This is what it looks like with the JWST ...I want a digital scope now!
