Far out: NASA space telescope's 1st cosmic view goes deep
Washington(AP): Our view of the universe just expanded: The first image from NASA's new space telescope unveiled Monday is brimming with galaxies and offers the deepest look of the cosmos ever captured.
The first image from the 10 billion James Webb Space Telescope is the farthest humanity has ever seen in both time and distance, closer to the dawn of time and the edge of the universe. That image will be followed Tuesday by the release of four more galactic beauty shots from the telescope's initial outward gazes.
The deep field" image released at a White House event is filled with lots of stars, with massive galaxies in the foreground and faint and extremely distant galaxies peeking through here and there. Part of the image is light from not too long after the Big Bang, which was 13.8 billion years ago.
Seconds before he unveiled it, President Joe Biden marveled at the image he said showed the oldest documented light in the history of the universe from over 13 billion -- let me say that again -- 13 billion years ago. It's hard to fathom.
The busy image with hundreds of specks, streaks, spirals and swirls of white, yellow, orange and red is only one little speck of the universe, NASA Administrator Bill Nelson said.
The pictures on tap for Tuesday include a view of a giant gaseous planet outside our solar system, two images of a nebula where stars are born and die in spectacular beauty and an update of a classic image of five tightly clustered galaxies that dance around each other.
The world's biggest and most powerful space telescope rocketed away last December from French Guiana in South America. It reached its lookout point 1 million miles (1.6 million kilometers) from Earth in January. Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool.
The plan is to use the telescope to peer back so far that scientists will get a glimpse of the early days of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus.
Webb is considered the successor to the highly successful, but aging Hubble Space Telescope. Hubble has stared as far back as 13.4 billion years. It found the light wave signature of an extremely bright galaxy in 2016. Astronomers measure how far back they look in light-years with one light-year being 5.8 trillion miles (9.3 trillion kilometers).
Webb can see backwards in time to just after the Big Bang by looking for galaxies that are so far away that the light has taken many billions of years to get from those galaxies to our telescopes, said Jonathan Gardner, Webb's deputy project scientist said during the media briefing.
How far back did that first image look? Over the next few days, astronomers will do intricate calculations to figure out just how old those galaxies are, project scientist Klaus Pontoppidan said last month.
The image is spectacularly deeper (than a similar one taken by Hubble), but it's unclear how far back we're looking,? Richard Ellis, professor of astrophysics at University College London, said by email. More info is needed.
The deepest view of the cosmos is not a record that will stand for very long, Pontoppidan said, since scientists are expected to use the Webb telescope to go even deeper.
Thomas Zurbuchen, NASA's science mission chief said when he saw the images he got emotional and so did his colleagues: It's really hard to not look at the universe in new light and not just have a moment that is deeply personal.
At 21 feet (6.4 meters), Webb's gold-plated, flower-shaped mirror is the biggest and most sensitive ever sent into space. It's comprised of 18 segments, one of which was smacked by a bigger than anticipated micrometeoroid in May. Four previous micrometeoroid strikes to the mirror were smaller. Despite the impacts, the telescope has continued to exceed mission requirements, with barely any data loss, according to NASA.
NASA is collaborating on Webb with the European and Canadian space agencies.
I'm now really excited as this dramatic progress augurs well for reaching the ultimate prize for many astronomers like myself: pinpointing Cosmic Dawn the moment when the universe was first bathed in starlight, Ellis said.

Rishabh Pant's troubles continue as Punjab Kings push LSG towards exit door
Dharamsala, May 4 (PTI): Rishabh Pant lost the grip on his bat and the match simultaneously as Punjab Kings rode on heroics from the two 'Singhs' -- Prabhsimran and Arshdeep -- to literally push Lucknow Super Giants to the brink of elimination with a 37-run win in an IPL match here on Sunday.
It was Prabhsimran's 48-ball 91 that formed the cornerstone of Punjab Kings' unassailable 236 for 5 and any hopes of a remarkable chase was nipped in the bud by Arshdeep's (3/16 in 4 overs) now familiar Powerplay spell which summarily destroyed the opposition top-order.
This time, he got the three top run getters -- Mitchell Marsh (0), Aiden Markram (13) and the ever-dangerous Nicholas Pooran (6) -- to swing the match decisively in Punjab's favour. Ayush Badoni's (74 off 40 balls) effort was a good one albeit it came for a losing cause.
LSG were finally restricted to 199 for 7 in 20 overs and even if they win their last three games and get to 16 points from 14 games, their net run-rate can make things difficult for them.
Punjab Kings are now placed second with 15 points from 11 games and one more win could possibly clinch a place in top four for them.
But what is becoming an eyesore is LSG's Rs 27 crore worth skipper Pant's inexplicable approach which has fetched him a dismal 128 runs in 11 innings at a sub-100 strike-rate (99.22).
On the day, he scored 18 off 17 balls and that he is completely out of sync was evident in the manner he tried to throw the proverbial kitchen sink at an Azmatullah Omarzai delivery. There was no control in his shot as the bat took off on parabolic curve towards square leg and the ball went towards deep point.
Pant's misery was a testimony of LSG's wretched campaign that was lost at the auction table when the owner decided to go with a sub-standard bowling attack based on a half-fit talented pacer Mayank Yadav.
Mayank has already lost at least 10-15 yards of pace post rehabilitation under the watch of Nitin Patel at the National Cricket Academy.
On Sunday, he went for 60 runs off four overs with half a dozen of sixes struck off his bowling.
The pint-sized Prabhsimran packed a mean punch in his strokes as he blasted his way to a 48-ball 91 with the help of six fours and seven sixes.
The Punjab keeper-batter should have got his second IPL hundred but an ambitious switch hit off Digvesh Rathi saw him head back to the pavilion, nine runs short of what would have been a deserving milestone.
Towards the end, Shashank Singh scored 33 off 15 balls to take PBKS to what looked like an unassailable total. There were 16 sixes hit by Pujab Kings with 13 coming off pacers.
Prabhsimran was initially a passive partner as it was Australian Jos Inglis who launched the first attack with a hat-trick of sixes off Mayank Yadav, whose speed has decreased by at least 15 kmph post his intense rehab under Nitin Patel at the BCCI's erstwhile National Cricket Academy to recover from back injury.
However, once Inglis was dismissed, Prabhsimran, along with skipper Shreyas Iyer (45 off 25 balls), took control of the game. They were only helped by some atrocious fielding from Avesh Khan, who would probably go down as the worst fielder in the 18-year history of IPL.
Adding insult to injury, Prabhsimran took the tall MP fast bowler to the cleaners as he was pulled over mid-wicket for back-to-back maximums. Khan went for 57 in four overs and if around 15 runs due to his misfielding is added, he caused the maximum damage for his team.
The duo of Prabhsimran and Iyer added 78 runs in 7.5 overs before Rathi, LSG's best bowler on view, became the first spinner in the current season to account for Punjab Kings skipper's wicket.
But Prabhsimran continued like a man possessed and LSG bowlers were guilty of feeding to his strengths throughout the innings.
