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.

Nitish likely to resign as Bihar CM after last meeting of cabinet on April 14
Patna (PTI): Bihar inched towards a political transition on Sunday with Chief Minister Nitish Kumar convening a meeting of his cabinet on April 14, following which the JD(U) president is likely to relinquish the post to make way for a BJP-led government.
According to a notification issued by the cabinet secretariat department, the meeting will take place at 11 am, after which the longest-serving CM of the state, who got elected to the Rajya Sabha last week, was expected to submit his resignation to Governor Syed Ata Hasnain.
Earlier, Kumar's close aide and JD(U) national working president Sanjay Kumar Jha had told reporters that the process of formation of a new government was likely to "roll out after April 13".
Meanwhile, the BJP, which has been approaching the prospect of having its first- ever chief minister in the state with considerable restraint, got down to business and named Shivraj Singh Chouhan as a "central observer", who would oversee the change of guard.
A statement issued by the BJP headquarters in Delhi said the parliamentary board has appointed Chouhan, a Union minister and a multiple-term former CM of Madhya Pradesh, as “central observer for electing the leader of legislature party in Bihar”.
Senior JD(U) leader and Minister for Parliamentary Affairs, Vijay Kumar Chaudhary, had said here earlier in the day "the new chief minister will be elected by the NDA, upon the recommendation of the BJP, which has a big role to play".
Speculations are doing the rounds that Deputy Chief Minister Samrat Choudhary, who holds the crucial Home portfolio in the outgoing government, is the frontrunner among contenders for the top job.
BJP leaders in the state, who have been making frantic visits to Delhi in the recent past, are keeping their cards close to the chest.
"Who will be the next CM is a decision to be taken by our central leadership," minister Dilip Jaiswal, who is a former state BJP president, had said a day ago, adding, "I am not at all in the race".
Other than Choudhary, who had joined the BJP less than a decade ago, those whose names are doing the rounds include Union Minister of State for Home Nityanand Rai and state ministers Lakhendra Paswan and Shreyasi Singh.
According to BJP sources, all these leaders fit the bill in different ways. Choudhary is a ‘Koeri’, and his elevation could ensure that the ‘Luv Kush’ (Kurmi Koeri) equation nurtured by Kumar during his 20-year-rule remained intact in favour of the NDA, after the JD(U) supremo's departure.
Rai is a Yadav and brings the promise of support of the largest caste group in Bihar, which has been with Lalu Prasad's RJD, the BJP's principal rival in the state, for decades.
Paswan is a Dalit and his elevation could help the BJP transcend its "pro-upper caste" image, which brings its own disadvantages in the Hindi heartland, where the Mandal agitation of the 1990s has cast a long shadow, the sources said.
Singh, in her 30s, is an upper caste Rajput, but her elevation could be projected as the party giving preference to young blood.
Moreover, the party has also been trying to present itself as a champion of gender equality, by pushing through the ‘Nari Shakti Vandan Adhiniyam’ that ensures 33 per cent reservation to women in both Houses of Parliament.
However, the BJP sources admitted that there was a strong possibility of the central leadership springing a "surprise", citing examples of many states ruled by the party, where less fancied leaders have landed the top job in the recent past.
Actor-turned-politician Shatrughan Sinha, a Trinamool Congress MP who spent nearly three decades in the BJP, had said, while commenting on the political situation in Bihar that "we have plenty of deserving people here but we must be beware of a baba who may arrive with a parchi".
The allusion was to Rajasthan, where Bhajan Lal Sharma was named the chief minister two years ago at a legislature party meeting, where Defence Minister Rajnath Singh was seen on camera taking out a piece of paper with the name of the first-term MLA written on it.
