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.

Sensex rises nearly 295 pts to close at 2025-high on foreign fund inflows, drop in crude prices
Mumbai, May 5 (PTI): Benchmark BSE Sensex climbed nearly 295 points to close at an over four-month high on Monday following sustained foreign fund inflows and a sharp correction in global crude oil prices.
Rising for the second in a row, the 30-share BSE barometer gained 294.85 points or 0.37 per cent to settle at 80,796.84, marking its highest close in 2025 so far. During the day, it jumped 547.04 points or 0.67 per cent to 81,049.03.
The NSE Nifty rose 114.45 points or 0.47 per cent to 24,461.15, its highest closing level in 2025.
Among Sensex firms, Adani Ports jumped 6.29 per cent amid reports that Gautam Adani's representatives met with US administration officials to seek the dismissal of criminal charges in a bribery probe. All other listed Adani group stocks, including Adani Enterprises, Adani Ports, Adani Power and Adani Green Energy, ended with sharp gains.
Bajaj Finserv, Mahindra & Mahindra, Eternal, Power Grid, ITC, Tata Motors, Asian Paints and Hindustan Unilever were also among Sensex gainers.
Among the laggards, Kotak Mahindra Bank tanked 4.57 per cent after the firm reported a 7.57 per cent decline in consolidated net profit to Rs 4,933 crore for the March quarter of FY25, primarily due to elevated stress in the microlending book.
State Bank of India, Axis Bank, Titan and IndusInd Bank were among the other losers.
State Bank of India dipped over 1 per cent after it reported an 8.34 per cent decline in consolidated net profit to Rs 19,600 crore for the January-March quarter compared to Rs 21,384 crore a year ago, impacted by a decline in net interest margins.
Foreign Institutional Investors (FIIs) bought equities worth Rs 2,769.81 crore on Friday, according to exchange data.
Foreign investors injected Rs 4,223 crore into the country's equity market in April, as they turned net buyers for the first time in three months amid a blend of favourable global cues and robust domestic fundamentals.
The inflow of foreign capital came last month following a back-to-back net outflow of Rs 3,973 crore in March, Rs 34,574 crore in February, and Rs 78,027 crore in January.
"The market has sustained its positive momentum, though the level of optimism has decreased. Continued foreign inflows and record GST collections in April indicate resilience in economic activity, fostering mild hopefulness. A weak dollar and a decline in oil prices have further bolstered FII sentiment.
"However, the market's momentum is moderating, with action shifting from broad-based movements to stock and sector-specific trends based on results," Vinod Nair, Head of Research, Geojit Investments Limited, said.
The BSE midcap gauge jumped 1.45 per cent and smallcap index climbed 1.23 per cent.
Among sectoral indices, services jumped the most 2.99 per cent, followed by oil & gas (1.95 per cent), auto (1.88 per cent), consumer discretionary (1.58 per cent), utilities (1.50 per cent) and energy (1.49 per cent).
Bankex emerged as the only loser.
As many as 2,563 stocks advanced while 1,459 declined and 180 remained unchanged on the BSE.
Markets in South Korea, Japan, China and Hong Kong were closed due to holidays.
European markets were trading on a mixed note.
US markets ended significantly higher on Friday.
Global oil benchmark Brent crude dropped 1.45 per cent to USD 60.40 a barrel.
The 30-share BSE benchmark gauge settled 259.75 points, or 0.32 per cent, higher at 80,501.99 on Friday. The Nifty eked out a marginal gain of 12.50 points, or 0.05 per cent, to settle at 24,346.70.
