New Star Images Captured By Hubble Telescope With Help From Gravity ‘Look Like Fireworks’
The following is an excerpt from Stav Ziv | July 7, 2017 | Newsweek.com |
Scientists have looked back in time, further than they usually can with the instruments available to them, at a faraway galaxy composed of bright clumps of newborn stars. The great distance and the time it takes light to travel that far mean the galaxy appears to these Earth-bound humans as it was 11 billion years ago, or just 2.7 billion years after the Big Bang.
"When we saw the reconstructed image we said, 'Wow, it looks like fireworks are going off everywhere,'" astronomer Jane Rigby of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.
Astronomers have used the Hubble Space Telescope, taken advantage of a natural phenomenon and applied new computational methods to capture closer-up and more detailed images—about 10 times sharper than they could with the telescope alone. The findings were published in three papers: One in The Astrophysical Journal Letters and two in The Astrophysical Journal.
