President Joe Biden released one of Webb's first images Monday at the White House during a preview event with NASA Administrator Bill Nelson.
The Southern Ring Nebula, also called the"Eight-Burst," is 2,000 light-years away from Earth. This large planetary nebula includes an expanding cloud of gas around a dying star.
The space telescope's view of Stephan's Quintet will reveal the way galaxies interact with one another. This compact galaxy group, first discovered in 1787, is located 290 million light-years away in the constellation Pegasus. Four of the five galaxies in the group"are locked in a cosmic dance of repeated close encounters," according to a NASA statement.
The targets were selected by an international committee, including members from NASA, the European Space Agency, the Canadian Space Agency and the Space Telescope Science Institute in Baltimore.These will be the first of many images to come from Webb, the most powerful telescope ever launched into space. The mission, originally expected to last for 10 years, has enough excess fuel capability to operate for 20 years, according to NASA Deputy Administrator Pam Melroy.
"Webb can see backwards in time just after the big bang by looking for galaxies that are so far away, the light has taken many billions of years to get from those galaxies to ourselves," said Jonathan Gardner, Webb deputy senior project scientist at NASA, during a recent news conference."Webb is bigger than Hubble so that it can see fainter galaxies that are further away."
The initial goal for the telescope was to see the first stars and galaxies of the universe, essentially watching"the universe turn the lights on for the first time," said Eric Smith, Webb program scientist and NASA Astrophysics Division chief scientist."The James Webb Space Telescope will give us a fresh and powerful set of eyes to examine our universe," Smith wrote in an update on NASA's website."The world is about to be new again.
