The targets include galaxies, nebulas, and a giant planet outside our Solar System.
. It’s also designed to study objects throughout our Universe in unprecedented detail, giving us insight into our distant Solar System, planets outside our cosmic neighborhood, asteroids, exotic stars in the deepest reaches of space, and more.
To get its very first images, JWST observed these target objects and regions of space for 120 hours, collecting five days’ worth of data. Up until now, we didn’t know much about what the first images of JWST would be, though we got some hints from NASA leadership. Thomas Zurbuchen, NASA’s associate administrator for science, revealed that we’d see the light from the atmosphere of a planet outside our Solar System, known as an exoplanet.
The target list for this breakthrough moment was selected by an international team of people from NASA, the European Space Agency, the Canadian Space Agency, and the Space Telescope Science Institute, which oversees the operations and science of JWST. Some of the targets we’ve seen before, thanks to images captured by JWST’s predecessor, the Hubble Space Telescope. But JWST’s mirror is nearly three times wider than that of Hubble; plus, JWST sits roughly 1 million miles from Earth, whereas Hubble is in low Earth orbit. Compared to the Hubble images, JWST’s images should be even more detailed.
NASA is set to reveal the images on July 12th at 10:30AM ET. And they are sure to be breathtaking. “What I have seen just moves me,” Pam Melroy, a former astronaut and current deputy administrator of NASA, said during a press conference, “as a scientist, as an engineer, and as a human being.”
