Lucie, astrophysicienne : la tête dans les étoiles.

ALT Webb Senior Project Scientist Jane Rigby speaks to a crowd in an auditorium, where multiple rows of people can be seen. Rigby is standing next to a podium with the words “STScI Space Telescope Science Institute.” Toward the right is a portion of a large screen displaying a presentation slide titled “Summary.”

ALT STScI and ESA’s Macarena Garcia Marin stands behind a podium with the words “STScI Space Telescope Science Institute.” She is speaking to a crowd, where multiple rows of people can be seen. Toward the right, a large screen is displaying a presentation slide titled “Outline.” The slide text reads, Data to Papers Initiative, JWST Users Committee, Cycle 3 timeline, Proposals resources, and Do you have a News-Worthy result?

ALT This is the deepest and sharpest infrared image of the early universe ever taken. The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center. Credits: NASA, ESA, CSA, and STScI

ALT An image of the Earth, a round ball, set against the blackness of outer space. Through swirling clouds, the continent of Africa and the island of Madagascar can be seen; Antarctica is just visible at the very bottom of the Earth, and the Arabian peninsula at the top. The Atlantic and Indian Oceans are a deep, rich blue, giving this photo its common name: the Blue Marble.
