Webb Surprises Astronomers with Never-Before-Seen Details of the Early Universe

MACS0647's immense gravity works as a cosmic lens, bending and magnifying light from the more distant MACS0647-JD system. It also triple-lensinged the JD system, causing its picture to appear in three different places. These photos are labelled JD1, JD2, and JD3 and are emphasized with white boxes. The redshift of MACS0647-JD is roughly 11, putting it in the first 400 million years after the Big Bang. The diagonal, long line The lengthy, diagonal line running through the photograph is a diffraction spike from a brilliant star just beyond the frame.

Please keep in mind that this graphic depicts data from Webb science in progress, which has not yet been peer-reviewed.

[Image Description: A James Webb Space Telescope image of galaxy cluster MACS0647 and the very distant galaxy MACS0647-JD. At left, the cluster appears as a sea of galaxies on a black background and three small boxes outlined in white mark the locations of the three images of galaxy MACS0647-JD. Enlarged images of these boxes appear in a column down the right side of the screen]
