| Description |
The combination of Webb’s super powerful vision and a magnifying trick of gravity is allowing astronomers to resolve things never before seen in the early universe. 🔎 Imagine having a giant magnifying glass in space that could help us view the most distant galaxies more easily. Luckily, we can use galaxy clusters! They’re so massive their gravity can bend and magnify the light of objects behind them. In the case of galaxy MACS0647-JD, it is being magnified by the galaxy cluster, called MACS0647, in front of it. A side effect of this is that magnified objects can look warped and even appear multiple times around the edges of the galaxy cluster. The JD object appears 3 times, as shown in the sidebar here. See the close-up views of galaxy MACS0647-JD on the right? Hubble showed just one object, but Webb shows that there are two. Are they two galaxies, perhaps merging? Or two clumps of stars within a galaxy? We don’t know yet, but Webb could help us figure it out.

The background is black and there are galaxies scattered all around, some looking like spirals, others like discs. They range in color from blue to golden to orange. In the center is a prominent, glowing cluster of galaxies and in the foreground, there are a few stars with prominent diffraction spikes. There are also 3 numbered small boxes outlined in white. These are 3 views of the same distant galaxy, which have been magnified, distorted, and repeated due to the gravitational lensing effect of the galaxy cluster. Enlarged images of what is in these boxes appear in a column down the right side. They are labeled JD 1, JD 2, and JD 3. Although Hubble showed just one object for this galaxy, Webb shows 2 distinct objects, one larger and one smaller.] |
