Webb spots a second lensed supernova in a distant galaxy

In November 2023, the James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 ...

Measuring the distances to galaxies with space telescopes

One of the James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that we identify samples of ...

NASA telescopes discover record-breaking black hole

Astronomers have discovered the most distant black hole yet seen in X-rays, using NASA telescopes. The black hole is at an early stage of growth that had never been witnessed before, where its mass is similar to that of its ...
