JWST-ER1: The Einstein Ring

Using the Hubble Space Telescope, astronomers discovered an incredible cosmic object in the data from JWST, and they stumbled upon it without a particularly systematic search .

The object is a gravitational lens, which magnifies a distant galaxy.

In fact, it’s so far away that its light has taken 103 billion years to reach us.

This distant gravitational lensing object is actually called an Einstein lens, and it can be used to study dark matter.

By looking at the light of these stars, the team estimated that in total they weigh about 110 billion times the mass of the Sun.

The team found the object by eyeballing the COSMOS-Web data, and now it will be interesting to see what future focused
