Galaxies may not be as simple as "young and blue" or "old and red." A new idea from astrophysicist Charles Steinhardt ...

Some galaxies that should have ceased forming stars long ago are defying expectations. Anew theory proposes the existence of ...

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by ...

Such dead galaxies are more formally referred to as being "quiescent," or "quenched." Early dead galaxies seen by the JWST have been referred to as "red and dead" galaxies due to their lack of massive ...

As a remarkable improvement over previous IRAC image (above), JWST’s unprecedented spatial resolution and high IR sensitivity reveals the morphological details of the red spiral galaxies (below ...

Traditionally, astronomers have grouped galaxies into two different categories: blue, which are young and actively forming stars, and red, which are older and have ceased star formation.
