The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.

In this video, I dive into the process of creating a vibrant galaxy-themed illustration using nothing but Copic markers! From ...

Past theories put a collision between the two—resulting in a new elliptical galaxy dubbed Milkomeda—as probable if not inevitable. Some predictions had that happening within 5 billion years ...

The galaxy sits in a sweet spot that allows astronomers to study it in ways that can't be applied to even our own Milky Way ...

An international team of scientists has unveiled the largest and most detailed map of the universe ever created using the James Webb Space Telescope, revealing nearly 800,000 galaxies stretching ...

Galaxies are thought to form and grow by collisions and mergers, and elliptical galaxies may be the ultimate result of this ...

Dark matter clumps the same way stars in an elliptical galaxy gather into a big ellipsoid. Stars interact with their neighbors in essentially a frictionless manner, otherwise those ellipticals ...

Imagine looking at a particular massive (usually yellow and elliptical) galaxy that has a faint blue galaxy exactly behind it, Marshall explains. “It's not that you don't see that background galaxy ...
