but sometimes they collide with other spirals and form elliptical galaxies. We see these three-dimensional egg-shaped blobs as two-dimensional ellipses on the sky. The merger process triggers ...

The idea is that these elliptical galaxies arrive at their final shape through collisions across the ages of the universe. This is what will happen to Andromeda and the Milky Way when they merge ...

For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy—an unprecedented home for a phenomenon previously associated with much ...

Rethinking the Underlying Trigger of Quasar Jets Building on the groundbreaking 2020 discovery of newborn jets in several ...

Spiral galaxies have a thin, pancake-shaped disk, with a spherical bulge at the center. Within the disk, the brightest stars trace out the characteristic spiral pattern. Elliptical galaxies are ...

Typically, summer internships are about gaining work experience and networking. But for Midshipman Olivia Rae Achenbach, her ...

Quasars are the most luminous type of active galaxy. They emit light across the electromagnetic spectrum, produce powerful ...

"We typically see quasars as older galaxies that have grown very massive, along with their central black holes, after going through messy mergers and have come out with an elliptical shape," said ...
