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 ...

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 ...

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

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 ...

This was a big surprise to the research team, as quasars hosting jets are typically elliptical-shaped, and its suspected that messy mergers with other galaxies are what funnel gas toward the black ...

Most of the quasars astronomers have detected are old, the product of multiple galaxy collisions leaving them with an elliptical shape. When observing quasar J0742+2704, Achenbach was surprised to ...

"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 ...
