The idea is that these elliptical galaxies arrive at their final shape through collisions across the ages of the ... Famous Dark Streaks On Mars May Not Be What We Were Hoping For. 23 hours ago. 19.

It has a smooth-looking, armless shape, like an elliptical galaxy, and a disk with a low star-formation rate. However, it has relatively younger and newer stars forming in its central region.

Gjergo continued: "We find that at the peak of their formation, elliptical galaxies must have been 10,000 times brighter than their counterparts today.

There are also elliptical galaxies, which are large and spherical rather than flat, similar to a rugby ball. The latter don’t produce new stars but are dominated by stars formed more than 10 ...

Scientists have spotted a defiant galaxy. Located nearly 1 billion light-years from Earth, the galaxy 2MASX J23453268−0449256 is a spiral, like our home the Milky Way.Yet it does something ...

A Hubble image captures a distant galaxy, HerS 020941.1+001557, whose light is magnified and bent by a foreground elliptical galaxy, SDSS J020941.27+001558.4, forming a partial Einstein ring.

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 ...

Galaxy Arp 184, however, we are seeing from an angle, so it looks different. More than that, though, Arp 184 is skewed so that it isn’t perfectly spiral shaped.

The unusual galaxy NGC 4694 has traits unique to the two main galaxy types, spiral and elliptical. (Image credit: ESA/Hubble & NASA, D. Thilker) What it is: The galaxy NGC 4694, a member of the ...
