Astronomers reported Monday that the probability of the two spiral galaxies colliding is less than previously thought, with a ...

That makes its stellar-mass surface density extremely high—among the densest observed in any galaxy. This level of compactness and mass density has only been seen before in massive elliptical ...

Spirals are only one of four major classifications for galaxies; the others are elliptical, irregular and peculiar. Elliptical galaxies would be better called spheroidal; they can be spherical but ...

We have measured how far apart elliptical galaxies are from one another today. "Using these data and taking into account the characteristics of this group of galaxies, we were then able to use the ...

It's what is known as a peculiar galaxy – one that has characteristics of both a highly structured spiral galaxy, and a more diffuse elliptical galaxy, thus fitting into neither category, but hanging ...

with varying intensities and characteristics. The source showed a distinct period of heightened activity in June 2024, producing 17 bursts in one month. The bursts were located 40,000 light-years from ...

The signal has been linked to the outskirts of an ancient, dead, elliptical galaxy. This presents an unprecedented home for a phenomenon previously associated with much younger galaxies.

My collaborators and I have just tackled one of astrophysics’ enduring mysteries: how massive elliptical galaxies can form. Now, for the first time, we have solid observational evidence that ...

elliptical galaxies do not typically contain the ingredients necessary for new stars to form. The active star formation, which powers the bright center, aligns more with the characteristics of a ...

Let’s explore the seven largest black holes in the universe, which have various characteristics ... 1101 is a lenticular galaxy. These galaxies fall between spiral and elliptical in terms ...
