Sentences with phrase «galaxy in the coma»

Grasping in the Dark The newfound dim galaxies in Coma are strange beasts, and they hark back to some of the faint galaxies first uncovered in the late 1980s.

In a 2015 study, Pieter van Dokkum of Yale University and colleagues announced they had unearthed 47 never - before - seen, Milky Way - sized yet extremely diffuse (spread out, so relatively dim) galaxies in the Coma Cluster of galaxies, among the most studied in astronomy.

This boatload had gone unnoticed because astronomers previously assumed luminous traces of the galaxies in Coma indicated small, insignificant bodies, and not just the most visible central regions of otherwise very dim objects — the tips of galactic icebergs, as it were.

What's more, as Zwicky first wrote in a Swiss journal, galaxies in the Coma cluster seemed to be moving in relation to one another at rates that would violate the laws of gravity, unless you posited the mysterious presence of a great deal of Dunkle Materie (or dark matter).

The supermassive black hole found in NGC 1600 is one of the first successes of the project, proving the value of a systematic search of the night sky rather than looking only in dense areas like those occupied by large clusters of galaxies, such as the Coma and Virgo clusters.

While the black hole discovered in 2011 in the galaxy NGC 4889 in the Coma Cluster was estimated to have an upper limit of 21 billion solar masses, its range of possible masses was large: between 3 billion and 21 billion suns.

After a bunch of galaxies were quenched in a collision with the Coma cluster 7 to 10 billion years ago, why weren't their stars strewn across space?

The high ratio in the Coma cluster galaxies, located about 300 million light - years from Earth, suggests that they were massive enough to rival our own Milky Way but went dormant before they had the chance.

Seven to 10 billion years ago, a bunch of galaxies fell in with a bad crowd at the Coma cluster — a galactic group comprising thousands of their ilk.
