A Dip Into Space
Messier 64 or The Black Eye Galaxy
Easily identified by the spectacular band of absorbing dust partially obscuring its bright nucleus, M64 is characterized by its bizarre internal motion. The gas in the outer regions of this remarkable galaxy is rotating in the opposite direction from the gas and stars in its inner regions. This strange behavior can be attributed to a merger between M64 and a satellite galaxy over a billion years ago
.
I loved this one so much I included more info than I normally do.
The Dead Disk Galaxy
The first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.
Finding such a galaxy early in the history of the universe challenges the current understanding of how massive galaxies form and evolve, say researchers.
When Hubble photographed the galaxy, astronomers expected to see a chaotic ball of stars formed through galaxies merging together. Instead, they saw evidence that the stars were born in a pancake-shaped disk.
This is the first direct observational evidence that at least some of the earliest so-called "dead" galaxies — where star formation stopped — somehow evolve from a Milky Way-shaped disk into the giant elliptical galaxies we see today.
This is a surprise because elliptical galaxies contain older stars, while spiral galaxies typically contain younger blue stars. At least some of these early "dead" disk galaxies must have gone through major makeovers. They not only changed their structure, but also the motions of their stars to make a shape of an elliptical galaxy.
“The Dreamer awakes
The shadow goes by
The tale I have told you,
That tale is a lie.
But listen to me,
Bright maiden, proud youth
The tale is a lie;
What it tells is the truth.â€
