Galaxies are some of themost distant objects we can observe. While most planets, stars, and nebulae are usually pretty nearby to us, we can observe galaxies that are millions of light-years away. ... Even if a galaxy is bright, the most you might typically see is its core with a 4-...
Galaxies are giant structures made of dust, gas, stars and other celestial bodies spread through an immense area of space. Our own galaxy, the Milky Way, consists of more than a hundred billion stars strung across tens of thousands of light years. Galaxies are broken down into three basic s...

What are the two types of radio galaxies? There are two distinct types of radio galaxies defined by differences in their optical emissions. Broad-line radio galaxies show broad-line light emissions from ionized oxygen, hydrogen, and silicon in their optical spectrum. Narrow-line radio galaxies are...
Among early-type galaxies with almost circular isophotes, E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0(0) and S(0)(1). This result supports the view that rotation and "diskiness" are more important in the outer regions of faint early...
What is the true shape of the universe? A flat universe has Euclidean geometry, and the simplest shape it can adopt is that of a sheet. There are also other, more complex shapes that a flat universe could have, such as a "3-torus." How to measure the shape of the universe The ge...
Springtime is notably galaxy season, but if you don't like faint fuzzies, you won't think much of it. The Cigar and Bode Galaxies are interesting shapes and quite close together. Pretty easy to see as well. M81 and m82. And Whirlpool Galaxy you should be able to see the two parts ...
This dataset is unique as for the morphological information on faint high-z sources, and for complete photometric and spectroscopic coverage. The majority of bright early-type galaxies in this field are found at redshifts $z \\leq 1.3$ to share common properties with those of high-z cluster...
Blue Supergiant Stars: Behemoths of the Galaxies There are many different types of stars that astronomers study. Some live long and prosper while others are born on the fast track. Those live relatively short stellar lives and die explosive deaths after only a few tens of millions of years. ...
