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...

However most of the events we have found are blue and are either still rising or decaying slowly, on a timescale of years; the few spectra we have show AGN at z ∼ 1. We argue that these transients are background AGN microlensed by stars in foreground galaxies by a factor 10–100....
are massive enough to effectively counter the escape velocity of the ejected material. But elliptical galaxies are a different story. They not only lack this halo of material but they are generally less massive than other galaxy types. The ejected material would act like a galactic wind, ...

This year, the brilliant planet Jupiter will be shining about 1.3 fist diameters to the lower left (or 13 degrees to the celestial east) of the cluster. The “sisters” are medium-bright, hot blue stars named Asterope, Merope, Electra, Maia, Taygeta, Celaeno, and Alcyone. In Greek ...
Nebulas, or vast clouds of gas that often condense to become new stars, also have impressively large sizes. NGC 604 in the Triangulum Galaxy is commonly cited as one of the largest; it's roughly 1,520 light-years across. Galaxies are collections of star systems and everything inside those...
