One of the most noteworthy features of elliptical galaxies is they have a very low number of open clusters (a group of few thousand stars) and a low rate of star formation. These galaxies generally consist of older, more evolved stars. The largest galaxies in the observable universe are elli...
Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that they’re much cooler than stars like our Sun. They have another advantage. Red dwarf stars are able to keep the hydrogen fuel mixing into their core, and s...
Based on lambda cold dark matter model star clusters were studied at different epochs of the universe.Gadget-2 code was used for simulating the stars at different epochs of the universe.In the simulation it was found that; the first star born in the low redshift z=4.019 while in the ...
As far as astronomers can determine, the entire universe is built of the same matter. (26) They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same...

When discussing objects in space, it is correct to think of the Universe as a collection of millions of different galaxies. Galaxies are large groupings of gas, stars, space dust, planets, and other celestial objects, held together by the strong gravitational attraction between them. How many ...
These stars were not the first stars to form in the universe (those would have been composed of hydrogen and helium only) but were still members of a very early generation of stars. The Epoch of Reionization wasn't an instantaneous event, so while the new results are not enough to close...
At the center of spiral galaxies, you'll find a cluster of very old stars revolving around a central point. This is the bulge. While the stars out in the disc move around in an orderly, horizontal plane, the stars that comprise the bulge act like bees erratically swarming around a hive...
