An international team of astronomers has found that the giant radio galaxy (GRG) Mrk 1498 has a more complex nuclear structure than previously thought. By analyzing multi-wavelength observations of Mrk 1498, a young and obscured ...
Our universe is capable of some truly frightening scenarios, and in this case we have an apparent tragedy: two stars, lifelong companions, decide to move away from the Milky Way galaxy together. But after millions of years ...

An international team of astronomers reports the discovery of a new giant protocluster of galaxies. The newly found protocluster was identified at a redshift of 5.7, when the universe was about 1 billion years old. The finding ...
Star formation is one of the most important research fields in astrophysics. This process, in which gravitational instabilities cause the collapse of gas to form more compact structures and finally stars, encompasses a broad ...
