Obscured supermassive black holes in galaxies

Most if not all galaxies are thought to host a supermassive black hole in their nuclei. It grows by accreting mass, and while feeding it is not hidden from our view: it generates X-ray emission and ultraviolet that heats ...

Study inspects galaxy protocluster PHz G237.01+42.50

An international team of astronomers has performed spectroscopic observations of a distant galaxy protocluster known as PHz G237.01+42.50. Results of the study, presented in a paper published September 9 on the arXiv pre-print ...

Techniques to prove or disprove existence of other planets

Astronomers long have sought to find planets that can sustain life as humans know it. Four years ago, they thought they had one, possibly even two, pointing to signs that suggested that at least one rocky planet located in ...

Star formation near supermassive black holes

Most if not all galaxies are thought to host a supermassive black hole in their nuclei, a finding that is both one the most important and amazing in modern astronomy. A supermassive black hole grows by accreting mass, and ...

Watching solar activity muddle Earth's magnetic field

(PhysOrg.com) -- Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes affect ...
