Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...

Stars are born in clouds of gas and dust, making it difficult to observe their early development. But researchers at Chalmers have now succeeded in simulating how a star with the mass of the sun ...

A new study from scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) suggests that previously displaced gases can re-accrete onto galaxies, potentially slowing down the process of ...

Black hole accretion processes remain at the forefront of astrophysical research, offering critical insights into how matter is captured by these extreme objects. Accretion occurs when gas, dust, and ...

Scientists have leveraged data gathered using the Atacama Large Millimeter/submillimeter Array (ALMA) in a new study. The information gathered suggests that previously displaced gases can re-accrete ...

A distant neutron star unexpectedly reawakened, unleashing a powerful X-ray surge that may reveal how the universe’s most extreme stars feed.

When gas falls onto a compact object, such as a neutron star or black hole, due to its strong gravity (a process called accretion), it emits electromagnetic waves. High-sensitivity observations have ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star ...

Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, ...

Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that’s between that of Neptune and Saturn, and its location beyond the “snow line” of its ...

A new study suggests that previously displaced gases can re-accrete onto galaxies, potentially slowing down the process of galaxy death caused by ram pressure stripping, and creating unique structures ...
