A fast-moving star may have been ejected from the Milky Way's stellar disk by a cluster of young stars, according to researchers from the University of Michigan who say the star did not originate from the middle of the galaxy, ...

The Milky Way galaxy's disk of stars is anything but stable and flat. Instead, it becomes increasingly warped and twisted far away from the Milky Way's center, according to astronomers from National Astronomical Observatories ...

Astronomers use stellar eclipses to study the atmosphere of accretion disks around compact stars. SRON-researchers observed this method on a low-mass X-ray binary. They find a thicker atmosphere than predicted and distinguish ...

(Phys.org)—Andromeda IV, discovered in 1972 by Canadian astronomer Sidney Van den Berghan, is believed to be an irregular satellite of our neighboring Andromeda galaxy, also known as Messier 31. Now, a new study conducted ...
(Phys.org)—Many black holes are believed to have surrounding accretion disks of matter trapped by gravity and spiraling toward the event horizon. Supercritical accretion disks (SCADs) are those with mass accretion rates ...
A detailed study of the motions of different stellar populations in the disk of the Andromeda galaxy has found striking differences from our own Milky Way, suggesting a more violent history of mergers with smaller galaxies ...

(Phys.org) -- New research, led by University of Warwick physicist Dr Kareem Osman, has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards from the raging inferno ...

Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometres, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact matter on the Earth would ...

(PhysOrg.com) -- Astronomers once thought that the process of star formation was more-or-less controlled by the simple coalescence of material by gravity, leading eventually to a new star. But they have come to realize that ...
