Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star's death, says a new study led by the University of Warwick that reveals the consequences of the intense and furious stellar winds that will batter a planet as its star is dying.
These motions were measured by analyzing 10 years of observations from NASA's Solar Dynamics Observatory.
New research indicates that if neutron stars have mountains, they are fractions of a millimeter in height.
The final stage of cataclysmic explosions of dying massive stars, called supernovae, could pack an up to six times bigger punch on the surrounding interstellar gas with the help of cosmic rays, according to a new study led by researchers at the University of Oxford.
An international team anchored by the Event Horizon Telescope Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearby radio galaxy Centaurus A in unprecedented detail.
A team of astronomers has released new observations of nearby galaxies that resemble colourful cosmic fireworks.
An international research team led by YAO Zhonghua from the Institute of Geology and Geophysics of the Chinese Academy of Sciences has explained the cause of Jupiter's X-ray aurorae, a mystery that has puzzled scientists for 40 years.
New models of neutron stars show that their tallest mountains may be only fractions of millimetres high, due to the huge gravity on the ultra-dense objects. The research is presented today at the National Astronomy Meeting 2021.
Dr. Iair Arcavi, a Tel Aviv University researcher at the Raymond and Beverly Sackler Faculty of Exact Sciences, participated in a study that discovered a new type of stellar explosion - an electron-capture supernova.
Black holes are found at the centre of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light.
