An astronomer has proposed a method for deflecting asteroids away from Earth with missiles to stop the next mass extinction.
Astrophysical Masers, Megamasers, and their important role in astronomy
Masers are an example of how naturally occurring phenomena could create coherent and amplified radiation making them useful in astronomy
VIDEO: Head on star collision
A simulation of a head on star collision. Both stars have disks of minor planets. This simulation shows how such events could affect them.
Gravitomagnetism: We may not need dark matter after all
Dark matter may not exist. Instead a phenomenon predicted known as Gravitomagnetism could explain the high rotation curves of galaxies.
VIDEO: 6 planet system formation
A simulation of a 6 planet system forming. The simulation starts of with 900 objects and tracks how they merge into the final planets.
Population III stars blast imprints in the cosmic microwave background
Astrophysicists count the number of mysterious population III stars by observing the imprints they leave in the cosmic microwave background.
Gravitational waves turn dark matter into black holes as the universe dies
Physicists found that dark matter halos will eventually collapse into black holes as they leak energy through to gravitational waves.
WD 1856: A star that engulfed it’s two planets and destroyed one
Astronomers have discovered a planet that survived being engulfed by it’s star and influenced it’s evolution during it’s red giant phase.
Black hole gruesomely rips apart star in another galaxy
Astronomers have detected a radio emission in another galaxy from an accretion disk caused by a black hole tearing apart a star.
