The Birth of a Black Hole Not as Boring as Thought

  A new kind of cosmic flash may reveal something never seen before: the birth of a black hole.   When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a new [continue reading]

The Sun's Shockwaves Formed the Planets at Different Times

  The early years of our Solar System were a turbulent time, and questions remain about its development. Dr Tagir Abdylmyanov, Associate Professor from Kazan State Power Engineering University, has been researching shockwaves emitted from our very young Sun, and has discovered that these would have caused the planets in our Solar System to form [continue reading]

 The Van Allen Radiation Belts to be Examined

  A University of Minnesota-led experiment is aboard NASA’s Radiation Belt Storm Probes (RBSP) mission, a probe of the forces that govern radiation in the Van Allen Radiation Belts. These two concentric, doughnut-shaped regions of space girdle the Earth and pose radiation danger to astronauts and spacecraft. The twin RBSP satellites and the Van Allen [continue reading]

A Wrinkle in Space-Time

  Mathematicians at UC Davis have come up with a new way to crinkle up the fabric of space-time — at least in theory. Illustration of twisted space-time around Earth. Image Credit: NASA “We show that space-time cannot be locally flat at a point where two shock waves collide,” said Blake Temple, professor of mathematics [continue reading]

Supernova Explosions Polluted the Solar System

  For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. According to this theory, the shock wave also injected material from the exploding star into a cloud of dust and gas, and the newly polluted cloud collapsed to form the Sun and its [continue reading]
