Gravitational waves could show what?s happening inside a star as it?s going supernova

   08 Sep 00:00:23  |  Universe Today

It’s kind of hard to see inside a star as it’s blowing up, because of the whole “blowing up” part, but gravitational waves – tiny ripples in the fabric of spacetime itself – may help astronomers unlock how the biggest stars die. It takes a lot of raw energy to power a supernova. When the …

The Solar System has been Flying Through the Debris of a Supernova for 33,000 Years

   06 Sep 00:00:28  |  Universe Today

An Ancient Voyage Earth is on a journey? While our planet orbits the Sun each year – a billion kilometers – our entire Solar System is drifting through the Milky Way Galaxy making one rotation every 225-250 million years (that means dinosaurs actually lived on the other side of the Galaxy!) Humanity has been on …

Neptune & Triton ? August 31, 1989.

   05 Sep 00:00:07  |  Universe Today

Image-processor extraordinaire Kevin Gill has reached back in time to give us a new image of Neptune and its moon Triton. When NASA’s Voyager 2 spacecraft flew past Neptune and Triton in August 1989, its cameras were very busy. Kevin has taken separate color-filtered images from that visit and calibrated and combined them to give …
