Starquakes

By using data from almost two billion stars,provided by the space observatory, Gaia, astrophysicists have discovered that stars experience earth-like quakes. The phenomena are known as non-radial oscillations and act like tsunami movements on a star’s crust, causing the star to change its shape. Gai...

Nasa’s CubeSat to the Moon

Yesterday, NASA launched a CubeSat to the Moon that’s no bigger than a microwave oven. The launch was from New Zealand. The aim of the launch is an experiment to find a suitable orbit for astronaut moon landings. If the experiment is a success, the Capstone CubeSat will be the first to take the new ...
