NASA’s latest exoplanet hunting mission is due to launch on April 16th. This mission will look for Earth-like planets closer to home than the previous Kepler exoplanet mission. By looking at stars hundreds or light years away and not thousands, scientists will be able to use ground based telescopes to learn more about these rocky planets.

This extra snow has slightly slowed the effect of global sea level rise.

The team is now looking to see if new human cancer treatments will work in the Tasmanian Devil population, so far the lab tests are promising.
