The First Step in Terraforming Mars

It’s going to be a lot easier to colonize Mars if we can terraform it first. The first step would be to give Mars a thicker atmosphere, which means it will need a magnetic field, or magnetosphere, to protect it. Here’s how we would do that. Continue reading

Collision Of 2 Neutron Stars – Seen For First Time –NPR

The collision of two neutron stars, seen in an artist’s rendering, created both gravitational waves and gamma rays. Researchers used those signals to locate the event with optical telescopes. For the first time, scientists have caught two neutron stars in the act of colliding, revealing that these strange smashups are the source of heavy elements such as gold and platinum. Continue reading
