This is the first-ever image of an alien multi-planet system

July 22nd, 2020

Researchers at the European Southern Observatory have captured the first-ever images of a planetary system with multiple exoplanets. The system revolves around a star that is a lot like our sun, only younger. Observing these alien systems will teach scientists how systems like our own formed and evolved over time. The technology of detecting exoplanets …

Volcanos still rule the surface of Venus

July 20th, 2020

The surface of Venus is covered in coronae that are still active today. Vast fields of lava may regularly erupt, spewing liquid rock over vast areas. Previous models of Venus suggested it was far less active and had mostly cooled. Earth is in a sweet spot when it comes to volcanic activity. We have enough …

Should we create our own alien life in outer space?

July 16th, 2020

NASA is doing everything it can to avoid bringing Earthly organisms to other worlds, but what if we should be doing the opposite? Seeding other worlds with life could potentially have big benefits for humanity in the distant future. Icy moons like Enceladus may already host alien life. If you’ve never seen the movie Prometheus — the …
