Record-Breaking Laser Experiment Could Teach Us About the Cores of Super-Earths

An enormous laser targeted for shutdown by proposed federal budget cuts has just done some record-breaking science in order to understand the centres of faraway exoplanets that scientists call “super-Earths.” Read More >>

Intense Gravity of Super-Earths Could Trap Aliens on Their Home Planet

Rocky worlds larger than Earth are commonplace in the galaxy, and a few of them may even be habitable. Which poses an interesting question: How difficult would it be for aliens living on these super-Earths to launch rockets into space, given the tremendous gravity? According to new research, it would be difficult to the point of impossibility—meaning that some aliens may be perpetually trapped on their home worlds. Read More >>

This Is the Smallest Exoplanet Known to Have an Atmosphere

Using a ground-based telescope, an international team of astronomers has detected traces of an atmosphere around an exoplanet located 39 light-years away. This exoplanet is not much larger than our own, making it the most Earth-like planet known to harbour an atmosphere. Read More >>

Could There Be Massive Planets in the Far Reaches of Our Solar System?

A pair of new studies claim to have discovered two of the most distant objects ever seen in the outer reaches of the Solar System, including a “Super Earth” located six times further away than Pluto. It’s an extraordinary claim — and it’s also highly unlikely. Read More >>
