In a study of the Earth’s mantle, scientists have identified two compositionally distinct continent-sized anomalies which could be traces of a protoplanet which impacted with Earth during its early formation.

Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.

66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs.

The further we move away from a heat source, the cooler the air gets. Bizarrely, the same can’t be said for the Sun, but University of Otago scientists may have just explained a key part of why.

Researchers from the University of Turku, Finland, found that the axis of rotation of a black hole in a binary system is tilted more than 40 degrees relative to the axis of stellar orbit. The finding challenges current theoretical models of black hole formation.

In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward.
