Evidence For White Dwarfs Consuming Earth-Like Worlds

Finding other Earth-like planets in our Milky Way galaxy has been a holy grail of exoplanet research. Astronomers have found Earth-sized exoplanets. But is an Earth-sized planet going to be Earth-like? We still don’t know. Now, though, scientists at the University of Warwick in the...

Bizarre Weather On Other Worlds: 4 Examples

This comic-book-style illustration by Swiss graphic novelist Frederik Peeters shows a closeup view of the evening border of the exoplanet WASP-76b. The ultra-hot giant exoplanet has a day side where temperatures climb above 2,400 degrees Celsius (4,000 degrees F), high enough to vaporize metals. Strong...

Wet exoplanet has clear skies

The smallest exoplanet yet found to contain water is about the size of Neptune — and a rare glimpse at its atmosphere reveals clear conditions. The smallest exoplanet yet found to contain water is about the size of Neptune — and a rare glimpse at...

A gaze at exoplanet haze

Spectroscopic observations of a distant planet swooping across the face of its sun have given astronomers a first-ever look at the atmosphere of an Earth-like planet lying beyond our Solar System. The new data don’t provide a precise list of gaseous constituents, but they do...

How the habitability of exoplanets is influenced by their rocks

The weathering of silicate rocks plays an important role to keep the climate on Earth clement. Scientists led by the University of Bern and the Swiss national center of competence in research (NCCR) PlanetS, investigated the general principles of this process. Their results could influence...

Habitable exoplanets are bad news for humanity

Last week, scientists announced the discovery of Kepler-186f, a planet 492 light years away in the Cygnus constellation. Kepler-186f is special because it marks the first planet almost exactly the same size as Earth orbiting in the “habitable zone” – the distance from a star...
