This illustration of the newly forming exoplanet PDS 70b shows how material may be falling onto the giant world as it builds up mass. By employing Hubble’s ultraviolet light (UV) sensitivity, researchers got a unique look at radiation from extremely hot gas falling onto the planet, allowing them to directly […]

This exoplanet, a gas giant called GJ 504b, is about 57 light-years away from Earth. Exoplanets like this may help researchers find and measure dark matter.

NASA’s Galileo spacecraft caught Jupiter’s moon Io, the planet’s third-largest moon, undergoing a volcanic eruption. Locked in a perpetual tug of war between the imposing gravity of Jupiter and the smaller, consistent pulls of its neighboring moons, Io’s distorted orbit causes it to flex as it swoops around the gas […]

This illustration captures an exoplanet as it is about to cross in front of – or transit – its star.

Vega is the fifth brightest star, excluding the sun, that can be seen from Earth. Credit: Stephen Rahn Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky. The research, published this month in The Astronomical Journal, was led by University […]

An international research team with members from ETH has developed a new method for directly imaging smaller planets in the habitable zone of a neighboring star system. This opens up new possibilities in the search for extraterrestrial life. In the search for planets capable of sustaining life, an international research […]

Also, using a combination of different observing techniques […]
