The speed and distance at which planets orbit their respective blazing stars can determine each planet's fate—whether the planet remains a longstanding part of its solar system or evaporates into the universe's dark graveyard ...
Astronomers have discovered a distant planet with an abundance of helium in its atmosphere, which has swollen to resemble an inflated balloon.
A new study led by scientists from the Instituto de Astrofísica de Canarias (IAC) reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field and ...
An international team of astronomers using a combination of ground and space-based telescopes have reported more than 100 extrasolar planets in only three months. These planets are quite diverse and are expected to play a ...
The Characterising Exoplanet Satellite, Cheops, will target 15 October to 14 November 2019 for launch.
They say there's more than one way to skin an interstellar cat, and in astronomy there's more than one way to find alien exoplanets orbiting a distant star. With the recent shut-down of NASA's prolific Kepler mission and ...
In the past 30 years, the number of planets discovered beyond our solar system has grown exponentially. Unfortunately, due to the limitations of our technology, the vast majority of these exoplanets have been discovered by ...
An international team led by the astrophysicist Carolina von Essen, has used the OSIRIS spectrograph on the Gran Telescopio Canarias (GTC) to study the chemical composition of a planet whose equilibrium temperature is around ...
The Kepler spacecraft launched in 2009 with the goal of finding exoplanets orbiting distant stars. In the years since, astronomers have used Kepler observations to discover 2,818 exoplanets as well as another 2,679 exoplanet ...
