Cosmic Evolution

A new X-ray study has revealed that stars like the Sun and their less massive cousins calm down surprisingly quickly after a turbulent youth.

New work asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of the star’s seven known planets.

An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1.

A team of astronomers has used ESO's Very Large Telescope Interferometer to map Antares's surface.

Astrophysicists have predicted that an Earth-like planet may be lurking in a star system just 16 light years away.

Astrophysicists have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively.

Many exoplanets to be found by coming high-powered telescopes will probably be tidally locked — with one side permanently facing their host star — according to new research.

If we want to know more about whether life could survive on a planet outside our solar system, it’s important to know the age of its star.

Astronomers like to say we are the byproducts of stars--but what about the heavier elements in the periodic chart such as gold, platinum and uranium?

Two separate teams of scientists have identified major challenges for the development of life in what has recently become one of the most famous exoplanet systems, TRAPPIST-1.
