New hard X-ray eclipsing polar identified

Using ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have found that a hard X-ray source known as 2PBCJ0658.0-1746 is an eclipsing magnetic cataclysmic variable of the polar type. The finding, presented in a paper ...

Ultra-short period brown dwarf discovered

An international team of astronomers has detected a new brown dwarf with an ultra-short orbital period that transits an active M-dwarf star. The newfound object, designated NGTS-7Ab, turns out to be the shortest period transiting ...

The low density of some exoplanets is confirmed

The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity whenever an orbiting planet moved across the face of ...

Exomoons may be home to extra-terrestrial life

Moons orbiting planets outside our solar system could offer another clue about the pool of worlds that may be home to extra-terrestrial life, according to an astrophysicist at the University of Lincoln.

An exoplanet with an 11-hour orbit

The Transiting Exoplanet Survey Satellite (TESS) was launched on April 18 of last year with the primary objective of discovering transiting planets smaller than Neptune around stars bright enough for spectroscopic investigations ...

A new, potentially inhabitable super-Earth

Researchers at the University of Oviedo, in collaboration with the Instituto de Astrofísica de Canarias (IAC) have discovered and characterized a planet in the habitability zone of a red dwarf star. It was detected using ...
