TESS

Double star systems may be hiding masses of potentially habitable Earth-sized planets in their combined glare. Roughly half of all stars are thought to exist in binary systems, in which two massive stellar bodies orbit around a common centre of mass.

A new study has identified 1,004 stars from which aliens could detect signs of life in Earth’s atmosphere by watching as our planet passes across the disk of the Sun. The study could help provide targets for groups searching for alien civilizations.

Astronomers have discovered a new exoplanet that belongs in a brand new class – an “ultrahot Neptune.” Known as LTT 9779b, the planet orbits extremely close to its star, and raises questions about how such a system came to be.

NASA has discovered a strange star system where a gas giant planet is tightly orbiting a tiny white dwarf. This the first sighting of such an arrangement, raising questions about how the planet survived the star’s expansive death in the first place.

NASA's Transiting Exoplanet Survey Satellite space telescope has now wrapped up the primary phase of its mission, completing an extensive survey of the starry sky that revealed 66 new exoplanets and thousands more candidates.

Astronomers have discovered the intact, exposed core of a gas giant locked in a close orbit around a Sun-like star. The discovery will give astronomers a rare opportunity to probe the heart of an ancient alien world.

NASA's TESS telescope has already notched up a few noteworthy achievements. Its latest feat, however, is also its most significant, with the space telescope having now identified its first Earth-sized exoplanet in the habitable zone.

While NASA's TESS satellite was staring off into the depths of interstellar space, the comet 46P/Wirtanen wandered into view. The satellite managed to catch an explosive outburst from the comet in more detail than ever seen before.

NASA has released an enormous mosaic of the southern sky, stitched together from images captured by the agency’s Transiting Exoplanet Survey Satellite (TESS) over the course of its first year of science observations.

The Breakthrough Listen has announced that scientists from NASA's Transiting Exoplanet Survey Satellite (TESS) mission will be working alongside its own researchers as they ramp up the search for intelligent, extraterrestrial life.

NASA's Transiting Exoplanet Survey Satellite (TESS) has observed a gigantic black hole ripping apart a star in a distant galaxy.

NASA’s TESS mission has been very busy lately, making many exoplanet discoveries. Now, the productive little satellite has made another important discovery – the closest super-Earth that’s potentially habitable.
