Astronomers studying data from NASA’s TESS mission have found a remarkable sextuple star system featuring three gravitationally bound eclipsing binaries.
The system around HD 158259 star consists of an innermost large rocky planet (a “super-Earth”) and five small gas giants (“mini-Neptunes”) that have exceptionally regular spacing between them.
Scientists identified the cause of the unusual single-sided pulsation of the star named HD 74423. It is located in a binary star system with a red dwarf - its close companion distorts the oscillations with its gravitational pull.
The habitable-zone planet is one of three orbiting a star known as TOI 700, a cool M dwarf located about 100 light-years from Earth. The candidate planet, TOI 700 d, is is at a distance where temperatures would allow water to exist in liquid form.
The exoplanet is orbiting a small star 35 light years from Earth and is about 80 percent the size of Earth. It orbits its host sun, an M dwarf known as L 98-59, every 2.25 days.
The three confirmed planets discovered so far using TESS are all within 100 light-years of our solar system, substantially closer than the nearly 2,700 validated worlds detected using Kepler.
NASA's TESS, made an early discovery of "super-Earth" and "hot Earth" planets in solar systems at least 49 light-years away, marking the satellite's first discovery since its April launch.
NASA’s newest exoplanet-hunting spacecraft has started taking scientific data as of last week, according to a NASA release.
Scientists have analyzed data from K2, the follow-up mission to NASA's Kepler Space Telescope, and have discovered a trove of possible exoplanets amid some 50,000 stars.
Transiting Exoplanet Survey Satellite – TESS – has snapped a stunning test photo showing an estimated 200,000 stars cantered on the southern constellation Centaurus.
