When Oscar Wilde said “conversation about the weather is the last refuge of the unimaginative” he was unaware of some of the more extreme weather on planets and moons other than Earth. Since the discovery of the first exoplanet in 1992, more than 4,000 planets...

A team of astronomers from the Grenoble Alpes University in France and elsewhere, reports the detection of a new sub-Neptune exoplanet orbiting an M dwarf star. The newly found alien world, designated TOI-269 b, is nearly three times larger than the Earth. The finding was...

Earth-sized world discovered in nearby α Centauri star system. It is a world so close that E.T. could phone home in just four years. Astronomers have discovered the lowest-mass planet yet orbiting a Sun-like star. It orbits α Centauri B, a member of the stellar...

A pioneering European space telescope that discovered the first rocky extrasolar planet is on its last legs, Nature has learned. According to the French space agency CNES, the Convection, Rotation and Planetary Transits (CoRoT) satellite suffered a computer failure on 2 November. Although the spacecraft...

The newly detected world is smaller than any of the solar system’s planets and just a bit larger than our moon. An article by Scientific American. A newfound world called Kepler 37 b could easily blend in to the long and growing list of known...

Gaseous planet challenges assumption that Earth-mass planets should be rocky. Astronomers have discovered an extrasolar planet with the same mass as Earth, but the resemblance ends there. Not only is the planet too warm for liquid water to exist on its surface, but it also...

Findings from the now-disabled Kepler probe have been validated, quadrupling its booty of extrasolar worlds. Astronomers announced today that 715 exoplanet candidates found by NASA’s Kepler spacecraft have been confirmed as planets. The bonanza nearly quadruples the number of already confirmed alien worlds found by...

Using the radial velocity (RV) technique, astronomers have discovered a new super-Earth alien world as part of the HADES and CARMENES programs. The newfound exoplanet, designated GJ 740 b, orbits a bright star some 36 light-years away and is at least three times more massive...

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an interesting extrasolar planetary system consisting of a K-dwarf host star, a Jupiter-sized planet and a white dwarf. The finding and parameters of the system, designated TOI-1259, were presented in a...

Orbiting a red dwarf star 41 light-years away is an Earth-sized, rocky exoplanet called GJ 1132 b. In some ways, GJ 1132 b has intriguing parallels to Earth, but in other ways it is very different. One of the differences is that its smoggy, hazy...
