Discovery of 2 exoplanets orbiting very cold star LP 890-9

Astronomers discovered 2 new exoplanets orbiting a very cold star LP 890-9. One of the exoplanets seems to be in the habitable zone of the star, and therefore is a very interesting target for future observations. The star LP 890-9 is currently the second coldest star with known exoplanets.

Gaia space telescope discovered its first two exoplanets

European space observatory Gaia measures precise positions of stars in our galaxy, however it can also look for exoplanets. Scientists now report confirmation of two exoplanets discovered by the spacecraft.

Three Jupiter-sized exoplanets discovered oribiting sun-like stars

Astronomers confirmed the existence of three exoplanets TOI-1820 b, TOI-2025 b, and TOI-2158 b. Their method also uncovered their masses, which gives scientists a better idea about their density and structure. All three are similar in size to Jupiter and orbit their stars on very tight orbits.

Astronomers discovered 3 additional exoplanet orbiting nearby star TOI 500

Star TOI 500 is located 155 light years from the Solar system. There was already a known exoplanet orbiting it, now there are 3 more. The system now consists of 2 very close exoplanets and two more bit further (all of them are still closer to their star than Earth to Sun).

Two rocky exoplanets discovered orbiting nearby star Gliese 239

Star Gliese 239 lies 33 light years away. It is a red dwarf with half the mass and size of the Sun. Astronomers now report discovery of two transiting exoplanets, both bigger than the Earth but still rocky. They orbit very close to their star and have high temperatures on their surfaces.

New warm super-Neptune discovered orbiting Sun-like star TOI 1710

Astronomers discovered a new exoplanet 265 light years away from the Sun. It orbits a yellow Sun-like star in a tight orbit, much closer than planet Mercury orbits the Sun. The exoplanet TOI 1710 b is 28 times heavier than Earth (planet Neptune is 17 times heavier than our planet). Astronomers label it a warm super-Neptune. It is a great candidate for study of the atmospheres of warm Neptunes and their evolution.
