Exoplanet orbiting nearby star Gliese 486 could be a perfect candidate for atmosphere study

19. 05 2021 Astronomers identified new exoplanet around a star 26 light years away. Usually new exoplanets are found with a transit method or with radial velocity. In this case, the planet was observed via both methods, which gave astronomers information about both mass and size. - 10056




Biggest stellar-mass black hole in Milky Way is a mystery, scientists don't know how it was created

29. 11 2019 Chinese scientists discovered new candidate for a stellar-mass black hole that defies current models of black hole creation. The black hole designated LB-1 has 68 solar masses and is orbited by young massive star on a circular orbit. - 10759


Newly discovered exoplanet TOI-677b is a new addition to a Warm Jupiter category

21. 11 2019 Warm Jupiters are exoplanets that resemble our own Jupiter with their mass, but orbit their mother stars much closer. Not as close as Hot Jupiters, that have orbital period lower than 10 days, year on warm Jupiters lasts between 10 and 100 days. - 10056


Observations with Spitzer telescope show there is likely no atmosphere on nearby exoplanet LHS 3844b

12. 11 2019 Exoplanet LHS 3844b was discovered in 2018 by space telescope TESS in distance of 49 light-years. Follow-up observations with infrared telescope Spitzer show, that there is likely no atmosphere present due to the proximity to its star LHS 3844. -


For the first time, movements of gases in 3 dimensions observed in disk around a newborn star

05. 11 2019 According to a study in Nature magazine, the movements of CO gas in a protoplanetary disc around young star HD 163296 might be caused by newborn exoplanets. Other causes are possible, like the magnetism of the star itself, but exoplanets are the lead explanation so far. - 10584


Astronomers discovered the lightest black hole so far - it weighs only 3,3 solar masses

01. 11 2019 Black holes are not easy to spot, their gravity absorbs any light that gets close to them. But there is a way - if a black hole is a part of binary star, it affects the movement of its companion. This is what astronomers spotted happening to star 2MASS J05215658+4359220 - something orbits it every 83 days. And that something is weighing only 3,3 solar masses - if it is a black hole, it's the least massive known to date. - 10682


Newly confirmed exoplanet makes star Groombridge 34 one of the closest multiplanetary star systems

18. 10 2019 In October NASA published 16 new exoplanets in its Exoplanet Archive, among them also planets b and c orbiting red dwarf Groombridge 34 A (Gliese 15 A). In distance of a little more than 11 light years it is now the closest multiplanetary system to the Sun. -



Massive exoplanet surprised astronomers: it's too big for its mother star

30. 09 2019 Astronomers found a new exoplanet in a nearby red dwarf system. Even though the exoplanet is smaller than Jupiter, considering the size of its star it's huge. Scientists even consider how it could be possible for a planet like this to evolve around star like that. -


Water vapor discovered in the atmosphere of the exoplanet K2-18b

11. 09 2019 Exoplanet K2-18b, discovered in 2015 with Kepler telescope, is twice as big as Earth - but 9 times more massive. It orbits its star in habitable zone and apparently has water in its atmosphere. It is the smallest exoplanet with detected water vapor in the habitable zone of a star. - 10346
