Newly found exoplanet may be suitable for life
... nearly 200 exoplanets have been discovered orbiting similar type stars in the solar neighbourhood. However out of all...is not alone. Two other planets also circle around the same host star; a so-called “hot Earth” that is about 22 percent larger than...

Will Betelgeuse go supernova soon? Probably not say some astronomers
... sky and is one of the largest visible to the naked eye. Its supergiant status already earmarks it as a variable-type star; a star that regularly brightens and dims with generally predictable frequency. In fact it is one of the most variable...

New research shows interstellar visitor 21/Borisov is not your average comet
... that given the abundance of CO to H2O in the comet, 2I/Borisov possibly originated around an M-type star - one of the most common stars in our galaxy. As these types of stellar object have low temperatures and luminosities and form late in their...

Super-Jupiter mass planet found in the galactic bulge
... around which MOA-2016-BLG-227Lb orbits is classed as an M or K-dwarf star – for comparison our Sun is a G type star and is a main sequence yellow dwarf star. Stars are classified by their spectra (the elements that they absorb) and their temperature...

Astronomers find system with six planets
... in 2010 and subsequent observations revealed that the star hosted a quite complex multi-planet system. HD 3445 is a G0V type star. Our Sun for example is a G2V type star (the 0 represents the hottest stars of a given class, so the Sun is cooler than...

Ultra-hot exoplanet literally rains iron say astronomers
...It orbits an inflated F-type star known as WASP-76, an ageing and evolved star around 5.3 billion years old. F stars are between 1.0 to...500 K. Scientists suspect that it is these swollen star properties I.e high temperature and large radii, that give...
