NASA announces the discovery of first-ever exoplanet system with seven Earth-size planets
... to say if any of the planets were able to retain their atmospheres – as ultra-cool dwarf stars are known to be very active when young, the star's activity could have eroded the atmospheres at some point in the past. However, the...

Making a cosmic impression
.... This brought me to study condensed matter, and how we could find new white dwarf stars. In the process, I discovered seven new white dwarf stars using a 48-inch Ritchie-Chrétien reflector at the Elginfield Observatory at the University of Western...

Astronomers discover more than 350 possible new exoplanets
... already known about, such as EPIC 211428897, a multi-planet system consisting of four Earth-sized planets orbiting an M dwarf star. First spotted in 2017, only three planets were initially discovered in the system but subsequent studies have...

Earth-sized planet found around our nearest neighbouring star
... presence of a planet with a mass at least 1.3 times that of the Earth, orbiting about 7 million kilometres from the dwarf star. In comparison, the average distance between the Earth and the Sun is 149.60 million kilometres (92.96 million miles...

Harmful stellar flares might not prevent life on exoplanets after all, new study says
...doom and gloom. After an extensive study of planets orbiting within the habitable zones of M and K dwarf stars – the most common stars in the universe – a team of researchers used a combination of 3D atmospheric chemistry and climate modelling to see...
