Sporadic Radio Pulses Traced to White Dwarf-Red-Dwarf Binary System
Astrophysicists have found that a recently-discovered transient radio source, ILT J110160.52+552119.62, whose roughly minute-long pulses arrive with a periodicity of 125.5 min, is an red dwarf-white dwarf binary system with an orbital period…

Entwined dwarf stars reveal their location thanks to repeated radio bursts
An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio pulses.
Thanks to follow-up observations…

Astronomers Find Evidence for Four Sub-Earth Exoplanets around Barnard’s Star
For a century, astronomers have been studying Barnard’s star in the hope of finding planets around it. First discovered by E.E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth. Now, astronomers using the

Four tiny planets found orbiting one of our nearest stars
Astronomers have revealed new evidence that there are not just one but four tiny planets circling around Barnard’s Star, the second-nearest star system to Earth.
The four planets, each only about 20 to 30% the mass of Earth, are so close to their…

Super-Earths and mini-Neptunes: More Earth-like planets may exist
A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation of super-Earths and mini-Neptunes — planets that are 1 to 4 times the size of Earth and among the most common in our…

Small, faint and ‘unexpected in a lot of different ways’: Astronomers make galactic discovery
A discovery made by a team led by researchers at the University of Michigan tugs at the seams of some key cosmic lessons we thought we had learned from our own galaxy.
This new knowledge comes from the outskirts of Andromeda, the Milky Way’s…
