Although mass is the most important property of stars, it has proved very hard to measure for the lowest mass objects in the universe. Thanks to a powerful new camera, a very rare, low-mass companion ...
A team of astronomers have found a mysterious object in the distant universe that could be dark matter or an inactive smaller, or dwarf, galaxy.
In a distant stretch of the universe, more than 10 billion light-years from Earth, astronomers have discovered something ...
Astronomers have recently uncovered a colossal dark object outside our Solar System that defies direct observation. This ...
A research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational ...
Two new studies, based on observations made with ESO’s telescopes, show that objects only a few times more massive than Jupiter are born with discs of dust and gas, the raw material for planet making.
The abundance of low-mass compact objects, at or below the hydrogen-burning mass limit of 0.08M ⊙ (where M ⊙ is the solar mass), remains an open question. This abundance has implications for such ...
