Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about ...

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 ...

Astronomers using the Very Large Telescope study faint brown dwarfs in the RCW 36 nebula to understand substellar populations and the initial mass function in a young massive cluster.

An international team of astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have spotted a rogue planet breaking a new record; growing at a rate of 6 billion tonnes ...

An object spotted with help of citizen scientists was moving so fast through the Milky Way that it could escape the gravity of the galaxy and reach intergalactic space, new research has found. Likely ...

Using NASA’s Swift and Rossi X-ray Timing Explorer (RXTE) satellites, astronomers have discovered one of the most bizarre planet-mass objects ever found. The object’s minimum mass is only about 7 ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

Using a worldwide network of radio telescopes including the Green Bank Telescope in West Virginia, astronomers have discovered a mysterious object in the distant universe. A million times the mass of ...
