SEATTLE–After three years of observations using the 10-meter Keck II telescope in Hawaii, Lowell Observatory astronomer Lisa Prato announces discovery of four new low-mass double star systems with ...

Context. The CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be used to measure ...

Astronomers have discovered evidence that orbiting Starlink satellites can contaminate their observations and appear as binary stars. Earlier this month, a group of astronomers published a preprint ...

Astronomers have confirmed a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed ...

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

Time-lapse footage of a newly discovered exoplanet as it makes its slow journey around two stars. To obtain the image of the planet, astronomers needed to remove the stars' glare. Two star icons mark ...
