Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

A fresh analysis of gravitational wave data from a 2020 collision between a black hole and a neutron star has produced the first measured evidence of an eccentric, oval-shaped orbit in this type of ...

How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...

The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view. However, Cheng and colleagues observe ...

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...
