Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University ...

Astronomers have finally decoded the origin of a powerful seven hour signal from deep space, a blast so persistent that it ...

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 ...

Some stars in our galaxy, known as hypervelocity stars, move much faster than most other stars in the Milky Way. In fact, they are traveling so fast that our galaxy's gravity can't hold onto them and ...

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

The Kuiper Belt object Altjira was thought to be a binary, but closer analysis suggests that it is highly likely to be a triple system This raises the question of the three-body problem; if Altjira ...

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 ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...
