Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

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 ...

What happens when a planet defies every expectation of how worlds are supposed to form and move? In the nu Octantis system, astronomers have confirmed the existence of a planet that orbits in the ...

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 ...

Astronomers recently released a new image of the binary star system Eta Carinae's full spectrum, taken from deep in Chile's Atacama Desert. The image was captured with the newly installed SOAR ...

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 ...

"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of black hole binaries." ...

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 ...

In the most extensive ultraviolet study of blue stragglers ever performed, an international research team used NASA's and ESA ...
