The exploration of binary star systems reveals surprises that challenge our conceptions of planetary formation. Thanks to NASA's TESS satellite, specialized in hunting exoplanets, an ...

An international team of astronomers has confirmed the discovery of three Earth-sized planets in the binary star system ...

Microquasars in our Milky Way galaxy have emerged as the most extreme particle engines, accelerating cosmic rays to ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why ...

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 ...

Star formation is an intricate process that transforms vast molecular clouds into newborn stars, often accompanied by the formation of circumstellar discs composed of gas and dust. These ...

From a zoomed out, distant view, star-forming cloud L483 appears normal. But when a Northwestern University-led team of astrophysicists zoomed in closer and closer, things became weirder and weirder.
