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 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 ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

A rare interstellar visitor, comet 3I/ATLAS, is currently traversing our solar system, offering scientists a unique chance to ...

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 ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

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 ...

A newly discovered interstellar comet is puzzling astronomers as it speeds through our solar system with a chemical profile unlike anything seen before. Officially named 3I/ATLAS, it's only the third ...

Astronomers have for the first time spotted a solar system beyond our own in its very earliest stages of formation. The research community has long sought such a system to help us understand the ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

CAPE CANAVERAL, Fla. — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

The birth of a new solar system may have been caught on camera. About 1,400 light-years from Earth sits a young sunlike star surrounded by cooling gas and teensy silicate minerals. These mineral ...
