The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315 that resembles a young version of the Earth's own sun. Using data from ground and ...

HIP 67522 is also a far more active star than our sun, and routinely emits much stronger energy flares. It also hosts two planets, but HIP 67522 b has a faster orbit than its sibling and takes ...

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 ...

Adapting to the whims of a star is no small task, however. The sun may appear to be constant from day to day, but let time stretch out for millions or even billions of years, and things do change ...

About 400 light-years away, the star, HIP 67522, is young — just 17 million years old — and violent. It's slightly bigger and cooler than the sun but more energetic, spinning fast.

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show.

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider ...
