A team of astronomers discovered at least 70 ‘rogue’ planets in our galaxy, the largest collection ever found to date. While conventional planets (like those in our Solar System) orbit a star, rogue ...

This artist's impression shows HIP 13044 b, an exoplanet orbiting a star that entered our galaxy, the Milky Way, from another galaxy. ((L. Calçada/ESO) ) Astronomers say they've found the first known ...

Alien planets are incredibly common in our Milky Way galaxy, outnumbering stars by a large margin, a new study suggests. On average, each of the 100 billion or so stars in our galaxy hosts at least ...

"We know we are making an exciting and bold claim so we expect that other astronomers will look at it very carefully," said one researcher. "We think we have a strong argument, and this process is how ...

Astronomers have discovered a massive gas giant, TOI-6894b, orbiting the red dwarf star TOI-6894, a pairing that defies current planetary formation theories. This planet, slightly larger than Saturn ...

The Milky Way, the galaxy that houses our solar system, is an enormous and complex structure filled with mysteries, motion and magnificent phenomena. Despite being our galactic home, many of us know ...

TORONTO – Astronomers have spotted one of the most distant exoplanets ever seen — about 13,000 light-years away. While there have been roughly 1,800 confirmed exoplanets to date (with thousands more ...

Orbiting a small, cool M dwarf star once every 4,170 days, the planet's location is remarkable — it is only the third planet in the entire history of space observation to be discovered so far away ...

When Fermi posed his famous question, “where are they” we hadn’t identified a single planet beyond our solar system. The 1995 discovery of the first exoplanet allowed scientists to break the guestion ...

Tens of billions of rocky planets in the Milky Way are the right temperature to support liquid water, a new study estimates. In fact, within 30 light years of our own solar system, there are likely ...
