New research using NASA's powerful JWST telescope has identified a planet 41 light years away which may have an atmosphere.

But all of those planets reside within our own Milky Way galaxy. Tiny and dim in comparison to stars, planets beyond our galaxy's boundaries are extremely difficult to spot.

X-rays may have revealed the first planet outside our galaxy Process may point to a general means of finding very distant planets.

New estimates and calculations suggest that there are more Earth-like planets and ocean worlds in our galaxy, according to new research by astronomers published this week. There may be as many as ...

Our Milky Way galaxy is massive at around 100,000 light-years across, making the prospect of directly observing any planets beyond our galaxy with conventional telescopes basically impossible. But ...

Interest in steam world exoplanets really heated up in October 2024 when the James Webb Space Telescope (JWST) discovered the ...

100 Million Planets in our Galaxy May Harbor Complex Life One percent of all exoplanets may be suitable for complex organisms, according to a new estimate based on data rather than guesswork.

Astronomers may have found a planet in the Whirlpool Galaxy. If so it's the first planet seen to transit a star outside of the Milky Way—and it may represent a new way to find "extroplanets." ...

It's very likely (in fact, it's practically certain) that planets exist outside of our galaxy -- we just haven't been able to detect them yet.

Number of potentially habitable planets in our galaxy: Tens of billions A new statistical analysis allows astronomers to more rapidly assess planethood.

Cold planets seem to be present throughout our galaxy, even in the galactic bulge, where their existence was uncertain.

Astronomers have discovered a giant Saturn-sized planet orbiting TOI-6894, the smallest star ever known to host such a world.
