Visible planets and night sky guide for May 2024. Tonight (May 20), see the waxing gibbous moon near the bright star Spica.
Researchers said the bunching of small objects beyond Neptune fits perfectly with the existence of a Planet 9 hiding on the outskirts of our solar system.
There's a lineup of 6 planets in the morning sky in early June. But four of them aren't easy to see. Find charts and observing tips here.
NASA's Webb telescope has tentatively detected an atmosphere on rocky exoplanet 55 Cancri e, a hot super-Earth world only 41 light-years away.
NASA's Webb telescope has mapped the weather on WASP-43 b, a hot Jupiter exoplanet 283 light-years away. It's blistering hot with 5,000-mile-per-hour winds.
NASA's Webb telescope looked at the sub-Neptune exoplanet K2-18 b. It found methane, carbon dioxide, a possible ocean, and even ... maybe ... a biosignature.

NASA's Webb space telescope looked for baby planets in the protoplanetary disks in 3 young planetary systems. It didn't find any, and scientists explain why.
For the 1st time, astronomers say they have detected a glory on an exoplanet. Glories are a natural phenomenon, but until now seen only on Earth and Venus.
Astronomers using NASA's Webb telescope have discovered and imaged two possible giant planets orbiting white dwarfs less than 75 light-years away.
A new survey looked at 86 young stars and their planet-forming disks in 3 gas clouds in our own Milky Way. See the wide variety of dusty disks here.
Researchers at Yale University said habitable planets in binary star systems - so-called Tatooine exoplanets - may be more common than previously thought.
Astronomers have found the smallest exoplanet yet with water vapor. GJ 9827 d is a hot steamy world. But is it rocky like Earth or a mini-Neptune?
Researchers at UCLA have found an exoplanet with a tail. The hot Jupiter WASP-69b has a huge comet-like tail of gas 350,000 miles (560,000 km) long.
A new study says that an exoplanet 50 light-years away is either a water world or a mini-Neptune. NASA's Webb telescope might tell us which it is.
A new study says that rocky habitable exoplanets likely have less carbon dioxide in their atmospheres as compared to similar planets in the same system.
With 3 years of data, astronomers using the Hubble telescope say they've simulated weather patterns on distant planet Tylos some 800 light-years away.
For the 1st time, astronomers have used an instrument designed to study exoplanets - ESPRESSO, on the Very Large Telescope - to observe the planet Jupiter.
Learn about Michael Carroll's book Planet Earth, Past and Present. The richly illustrated book looks at history, habitability, our solar system and more.
The James Webb Space Telescope has discovered something unexpected in the Orion Nebula: pairs of unusual planet-like 'binary objects' drifting freely in space.
