JWST sees four exoplanets in a single system

When the JWST activated its penetrating infrared eyes in July 2022, it faced a massive wish-list of targets compiled by an eager international astronomy community. Distant, early galaxies, nascent planets forming in dusty ...

Do red dwarfs or sunlike stars have more Earth-sized worlds?

Earth is our only example of a habitable planet, so it makes sense to search for Earth-size worlds when we're hunting for potentially-habitable exoplanets. When astronomers found seven of them orbiting a red dwarf star in ...

JWST observes the Kuiper Belt: Sedna, Gonggong, and Quaoar

The Kuiper Belt, the vast region at the edge of our solar system populated by countless icy objects, is a treasure trove of scientific discoveries. The detection and characterization of Kuiper Belt Objects (KBOs), sometimes ...

An ambitious new technology might be needed to see other Earths

The race is on to discover truly habitable Earth-like worlds. While we are starting to observe the atmospheres of large potentially habitable planets such as Hycean worlds with the telescopes we currently have, the most significant ...

JWST accidentally discovers 21 brown dwarfs

When you launch humanity's most powerful telescope, you expect results. The JWST has delivered excellent results by detecting ancient galaxies, identifying chemicals in exoplanet atmospheres, and peering into star-forming ...

Using cosmic weather to study which worlds could support life

As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away ...
