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 ...

New massive brown dwarf discovered

Astronomers report the discovery of a new massive brown dwarf using the Zwicky Transient Facility (ZTF). The newly detected object is about 80 times more massive than Jupiter and orbits a low-mass star. The finding was detailed ...
