But those claims were quickly met with pushback. Independent analyses of the same JWST data suggested the team's evidence for DMS was weak at best, while other experts cautioned that sub-Neptunes may ...

In a remarkable feat of astronomical discovery, scientists have identified a new exoplanet similar in size to Earth, but with one notable difference: it is covered in vast, glowing lava oceans. This ...

An exoplanet orbiting a dwarf star 124 light-years from Earth made headlines around the world in April 2025. Researchers at the University of Cambridge reported that planet K2-18b could be a marine ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

A low-density, puffy planet orbiting relatively far from a young star in a nearly perpendicular orbit. What's going on?

Scientists using NASA's Transiting Exoplanet Survey Satellite (TESS) discovered an exoplanet, which NASA defines as “any planet beyond our solar system.” What's False However, the “strange signals” ...

In the search for habitable exoplanets, atmospheric conditions play a key role in determining if a planet can sustain liquid water. Suitable candidates often sit in the "Goldilocks zone," a distance ...

Exoplanet TRAPPIST-1 e may contain an atmosphere and liquid water, NASA scientists said. Research into the exoplanet is ongoing.

The discovery of the Kuiper Belt fundamentally reshaped our understanding of the solar system's architecture and population, revealing a far larger and more complex system than previously imagined.
