that further support the notion that this planet is more like a super-Venus rather than a mini-Neptune. This finding defies current assumptions and brings new possibilities to the classification ...

The celestial body named GJ 1214 b or Enaiposha received a classification of mini-Neptune due to its planetary size and mass measurements. The James Webb Space Telescope (JWST) observed Enaiposha and ...

The finding points toward two different pathways by which large and small planets form. "What we found is that right around the size of Neptune, planets go from being almost always on circular ...

The research team used data from NASA's Transiting Exoplanet Survey Satellite (TESS) to study young sub-Neptunes—planets bigger than Earth but smaller than Neptune—that orbit close to their stars.

“I am incredibly excited to work across disciplines here to help unravel the mysteries of sub-Neptune planets.” Building new models for mysterious worlds Mukherjee, a PhD candidate at the ...

Mundell added that as our understanding of the universe has developed over many years, we have come to understand that the "ordinary matter" that composes stars, planets, moons, asteroids ...

These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future atmospheric studies to better understand these ...

A rare cosmic event will grace the night sky Friday. Astronomers are calling it a once-in-a-generation wonder as the next will not happen again until 2040.
