A team of professional and amateur Japanese astronomers have found evidence for a thin atmosphere around a small body in the outer solar system. The object is so small that it should not have a sustai...

Four worlds around a small, dim star are challenging theories of planet formation

Ultra-short period (USP) exoplanets -- with $R_p \leq 2~$R$_{\oplus}$ and periods $\leq$1 day -- are expected to be stripped of volatile atmospheres by intense host star irradiation, which is corrobor...

Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefits to both approache...

We uniformly combined data from the NASA Kepler and K2 missions to compute planet occurrence rates across the entire FGK and M dwarf stellar range. The K2 mission, driven by targets selected by guest ...

From pebbles to planets

The objects around the ringed planet are tiny, but some of them may have formed relatively recently in the solar system’s history.

An international team, led by a student from Instituto de Astrofísica de Canarias (IAC), has detected a super-Earth orbiting in the habitable zone of GJ 3998, a nearby red dwarf located 59 ly away. The new planet, named GJ 3998 d, is the third planet found in the system.

Researchers at the University of Arizona have discovered that planet-forming disks of gas and dust around tiny stars live much longer than previously thought. The findings provide new insights into pl...

State-of-the-art JWST observations are unveiling unprecedented views into the atmospheres of substellar objects in the infrared, further highlighting the importance of clouds. Current forward models s...
