exoplanets

[astro-ph.EP]. Beta Pictoris is a young and nearby planetary system hosting an edge-on debris disk and at least three gas-giant planets. Their circumplanetary environments could host exomoons and rings, a […] The post The Hill Sphere Transits of Beta Pictoris c and The Search for Another 1981-like Event appeared first on Astrobiology .

KMT-2025-BLG-0975L b is a Neptune-like exoplanet that orbits a Unknown-type star. Its mass is 29.8 Earths, it takes 2.3 years to complete one orbit of its star, and is 0.81 AU from its star. Its discovery was announced in 2026. The post KMT-2025-BLG-0975L b appeared first on NASA Science .

[astro-ph.EP] Accurate stellar ages are fundamental to interpreting the evolutionary histories of habitable zone (HZ) planets. Because stellar luminosity evolves over time, HZ boundaries migrate outward, meaning that present-day HZ […] The post Precise Stellar Age Constraints and Habitable Zone Evolution in Exoplanet Systems appeared first on Astrobiology .

[astro-ph.EP] The field of exoplanetary research is rapidly evolving, thanks to TESS and Kepler/K2. With the latest data release, Gaia DR3, Gaia has transformed the study of star clusters. By […] The post Exoplanets In Star Clusters appeared first on Astrobiology .

Hi everyone, I wanted to start a discussion about one of the most fascinating questions in science: are we alone out there? Given that there are billions of Earth-like exoplanets in our galaxy alone, the odds seem high that life could exist elsewhere. However, we haven't found any definitive... Read more

The Kepler telescope changed how we saw the sky. It’s just one of the devices we’ve sent out beyond the reach of humans to search our solar system

[University of Chicago] In the search for extraterrestrial life, it makes sense to first look for rocky planets with an atmosphere, like Earth. Without an atmosphere, a planet can’t have […] The post Atmosphere Detected On The Coldest Lava World To Date appeared first on Astrobiology .

Astronomers have discovered a new giant mega-Earth exoplanet that is a whopping 23 times as massive as Earth, and 2.5 times the size. The post Giant mega-Earth is 23 times more massive than Earth first appeared on EarthSky .

[astro-ph.EP] Recent observations of V1298-Tau b, a warm sub-Neptune (R=9.85±0.3R⊕, M=13.1±5.3,M⊕, Teq=670K) orbiting a young (10-30Myr) K star, show depleted methane and surprising abundances of CO2 in its atmosphere. This […] The post Stellar Flares Rather Than High Tint As Possible Cause For the Missing Methane In Young Exoplanets: The Case Study of V1298-Tau b appeared first on Astrobiology .

[astro-ph.IM] To support the development of next-generation missions for the search and characterization of habitable planets, high-fidelity tools for astrophysical and instrumental noise simulations are needed. In this paper, we […] The post pyEDITH: The Coronagraphic Exposure Time Calculator For The Habitable Worlds Observatory appeared first on Astrobiology .
