A Jupiter-sized planet has been hiding a big secret: A 350,000-mile-long tail
WASP-69b is having a hot girl summer that never ends. The huge gaseous exoplanet, roughly the size of Jupiter and approximately 160 light years from Earth, orbits its searing host star so closely that its atmosphere is boiling away at a rate of 200,0.....»»
Secrets of a hot Saturn and its spotted star unlocked
A team of astronomers including McGill Professor Nicolas Cowan has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star's activity.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»

Planet WASP-121 b has a surface temperature of 5,000 degrees Fahrenheit, which researchers predict would lead to some wild weather phenomena......»»
TRAPPIST-1c isn"t the exo-Venus we were hoping for, but don"t blame the star
A recent study posted to the arXiv preprint server and accepted to The Astrophysical Journal uses computer models to investigate why the exoplanet, TRAPPIST-1c, could not possess a thick carbon dioxide (CO2) atmosphere despite it receiving the same a.....»»
The atmosphere of an exoplanet reveals secrets about its surface
As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface of a planet from view. A.....»»
Researchers argue back and forth about whether we’ve spotted an exomoon

Astronomers scan hundreds of stars for "anomalous transits"
Telescopes have been collecting copious amounts of data on exoplanets in recent years. One of the most common datasets tracks what are known as transits, when an exoplanet crosses in front of its host star and dims the star's light slightly as it doe.....»»
Massive planet too big for its own sun pushes astronomers to rethink exoplanet formation
Imagine you're a farmer searching for eggs in the chicken coop—but instead of a chicken egg, you find an ostrich egg, much larger than anything a chicken could lay......»»
Neptune-sized exoplanet is too big for its host star
Stars this small shouldn't make planets this big. Enlarge (credit: NASA/JPL-Caltech) You win some, you lose some. Earlier this week, observations made by the Webb Space Telescope provided new data that supports what we t.....»»

Astronomers discover two "hot Jupiters" orbiting red-giant stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit distant red-giant stars. The.....»»
Webb identifies methane in an exoplanet"s atmosphere
The James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a doz.....»»
