An international team of astronomers has shown for the first time that it is possible to map exoplanets using a technique ...

A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively. This makes TOI-4465 b a rare case of a giant planet ...

Using NASA's planet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite), astronomers have discovered three ...

Astronomers have discovered a relatively cool and small exoplanet orbiting a nearby star, with a “year” of several months. The find offers a rare opportunity to study planets and solar systems like ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

Retrieval methods are a powerful analysis technique for modelling exoplanetary atmospheres by estimating the bulk physical and chemical properties that combine in a forward model to best-fit an ...

Artist's view of exoplanet SPECULOOS-3 b orbiting its star. The planet is as big as the Earth, while its star is slightly larger than Jupiter, but much more massive. (NASA/JPL-Caltech via Courthouse ...

We have a couple of techniques that allow us to infer the presence of an exoplanet based on its effects on the light coming from its host star. But there's an alternative approach that sometimes works ...

Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our ...

Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting ...

Some stars have stellar winds boasting speeds as great as 5 million miles per hour, deeming even their "habitable zone" planets as not so friendly to life. When you purchase through links on our site, ...

Orbital properties of the 70 cool giants. A comparison of the derived orbital eccentricities from this work (y-axis) versus the orbital periods (previously known) for our planetary candidates sample.
