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 ...

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 ...

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 ...

One way to find water worlds beyond our solar system could be to look for minerals — or more specifically, to study minerals mixed with cool lava on exoplanet surfaces. This is because if water comes ...

The planets have been nicknamed Earth's seven sisters. — -- An international team of astronomers has discovered seven potentially habitable exoplanets — or planets outside our solar system — that ...

The team discovered that the surface might contain liquid water, an essential ingredient for life. Astronomers from the, Irvine have discovered a planet orbiting within the “habitable zone” of its ...

There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA’s WFIRST space telescope, according to new models of gas ...

Exoplanet discoveries have reshaped astronomy. Are exomoons next? Brian Greene in conversation with David Kipping ...

These days, researchers commonly discover exoplanets, or planets outside our solar system. But sometimes there’s a special discovery, like an exoplanet right in our backyard — and that’s the case with ...

The sulfur-laden atmosphere discovered on gaseous exoplanet GJ 3470 b, show here in an illustration orbiting its star in the constellation Cancer, could help researchers figure out how it (and similar ...
