There's an Earth-Sized World Nearby

The closest star to the Sun is a small red dwarf star known as Proxima Centauri. It is only 4.2 light-years away and is now known to have an Earth-sized planet in its habitable zone.

Two Newborn Planets Orbiting a Distant Star

A new study presents the first-ever direct images of twin baby planets forming around their star. The proud mama is PDS 70, a star in the Centaurus constellation. It’s about 370 light years away.

Pictures of Planet-Forming Disks Around Young Stars

Astronomy is advancing to the point where we can see planets forming around young stars. This was an unthinkable only a few years ago. It was only two years ago that astronomers captured the first image of a newly-forming planet.

Exoplanet disappears in latest Hubble observations

The object, called Fomalhaut b, was first announced in 2008. It was clearly visible in several years of Hubble observations that revealed it was a moving dot. Now it has vanished and scientists seek for a plausible explanation.

Planet System In Near Perfect Rhythm With Each Other

The system around HD 158259 star consists of an innermost large rocky planet (a “super-Earth”) and five small gas giants (“mini-Neptunes”) that have exceptionally regular spacing between them. 

Earth-size, habitable-zone planet found

A reanalysis of data from NASA's Kepler space telescope has revealed an Earth-size exoplanet orbiting in its star's habitable zone, the area around a star where a rocky planet could support liquid water.

The Cheops space telescope is ready to study exoplanets

Cheops (Characterising Exoplanet Satellite), the satellite for the study of the exoplanets of the European Space Agency (Esa), has passed the exams and now it is ready to go to work. 

Astronomy student discovers 17 new planets

US astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA.

Exoplanet could have the right conditions for life

Astronomers have found an exoplanet more than twice the size of Earth to be potentially habitable, opening the search for life to planets significantly larger than Earth but smaller than Neptune.

TESS finds its first Earth-size planet in habitable zone

The habitable-zone planet is one of three orbiting a star known as TOI 700, a cool M dwarf located about 100 light-years from Earth. The candidate planet, TOI 700 d, is is at a distance where temperatures would allow water to exist in liquid form.

ESA's CHEOPS mission Just Launched Successfully

CHEOPS stands for the Characterizing Exoplanet Satellite. It’s a partnership between ESA and Switzerland, with 10 other EU states contributing. Its mission is not to find more exoplanets, but to study the ones we already know of.

In a first, astronomers find a planet orbiting a white dwarf

In the first observation of its kind, astronomers using the Very Large Telescope in Chile have found evidence of a Neptune-size planet orbiting a white dwarf, the collapsed remnant of a Sun-like star that has run out of nuclear fuel. 

A Place on Earth with Liquid Water But No Life

 We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.

TESS is finding hundreds of exoplanets

TESS is likely to find between 10,000 and 15,000 exoplanet candidates by 2025. By 2030, the European Space Agency’s GAIA and PLATO missions are expected to find another 20,000-35,000 planets. 

Nobel Prize in Physics 2019

Half the prize went to cosmologist Jim Peebles, and the other half was awarded jointly to Michel Mayor and Didier Queloz for the first discovery of an exoplanet orbiting a sun-like star.
