Cheops Finds an Utterly Alien World

The ESA’s CHEOPS (Characterizing Exoplanets Satellite) mission has announced its first discovery. It’s called WASP-189 b, and it’s a blistering hot temperature of 3,200 °C. They’re calling the planet an “ultra-hot Jupiter.”

An Earth-Mass Planet Without A Star Found

Once a star left the gravitational embrace of its solar system, its pretty much destined to drift through interstellar space forever. Astronomers call these drifters “rogue planets” and one of them have been found recently.

In a first, intact planet found in close orbit around white dwarf

Astronomers have discovered what appears to be an intact, Jupiter-size planet ( WD 1856 b ) whipping around a compact white dwarf, the remnant of a Sun-like star.

Researchers find exoplanet with pi-like 3.14-day orbit

Researchers have found an Earth-size exoplanet with a pi-like 3.14-day period. Whirling around its star at some 291,000 kph, the planet’s surface temperature is estimated at around 176 degrees Celsius. 

Actual Picture of Multiple Planets Orbiting a Star

Direct images of exoplanets are pretty rare. This is the first direct image of multiple exoplanets orbiting a star similar to our Sun taken by The European Southern Observatory’s Very Large Telescope (VLT).

There Are 6 Billion Earth-Like Planets in the Milky Way

An Earth-like world is one that’s rocky and that orbits a Sun-like, or G-Type, star. The Milky Way has 400 billion stars, with 7 % of them being G-type, meaning that less than six billion stars may have Earth-like planets in our Galaxy.

Second Proxima Centauri planet confirmed

The red dwarf Proxima Centauri, just 4.2 lights years away. Recently, U.S. astronomers using data collected from the Hubble Space Telescope 25 years ago, have confirmed the presence of an exoplanet Proxima Centauri c.

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.
