Astronomers have discovered a unique planetary system where planets are arranged inside out
The fourth planet in the system is a rocky world, while the second and third ones are gas planets.
"The most likely explanation for the dimming is a brown dwarf – an object heavier than a planet but lighter than a star – surrounded by a vast and dense ring system." When you purchase through links ...
Like a double-stuffed Oreo of planetary proportions, the star LHS 1903 boasts two rocky exoplanets sandwiching two gaseous ones. From the star outward, the lineup — rocky-gaseous-gaseous-rocky — ...
A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...
A totally original creation from the team behind the Black Mesa Half-Life remake, Rogue Point has been blipping on my radar for a while now. While it has a lot of the hallmarks you'd expect from ...
An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...
ESA’s CHaracterising ExOPlanet Satellite (CHEOPS) has revealed a four-planet system whose outermost world is a small and rocky planet — not a gas giant. The unexpected arrangement around the nearby ...
Astronomers have long been puzzled by the near-absence of planets orbiting close pairs of stars. New theoretical work shows that subtle relativistic effects can slowly drive such planets into extreme, ...
A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...
Hydrogen sulfide is what makes rotten eggs stink. But the discovery of this gas in the atmospheres of four distant, Jupiter-like planets is turning heads for a pleasant reason: It solves the mystery ...
There’s a comforting idea in planetary science. That no matter how strange a distant world looks, its beginnings might still feel familiar. For decades, astronomers have argued about how super ...
