Researchers have identified the first signature of a magnetic field surrounding a planet outside of our solar system. Earth’s magnetic field acts as a shield…
The more than 70 sunless worlds are each roughly the mass of Jupiter. Using observations and archival data from several of NSF’s NOIRLab’s observatories, together…
The planetary nature of a Mars-sized object orbiting extremely closely to an M-dwarf star has been validated using the Penn State Habitable-zone Planet Finder (HPF)….
Rogue planets are elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star,…
ESA and Airbus have signed a contract to move forward with the design and construction of the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, Ariel, planned for…
New planetary candidates found by sifting through archival Kepler Telescope data. A fully automated exoplanet-detection system sifted through years of data from NASA’s retired Kepler…
New study finds a world about 146 light years away that’s not quite a planet, not quite a brown dwarf. Citizen scientists have discovered a…
ESA’s trifecta of dedicated exoplanet missions – Cheops, Plato, and Ariel – will also be complemented with the upcoming James Webb Space Telescope mission. The…
As far as extrasolar planets go, ‘GJ 367 b’ is a featherweight. With half the mass of Earth, the newly discovered planet is one of…
The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has captured an image of a planet orbiting b Centauri, a two-star system that can be…
Planets without plate tectonics are unlikely to be habitable. But currently, we’ve never seen the surface of an exoplanet to determine if plate tectonics are…
An international team of researchers has discovered a new planet, GJ 367 b, whose surface temperature may reach 1,500 degrees Centigrade – hot enough to…
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date. Ultra-short-period planets are small, compact…
Strange ‘eggshell planets’ are among the rich variety of exoplanets possible, according to a study from Washington University in St. Louis. These rocky worlds have…
Mercury is the speed champion in our Solar System. It orbits the Sun every 88 days, and its average speed is 47 km/s. Its average…
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant. The hunt for planets beyond our solar system has turned up…
Findings also include a distinctive planetary system with two gas giants. UCLA astronomers have identified 366 new exoplanets, thanks in large part to an algorithm…
Fragile orbits of seven exoplanets limit late arrival of water. Seven Earth-sized planets orbit the star TRAPPIST-1 in near-perfect harmony, and U.S. and European researchers…
