Astronomers from the Harvard–Smithsonian Center for Astrophysics (CfA) and elsewhere, report the discovery of a new 'warm Jupiter' exoplanet orbiting a rapidly rotating F-type star. The newfound alien world, designated ...
Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. ...
Only two of the more than 5,300 known exoplanets have so far provided evidence of moons in orbit around them. In observations of the planets Kepler-1625b and Kepler-1708b from the Kepler and Hubble space telescopes, researchers ...
An international team of astronomers has discovered a new warm Jupiter exoplanet orbiting a distant G-type star. The newfound alien world, designated TOI-4515 b, is similar in size to Jupiter but about two times more massive ...
Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.
Imagine you're a farmer searching for eggs in the chicken coop—but instead of a chicken egg, you find an ostrich egg, much larger than anything a chicken could lay.
The Earth's magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it moves.
On a crisp, sunny day high in the Peruvian Andes, two German judges gaze across a mountain lake to the towering white glaciers in the distance. Dark spots are visible on the pristine ice and, in quiet moments, the cold wind ...
Scientists have long puzzled over why all of the planets in Earth's solar system have slightly slanted orbits around the sun. But a new, Yale-led study suggests this phenomenon may not be so unusual after all. Even in "pristine" ...
On 17 November 2023, ESA's Juice spacecraft carried out one of the largest and most important maneuvers in its eight-year journey to Jupiter.
