The exoplanet TIC 241249530 has an extremely elongated, cucumber-shaped orbit.making a sharp “hairpin turn” each time it approaches its star. The exoplanet also orbits its star in reverse.another rare phenomenon among observed transiting exoplanets. Scientists believe TIC 241249530 could be transforming into a hot Jupiteroffering information on planetary migration processes. Exoplanet with an extreme orbit
Astronomers have spotted the first jet from an S-shaped neutron starThe jet is part of the Circinus X-1 binary star system. The neutron star's jet sprays like a garden sprinkler.changing direction due to the motion of hot gas around the star. Astronomers had observed precession with jets around black holes. Before, but never with neutron

Join EarthSky Deborah Byrd and astronomer Michael Brown LIVE at 12:15 p.m. CDT (17:15 UTC). Will the definition of a planet change? Brown is a professor of planetary astronomy at the California Institute of Technology. His 2012 book is called “How I Killed Pluto and Why It Deserved It.” He helped discover our solar system’s

Comet Tsuchinshan-Atlas may be disintegrating Observers around the world have been waiting for the next great comet to become visible to the naked eye. And many thought Comet Tsuchinshan-ATLAS might be it! Discovered
Artist's conception of HD 189733 b. A new study by researchers at Johns Hopkins University has found that the gigantic, stinky exoplanet smells like rotten eggs.

Exoplanets are worlds that orbit distant stars. Astronomer Nestor Espinoza of the Space Telescope Science Institute spoke to EarthSky Deborah Byrd On Monday, May 20, 2024, he talked about this diversity of worlds beyond our Sun and planets. He talked about the nearby and fascinating TRAPPIST-1 system, located about 40 light-years away. He talked about
A comet explosion nearly killed humanity 12,800 years ago About 12,800 years ago, a geological blink of an eye, global temperatures plummeted suddenly and dramatically. The frigid conditions of the Younger Dryas cooling period lasted more than 1,200 years. But it shouldn't have happened. The Earth was warming when the cooling began. On June 25,
