Dark Exoplanet WASP-12b Devours 94 Percent Of Visible Starlight

An exoplanet located beyond our solar system observed by NASA’s Hubble Space Telescope appears as black as asphalt because it “eats” light rather than reflecting it back into space, new research suggests. This light-eating ability is due to the planet’s unique prowess at trapping at least 94 percent of the visible starlight falling into its […]

A Huge Hydrogen Halo Envelops The Milky Way

Gazing on 732,225 galaxies with the 2.5-meter telescope of the Sloan Digital Sky Survey has revealed the veil of diffuse hydrogen gas enshrouding the Milky Way. After combining this staggering number of spectra — recorded patterns of wavelengths revealing clues about the nature of a cosmic target — astronomers Huanian Zhang and Dennis Zaritsky report […]

A new class of galaxies, called “red geysers,” with supermassive black hole winds so hot and energetic that stars can’t form, has been uncovered by an international team of scientists. Over the last few billion years, a mysterious kind of “galactic warming” has caused many galaxies to change from a lively place where new stars […]
