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 [...]

Extreme Red Quasars May Quash Formation Of Stars

Billions of years ago, galaxies formed and grew through accumulation of gas from their surroundings, or colliding and merging with other young galaxies. These early stages of galaxy assembly are believed to be accompanied by episodes of rapid star formation, known as starbursts, and rapid growth of a single super-massive black hole in the galactic [...]

Early Universe Cosmic Microwave Background 3D Printed

A 3D printed map of the oldest light in the universe has been created by researchers at Imperial College London, and you can download the files and your print your own baby universe. The cosmic microwave background is a glow that the universe has in the microwave range that maps the oldest light in the [...]

Galactic Warming From Supermassive Black Holes

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 [...]
