Black Holes May Fill the Universe with Seeds of Life Posted: 1 year ago by AutumnLotus
New research shows that black holes are not the ultimate destroyers that are often portrayed in popular culture. Instead, warm gas escaping from the clutches of enormous black holes could be one source of the chemical elements that make life possible.

Astronomers Devise New Way to Weigh Black Holes Posted: 1 year ago by AutumnLotus
Astronomers can't see black holes. And they definitely can't go out and grab a piece of one to measure its mass.
So how do they weigh them?

Some Black Holes May Not Be Black, But Rather 'Naked Singularities' Posted: 1 year ago by AutumnLotus
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. Finding such an unmasked form of what physicists term a singularity "would shock the foundation of general relativity."

Supermassive black holes about to get much brighter! Posted: 2 years ago by 2manyusernames
Spitzer Space Telescopes show that the vicinities around the black holes could be backing up with excess matter - the black holes just can’t consume it fast enough to clear the space. When this happens, the matter heats up, and releases a tremendous amount of energy.

Hundreds of 'Missing' Black Holes Found Posted: 12 months ago by AutumnLotus
Hundreds of "missing" black holes have been found lurking in dusty galaxies billions of light-years away. The finding is the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths constructing supermassive black holes at their cores.

Astronomers puzzled by cosmic black hole Posted: 1 year ago by 2manyusernames
Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all.

Study confirms supermassive black holes produce powerful galaxy-shaping winds Posted: 11 months ago by AutumnLotus
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth. The RIT team has, for the first time, observed the vertical launch of rotating winds from glowing disks of gas, known as accretion disks, surrounding supermassive black holes in the centers of galaxies.

Mid-Size Black Hole Answers Longstanding Question Posted: 6 months ago by AutumnLotus
Black holes can't be seen, but they're detected by noting their effects on stars or gas around them. They're so dense that nothing, including light, escapes them. Only two classes of black holes are firmly established to exist: Stellar black holes typically weigh a few times the mass of the sun; supermassive black holes are loaded with millions or billions of solar masses.

Green, Oolong, Black - The Legendary Teas Posted: 1 year ago by TeaAvenue
A native of China and one of the oldest medicinal herbs, camellia sinensis is a tall evergreen shrub that blooms with white followers that resemble dogwood roses. This is the shrub that started the legend of tea in 2737 B.C. when the fresh leaves fell into the boiling water of Chinese Emperor Shen Nung, the father of Chinese medicine. Today, there are more than three thousand species of the shrub that yield hundreds - if not thousands - of varieties of the most popular teas in the world - green, oolong from leaves that are mildly fermented; and black, the most pungent of the teas, comes from fully fermented leaves.

Milky Way's antimatter linked to exotic black holes Posted: 9 months ago by AutumnLotus
Legions of tiny black holes created during the big bang may lurk at the centre of the galaxy, creating a prodigious antimatter factory, a new study suggests. The work could explain where the Milky Way's antimatter comes from – one of the biggest mysteries in astrophysics.

Colossal Black Hole Shatters the Scales Posted: 9 months ago by AutumnLotus
The most massive black hole in the universe tips the cosmic scales at 18 billion times more massive than the sun, astronomers suggest today at a meeting of the American Astronomical Society. Even though researchers suggested black holes up to this mass might exist in quasars, this is the first direct confirmation of such a behemoth.

Chandra data reveal rapidly whirling black holes Posted: 9 months ago by AutumnLotus
A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth.
