‘Oumuamua Interstellar Object: Scientists Shed New Light on Origins of Cigar-shaped Space Rock

Yahoo Science News feed latest items - Mon, 03/19/2018 - 10:11

In October 2017, astronomers spotted a strange, incredibly fast-moving object hurtling through the solar system. 'Oumuamua—a Hawaiian term roughly translating to “scout” or a “messenger from afar”—is thought to measure around 800 by 100 feet and has a rare cigar-like shape. It is currently hurtling through the solar system at incredible speeds—around 16 miles per second—although it is tumbling rather than smoothly rotating.

Stem cell eye treatment safe, restores some vision: study

Yahoo Science News feed latest items - Mon, 03/19/2018 - 10:03

Two people with severe vision loss due to a degenerative eye disease are able to read after embryonic stem cell treatment, researchers said Monday. The pair suffer from "wet" age-related macular degeneration, which can blur vision or cause a blind spot when abnormal blood vessels leak fluids into the eye, causing damage to a layer of cells called the retinal pigment epithelium (RPE). For the study, a British-American research team used human embryonic stem cells (hESC) to grow RPE cells on a thin plastic scaffold.

Black Hole Belches Bright Radio Flashes as It Devours Nearby Star

Yahoo Science News feed latest items - Mon, 03/19/2018 - 09:26

Black holes are voracious eaters, but they don't have the nicest table manners. As they rip into a star, they tend to produce a bright flash of light that astronomers call a tidal disruption flare, the celestial equivalent of all the applesauce that fails to quite make it down a baby's throat. “This is the first time we’ve seen a jet that’s controlled by a feeding supermassive black hole,” co-author Dheeraj Pasham, an astronomer at MIT, said in a press release.
