The inner workings of black holes are still mysterious to scientists, but some physicists might have a new theory about what happens when matter falls into a black hole.
A Kavli Foundation webcast detailing that new theory will begin at 3 p.m. EDT (1900 GMT) and you can use the hashtag #KavliLive to submit questions on Twitter. Theoretical physicists Raphael Bousso, Juan Maldacena, Joseph Polchinski and Leonard Susskind will take part in the event. Watch the webcast in the window below:
SLOOH Webcast about Deep Space Mysteries Thursday (Sept. 26) @ 8 p.m. EDT
From SLOOH: SLOOH will open its observatory to exploring the mind-bending topic of cosmic motion. Which way is Earth going, and how fast?
REPLAY: The Harvest Moon
The Harvest Moon shined bright on Thursday (Sept. 19), and online skywawtchers caught views of the famous moon online. The Slooh Space Camera, an online stargazing service, which broadcast high-definition views of the rising moon from a partner facility in Prescott, Ariz., beginning at 10 p.m. EDT (0200 Sept. 19 GMT). A broacast team will provide commentary during the live webcast.
"The Harvest Moon is the most famous full Moon of the year, by far," Bob Berman, Slooh broadcast team member, said in a statement. "Yet it’s bathed in widespread myth and misconception. During our live show, we intend to combine science, lore, and mythology to provide an accurate picture of this annual lunar event." You can watch the feed live in the window below, or directly from the Slooh Space Camera website and the Slooh iPad app.

Mars and the Beehive: LIVE Monday @ 1:30 a.m. EDT (0530 GMT)
Slooh's night sky webcasts continue early Monday, Sept. 9, at 1:30 a.m. EDT (0530), when Mars will be visible as it enters the so-called Beehive Cluster.
According to Slooh officials, "watch real-time images of the Red Planet Mars as it enters the Beehive Star Cluster. This beautiful visual spectacle is an optical illusion as the Beehive Cluster is actually 577 light-years away."

WEBCAST REPLAYS
Astrophysicist Gianluca Masi of the Virtual Telescope Project in Italy will webcast live views of the Nova Delphinus 2013, a star explosion discovered in August that is now fading away. The webcast will begin today (Sept. 3) 5 p.m. EDT (2100 GMT). PHOTOS: New Star Explosion: Photos of Nova Delphinus 2013: Gallery
You can watch the event on SPACE.com in the window below or directly from the Virtual Telescope Project here: http://www.virtualtelescope.eu/webtv/
Called Nova Dephinus 2013, the new nova (Latin for "new star") was discovered Aug. 14 by amateur astronomer Koichi Itagaki of Yamagata, Japan, 2 p.m. EDT (1800 GMT) in the constellation Delphinus, the Dolphin. Itagaki used a CCD camera attached to a 7-inch reflecting telescope. A nova is a powerful explosion from star, but is not as strong as a supernova, which is a catastrophic explosion that signals the death of a star.
