The Geminid meteor shower is set to peak Saturday (Dec. 13), and you can watch it live in a series of webcasts. Observer's Guide: Must-See Geminid Meteor Shower Peaks This Weekend  The online Slooh Community Observatory will broadcast live views of the Geminids Saturday (Dec. 13) starting at 8 p.m. EST (0100 Dec. 14 GMT), and NASA officials will also host live views of the shower starting at 11 p.m. EST (0400 Dec. 14) GMT. The Virtual Telescope Project will also feature a live broadcast of the shower. Watch that one live here: You can watch the other two live webcasts in the windows below: 

You can also see the Slooh webcast directly through the community observatory's website:

From Slooh: "On the the evening of Dec. 13, under modest moonlight conditions, Slooh will capture the Geminid Meteor Shower using special visual and audio tracking equipment - giving viewers an incredible, real-time dual experience hunting 'shooting stars' by both their visual streaks and ionization 'sounds.'"

Viewers can ask Slooh questions on the meteor shower using the hashtag #sloohgeminids.

"The Geminids are very strange because they hit Earth sideways," Slooh astronomer Bob Berman said in a statement. "It is the difference between being in a car and slamming head on into somebody as opposed to someone backing into you sideways, perhaps coming out of a driveway and crunching into you gently. These meteors hit us gently. While Summer’s Perseids strike Earth at 37 miles per second, that’s amazingly fast, and the Leonids are even a little bit faster, hitting us at just over 40 miles a second, these Geminids hit us at only 22 miles a second."

NASA officials will also answer viewer questions during a live chat from 11 p.m. EST to 3 a.m. EST (0400 GMT to 0800 GMT) on Dec. 13 to Dec. 14. You can ask questions in the chat window that will appear on the NASA Marshall Space Flight Center webpage shortly before the chat begins. 

From NASA: "Geminids are pieces of debris from an object called 3200 Phaethon. Long thought to be an asteroid, Phaethon is now classified as an extinct comet. Basically it is the rocky skeleton of a comet that lost its ice after too many close encounters with the sun. Earth runs into a stream of debris from 3200 Phaethon every year in mid-December, causing meteors to fly from the constellation Gemini. When the Geminids first appeared in the early 19th century, shortly before the U.S. Civil War, the shower was weak and attracted little attention. There was no hint that it would ever become a major display."

Interstellar Spaceflight and Astrobiology with Cameron Smith

Anthropologist Cameron Smith will discuss the biological and cultural aspects of interstellar human spaceflight during a talk today (Dec. 3) at 7 p.m. EST (0000 GMT). Watch it live in the window below, courtesy of the Perimeter Institute for Theoretical Physics in Canada:

"The discovery of countless exoplanets and new ideas in propulsion physics have resurrected international interest in the ancient concept of humanity traveling far beyond Earth," Perimeter Institute officials wrote in a description of the talk. "Such voyages will take place over many generations, requiring careful attention to both biological and cultural change over time. In this talk, Cameron Smith will outline the foundations of a biocultural science of long-term space settlement."

Leonid Meteor Shower: The online Slooh Community Observatory and NASA's Marshall Space Flight Center will offer live webcasts overnight on Monday and Tuesday (Nov. 17-18) for the 2014 Leonid Meteor Shower. Latest Story: Leonid Meteor Shower Peaks Tonight: Watch It Live

Slooh astronomers will offer live views of the 2014 Leonids beginning Monday night at 8 p.m. EST (5 p.m. PST/0100 GMT), and will feature live views from Slooh's flagship observatory at the Institute for Astrophysics in the Canary Islands, as well as views from the Prescott Observatory in Prescott, Arizona. The webcast, which is available at the website and below, will also include sounds of the meteors created by the ionization of the atmosphere as they streak toward Earth. Viewers can follow the webcast on Twitter and ask questions using the hashtag #SloohLeonids

Meanwhile, astronomers at NASA's Marshall Space Flight Center in Huntsville, Alabama will also offer a live webcast of the 2014 Leonid meteor shower using a telescope and a Ustream feed. The webcast will begin at 7:30 p.m. EST (6:30 p.m. CST/0030 GMT) on Monday night. Related: Leonid Meteor Shower Forecast: What to Expect

"We're predicting 10 to 15 meteors per hour," Bill Cooke, head of NASA's Meteoroid Environment Office at Marshall, said in a blog post. "For best viewing, wait until after midnight on Nov. 18, with the peak of the shower occurring just before sunrise." The Marshall webcast will be available on Ustream here, and embedded below.

WARNING: NEVER look a the sun through binoculars or a telescope without using safety filters! Serious eye injury can result. Safety eclipse glasses, and special solar telescope filters are vital for safe viewing of any type of solar eclipse. 

If you do not have safety equipment, you can build a pinhole camera or a solar projector with binoculars  to safely view an eclipse indirectly.

Planet Definition Debate

If you're confused about what exactly a planet is, don't feel bad: Astronomers are still arguing over the term eight years after the International Astronomical Union (IAU) came up with a controversial new definition that demoted Pluto to "dwarf planet" status.

The Harvard-Smithsonian Center for Astrophysics (CfA) is putting on an event tonight (Sept. 18) at 7:30 p.m. EDT (2330 GMT) that could help crystallize your views. The event, which will be webcast live in the window below, is called "What Is a Planet?" and features three different experts presenting their viewpoints on the term, and on the ongoing debate.
