NASA officials will host a webcast featuring the Orionid meteor shower tonight (Oct. 19) starting at 10 p.m. EDT (0200 Oct. 20 GMT) from the space agency's Marshall Space Flight Center in Alabama. You can watch the webcast live in the window below:
The Orionid meteor shower occurs annually when Earth passes through dust left behind by the famed Halley's Comet. Stargazers should expect to see about 20 meteors per hour in the wee hours of Tuesday (Oct. 21) morning, depending on light pollution and weather conditions, according to NASA.
Even if the meteor shower itself doesn't meet expectations, NASA's webcast could still provide some interesting views of the night sky:
"The display will be framed by some of the prettiest stars in the night sky," NASA officials said in a statement. "In addition to Orionids, you'll see the Dog Star Sirius, bright winter constellations such as Orion, Gemini and Taurus, and the planet Jupiter. Even if the shower is a dud, the rest of the sky is dynamite."
The Slooh Community Observatory will also host an Orionid meteor shower webcast on Tuesday (Oct. 21) starting at 8 p.m. EDT (0000 Oct. 22 GMT). You can watch the webcast directly through Slooh, or view it live in the window below:

Comet Siding Spring's Flyby of Mars Webcasts
(UPDATE: The first Slooh webcast has ended. The next event will begin at 8:30 pm ET.)The Slooh Community Observatory will broadcast a double feature about Comet Siding Spring's close pass by Mars today (Oct. 19). The first Slooh webcast will start at 2:15 p.m. EDT (1815 GMT), and the second will begin at 8:30 p.m. EDT (0030 Oct. 20 GMT). Full Story: Comet Buzzes Mars in Once-in-a-Lifetime Flyby . You can watch the webcasts live in the window below:
Comet Siding Spring is due to make a close pass with the Red Planet, flying only 87,000 miles (139,500 kilometers) from Mars. Officials monitoring spacecraft orbiting Mars are maneuvering them into safe positions so that they will not experience any ill affects from the icy wanderer's dust.
The Virtual Telescope Project will also host a webcast on Oct. 19 starting at 12:45 p.m. EDT (1645 GMT). You can watch the webcast here: http://www.virtualtelescope.eu/webtv/ A window of the webcast will appear below before the start time as well.
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.
REPLAY: Solar Storm Webcast, Sept. 11: To see our latest story on the solar storm effects on Earth last week, visit: Back-to-Back Sun Storms May Supercharge Earth's Northern Lights
The online Slooh Community Observatory will host a free webcast on Thursday, Sept. 11, to provide live views of the active sunspot AR2158, which unleashed a massive X1.6 solar flare on Wednesday (Sept. 10). The webcast will begin at 1 p.m. EDT (1700 GMT). You can watch it live on the Slooh website (http://www.slooh.com) and in the window below:
X-class solar flares are the most powerful type of storms on the sun. The Slooh webcast will feature live views of AR2158 from a solar telescope at the Prescott Observatory in Prescott, Arizona. Slooh host Geoff Fox, astronomer Bob Berman and Prescott Observatory owner Matt Francis will provide live commentary during the webcast. Viewers can submit questions via Twitter using the hashtag #Sloohflare. Sun Unleashes Major Solar Flare at Earth
"What solar experts fear most is a recurrence of the huge coronal mass ejection events of 1921 and 1859. A government-sponsored panel in 2008 estimated that such a solar event today would likely destroy the U.S. electrical grid, inflict a staggering $1 to $2 trillion dollars worth of damage, and require over a year to repair," Berman said. "So it's more than of mere academic interest to monitor and observe these violent events as they unfold. Plus, they're amazing to watch."
September Harvest Moon Replay
The Slooh Community Observatory will host a webcast featuring live views of the 2014 full Harvest Moon tonight (Sept. 8) at 9:30 p.m. EDT (0130 Sept. 9 GMT). The full moon that rises closest to the September equinox is deemed the Harvest Moon. This moon is also special because it is the third in a series of "supermoons" - full moons that rise when the moon is at its closest point to Earth in its orbit. You can watch the webcast from Slooh in the window below:

From Slooh: "Whether we call this a super Harvest Moon or a Harvest supermoon, and whether we fuss over the fact that lunar perigee happened just one night before this moon was full, there's no denying that it's the Harvest Moon," Slooh astronomer Bob Berman said in a statement. "This is the year's most famous full moon, and one of only two that even have a name. Yet it's bathed in myth and misconception even without all the extra 'supermoon' business. It will be fun to explore the true secrets of the Harvest Moon while watching it live."

Replay: Slooh 'Supermoon' Webcast
The online Slooh Community Observatory will host a webcast about the supermoon on Sunday (Aug. 10) starting at 7:30 p.m. EDT (2330 GMT). Slooh representatives will discuss this month's full moon, the biggest of 2014. Latest Story: Is Sunday's Supermoon Full Moon Really That Super? The moon is going to turn full phase at perigee - the point in its orbit when the natural satellite is closest to Earth. You can watch the webcast in the window below or directly through Slooh:
"Nothing in the sky is more striking than the rising of an enormous-looking full moon," Slooh astronomer Bob Berman said in a statement. "And this will be largest since March, 2011. And although the size-enhancement is 11 percent compared to an apogee full moon like the the one this past January, it will seem even larger -- much larger -- thanks to the psycho-optical effect we will discuss during the show. And, thanks to the super-tides that day and the following day, Earth’s biosphere will definitely be affected by this event."

The online Slooh Community Observatory offered live views of the annual Delta Aquarid meteor shower on Monday night (July 28) and you can relive the webcast live via Slooh.com and here on this page. The webcast, which will be followed Tuesday by a NASA meteor webcast, will begin at 10 p.m. ET (7 p.m. PT/0200 GMT) and feature commentary from Slooh experts. Full Story: Don't Miss These Minor Meteor Showers This Summer
The Slooh Community Observatory webcast will feature a live video stream of the peak of the Delta Aquarids from the Institute of Astrophysics, Canary Islands and the Prescott Observatory in Arizona. Slooh astronomer Bob Berman will provide audio commentary during the event. Viewers can also follow the meteor shower webcast on Twitter with the hashtag #SloohShower.
Slooh will be using a new super-sensitive low-light equipment to enhance its meteor views from the Canary Islands, courtesy of the Prescott Observatory, Slooh representatives said in a statement.
"The results obtained by this new equipment are what's primarily fascinating," Berman said. "We're hoping to capture more meteors than ever before, despite the modest nature of this relatively little-known shower."
Berman said that the origins of the Delta Aquarid meteor shower thought to be the Comet Macholtz, which was discovered in 1986, but it is not known for sure. "The slightly mysterious nature of these often-overlooked shooting stars adds to the night's fun."
