From Slooh: "On the the evening of February 19th from North America, Slooh will welcome in the Lunar New Year with a live show, celebrating the astronomy of this special day. This will include never-before-seen images of the New Moon taken by the Dubai Astronomy Group, and a timed zodiacal challenge for both viewers and on-air hosts alike, based on live imagery from Slooh observatories at the Institute of Astrophysics, Canary Islands (IAC) and Pontificia Universidad Católica De Chile (PUC)!"

WEBCAST REPLAY: 'State of the Universe'

Leading cosmologist Kendrick Smith will give a "state of the universe address" tonight (Feb. 4), and you can watch it online in the window below beginning at 7 p.m. EST (0000 GMT Feb. 5):

Smith, a researcher at the Perimeter Institute for Theoretical Physics in Canada, will discuss our current knowledge of the universe and its evolution, as well as the questions that keep cosmologists like him busy every day. His talk is called "Cosmology in the 21st Century."

From the Perimeter Institute: "Smith will take the audience on a journey of discovery through the expanding universe, from the Big Bang to our present-day understanding of dark matter and other cosmic phenomena. He will explore the yet-unsolved mysteries of the universe, and explain how new research aims to shed light on these deep questions."

Tonight's talk is part of the Perimeter Institute's public lecture series. You can watch it live directly via the Institute as well:

REPLAY: The online Slooh observatory offered a free webcast Thursday (Jan. 29) at 5:30 p.m. EST (2230 GMT) to track Comet Lovejoy as it makes its closest approach to the sun. You can watch a replay of the show in the window below: 

From Slooh astronomer Will Gater: "Comet C/2014 Q2 Lovejoy has been putting on a spectacular show in our night skies with its ethereal tail and glowing coma. Slooh Slooh’s members have been watching it right from the early days after its discovery, capturing images of its evolution and development from a distant fuzzball to the beautiful comet we’re seeing today. Now, as it reaches perihelion, we’ll be looking back at the comet’s incredible journey so far and finding out what Slooh’s powerful telescopes are seeing right now."

From NASA: "The asteroid will safely pass about three times the distance of Earth to the moon, or approximately 745,000 miles (1.2 million kilometers) from Earth. Scientists have been tracking the path of the asteroid for 11 years and know its orbit well. Asteroid 2004 BL86 will not approach Earth this close again for at least 200 years. This is a rare opportunity for observation. Hope you will join us as we observe the flyby."

Slooh Webcast

The online Slooh observatory offered a free webcast today (Jan. 26) at 11 a.m. EST (1600 GMT) to track the mountain-sized asteroid 2004 BL86. You can watch the webcast replay on the website, or in the window below. A full story on the flyby and NASA's science campaign will be posted today.

From Slooh: "Slooh will cover the flyby of Asteroid 2004 BL86 live on Monday, January 26th starting at 8:00 AM PST / 11:00 AM EST / 16:00 UTC - International Times: Slooh will broadcast the event live from telescopes situated in Australia. Viewers can watch the live asteroid webcast free on The image stream will be accompanied by discussions led by Slooh host Will Gater, Slooh astronomer Bob Berman, and special guests including Dr. Paul Chodas, manager of JPL'S Near-Earth Object Program Office, and Dr. Lance Benner, NASA Research Scientist. Viewers can follow updates on the show and ask questions to be answered live on air by using the Twitter hashtag #SloohBL86."

In addition to the Slooh webcast, the Italy-based Virtual Telescope Project will offer a second free webcast at 2:30 p.m. EST (1930 GMT), with astrophysicist Gianluca Masi overseeing the event.

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."

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.
