IYA2009: Closing event at the Virtual Telescope

Posted on behalf of Valentina Romeo of The Virtual Telescope:

IYA2009: Closing event at the Virtual Telescope - 400 years after the historic Galilean observations of Jupiter

• When: on Jan 7 2010 at 19.30 UT

• Where: http://www.virtualtelescope.eu

On Jan 7, 1610 Galileo Galilei pointed one of his telescopes to Jupiter, unveiling a new system of worlds, with the discovery of its bigger moons: Io, Europa, Ganymede and Callisto.

For the IYA 2009 closing ceremony at the Virtual Telescope, we decided to host a special free event on the next 7 Jan 2010, just 400 years after that revolutionary night.

We will offer a guided, live tour through the heavens, with our robotic telescopes and comments, focusing on some objects observed by Galileo.

To join, you just need to enter, on Jan 7 2010 at 19.30 UT, our website at: http://www.virtualtelescope.eu

We are looking forward to celebrate that great anniversary with you, at the very end of the International Year of Astronomy!

The official language for the event will be English.

**Feel free to invite all your friends!**

Are We Alone for 12/28/09 - Time's Mysteries Part I: Marking Time

Are We Alone - Time's Mysteries Part I: Marking Time

ENCORE: Time’s a mystery, yet we’ve invented clever ways to capture it. From sundials to atomic clocks, trace the history of time-keeping. Also, discover the surprising accuracy of nature’s dating schemes – from the decay of carbon to laying down tree rings.

Plus, why the “New York minute,” stretches to hours in Rio de Janeiro: cultural differences in the perception of time.

Guests:

• Chris Turney – Geologist at the University of Wollongong, Australia and the author of Bones, Rocks and Stars: The Science of When Things Happened
• Demetrios Matsakis – Head of the U.S. Naval Observatory’s Time Service
• Steven Jefferts – Physicist at the National Institute of Standards and Technology in Boulder, Colorado
• Robert Levine – Psychologist at California State University in Fresno and the author of A Geography of Time: The Temporal Misadventures of a Social Psychologist, or How Every Culture Keeps Time Just a Little Bit Differently
• Norman Mohr – Owner, Mohr Clocks, Mountain View, California

Are We Alone for 12/21/09 - Journey to a Black Hole

Are We Alone - Journey to a Black Hole

A massive black hole lies at the center of our galaxy, a monster hunkered down in the Milky Way’s innermost sanctum. Here, the bizarre laws of General Relativity take over, as the physics we know break down. And our spaceship is headed straight for it.

Join us on a special dramatized 26,000 light-year adventure to the Galaxy’s hulking heart of darkness. We explore a cosmos held together by gravity – discover why it’s not really a force – and try to avoid getting too close to a black hole, the ultimate expression of gravity.

This program is part of the traveling exhibit: “Black Holes, Space Warps and Time Twists,” a production of the Harvard-Smithsonian Center for Astrophysics. Find out more at:

A Big New Sunspot Emerges

Source - Space Weather News for Dec. 15, 2009: http://spaceweather.com

BIG NEW SUNSPOT: Just yesterday, sunspot 1035 was nearly invisible. Today, it is as wide as seven planet Earths. The fast-growing active region burst into view on Dec. 14th with a magnetic polarity that clearly identifies it as a member of new Solar Cycle 24. If the expansion continues apace, it could soon become the largest sunspot of the year. Check http://spaceweather.com for movies, photos and updates.

GEMINID METEOR SHOWER: This weekend, Earth will pass through a stream of debris from extinct comet 3200 Phaethon, source of the annual Geminid meteor shower. Forecasters expect more than 100 meteors per hour to fly out of the constellation Gemini when the shower peaks on Dec. 13th and 14th. For most observers, the best time to look will be from 10 pm local time on Sunday night to dawn on Monday morning. Visit http://spaceweather.com for photos, a sky map, and live audio from a meteor radar.

ASTRONOMY ALERTS FOR CHRISTMAS: Spaceweather.com's astronomy alert service makes a great gift. It works like this: Suppose the International Space Station is about to fly over your back yard. Your phone will ring and tell you to go outside and look. Subscribers also receive alerts for meteor showers, eclipses, rocket launches, Northern Lights and much more.

Stunning Spiral Light Show over Norway

Source - Space Weather News for Dec. 9, 2009: http://spaceweather.com

This morning in arctic Norway, onlookers were stunned when a gigantic luminous spiral formed in the northern sky. Veteran observers accustomed to the appearance of Northern Lights say they have never seen anything like it. It was neither a meteor nor any known form of atmospheric optics. Rumors that the spiral was caused by the botched launch of a Russian rocket have not yet been confirmed.

Visit http://spaceweather.com for images and eyewitness reports of this mysterious apparition.
