Astro-Vid Of the Week: To The Asteroids & Beyond

We never miss a chance to catch the fascinating series of talks posted weekly on YouTube via the SETI Institute. Beyond just aliens, these thought expanding seminars cover the length and breadth of space science. Often, the talks are highly technical, but we almost always grab something out of even the advanced ones. [Read more...]

A mission to a Near-Earth Asteroid will be unlike any other that NASA has undertaken to date. Gravity will be negligible, and astronauts will have to work in an unknown environment far from Earth. To this end, NASA has begun set-up earlier this week of an exciting new project off of the Florida Keys. [Read more...]

Ever wondered what local space would be like if the Earth had more than one moon? Well, it turns out that we do have several natural interlopers; sort of. Recently, researchers A.A. Christou and D. J. Asher of Armagh Observatory in Northern Ireland reported on the discovery of a unique Near-Earth Asteroid (NEA): 2010 SO16, a 200-400 meter space rock locked in a horse-shoe orbit with Earth.

28.02.11: Pan-STARRS Sets a New Record.

While you were sleeping on the night of January 29th, 2011, astronomers both human and cyber atop Haleakala in Hawaii were on patrol. The telescope was the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), and the quarry was Near Earth Asteroids (NEAs). In one marathon night, astronomers Richard Wainscoat, David Tholen and Marco Micheli of the University of Hawaii’s Institute for Astronomy bagged 19 confirmed NEAs, the most discovered in a single run.

An orbiting sentinel recently completed its secondary science mission. WISE, NASA’s Wide-field Infrared Survey Explorer, recently completed an all sky survey for Near Earth Objects (NEOs). Launched in December 2009, WISE’s primary mission was an all sky survey in the infrared spectrum. [Read more...]

11.12.10: The “Quasi-Moon” of Venus.

The curious orbit of 2002 VE68. (Created with JPL’s Ephemeris Generator).

   Up until about the mid-19th century, astronomers reported spurious sightings of a moon near our sister world, Venus. These sightings were copious enough to even warrant a name, Neith. Today, most of these observations have gone the way of the Vulcan’s and second Moon of Earth sightings as curiosities, chalked up to background stars or internal reflections in antique optics. Venus has no moon… but an interesting asteroid may vie for the next closest thing.
