Asteroid 2003 UV11 will fly past Earth on Oct. 29th and 30th (2010) at a distance of only 1.2 million miles. Its minimum (closest) approach to Earth happens at 02:24:00 Greenwich Mean Time (GMT) on October 30th.
Experienced amateur astronomers should have little trouble photographing the 600-meter wide space rock as it glides through the constellation Pegasus on Friday night, … Read the rest of this article
| The SLOOH Interface |
SLOOH is a robotic observatory on the Canary Islands. Every Monday, whenever conditions permit viewing, you can participate in multiple SLOOH “missions” over the course of an hour-long session.
What does SLOOH stand for? Apparently it’s about putting the OOH into SLEW!
High atop Mount Teide, on Tenerife in the Canary Islands, the telescopes of SLOOH stand … Read the rest of this article
This month, Comet Hartley 2 has put on a good show for backyard astronomers. The comet’s vivid green atmosphere and auburn tail of dust look great through small telescopes, and NASA’s Deep Impact/EPOXI probe is about to return even more dramatic pictures when it flies past the comet’s nucleus on Nov. 4th.

A few weeks back, I did a test run with the LVI Smartguider. I mounted the LVI in the eyepiece holder of the 80mm refractor that I’m using a guide scope. This is mounted on my Vixen 8″ reflector and the whole setup is driven by an EQ6 mount.
I attached my Canon 350D to the Vixen 8″ (200mm) … Read the rest of this article
Nearly a year after announcing the discovery of water molecules on the moon, scientists have revealed new data uncovered by NASA’s Lunar CRater Observation and Sensing Satellite, or LCROSS, and Lunar Reconnaissance Orbiter, or LRO—and it’s more than just water.

For backyard stargazers, the next few nights are the best time to see green Comet 103P/Hartley 2 as it approaches Earth for an 11-million-mile close encounter on Oct. 20th.
The dark hours before dawn are the best so set your alarm clock, go outside, and look straight up. Comet Hartley 2 is not far from the bright star Capella in … Read the rest of this article

Volcanic cones along lava path |
Scientists are crediting satellite imagery with helping to predict where volcanic eruptions could strike. It is well known that earthquakes can stress Earth’s crust and trigger subsequent quakes, but there has been no proof of this for volcanoes until now.
In September 2005, a volcanic event in Ethiopia’s Afar Desert forced magma up through rocks … Read the rest of this article
