The volcano on the Eyjafjallajokull glacier in southern Iceland began erupting just after midnight on April 15.
Icelandic public broadcaster RUV reported that a 500m fissure appeared at the top of the crater today.
Lava melted the glacier, causing major flooding which forced the evacuation of between 700 and 800 people from their homes in the remote, lightly populated area … Read the rest of this article
After months of inactivity, I finally got around to plugging the SynScan hand controller into the EQ6 and powering everything up. No bangs, flashes or fizzles with trails of wispy smoke! Everything worked.
I used to use a car battery to power my old Skysensor 2000/GP DX mount but I bought an Observatory Power Supply to use with the EQ6 … Read the rest of this article

A NASA spacecraft gliding over the surface of Mercury has revealed that the planet’s atmosphere, the interaction of its surrounding magnetic field with the solar wind, and its geological past display greater levels of activity than scientists first suspected. The probe also discovered a previously unknown large impact basin about 430 miles in diameter — equal to the distance between … Read the rest of this article
So you thought Northern Lights were big in Alaska? “That’s nothing,” says Randy Gladstone of the Southwest Research Institute in San Antonio, Texas. “Jupiter has auroras bigger than our entire planet.”
Last month, Gladstone and colleagues used NASA’s Chandra X-ray Observatory to capture the picture above.
The purple ring traces Jupiter’s X-ray auroras. Gladstone calls them “Northern Lights on steroids. … Read the rest of this article
April 14, 2010: NASA’s Cassini spacecraft has captured images of lightning on Saturn. The images have allowed scientists to create the first movie showing lightning flashing on another planet.
After waiting years for Saturn to dim enough for the spacecraft’s cameras to detect bursts of light, scientists were able to create the movie, complete with a soundtrack that features the … Read the rest of this article
A comprehensive analysis of distorted galaxies from the most ambitious cosmic survey ever undertaken by the Hubble Space Telescope has confirmed the mysterious cosmic acceleration. It has also provided the equivalent of a 3D map of part of the Universe.
A group of astronomers, led by Tim Schrabback of Leiden Observatory, conducted an intensive study of more than 446,000 galaxies … Read the rest of this article
A crew of six, including two Europeans, will soon begin a simulated mission to Mars in a mockup that includes an interplanetary spaceship, Mars lander and martian landscape. The Mars500 experiment, as long as a real journey to Mars, is a test of human endurance.
Their mission is to mimic a full mission to Mars and back as accurately as … Read the rest of this article
