A total solar eclipse will darken some of Earth’s skies on Friday, but geography, weather, the economy and even the Olympics are combining to make it a hard and expensive for people to see it.The total blotting out of the sun, which occurs when the moon’s dark inner shadow falls on parts of the Earth, can only be seen in mostly remote places:
Nuclear weapons could be used to stop earth-bound asteroids, but in most instances, they are not the best option, said Apollo astronaut Rusty Schweickart during a public lecture this Wednesday in San Francisco. The scientist explained that all but the largest heavenly bodies can be redirected by rear-ending/towing them with an unmanned spacecraft.
A sample of icy soil collected by the robotic arm of NASA’s Phoenix Mars lander is apparently stuck in its scoop, foiling efforts to analyze it.
From equipment installed backwards to problems with the metric system, NASA’s failures can be as fascinating as its successes. Of course, more cynical critics might suggest that NASA’s failures overshadow its successes — but let’s see you send a ship to the moon.
This image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies.During the course of the collision,billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters.The two spiral galaxies started to interact a few 100 million years ago,making the Antennae galaxies..
Over its lifetime, NASA’s Hubble Space Telescope has captured many stunning images. Among the most memorable is this edge-on mosaic of the Sombrero galaxy. With its relatively high brightness magnitude and at a distance of 28 million light-years from Earth, Messier 104, as Sombrero is more formally known, is easily viewed through a small telescope.
A spectacular photograph snapped from NASA’s Space Shuttle Discovery during the STS-64 mission in September 1994. NASA Astronaut Mark C. Lee is floating 130 nautical miles (149.6 miles or 240.8 kilometers) above our home planet Earth. What a view!
The origin of magnetic fields in galaxies is still a mystery to astronomers. Popular theories suggest continual strengthening over billions of years. The latest results from Simon Lilly’s group, however, contradict this assumption and reveal that young galaxies also have strong magnetic fields.
World renowned UFO researcher Timothy Good tells BBC WM about the UFO sightings wave gripping Britain, the government’s secret liaisons with extraterrestrials and why a real ‘Star Wars’ might be coming.
Cosmic clouds seem to form fantastic shapes in the central regions of emission nebula IC 1805. Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula’s newborn star cluster (aka Melotte 15). About 1.5 million years young, the cluster stars appear on the right in this colorful skyscape, along with dark
