A Superwind from the Cigar Galaxy

What's lighting up the Cigar Galaxy? M82, as this irregular galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81. This doesn't fully explain the source of the red-glowing outwardly expanding gas, however. Recent evidence indicates that this gas is being driven out by the combined emerging particle winds of many stars, together creating a galactic "superwind." The above recently released photograph from the new Subaru Telescope highlights the specific color of red light strongly emitted by ionized hydrogen gas, showing detailed filaments of this gas. The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in infrared light, and can be seen in visible light with a small telescope towards the constellation of Ursa Major.

Sojourner On Mars

The six wheeled robot rover Mars Sojourner rolled onto the martian surface on July 5th (Sol 2) at about 10:40 PM Pacific Daylight Time. This image confirms that its descent down the lander's rear deployment ramp was successful. Click on the image to download a "movie gif" constructed from 9 images taken by the Sagan Memorial Station's IMP camera which shows the rover rolling down the ramp! The rover moved only a short distance from the ramp and spent the night analyzing the martian soil with its Alpha Proton X-Ray Spectrometer. Its next destination will be a tantalizing rock about 1 foot away that scientists have named "Barnacle Bill". A slow but steady off-road vehicle powered by a 1.9 square foot solar array, the rover can negotiate obstacles tilted at a 45 degree angle and travels at less than half an inch per second or nearly 0.03 miles per hour.

Venus Unveiled

The surface of Venus is perpetually covered by a veil of thick clouds and remains hidden from even the powerful telescopic eyes of earth-bound astronomers. But in the early 1990s, using imaging radar, the Venus orbiting Magellan spacecraft was able to lift the veil from the face of Venus and produced spectacular high resolution images of the planet's surface. Colors used in this computer generated picture of Magellan radar data are based on color images from the surface of Venus transmitted by the Soviet Venera 13 and 14 landers. The bright area running roughly across the middle represents the largest highland region of Venus known as Aphrodite Terra.
