Astronomers find youngest supernova remnant in the Milky Way
An international team of astronomers has found the youngest known supernova remnant in the Milky Way Galaxy. Using observations made with the Very Large Array (VLA) radio telescope in the United States and the orbiting Chandra X-ray observatory, the scientists report that the remnant, G1.9+0.3, is 150 years old … Read more.

Antennae Galaxies move closer
The Antennae Galaxies are among the closest known merging systems. Also known as NGC 4038 and NGC 4039, the two began interacting a few hundred million years ago, creating one of the most impressive sights in the night sky. They are used by scientists as a standard against which to validate theories of galactic evolution … Read more.

“I love astronomy. And the Davis Mountains in the Big Bend region of Texas have some of the finest night sky anywhere in the country. That’s why we bought our 20 acres at Sierra La Rana.”
Experience the high desert skies of Sierra La Rana. With an elevation of nearly 5,000 feet above sea level, we have moderate winters and temperate summers. Our location at 30º north latitude means we are farther south than most of the southwest. Located near the world-famous University of Texas McDonald Observatory and Texas Star Party, we have dark-sky-friendly lighting ordinances. We are close to excellent medical and educational facilities and Sul Ross State University. You also will find abundant outdoor recreational activities, such as hiking, birding, horseback riding, and photography.
Learn more about Sierra La Rana and amazing home sites with dramatic views of the Davis Mountains. |

Ruddy Mars shines at 1st magnitude, equaling the nearby giant star Pollux. The Red Planet then lies approximately 150 million miles from Earth, so it measures a mere 5.8″ across. You’ll need a 10-inch or larger telescope to see any appreciable detail.
The best most of us can do is to watch its trek against the background stars.
On May 21, Mars lies on the western edge of the Beehive star cluster (M44). The following 2 nights, Mars passes through the cluster. Grab your binoculars May 22 and 23 for a great view. This conjunction also offers the opportunity to take some fine close-up photographs. Mars shines nearly 2 magnitudes brighter than the combined output of the Beehive’s few hundred stars. |

Astronomy magazine will present its annual $2,500 Out-of-this-world award to an astronomy club or organization for excellence in astronomy outreach activities. The award focuses on ongoing public programming - not one specific event - conducted by any educational or civic organization.
The prize will reward a group’s sustained efforts to involve its local community in the science and hobby of astronomy, and will be awarded for use in future public programs.
All entries must be postmarked by July 18, 2008.
Find out how your group can enter.

Russia: Siberian Total Solar Eclipse and Grand Waterways of the Czars,
July 18-August 2, 2008
The Astronomy Siberian eclipse tour begins with a journey from St. Petersburg to Moscow in comfort and style aboard the river vessel Viking Kirov. Next, the group will fly to Novosibirsk, Siberia, for the total solar eclipse. The tour also will stop in forested villages and quaint towns. Plus, we’ll see grand monuments, opera houses, opulent palaces, fortified monasteries, and beautiful cathedrals along the waterways.
Listen to Astronomy Editor Dave Eicher and MWT Associates’ Melita Thorpe talk about the trip’s highlights.

NASA engineers propose to get up close and personal with an asteroid
|
I’m happy to report NASA may be planning to do more about the as-yet unaddressed asteroid threat to Earth than helplessly watch giant space rocks whiz by the home planet from time to time. The Guardian, a British newspaper, reported recently that some NASA scientists have written a report outlining a mission to asteroid 2000SG344. The object is about 130 feet (40 meters) wide. It last passed close by Earth in 2000 and will return for another try in September 2030.
2000SG344 is one of scores of asteroids, dubbed near-Earth objects (NEOs), that could someday collide with the planet. NASA’s ongoing Constellation program should make an NEO mission possible with completion of the Orion crew vehicle and the Ares I and Ares V launchers …
