Why would Mars appear to move backwards? Most of the time, the apparent motion of Mars in Earth's sky is in one direction, slow but steady in front of the far distant stars. About every two years, however, the Earth passes Mars as they orbit around the Sun.
The fact they don't -- despite spending more time looking at the sky than anyone -- is what Bad Astronomy blogger Phil Plait calls *his* favorite reason for not believing that UFOs are alien spacecraft. Plait also shares another writer's "snarky" list of Top 10 reasons not to believe. Tin-foil brigade howling in 4, 3, 2, 1 ...
Jon Edwards often manages what appears impossible. He has recovered precious data from computers wrecked in floods and fires and dumped in lakes.
Wandering through the evening sky, on May 4th planet Mars stood in line with Castor and Pollux, the two bright stars of the constellation Gemini. In this time exposure of the celestial alignment, Mars actually takes on a distinct yellowish hue, contrasting in color with Pollux; a giant star known to have a Jupiter-class planet, and Castor
Turn up your favorite Aerosmith CD, because a new report from NASA is looking at sending a two man crew to rendezvous with 2000 SG344, a 40 meter wide asteroid that was given a high chance of striking Earth.
On Tuesday, May 6, while standing on planet Earth and sweeping your binoculars along the western horizon just after sunset, you might have encountered this arresting skyscape. The view features a slender crescent Moon and bright planet Mercury separated on the sky by only about 2 degrees.
Using the unique orbit of NASA's Spitzer Space Telescope and a depth-perceiving trick called parallax, astronomers have determined the distance to an invisible Milky Way object called OGLE-2005-SMC-001. This artist's concept illustrates how this trick works: different views from both Spitzer and telescopes on Earth are combined to give depth percep
Not even NASA has done it: a collection of 6038 liftoffs since Sputnik, which celebrates its golden anniversary this fall. Explore PM's interactive time line.....

A new modular satellite platform could save NASA millions of dollars by letting them use the same basic design for a variety of unmanned missions, from Earth orbiters to moon landers to Mars orbiters. Wired.com has exclusive video of the satellite testing.
About 3.5 billion years ago, the Red Planet had extensive flowing water and then suddenly fell quiet. It didn't seem the climate had changed much since. Now, recent studies by scientists at Brown University show that Mars' climate has been much more dynamic than previously believed.
The first cyclone of the 2008 season in the northern Indian Ocean was a devastating one for Burma. According to reports from Accuweather.com, Cyclone Nargis made landfall with sustained winds of 130 mph and gusts of 150-160 mph, which is the equivalent of a strong Category 3 or minimal Category 4 hurricane.
Each time the space shuttle rises from its launchpad, a range safety officer waits anxiously for the first 2 minutes to pass safely. If the spaceship were to veer off course and endanger a populated area, this officer would bear a terrible responsibility...
· US eyes 2000SG344 for Armageddon-type mission· Rock seen as stepping stone to deep spaceThe mission - the first to what officials call a Near Earth Object (NEO) - is being floated within the US space agency as a crucial stepping stone to future space exploration.
The gegenschein is sunlight back-scattered off small interplanetary dust particles and is seen 180 degrees around from the Sun in an extremely dark sky.
"There isn't any greater potential threat to the status quo than the discovery of extraterrestrial life, which is why some people would prefer we didn't try."
The ancient catastrophe that gave birth to the Moon may have produced additional satellites that lingered in Earth's skies for tens of millions of years.
New discovery about bacteria may dramatically increase possible locations for alien life.
Tropical Cyclone Nargis as photographed on 2 May 2008 at 4:40 UTC by NASA's Terra satellite.
Japanese astronaut Takao Doi, on board of the International Space Station, has proved that a boomerang returns to the person throwing it even in the zero-gravity conditions. The idea came to him by request from his friend Yashuhiro Togai, a world boomerang champion. The result is exactly what the science behind boomerangs predicts.
No matter how quiet we try to be now it's too late to prevent alien invaders. So says Alexander Zaitsev of the Institute of Radio Engineering and Electronics in Moscow, Russia, who points the finger at astronomers. "We are all doomed!..." Somebody shouted.
The Johns Hopkins University Applied Physics Laboratory is sending a spacecraft closer to the sun than any probe has ever gone ? and what it finds could revolutionize what we know about our star and the solar wind that influences everything in our solar system.
NASA is opening the door to anyone wanting to go to the moon as part of their next lunar mission?all without requiring years of tests, training, or smoking astroturf. Sadly, only your name will go. You will get a certificate from NASA.
"Although the day started with difficulties, it ended with a successful 1000 foot space elevator test climb to a tethered 10-foot diameter balloon - LiftPort's first really significant climb. This was supposed to be a 1 mile climb test, but the FAA-required aviation orange paint - applied at 50 foot intervals to the ribbon - contained acetone,
