THE DESCENT OF PHOENIX: When NASA's Phoenix probe parachuted to Mars last Sunday, a pair of other spacecraft were orbiting high overhead, watching and listening. While NASA's Mars Reconnaissance Orbiter snapped some jaw-dropping photos of Phoenix's plunge to the surface, Europe's Mars Express orbiter recorded Phoenix's radio transmissions. The eerie-sounding tones have just been beamed back to Earth and you can listen to them by following the links at today's edition of http://spaceweather.com.
CARTWHEEL CME: Imagine a billion-ton cloud of gas launching itself off the surface of the sun and then ... doing a cartwheel. That's exactly what happened on April 9, 2008, when a coronal mass ejection pirouetted over the sun's limb in full view of an international fleet of spacecraft. The cartwheel set off a chain of events that amazed even veteran solar physicists. The full story, and a spectacular movie of a second cartwheel recorded just last week, may be found at http://spaceweather.com

NASA astronomers have been watching the Moon to see how often meteoroids crash into the lunar surface and they've just video-recorded their 100th explosion. This surprisingly bountiful data-set allows researchers to start drawing conclusions about when, where, and how often the Moon gets hit.

GLOBAL SATELLITE TRACKING: Spaceweather.com's simple Satellite Tracker has gone global. The tool now works not only for US and Canadian readers, but also for sky watchers in countries around the world. This development comes as the International Space Station is making bright and frequent nightly apparitions over Europe, Africa, the Middle East, parts of Asia and Australia. If you live in those areas, give it a try: http://spaceweather.com/flybys
POLLEN CORONAS: Warning, this story may make you sneeze. Swarms of springtime pollen in the northern hemisphere are drifting in front of the sun and making multi-colored coronas (rings of light) in the sky. Unlike circular coronas caused by water droplets in clouds, pollen coronas have strange elliptical shapes dotted by colorful bright patches. Pictures featured on today's edition of http://spaceweather.com show you what to look for.

Space Weather News for May 7, 2008

NOCTILUCENT CLOUDS: On May 5th, experienced sky watchers in Northern Ireland were surprised by a sudden apparition of electric-blue noctilucent clouds (NLCs). This marks an unusually early beginning to the 2008 NLC season and may herald a spectacular summer of high-latitude "night shining" clouds. NLCs first appeared in the 19th century mainly around Earth's poles. Since then, for reasons unknown, they have increased in number and range, with sightings in recent years as far south as Utah and Colorado. Visit http://spaceweather.com to see the first photos of 2008 and to learn what to look for in case NLCs visit your part of the world in the nights ahead.
===============================================
The sky this month
Mars joins M44
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. Luckily, Mars has a few good companions this month: A waxing Moon stands 6° to its west May 9, just 4 days after the planet crossed into Cancer. The following night, the Moon stands a similar distance east of the planet.
The best is yet to come. 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.

NASA Science News for May 6, 2008
In September 1859, the sun unleashed a solar flare so intense it was visible to the unaided human eye. A ferocious geomagnetic storm ensued in which Northern Lights descended as far south as Cuba, the Bahamas and Hawaii. Meanwhile, telegraph engineers disconnected their batteries and powered communications by electricity from the auroras! Could it happen again? Read today's story to find out.

Too bad I can't view the meteor shower tonight. Though I did check the sky out last night. I saw 8 per hours. Not bad.... Good luck wherever you are at. Enjoy stargazing sky! :)

AQUARID METEOR SHOWER
Space Weather News for May 4, 2008
http://spaceweather.com
ETA AQUARID METEOR SHOWER: If you see a meteor flit across the sky tonight, it could be a piece of Halley's Comet. Earth is crossing a stream of dusty debris from Halley and this is causing the annual eta Aquarid meteor shower. Sky watchers in the tropics and southern hemisphere (where the shower is most intense) could see as many as 70 meteors per hour during the dark hours before dawn on Monday, May 5th, and Tuesday, May 6th. The show is diminished at northern latitudes where rates may be 15 meteors per hour or less. Check http://spaceweather.com for sky maps and more information.
MERCURY AND THE MOON: Innermost planet Mercury is emerging from the glare of the sun and putting on its best show of the year. A good time to look is Tuesday evening, May 6th, just after sunset when the crescent Moon glides by Mercury in the darkening western sky. A sky map and photos are available at http://spaceweather.com.

FLYBY ALERT: This is a good month for spaceship spotting. On May 1st, the International Space Station (ISS) begins a 4-week series of bright flybys over North America and Europe. In early May, the ISS joins Jupiter and the stars of the Summer Triangle in a glittering pre-dawn sky. Later in the month, increasingly-frequent flybys shift to evening hours and the ISS will be crossing paths with Saturn, the Moon and Mars. US and Canadian readers, check our Simple Satellite Flybys tool to find out when to look: http://spaceweather.com/flybys . (European readers, an international version of the flybys tool will be available in the near future. Stay tuned.)
EXPLORE THE IONOSPHERE: The ionosphere is our planet's "final frontier." A realm of dancing auroras, radio-bending plasma bubbles and dangerous ultraviolet rays, it is the last wisp of Earth's atmosphere that astronauts leave behind when they enter space. Now you can explore the ionosphere from the safety of your own home. Yesterday, NASA-supported researchers unveiled a "4D" computer model for the general public. Download a few files and presto--you're flying through the ionosphere. The model shows the ionosphere as it is right now; it's a real-time display based on current solar activity and atmospheric conditions. Visit http://spaceweather.com to get started.
