Astronomers have used the NASA/ESA Hubble Space Telescope and ESO's New Technology Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned — a surprising result given their different histories and varied properties.

MADISON, Wis. — Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet.
In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet.
Fires burned throughout Bolivia in late August. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this natural-color image on August 31, 2013.
Red outlines indicate areas where MODIS has detected high surface temperatures associated with actively burning fires. In many places, the smoke from these blazes is thick enough to completely hide the land surface below from the satellite sensor's view. In general, the smoke plumes blow toward the west and northwest.
A visible image of Tropical Storm Toraji was captured on Sept. 3 at 02:10 UTC/Sept. 2 at 10:10 p.m. is it continued moving north past eastern China and approached southern Japan. The image was taken by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite. The image showed strong thunderstorms wrapped around the center of the tropical storm. Bands of thunderstorms wrapping into the center from the north extended over Kyushu. Kyushu is the third largest island of Japan and is farthest southwest of Japan's four main islands.
A lot of things happen over a holiday weekend, and while people in the United States were celebrating Labor Day weekend, the Eastern Pacific Ocean's Tropical Storm Kiko came and went. Satellite data captured Tropical Storm Kiko's birth on Sept. 1 and saw its remnants weakening on Sept. 3. As Kiko dissipates, another low pressure system is forming near the southwestern coast of Mexico.
The Rim Fire in and around Yosemite National Park, which began on August 17, 2013 is now the fourth largest fire in California's history. According to Inciweb.org for Sept. 02, 2013: "The Rim Fire grew approximately 8,310 acres, to a total size of 231,088 acres. Burnout operations on the northern and southern portions of the fire continued with success through the night.
A precisely designed macromolecule that mimics the binding of HIV to immune system cells could be used to stop the virus from physically entering the body, according to a new study led by a materials scientist at Queen Mary University of London.
The researchers created the large molecule with several sugar molecules, known as glycopolymers. By using different sugars attached to the macromolecule in solution, the scientists were able to investigate which sugar molecules were the most effective in inhibiting the potential binding of the virus.
Inciweb.org reports, "Last night a spot fire crossed Old Yosemite Road, prompting an expansion of the Mandatory Evacuation in Mariposa County. Crews burned south from Hetch Hetchy toward Harden Lake on the eastern flank. Crews continued structure defense in the Highway 108 and 120 corridors, and around Cherry Lake. Today's operations will included actions to control the spot fire south of Old Yosemite Road.
That old "best friend" can get a bit tiresome, all that rolling over, shaking paws, long walks and eating every crumb of food off the floor. But, what if there were a way to command your dog with a remote control, or even via your smart phone...or even without hands?
LOS ANGELES — Teenagers who see friends smoking and drinking alcohol in photographs posted on Facebook and Myspace are more likely to smoke and drink themselves, according to a new study from the University of Southern California (USC).
For the first time, a dramatic global climate shift has been linked to the impact in Quebec of an asteroid or comet, Dartmouth researchers and their colleagues report in a new study. The cataclysmic event wiped out many of the planet's large mammals and may have prompted humans to start gathering and growing some of their food rather than solely hunting big game.
Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.
The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again.
NASA's Tropical Rainfall Measuring Mission or TRMM satellite flew directly above western Taiwan on August 28, 2013 at 2108 UTC when Tropical Storm Kong-Rey was dropping enormous amounts of rain. Kong-Rey is expected to affect Japan over the next several days while moving parallel to its western coastline.
Tropical Depression Juliette became post-tropical and two low pressure areas were struggling to develop in the Eastern Pacific Ocean on Aug. 30 when NOAA's GOES-West captured a beautiful panoramic image of all three systems.
Update for August 30, 2013 - The fire is over 201,00 acres as of 6 am this morning, Aug. 30, 2013 with containment at 32%. More than 40,000 acres of that fire have burned within Yosemite National Park. At least 111 structures have been destroyed by the fire, which has been burning since Aug. 17.
