NASA's Terra satellite spotted the birth of Tropical Storm Vongfong in the Northwestern Pacific Ocean on Oct. 3. Vongfong is the nineteenth tropical storm of the Northwestern Pacific typhoon season.

A snaking, extended filament of solar material currently lies on the front of the sun-- some 1 million miles across from end to end. Filaments are clouds of solar material suspended above the sun by powerful magnetic forces. Though notoriously unstable, filaments can last for days or even weeks.
Luis Fernando Velásquez-García's group at MIT's Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions.
The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and "smart" textiles; or propulsion systems for fist-sized "nanosatellites."
Researchers at the University of Granada have designed a new imaging system capable of obtaining up to twelve times more colour information than the human eye and conventional cameras, which implies a total of 36 colour channels. This important scientific development will facilitate the easy capture of multispectral images in real time, and in the not too distant future it could also be used to develop new asisted vehicle driving systems, identify counterfeit bills and documents or obtain medical images much more accurate than current ones, among many other applications.
yphoon Phanfone's eye appeared the size of a pinhole on visible imagery from NASA's Aqua satellite on Oct.3.
The MODIS instrument or Moderate Resolution Imaging Spectroradiometer that flies aboard NASA's Aqua satellite captured a visible image of Phanfone moving through the Northwestern Pacific Ocean on Oct. 3 at 4:20 UTC (12:20 a.m. EDT). The tiny open eye of the storm was surrounded by a thick band of thunderstorms. The MODIS image also showed a very thick and large band of thunderstorms south of the center and spiraling into the eye.
By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, "perfect fluid" that give clues to the state of the young universe just microseconds after the big bang.
In the field experiment, the scientists set a drifting in situ chamber, called DISC, equipped with audio and video recording systems, near Fowey Rocks lighthouse in the northern Florida Keys to record larval orientation behavior in the pelagic environment. In total 58 deployments were conducted, 27 during the day and 31 at night. The team also recorded sounds in a laboratory setting to confirm that the sounds observed in the field were from gray snapper larvae.
Titan is unique in our solar system because of its dense nitrogen-methane atmosphere, which is very similar to Earth's in some ways, but very different in others. For example, air temperatures are around 200 degrees colder and, in contrast to the warm salt water seas of Earth, frigid hydrocarbon lakes populate Titan's surface.
New data obtained by NASA's GRAIL mission reveals that the Procellarum region on the near side of the moon — a giant basin often referred to as the "man in the moon" — likely arose not from a massive asteroid strike, but from a large plume of magma deep within the moon's interior.
Oceanus Procellarum, a vast dark patch visible on the western edge of the Moon's near side, has long been a source of mystery for planetary scientists. Some have suggested that the "ocean of storms" is part of a giant basin formed by an asteroid impact early in the Moon's history. But new research published today in Nature deals a pretty big blow to the impact theory.
It's old news that open-source 3D printing has a lot going for it: it's cheap, green and incredibly useful for making everything from lab equipment to chess pieces. Now it's time to add another star to the 3D printing constellation. It may help lift some of the world's most destitute people from poverty while cleaning up a major blight on the earth and its oceans: plastic trash.
At the center of the movement is a new set of standards inspired by fair trade products ranging from diamonds to chocolate.
Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 metre rise in global sea level.
The research published in Nature Communications found that in the past, when ocean temperatures around Antarctica became more layered - with a warm layer of water below a cold surface layer - ice sheets and glaciers melted much faster than when the cool and warm layers mixed more easily.
Messier 11 is an open cluster, sometimes referred to as a galactic cluster, located around 6000 light-years away in the constellation of Scutum (The Shield). It was first discovered by German astronomer Gottfried Kirch in 1681 at the Berlin Observatory, appearing as nothing more than a fuzzy blob through the telescope. It wasn't until 1733 that the blob was first resolved into separate stars by the Reverend William Derham in England, and Charles Messier added it to his famous catalogue in 1764.
"But as the minutes ticked by, the relaxed attitude of many of us began to dissolve into apprehension. Our levels of adrenaline and worry began to rise."
"The room went silent, interspersed with only an occasional murmur, all faces fixed on a noisy, fuzzy line on our computer screens."
On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded.
