NASA's TRMM Satellite calculates Hurricanes Fay and Gonzalo rainfall

The analysis showed that Gonzalo generated several areas over the Atlantic Ocean where rainfall totals topped 12 inches (300 mm). Fay's maximum rainfall was between 4 and 8 inches (100-200 mm).

This rainfall analysis showed that Gonzalo generated several areas over the Atlantic Ocean where rainfall totals topped 12 inches (red). Fay's maximum rainfall appeared between 4 and 8 inches (green).

NASA's Terra Satellite sees wind shear affecting Tropical Storm Ana

NASA's Terra Satellite sees wind shear affecting Tropical Storm Ana

Tropical Storm Ana was being battered by wind shear when NASA's Terra satellite passed overhead and saw the bulk of showers and thunderstorms pushed north and east of the center.

Organic molecules in Titan's atmosphere are intriguingly skewed

Organic molecules in Titan's atmosphere are intriguingly skewed

While studying the atmosphere on Saturn's moon Titan, scientists discovered intriguing zones of organic molecules unexpectedly shifted away from its north and south poles. These misaligned features seem to defy conventional thinking about Titan's windy atmosphere, which should quickly smear out such off-axis concentrations.

Third substantial solar flare in 2 days

Third substantial solar flare in 2 days

The sun erupted with another significant flare today, peaking at 10:28 a.m. EDT on Oct. 22, 2014. NASA's Solar Dynamics Observatory captured images of the event, which occurred in the lower half of the sun. This flare is classified as an X1.6 class flare. X-class flares denote the most extreme flares. This is the third substantial flare from the same region of the sun since Oct. 19.

NASA-led study sees Titan glowing at dusk and dawn

NASA-led study sees Titan glowing at dusk and dawn

New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.

The pair of patches was spotted by a NASA-led international team of researchers investigating the chemical make-up of Titan's atmosphere.

NASA-NOAA Suomi NPP Satellite team ward off recent space debris threat

NASA-NOAA Suomi NPP Satellite team ward off recent space debris threat

While space debris was the uncontrolled adversary in the award-winning space thriller film "Gravity," space debris, also known as "space junk," is an ongoing real-life concern for teams managing satellites orbiting Earth, including NOAA-NASA's Suomi National Polar-orbiting Partnership, or Suomi NPP, satellite. It is not unusual for satellites that have the capability of maneuvering to be repositioned to avoid debris or to maintain the proper orbit.

Two families of comets found around nearby star

Two families of comets found around nearby star

Beta Pictoris is a young star located about 63 light-years from the Sun. It is only about 20 million years old and is surrounded by a huge disc of material — a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids.

Flavien Kiefer (IAP/CNRS/UPMC), lead author of the new study sets the scene: "Beta Pictoris is a very exciting target! The detailed observations of its exocomets give us clues to help understand what processes occur in this kind of young planetary system."

New window on the early universe

New window on the early universe

Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time. The ALMA radio telescope – which stands at an elevation of 5,000 meters in the Atacama Desert of Chile, one of the driest places on earth – was then used to forge observations of the galaxy, showing how their method improves upon previous efforts.

NASA Webb's heart survives deep freeze test

NASA Webb's heart survives deep freeze test

After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Teams of engineers and technicians have been on heart-monitoring duty around the clock since this complicated assembly was lowered into the chamber for its summer-long test.

UMD researchers formulate cyber protection for supply chains

College Park, Md. - The supply chain is ground zero for several recent cyber breaches. Hackers, for example, prey on vendors that have remote access to a larger company's global IT systems, software and networks.

In the 2013 Target breach, the attacker infiltrated a vulnerable link: a refrigeration system supplier connected to the retailer's IT system.

A counter-measure, via a user-ready online portal, has been developed by researchers in the Supply Chain Management Center at the University of Maryland's Robert H. Smith School of Business.
