Tracking a gigantic sunspot across the Sun

Tracking a gigantic sunspot across the Sun

An active region on the sun – an area of intense and complex magnetic fields – rotated into view on Oct. 18, 2014. Labeled AR 12192, it soon grew into the largest such region in 24 years, and fired off 10 sizable solar flares as it traversed across the face of the sun. The region was so large it could be seen without a telescope for those looking at the sun with eclipse glasses, as many did during a partial eclipse of the sun on Oct. 23.

NASA sees remnants of Nilofar go to cyclone graveyard

NASA sees remnants of Nilofar go to cyclone graveyard

Wind shear has caused the demise of former Tropical Cyclone Nilofar in the northern Arabian Sea. NASA's Aqua satellite passed over Nilofar on Oct. 31 and captured an image that shows strong wind shear has pushed the bulk of clouds and showers away from Nilofar's center, basically sending the storm to its grave.

A new generation of storage -- ring

A new generation of storage -- ring

A bright synchrotron source that emits over a wide part of the electromagnetic spectrum from the infrared to hard X-rays is currently being built in Lund, Sweden. The MAX IV facility presents a range of technical challenges for the team putting together its component parts in a storage - ring synchrotron system that will have a circumference of just a few hundred metres. Nevertheless, if these various challenges can be addressed then an entirely new class of experiments that require source brightness and transverse coherence will be possible.

Tropical Depression Nuri now haunting the western Pacific Ocean

Tropical Depression Nuri now haunting the western Pacific Ocean

Tropical Depression Nuri formed on Halloween morning, October 31, and is haunting the waters of the western North Pacific Ocean. NASA-NOAA's Suomi NPP satellite captured a ghostly-white image of the storm.

Tropical Storm Vance's center looks like a pumpkin to NASA's Terra satellite

Tropical Storm Vance's center looks like a pumpkin to NASA's Terra satellite

Tropical Depression 21E strengthened overnight on Oct. 30 and by Halloween morning, Tropical Storm Vance was haunting the waters of the Eastern Pacific Ocean. In a false-colored infrared image from NASA's Terra satellite on Oct. 31, the strong thunderstorms around the center resemble a pumpkin.

Tropical Depression 21E formed on Oct. 30 after struggling for days as a low pressure area. Just a day later it strengthened into a tropical storm and was renamed Vance.

Hubble sees 'ghost light' from dead galaxies

Hubble sees 'ghost light' from dead galaxies

NASA's Hubble Space Telescope has picked up the faint, ghostly glow of stars ejected from ancient galaxies that were gravitationally ripped apart several billion years ago. The mayhem happened 4 billion light-years away, inside an immense collection of nearly 500 galaxies nicknamed "Pandora's Cluster," also known as Abell 2744.

New study finds oceans arrived early to Earth

New study finds oceans arrived early to Earth

Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet's surface and are home to the world's greatest diversity of life. While water is essential for life on the planet, the answers to two key questions have eluded us: where did Earth's water come from and when?

Goodbye to rainy days for US, Japan's first rain radar in space

After 17 years of groundbreaking 3-D images of rain and storms, the joint NASA and Japan Aerospace Exploration Agency Tropical Rainfall Measuring Mission (TRMM) will come to an end next year. NASA predicts that science operations will cease in or about April 2015, based on the most recent analysis by mission operations at NASA's Goddard Space Flight Center, Greenbelt, Maryland.

Fun and games make for better learners

Four minutes of physical activity can improve behaviour in the classroom for primary school students, according to new research by Brendon Gurd.

A brief, high-intensity interval exercise, or a "FUNterval," for Grade 2 and Grade 4 students reduced off-task behaviours like fidgeting or inattentiveness in the classroom.

Captive rhinos exposed to urban rumbles

WASHINGTON, D.C., October 31, 2014 -- The soundtrack to a wild rhinoceros's life is wind passing through the savannah grass, birds chirping, and distant animals moving across the plains. But a rhinoceros in a zoo listens to children screaming, cars passing, and the persistent hum of urban life.
