NASA's Fermi finds a 'Transformer' pulsar

NASA's Fermi finds a 'Transformer' pulsar

"Astronomers have long suspected millisecond pulsars were spun up through the transfer and accumulation of matter from their companion stars, so we often refer to them as recycled pulsars," explained Anne Archibald, a postdoctoral researcher at the Netherlands Institute for Radio Astronomy (ASTRON) in Dwingeloo who discovered J1023 in 2007.

Carlton Fire Complex, Washington -- July 22, 2014

Carlton Fire Complex, Washington -- July 22, 2014

The Carlton Complex fires started on July 14, 2014, by lightning from a weather system that moved through the Methow Valley. The Carlton Complex consists of four fires: Stokes Fire, Gold Hikes Fire, French Creek Fire and the Cougar Flat. The Stokes and Gold Hikes fires are now one larger fire. The fires are burning in timber and grass and the area burning is currently over 243,000 acres in size. The present fire situation continues to rapidly change due to the high fire danger. Public and firefighter safety is the priority on the Carlton Complex fires.

NASA's TRMM satellite measured up Super Typhoon Rammasun's rainfall rates, rainfall totals and cloud heights providing a look at the inner workings and aftermath of the storm.

Super Typhoon Rammasun struck the southern coast of China on Friday, July 18 as a very powerful super typhoon with sustained winds estimated at 135 knots (~155 mph or equivalent to a Category 5 hurricane on the US Saffir-Simpson scale), making it the strongest typhoon to hit the area in several decades.

NASA's Aqua satellite gets infrared hint on Tropical Depression 2

NASA's Aqua satellite gets infrared hint on Tropical Depression 2

Infrared data gathered on the tropical low pressure area known as System 92L gave forecasters a hint that the low would become the Atlantic Ocean hurricane season's second tropical depression.

Fires and smoke in Canada's Northern Territories

Fires and smoke in Canada's Northern Territories

Environment Canada has issued a high health risk warning for Yellowknife and surrounding area because of heavy smoke in the region due to forest fires. Currently 160 wildfires are burning across the region. There are no plans for evacuation since these fires are endangering people or property. Weather that has been hitting the area recently comes with mixed results. The rains help to dampen the fires, but the lightning tends to start others.

Hubble traces the halo of a galaxy more accurately than ever before

Hubble traces the halo of a galaxy more accurately than ever before

Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.

Bats use polarized light to navigate

Scientists have discovered that greater mouse-eared bats use polarisation patterns in the sky to navigate – the first mammal that's known to do this.

The bats use the way the Sun's light is scattered in the atmosphere at sunset to calibrate their internal magnetic compass, which helps them to fly in the right direction, a study published in Nature Communications has shown.

Despite this breakthrough, researchers have no idea how they manage to detect polarised light.

'Moral victories' might spare you from losing again

It's human nature to hate losing.

Unfortunately, it's also human nature to overreact to a loss, potentially abandoning a solid strategy and thus increasing your chances of losing the next time around.

That's one conclusion of a Brigham Young University study published this week by the journal Management Science. The finding is based on an analysis of two decades of data on NBA coaching decisions.
