White-Nose Syndrome Among Bats

Little Brown Bat with White Nose Syndrome BY1556
A little brown bat (Myotis lucifugus) affected by White nose syndrome hanging at Greeley Mine in Stockbridge, Vermont. White-nose syndrome is a disease affecting hibernating bats, named for the white fungus (Geomyces destructans) that appears on the muzzle and other body parts. WNS is associated with extensive mortality of bats in eastern North America. First documented in New York in the winter of 2006-2007, WNS has spread rapidly across the eastern United States and Canada, and the fungus that causes WNS has been detected as far west as Oklahoma.

Pluto and Charon

Today is an historic day in space exploration. After a nine-year, three-billion-mile journey to the outer edge of our solar system, NASA's unmanned New Horizons spacecraft has reached Pluto. This makes the U.S. the first country to send spacecraft to every planet in our solar system.

These images of Pluto and its largest moon, Charon, were captured in the days leading up to New Horizons closest approach. Data and images gathered over the next weeks and months will reveal more about these bodies than has ever been known before.

Bumble Bees

Bumble Bee in Flight BY7124
A bumblebee (Bombus grisecollis) in flight. Bumblebees are important pollinators. As the bee sucks nectar from the flower, it rubs against the stamens - picking up grains of pollen. Each pollen grain contains a male gamete which, when deposited on another plant of the same species, can fertilize an ovule and produce seeds. Bumble bees are sociable but have relatively few members in their colonies; often fewer than 50 individuals. They feed on nectar and gather pollen for their young. They are one of the few insects able to regulate their temperature, using both solar radiation and internal cooling and warming mechanisms.

The First Warm-Blooded Fish Discovered

Opah BK3414
The Opah was the first warm-blooded fish to be discovered in May of 2015. It has a large, round body about the size of a car tire and dwells about 1,300 feet below the ocean's surface. Having warm blood allows the Opah to remain deep down in the water for longer periods of time than most other fish.

Salton Sea

BH0010 Salton Sea, Southern California
The Salton Sea, an inland saline lake in Southern California, is a haven for many different bird species. Following the extended and devastating draughts in California, much of this landscape is as dry as a desert and risks losing its bio-diversity.

Hubble Space Telescope Anniversary

Edwin Hubble

This week marks the 25th anniversary of the launch of NASA’s Hubble Space Telescope aboard the space shuttle Discovery on April 24, 1990. Orbiting at about 350 feet, with a view unobstructed by the Earth's atmosphere, the observatory has yielded 25 years of insights and spectacular images of our solar system and beyond.
