Lunar Eclipse

Astronomer Stephen Edberg captured this sequence of the full moon as it enters Earth's shadow and then is completely covered by it on August 28, 2007. The moon's passes through nearly the same portion of Earth's shadow during the total lunar eclipse on April 14-15, 2014 but the coloring may be different. A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes. When the Moon travels completely into the Earth's umbra, one observes a total lunar eclipse.

White-Nose Syndrome Among Bats

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

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. View more images of bumblebees

The First Warm-Blooded Fish Discovered

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

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. View more images of the Salton Sea

Cherry Blossoms

The cherry tree, or prunus serrulata, blossoms in Spring. The tree is native to the Himalayas but grows in temperate zones of the Nothern Hemisphere including Europe, West Siberia, South Korea, China, Japan, and the United States. View more images of Cherry Blossoms
