The case of the vanishing honeybees

In the past decade, the US honeybee population has been decreasing at an alarming and unprecedented rate. While this is obviously bad news for honeypots everywhere, bees also help feed us in a bigger way — by pollinating our nation’s crops. Emma Bryce investigates potential causes for this widespread colony collapse disorder.

Hubble’s Stunning Monkey Head Nebula

Astronomers using the Hubble Space Telescope have captured infrared-light images of a churning region of star birth 6,400 light-years away. New from Hubblecast.

The collection of images reveals a shadowy, dense knot of gas and dust sharply contrasted against a backdrop of brilliant glowing gas in the Monkey Head Nebula (also known as NGC 2174).

The image demonstrates Hubble’s powerful infrared vision and offers a tantalizing hint of what scientists can expect from the upcoming James Webb Space Telescope. Observations of NGC 2174 were taken in February, 2014.

Massive newborn stars near the center of the nebula (and toward the right in this image) are blasting away at dust within the nebula. The ultraviolet light emitted by these bright stars helps shape the dust into giant pillars.

This carving action occurs because the nebula is mostly composed of hydrogen gas, which becomes ionized by the ultraviolet radiation. As the dust particles are warmed by the ultraviolet light of the stars, they heat up and begin to glow at infrared wavelengths.
