This colorful collection of Hubble Space Telescope images of portion of 
the Monkey Head Nebula reveals a collection of carved knots of gas and 
dust silhouetted against glowing gas. The cloud is sculpted by 
ultraviolet light eating into the cool hydrogen gas.

In celebration of the 24th anniversary of the launch of NASA's Hubble 
Space Telescope, astronomers have captured infrared-light images of a 
churning region of star birth 6,400 light-years away.

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 and Sharpless Sh2-252).

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.

The Hubble Space Telescope is a project of international cooperation 
between NASA and the European Space Agency. NASA's Goddard Space Flight 
Center in Greenbelt, Md., manages the telescope. The Space Telescope 
Science Institute (STScI) in Baltimore conducts Hubble science 
operations. STScI is operated for NASA by the Association of 
Universities for Research in Astronomy, Inc., in Washington.
