NASA's Hubble Space Telescope has captured an amazing view of a distant starbirth factory, a nebula known as the "Monkey Head," to help celebrate the upcoming 24th anniversary of the iconic instrument's launch.
The new infrared mosaic from Hubble — which launched on April 24, 1990 — shows knotty curls of dust and gas in the Monkey Head Nebula, a star-forming region that lies about 6,400 light-years away from Earth and is also known as NGC 2174 and Sharpless Sh2-252. Scientists used the Hubble mosaic to create a spectacular video of the Monkey Head Nebula to explain the new cosmic views.

"Massive, newly formed stars near the center of the nebula (and toward the right in this image) are blasting away at dust within the nebula," Hubble officials wrote in a description of the image, which was captured in February and released on Monday (March 17).

"Ultraviolet light from these bright stars helps carve the dust into giant pillars. The nebula is mostly composed of hydrogen gas, which becomes ionized by the ultraviolet radiation," they added. "As the interstellar dust particles are warmed from the radiation from the stars in the center of the nebula, they heat up and begin to glow at infrared wavelengths."

Though the Hubble Space Telescope is famous today for its gorgeous cosmic images and contributions to astronomy in a number of fields, the mission had a bumpy start. Hubble launched to space with a primary mirror ground to the wrong prescription, and five space shuttle missions were required to repair and upgrade the huge instrument.
Hubble officials have said they hope to keep the telescope operating through at least 2020, ensuring some scientific overlap with its designated successor, NASA's infrared-optimized James Webb Space Telescope. The $8.8 billion JWST mission is currently scheduled to launch in 2018.
