This is a more stellar view of the Pond Nebula, using Hubble's infrared capabilities. The reason you can see more stars is because infrared is able to cut through the dust and gas clouds to reveal the abundance of both young stars in the nebula, as well as more distant stars in the background.
The Rosette Nebula is 5,000 light-years from Earth. The distinctive nebula that some claim looks more like a skull has a hole in the middle that creates the illusion of its pink form.

The blue represents the gas of the young orion. This image is a composite observation of the Robert C. Byrd Green Bank Telescope and the wide field of the NASA Infrared Telescope.

"But ammonia is a great tracker of dense star-shaped gas."

At the center of the crab nebula is the crushed nucleus, or "heart" of an exploded star. The heart rotates 30 times per second and produces a magnetic field that generates 1 trillion volts, NASA said.

Jupiter's ice moon Europe may be the best place in the solar system to look for extraterrestrial life, according to NASA. The moon is about the size of the Earth's Tuna, and there is evidence that it has an ocean beneath its ice crust, which may hold twice as much water as Earth. NASA's 2016 budget includes a request for $ 30 million to plan a mission to explore Europe. The above image was taken by the Galileo spacecraft on November 25, 1999. It is a 12-frame mosaic and is considered the best image still on the side of Europe, which faces Jupiter.
This nebula, or cloud of gas and dust, is called RCW 34 or Gum 19. The brightest areas you can see is where the gas is heated by young stars. Eventually the gas burst out like champagne after a bottle was turned off. Scientists call this champagne flow. This new image of the nebula was captured by the Very Large Telescope of the European Space Organization in Chile. RCW 34 is in the constellation Vela in the southern sky. The name means "sails of a ship" in the Latin language.
The Hubble Space Telescope captured images of the three great moons of Jupiter – Io, Callisto and Europe – immediately passing by.
