NASA’s Hubble Space Telescope takes image of Horsehead Nebula in the Orion Molecular Cloud

Greenbelt, MD – Astronomers have used NASA’s Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory’s launch aboard the space shuttle Discovery on April 24th, 1990.

Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. The nebula is a favorite target for amateur and professional astronomers.

NASA Hubble Space Telescope sees Glow Worm like Galaxy

Greenbelt, MD – This charming and bright galaxy, known as IRAS 23436+5257, was captured by the NASA/ESA Hubble Space Telescope. It is located in the northern constellation of Cassiopeia, which is named after an arrogant, vain, and yet beautiful mythical queen.

The twisted, wormlike structure of this galaxy is most likely the result of a collision and subsequent merger of two galaxies.

NASA reports data from Planck Spacecraft reveals Universe Older than previously thought

March 22, 2013 |

Written by Dr. Tony Phillips
Science at NASA

Washington, D.C. – Europe’s Planck spacecraft has obtained the most accurate and detailed map ever made of the oldest light in the universe. The map results suggest the universe is expanding more slowly than scientists thought, and is 13.8 billion years old, 100 million years older than previous estimates.

The data also show there is less dark energy and more matter in the universe than previously known.

NASA’s Hubble Space Telescope proves that everything is not as it appears

NASA’s Goddard Space Flight Center

Greenbelt, MD – Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high resolution lets astronomers see individual stars, even in the crowded core.

The clusters all look very similar, and in Hubble’s images it can be quite hard to tell them apart – and they all look much like NGC 411, pictured below.

NASA’s Hubble Space Telescope sees Star forming regions in Large Magellanic Cloud

NASA’s Goddard Space Flight Center

Greenbelt, MD – Nearly 200,000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy.

Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colors, visible in this image from the NASA/ESA Hubble Space Telescope.

NASA’s Spitzer and Hubble space telescopes reveal Brown Dwarf’s Stormy Weather

January 15, 2013 |

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

Pasadena, CA – Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of a brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange worlds.

Brown dwarfs form out of condensing gas, as stars do, but lack the mass to fuse hydrogen atoms and produce energy. Instead, these objects, which some call failed stars, are more similar to gas planets with their complex, varied atmospheres.

This artist’s illustration shows the atmosphere of a brown dwarf called 2MASSJ22282889-431026, which was observed simultaneously by NASA’s Spitzer and Hubble space telescopes. The results were unexpected, revealing offset layers of material as indicated in the diagram. For example, the large, bright patch in the outer layer has shifted to the right in the inner layer. The observations indicate this brown dwarf — a ball of gas that “failed” to become a star — is marked by wind-driven, planet-size clouds. (Image credit: NASA/JPL-Caltech)

NASA Hubble Space Telescope takes image of two puzzling galaxies in the Constellation of Centaurus

January 7, 2013 |

NASA’s Goddard Space Flight Center

Greenbelt, MD – The Universe loves to fool our eyes, giving the impression that celestial objects are located at the same distance from Earth. A good example can be seen in this spectacular image produced by the NASA Hubble Space Telescope. The galaxies NGC 5011B and NGC 5011C are imaged against a starry background.

Located in the constellation of Centaurus, the nature of these galaxies has puzzled astronomers. NGC 5011B (on the right) is a spiral galaxy belonging to the Centaurus Cluster of galaxies lying 156 million light-years away from the Earth.

This image of galaxies NGC 5011B and NGC 5011C in the Constellation of Centaurus was taken with Hubble’s Advanced Camera for Surveys using visual and infrared filters. (ESA/Hubble & NASA)

NASA’s Hubble Space Telescope spies star forming ring of barred spiral galaxy

January 3, 2013 |

NASA’s Goddard Space Flight Center

Greenbelt, MD – The NASA’s Hubble Space Telescope provides us this week with a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097.

In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame.

NASA’s Hubble Space Telescope and NASA’s James Webb Space Telescope free e-Books available

January 2, 2013 |

NASA’s Goddard Space Flight Center

Greenbelt, MD – NASA’s Hubble Space Telescope has been providing amazing images of the universe since April 1990 and has led to remarkable discoveries. NASA’s James Webb Space Telescope is the next-generation telescope that will peer even deeper into space and unveil even more mysteries.

Both of these extraordinary telescopes are now the topics of two free e-Books available from the Apple iBookstore.

NASA’s Hubble Space Telescope captures image of super thin galaxy

December 26, 2012 |

NASA’s Goddard Space Flight Center

Greenbelt, MD -Like finding a silver needle in the haystack of space, the NASA Hubble Space Telescope has produced this beautiful image of the spiral galaxy IC 2233, one of the flattest galaxies known.

Typical spiral galaxies like the Milky Way are usually made up of three principal visible components: the disk where the spiral arms and most of the gas and dust is concentrated; the halo, a rough and sparse sphere around the disk that contains little gas, dust or star formation; and the central bulge at the heart of the disk, which is formed by a large concentration of ancient stars surrounding the Galactic Center.
