Astronomers Use Hubble to study bursts of Star Formation in the Dwarf Galaxies of the early Universe

They may only be little, but they pack a star-forming punch: new observations from the NASA/ESA Hubble Space Telescope show that starbursts in dwarf galaxies played a bigger role than expected in the early history of the Universe.

A Runaway Pinwheel Galaxy

Against a stunning backdrop of thousands of galaxies, this odd-looking galaxy with the long streamer of stars appears to be racing through space, like a runaway pinwheel firework.

Bizarre Alignment of Planetary Nebulae

Astronomers have used ESO’s New Technology Telescope and the NASA/ESA Hubble Space Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned — a surprising result given their different histories and varied properties.

First Time Hubble Spots True Color In A Azure Blue Planet

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true colour of a planet orbiting another star. If seen up close this planet, known as HD 189733b, would be a deep azure blue, reminiscent of Earth’s colour as seen from space. But do similarities to Earth end there? Read more:

Hubble Space Telescope has made its Millionth Observation

The NASA/ESA Hubble Space Telescope has made its millionth observation
since its launch 21 years ago. The telescope was used to search for the
chemical signature of water in the atmosphere of planet HAT-P-7b, a gas
giant larger than Jupiter which orbits the star HAT-P-7.

Greg talks about NASA LRO/LCROSS mission and the final upgrade of Hubble by the STS-125 crew.

Dr. Geller answers a viewer question about spectroscopy.

This episode of A Green Space – A Green Earth (GSGE in the menu tab) Bente reports on earthquakes, disaster mitigation and early warnings. Through a few examples we explain how space based technologies contributes to safe-guarding lives and property.

How are galaxies formed?  That’s a hot topic in astronomy these days.  In
this episode of The Astronomer’s Universe, called “Mergers and Acquisitions”,
Carolyn Collins Petersen explores the cosmic collisions that helped shape the
galaxies we see today. It’s a process that is still happening in our own Milky
Way Galaxy.  Come along and explore some beautiful scenes of galaxy mergers
from Hubble Space Telescope, The
European Southern Observatory
, Spitzer Space
Telescope
, and take a special ride through the future merger of the Milky Way and the Andromeda Galaxy, courtesy of Dr. John Dubinski at the University of Toronto (TAU in the menu tab)

“This month in Our Night Sky, Tavi Greiner, discusses the
complexities of Virgo’s brightest star, Spica.  She also reveals how you
can see some of the many satellites orbiting our planet.  After the show,

Atlantis Crew Doing Full Inspection of Hubble

NASA-RSS

Using cameras on the shuttle’s robotic arm, the crew is doing a full inspection of the telescope’s exterior to examine its condition since it was last serviced in March 2002. The Mission Status Briefing with Tony Ceccacci, STS-125 Lead Flight Director, and John Morse, NASA’s Astrophysics Division Director, is scheduled for 4 p.m. EDT. If the Mission Management Team meeting concludes before the briefing, MMT Chairman LeRoy Cain may participate.

Look Up to See Hubble!

Today, at 14:01 EDT, Space Shuttle Atlantis launched from Kennedy Space Center for a fourth and final servicing mission to the Hubble Space Telescope.  Scheduled to arrive to the orbiting telescope on Wednesday, the seven-member crew will conduct five EVAs to repair science instruments, install new cameras, and replace batteries, thermal blankets, and gyroscopes.  The 11-day, $1-billion mission can be followed through Mission Specialist, Mike Massimino’s Twitter account, NASA’s Mission to Hubble page, and live on NASA-TV.

You can also follow Shuttle Atlantis and the Hubble Space Telescope from your backyard, simply by looking up.  You can find fly-over times for your region at Heavens Above and NASA’s Satellite Tracking.  Ranging between first and fourth magnitudes, Hubble is not as bright as other orbiting crafts, like Iridium satellites or the ISS, so you will need binoculars.  Bright or not, its an exciting experience to watch the Hubble pass overhead, especially when you know that there are astronauts there, servicing the telescope as it orbits our planet!

NASA’s Great Observatories Celebrate the International Year of Astronomy With a National Unveiling of Spectacular Images

In 1609, Galileo first turned his telescope to the heavens and gave birth to modern astronomy. To commemorate four hundred years of exploring the universe, 2009 is designated the International Year of Astronomy.

NASA’s Great Observatories – the Hubble Space Telescope, Spitzer Space Telescope, and Chandra X-ray Observatory – are marking the occasion with the release of a suite of images at over 100 planetariums, museums, nature centers, and schools across the country in conjunction with Galileo’s birthday on February 15.

The selected sites will unveil a large 9-square-foot print of the spiral galaxy Messier 101 that combines the optical view of Hubble, the infrared view of Spitzer, and the X-ray view of Chandra into one multi-wavelength picture. “It’s like using your eyes, night vision goggles, and X-ray vision all at the same time,” says Dr. Hashima Hasan, lead scientist for the International Year of Astronomy at NASA Headquarters in Washington.

Participating institutions also will display a matched trio of Hubble, Spitzer, and Chandra images of Messier 101. Each image shows a different wavelength view of the galaxy that illustrates not only the different science uncovered by each observatory, but also just how far astronomy has come since Galileo.

NASA Invites Public to Choose Hubble’s Next Discovery

NASA Invites Public to Choose Hubble’s Next Discovery
 
 

WASHINGTON — NASA is giving everyone the opportunity to use the world’s most celebrated telescope to explore the heavens and boldly look where the Hubble Space Telescope has never looked before.

NASA is inviting the public to vote for one of six candidate astronomical objects for Hubble to observe in honor of the International Year of Astronomy. The options, which Hubble has not previously photographed, range from far-flung galaxies to dying stars. Votes can be cast until March 1. Hubble’s camera will make a high resolution image revealing new details about the object that receives the most votes. The image will be released during the International Year of Astronomy’s “100 Hours of Astronomy” from April 2 to 5.

Space enthusiasts can cast their vote at:

http://YouDecide.Hubblesite.org

Everyone who votes also will be entered into a random drawing to receive one of 100 copies of the Hubble photograph made of the winning celestial body.
