Stellar Snow Globe Mystery Solved With Hubble’s Help

Star clusters offer thrilling sights for stargazers.

Hubble Telescope Unveils Most Colorful View of the Universe Yet

NASA’s Hubble space telescope has unveiled its latest, greatest, deepest view of galaxies.

Comet ISON Plays Coy With Astronomers

  The latest observations from professional and amateur astronomers around the world show that the much-hyped comet ISON is still very much alive, and new data suggests that it may very well survive its close swing by the Sun on November 28. The big question on skywatchers’ minds, however, is how good of a sky…

New Cosmic Mystery: Butterfly Nebulae Align

Astronomers have stumbled on a cosmic mystery surrounding some of the most beautiful objects in our galaxy.  New deep-sky images of the Milky Way’s central core reveal picturesque butterfly-shaped gas clouds left behind by dying stars called bipolar planetary nebulae. And all appear to be mysteriously aligned with one another. Planetary nebulae form during the…

Comet ISON: Pop or Fizzle?

Will the much talked about comet ISON, discovered by Russian amateur  astronomers last year, turn out to be what some are calling the ‘comet of the century’ ? Not likely, says one researcher who has just concluded a preliminary study using the latest observations of the icy interloper. (Related: “New Comet Discovered.”) Astronomer Ignacio Ferrin,…

Photo: Hubble Spies Galactic Penguin and Egg

The Hubble Space Telescope has spied a pair of giant galaxies that bear a striking resemblance to a penguin guarding its egg. This cosmic zoological find—known as Arp 142—is in reality the blue spiral galaxy, NGC 2936, twisted by the gravitational pull of the smaller elliptical galaxy NGC 2937 below it. Hubble has been able…

Planet Debris Pollute Dead Stars

  A pair of dead stars sitting in a star cluster about 150 light years from Earth appear to have their atmospheres polluted with debris from asteroids . Astronomers say this suggests that the basic ingredients for making Earth-like planets could be quite  common in stellar nurseries across the cosmos. “We have identified chemical evidence…

Photo: Hubble Gets First Glimpse of Possible ‘Comet of the Century’

  Hubble has taken its first close-up views of the much anticipated and potential ‘comet of the century’. On the night of April 10th, the space telescope snapped an image in visible light of Comet ISON while it was still at a whopping distance of 394 million miles from Earth (386 million miles from the…

Hubble Survey Finds Galaxies Far, Far Away

  The image above, a composite of visible and infrared light images captured by the Hubble Space Telescope, shows the newfound locations of five small and incredibly ancient galaxies which are in the process of merging into a galactic cluster. Located a staggering 13.1 billion light-years away, these galaxies were in existence a mere 600…

Top Ten Space Blog Posts of 2010

Forget naughty or nice–with December now in full force, news outlets across the country are busy compiling their lists of what were the most popular/spectacular/important stories of 2010. We here at NG are no exception, and we’ve even compiled everything into a handy-dandy “best of” hub page for easy perusing. Since you know you love…

New Dark Matter Map Solving Galactic Puzzle?

One of the brilliant things about astrophysics is being able to take pictures of invisible stuff. Infrared telescopes, for example, allow astronomers to see “dark” nebulas (picture), clouds of dust and gas that weakly reflect light from nearby stars, glowing mostly in thermal emissions. Similarly, high-energy x-rays and gamma rays let scientists “see” black holes,…

What X-Rays Have Done for Astronomy

A Google search for anything today should immediately alert you to the fact that the software giant is celebrating the 115th anniversary of the discovery of x-rays. The penetrating radiation—a very high-energy form of light—was first documented by German scientist Wilhelm Conrad Roentgen in 1895. His famed x-ray picture of his wife’s hand made the…

Pluto Gets 14 New Neighbors

Beyond Neptune‘s orbit, roughly five billion miles from the sun, the solar system can seem like a dark, desolate place. But like the murky depths of the ocean, the darkness hides millions of mysterious bodies—or at least, so we think. Known collectively as trans-Neptunian objects, or TNOs, the first of this population to be discovered…

Jupiter News Flash: Pictures of “Nothing” Reveal Size of Recent Impact

It’s been tough times for Jupiter: The gas giant planet lost a belt in May, and, thanks to the diligence of amateur astronomers, we know that it has been struck by space objects at least three times in the course of a year. Australian amateur astronomer Anthony Wesley recorded the first impact in July 2009.…

Saturn’s Rings: 400 Years of Engagement

Today scientists with the Cassini mission to Saturn released yet another glorious picture of the gassy planet’s icy rings—in this case, a shot of the shepherd moon Prometheus carving arcs in the thin, outer F ring. —Image courtesy NASA/JPL/Space Science Institute Cassini has been in orbit around Saturn since June 2004, and it’s sent back…
