Hubble Confirms Comet-like Tail on Vaporizing Planet
Next time you hear someone complaining that it's too hot outside, you can make them feel better by pointing out that at least their planet isn’t so hot it is vaporizing into space. Unless of course you happen to be speaking to someone from the gaseous extrasolar planet HD 209458b. New observations from the Hubble [...]

Hubble, Bubble, Toil and Star Formation
OK, that headline doesn't rhyme, but this incredible new Hubble image looks like a witch's cauldron of an exotic cosmic brew. It billows with huge clouds of gas and dust and is sprinkled with Eye of Newt, um…er, bright blue hot young stars. These dust clouds in NGC 2467 look like a murky, shadowy liquid, [...]

Dying Star or Beautiful Bird?
What a gorgeous new Hubble image! At first glance this object looks like a beautiful, giant, translucent bird. But it is actually star shedding its outer atmosphere. The cloud around this bright star is called IRAS 19475+3119. It lies in the constellation of Cygnus (the Swan) about 15, 000 light-years from Earth in the plane [...]

Hubble Captures Beautiful Baby Stars
Within the Large Magellenic Cloud is one of the most active star forming regions in our nearby Universe. This new Hubble image highlights N11 – also known as the Bean Nebula — a beautiful region of energetic star formation. The billowing pink clouds that look like cotton candy and bright bubbles of glowing gasses and [...]

Hubble Delves into Two Recent Jupiter Mysteries
Jupiter has a few mysteries these days. Between an equatorial belt that has gone missing and an impact that didn't leave a mark, astronomers decided they needed to put the Hubble Space Telescope on the case. New and detailed observations from the venerable space telescope have provided some insights into these two recent [...]

Life-size Wooden Spacecraft Sculptures
If you think about it, spacecraft are kind of ethereal in that once they are launched into space, we don't ever see them again. Australian artist Peter Hennessey has created life-size wooden sculptures of several different spacecraft, giving people the chance to see and touch these objects that are immediately recognizable but which we [...]

New Hubble Images Zoom In on Asteroid Impact on Jupiter
When amateur astronomer Anthony Wesley from Australia saw a dark spot the size of the Pacific Ocean appear on Jupiter through his telescope on July 19, 2009, this started a flurry of astronomic activity, with other telescopes quickly slewing to take a look. It didn't take long for other astronomers to confirm Jupiter [...]

Hubble Captures Surprisingly Restless Stars on the Move
Using the Hubble Space Telescope, astronomers from the Max Planck Institute for Astronomy made two observations ten years apart of the giant nebula NGC 3603 and found a surprising amount of movement and unrest in one of the most massive young star clusters in the Milky Way. The comparison images reveal several hundred stars [...]

Wild and Crazy Multi-Planetary System Surprises Astronomers
Astronomers are finding that not only are there a wide range of different extrasolar planets, but there are different types of planetary systems, as well. "We're not in Kansas anymore as far as solar systems go," said Barbara McDonald from the University of Texas' McDonald Observatory, at the American Astronomical Society meeting in Miami, [...]

Hubble Confirms Star is Devouring Hot Exoplanet
We all like a hot meal, but this is really bizarre. Back in February, Jean wrote an article about WASP-12b, the hottest known planet in the Milky Way that is being ripped to shreds by its parent star. Shu-lin Li of the Department of Astronomy at the Peking University, Beijing, predicted that the [...]

Runaway Star Needs Its Own Reality Docu-Drama
In an astronomical version of "Biggest Loser" meets "Survivor," a heavy weight star has been kicked out of its stellar nursery. This huge runaway star is rushing away from its birthplace at more than 402,336 kilometers per hour (250,000 miles an hour), and it likely was ejected by a group of even larger sibling [...]

GOODS, Under Astronomers' AEGIS, Produce GEMS
No, not really (but I got all three key words into the title in a way that sorta makes sense). Astronomers, like most scientists, just love acronyms; unfortunately, like most acronyms, on their own the ones astronomers use make no sense to non-astronomers. And sometimes not even when written in full: GOODS = Great Observatories Origins Survey; OK [...]

Hubble's Birthday Gift to Us: Mystic Mountian
Happy 20th Birthday to the Hubble Space Telescope! While we should be showering HST with gifts, instead the telescope provides this present to us: an amazing view of what has been nicknamed "Mystic Mountain. " It is just a small portion of one of the largest known star-birth regions in the galaxy, [...]
