A quick check of Hubble’s gallery shows just 1,300 images; however more than raw 700,000 images reside in a vast archive with hundreds of potentially jaw-dropping astronomical scenes just waiting to be uncovered. That was the idea behind the European Space Agency’s international contest called Hubble’s Hidden Treasures. And now with the hard work of amateur astronomers and more than 3,000 submissions, some of Hubble’s incredible celestial treasures are revealed.
“The response was impressive, with almost 3000 submissions,” the ESA said in a press release. “More than a thousand of these images were fully processed: a difficult and time-consuming task. We’ve already started featuring the best of these in our Hubble Picture of the Week series.”

Judges ranked images from two categories, an image processing category and basic image searching category. Judges sifted through 1189 entries in the image processing category; a painstaking process of finding promising data and creating an attractive image using professional imaging software. But even if contestants didn’t have the technical know-how to create large mosaics and combine color filters, they could find stunning images in the Hubble archive using using simple online tools. The ESA received more than 1600 entries in this category.

“Every week, we search the archive for hidden treasures, process the scientific data into attractive images and publish them as the Hubble Picture of the Week,” says the ESA on their Hidden Treasures website. “But the archive is so vast that nobody really knows the full extent of what Hubble has observed.”
Josh Lake of the United States won with this awesome image of NGC 1763, part of the N11 star-forming region of the Large Magellanic Cloud.
First place in the processed category, which asked contestants to find promising data within the archive and process that scene into an attractive image, went to Josh Lake, from the United States. The image, which won the public vote, narrowly edged out other images. Lake produced a bold two-color image that is not in natural colors but contrasts light from glowing hydrogen and nitrogen. In natural colors, the two glowing gasses produce almost indistinguishable shades of red. Lake’s image separates them out into red and blue offering a dramatic view of the structure.
Messier 77 produced by Andre van der Hoeven, of the Netherlands came in a close second.
Andre van der Hoeven of the Netherlands came in a close second. The jury noted the impressive nature of Messier 77 in the image as well as the processing which combines several datasets from separate instruments to create the amazing image.
“This was my hardest job until now,” van der Hoeven says on the Flickr page. “Combining the different datasets to get equal colors was really hard. M77 was not fully covered by one dataset, so I had to combine channels of the WFPC2 with different wavelengths and tune the colors to get them to fit. But the result is in my opinion quite astonishing.”
We are as surprised as him that this image had not been released before.
Judy Schmidt of the United States entered this image of XZ Tauri, a new star lighting up a nearby cloud of gas and dust. She entered several images into the contest.
Third place went to an interesting image of XZ Tauri, a newborn star spraying gas into its surroundings as well as lighting up a nearby cloud of gas. The panel said it was a challenging dataset to process because Hubble captured only two colors in the region. “Nevertheless, the end result is an attractive image, and an unusual object that we would never have found without her help,” the panel said.
Revealing the challenge of many Hubble mosaics, the jury was impressed with the technical achievement Renaud Houdinet showed in putting together this ambitious view. He called this “The Great Mosaic Disaster in Chamaeleon. “Sometimes, things don’t turn out as they ought,” Houdinet admits on the Flickr description. Chamaeleon 1 is a large nebula near the south celestial pole and was not covered in one single Hubble image.
Robert Gendler took fifth place with an image of spiral galaxy Messier 96. You may know Gendler’s work as his version of Hubble’s image of NGC 3190 is the default image on the desktop of new Apple computers.

Hmm… not sure what I’d buy first if I had the extre lucre? A bigger telescope? Or a better computer? These images help me make that decision.. go for the better computer!
