The fake colors of Hubble photographyJan 25 2010

Those wildly colorful Hubble telescope photos...how do they get them to look like that?

The colors in Hubble images, which are assigned for various reasons, aren't always what we'd see if we were able to visit the imaged objects in a spacecraft. We often use color as a tool, whether it is to enhance an object's detail or to visualize what ordinarily could never be seen by the human eye.

Hubble goes deepDec 09 2009

In 2004, the Hubble Space Telescope took an image called the Hubble Ultra Deep Field; basically astronomers pointed the Hubble toward an "empty" part of space and took a long-exposure shot in the visible spectrum. What they found were thousands of far away galaxies from early in the development of the universe. Now the Hubble has peered even deeper into the universe in near-infrared and captured this image:

Each one of those little specks is an entire galaxy, some only 600 million years old. Here's a zoomed-in section:

Live on NASA TV right now: the launch of the Space Shuttle Atlantis, tasked to repair the Hubble telescope. Looks like if the weather holds, lift-off is around 2:01pm. (via @noahkalina)

Iconic Hubble photosJun 30 2008

From Harvard Magazine, an appreciation of the work that the Hubble telescope has done since its 1990 launch into orbit.

The "Pillars of Creation" may be the most iconic Hubble photograph ever taken. "Located in the Eagle Nebula, the pillars are clouds of molecular hydrogen, light years in length, where new stars are being born," says Aguilar. "However, recent discoveries indicate these pillars were destroyed by a massive nearby super nova some 6,000 years ago. This is a ghost image of a past cosmic disaster that we won't see here on Earth for another thousand years or so-and a perfect example of the fact that everything we see in the universe is history."

The Hubble Space Telescope was launched intoApr 28 2008

The Hubble Space Telescope was launched into space 18 years ago and to celebrate, NASA has put up a photo gallery of merging galaxies, galaxies as in love with each other as NASA is with the Hubble. Aww.

The Hubble telescope recently captured an imageJan 10 2008

The Hubble telescope recently captured an image of a double Einstein Ring.

An Einstein Ring happens when two galaxies are perfectly aligned. The closer galaxy acts as a lens, magnifying and distorting the view of a more distant galaxy. But today astronomers announced that they've discovered a double Einstein Ring: three galaxies are perfectly aligned, creating a double ring around the lensing galaxy.

On an upcoming servicing mission scheduled forJan 08 2008

On an upcoming servicing mission scheduled for August 2008, NASA plans to upgrade the Hubble telescope to be 90 times as powerful as it currently is. 90 times!

Two powerful new instruments will be installed on the mission. The Wide Field Camera 3 (WFC3) will allow Hubble to see fainter and more distant galaxies than anything it has seen before, shedding light on the early universe. This could allow Hubble to see galaxies so far away that we see them as they were just 400 million years after the big bang.

Using adaptive optics, which corrects for atmosphericSep 17 2007

Using adaptive optics, which corrects for atmospheric distortion, some astronomers have modified a ground telescope to yield sharper images than the Hubble.

Hubble's optics provide greater detail over a wider angle, while the Lucky camera as used at Palomar gives ultra-high resolution only for a tiny slice of the sky at one time.
