The Lifestyles of Famous, Fast-Living Stars
The Carina Nebula contains the famous blue star Eta Carinae, which has the highest luminosity of any star we know. And in the same nebula live two other life-in-the-fastlane stars, and the Hubble Space Telescope has provided this gorgeous, gorgeous image of them. Until recently these colossal stars — two of our [...]

"Loner" Galaxy is Actually in the 'Hood
Astronomers have long wondered why a small, nearby, isolated galaxy is pumping out new stars faster than any galaxy in our local neighborhood. Usually, galaxies need some sort of gravitational interaction with other galaxies to trigger star formation, and galaxy NGC 1569 appeared to be a loner, far away from other galaxies, but churning [...]

W00T! Hubble is Back to Work!
Yes! (*Fist pump*) The Hubble Space Telescope is back in business. After overcoming a few glitches in bringing the orbiting Hubble back online, engineers and scientists aimed the telescope's prime camera, the Wide Field Planetary Camera 2 (WFPC2), at a pair of gorgeous-looking interacting galaxies called Arp 147. Scientists say the image demonstrates the [...]

Looking Good –So Far — For Hubble
So far, everything is going well and as planned for the Hubble Space Telescope's long-distance 'brain surgery.' During the night of Oct. 15, Space Telescope Operations Control Center engineers at NASA’s Goddard Space Flight Center successfully turned on and checked out Side B of Hubble’s Science Instrument Control and Data Handling (SIC&DH) system. [...]

Procedure to Repair Hubble Begins Wednesday
The procedure to begin "brain surgery" on the Hubble Space Telescope will begin at 6:00 am EDT (10:00 GMT) on October 15. The venerable space telescope will be put into electronic hibernation; then engineering teams will work from the ground around the clock for two days to reconfigure a data handler system which failed [...]

Hubble's Heritage
Here's another anniversary for you and more fodder to either ease or add to your Hubble "angst": Ten years ago, the Hubble Heritage Project began. What is Hubble Heritage? After the Hubble Space Telescope was fixed of its spherical aberration problem in December of 1993, HST started churning out incredible images. [...]

Hubble Malfunction Pushes Atlantis Service Mission into 2009
The fifth and final service mission to the Hubble Space Telescope is to be postponed until January as a mystery malfunction on Saturday crippled the observatory's ability to transmit data to Earth. The STS-125 mission was set to launch in two weeks so essential upgrades to Hubble could be carried out, but Space Shuttle Atlantis [...]

Help Your Hubble ANGST With Latest Survey Images
Everyone is suffering from severe angst about the fate of the Hubble Space Telescope, and now, on the heels of Hubble's data controller failure news comes more ANGST. But this is a good ANGST – which is an acronym that stands for ACS Nearby Galaxy Survey Treasury. The Advanced Camera for Surveys (ACS) [...]

Shuttle Mission to Hubble Delayed
Because of delays and complications from Hurricane Ike, the launch date for space shuttle Atlantis' STS-125 mission to service the Hubble Space Telescope has been delayed four days until Oct. 14 at 10:19 p.m. EDT. The delay is not a surprise. The crew and mission controllers missed out on a week of valuable training [...]

Hubble NICMOS Instrument Experiences Anomaly
A cooling system for the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) science instrument aboard the Hubble telescope experienced an anomaly during a restart, causing the instrument to go into safe mode. After a couple of additional restarts, the problem still persists, and a decision was made for NICMOS to "stand down" while [...]

Do All Galaxies Have Tentacles?
This Hubble Space Telescope image of two spiral galaxies shows an interesting feature on the smaller galaxy. Silhouetted in front of the larger background galaxy is a small galaxy, and tentacles of dust can be seen extending beyond the small galaxy's disk of starlight. Skeletal tentacles of dust can be seen extending beyond [...]

Clash of Clusters Separates Dark Matter From Ordinary Matter
A powerful collision of galaxy clusters captured by NASA's Hubble Space Telescope and Chandra X-ray Observatory provides evidence for dark matter and insight into its properties. Observations of the cluster known as MACS J0025.4-1222 indicate that a titanic collision has separated dark matter from ordinary matter. The images also provide an independent confirmation of [...]

Hubble Spies Beautiful, Beastly Monster Galaxy
Complete with tentacles, a supermassive black hole and x-ray emitting gas, a monster of a galaxy has been found by NASA's Hubble Space Telescope, and is helping astronomers answer a long-standing puzzle. The very active galaxy NGC 1275 has giant but beautiful and delicate filaments influenced and shaped by a beastly-strong extragalactic magnetic [...]
