Hubble Space Telescope Has Been Hit By A Mechanical Failure

Hubble has been been operational for 28 years

BBC: Hubble telescope hit by mechanical failure

The Hubble Space Telescope is operating with only essential functions after it lost one of the gyroscopes needed to point the spacecraft.

The observatory, described as one of the most important scientific instruments ever created, was placed in "safe mode" over the weekend, while scientists try to fix the problem.

Hubble had been operating with four of its six gyroscopes when one of them failed on Friday.

The telescope was launched in 1990.

Is Our Galaxy Warped?

ESO 510-13: Warped Hubble Heritage Team (STScI/AURA), C. Conselice (U. Wisconsin/STScI) et al., NASA

Hubble Catches a Warped Spiral Galaxy in Profile -- Popular Science

The Hubble Heritage Team captured the warped structure of spiral galaxy ESO 510-13 so beautifully in this pretty space pic. Behold, the product of galactic collisions.

At least, that’s one theory. Most spiral galaxies are flat disks made up of millions of stars and gas and planets and whatnot orbiting a galactic center (which is thought to be, at least in the case of large galaxies, a supermassive black hole). These disks are thought to flatten out the way they do by the nature of the collision of gas clouds early in a galaxy’s lifespan.

Hubble Telescope Detects The Oldest Known Galaxy

The galaxy was already in existence 480 million years after the Big Bang.

From The BBC:

The Hubble Space Telescope has detected what scientists believe may be the oldest galaxy ever observed.

It is thought the galaxy is more than 13 billion years old and existed 480 million years after the Big Bang.

A Nasa team says this was a period when galaxy formation in the early Universe was going into "overdrive".

The image, which has been published in Nature journal, was detected using Hubble's recently installed wide field camera.

Hubble Harvests Distant Solar System Objects

This is an artist's concept of a craggy piece of Solar System debris that belongs to a class of bodies called trans-Neptunian objects (TNOs). Astronomers culling the data archives of NASA's Hubble Space Telescope have added 14 new TNOs to the catalog. The newfound TNOs range from 25 to 60 miles (40-100 km) across. Their method promises to turn up hundreds more. In this illustration, the distant Sun is reduced to a bright star at a distance of over 3 billion miles. (Credit: NASA, ESA, and G. Bacon (STScI))

From Science Daily:

ScienceDaily (Sep. 13, 2010) — Beyond the orbit of Neptune reside countless icy rocks known as trans-Neptunian objects (TNOs). One of the biggest, Pluto, is classified as a dwarf planet. The region also supplies us with comets such as famous Comet Halley. Most TNOs are small and receive little sunlight, making them faint and difficult to spot.

Hubble Spots Ghostly Space Spiral

From Discovery News:

When I first saw this ghostly Hubble Space Telescope image, I assumed that faint blurry spiral was a lens flare or some other photographic anomaly. But on closer inspection, the details started to present themselves.

As imaged by the space telescope's sensitive Advanced Camera for Surveys, this striking pattern is formed by material being ejected from a dying star. But this isn't a lone star; there's a second star -- a binary partner -- orbiting with it and modulating the expanding gas.

Wow! Celebrate Hubble’s 20th With Best Space Image Ever

From Wired Science:

We were already dreading the day Hubble dies, but this mind-blowing new image released to celebrate the space telescope’s 20th anniversary makes us wish for eternal life for the famous satellite even more.

This new gem rivals what may be Hubble’s most famous image, a shot of the Pillars of Creation taken in 1995. The shot above is of a star-forming region in the Carina Nebula. The enormous pillar of gas and dust is 3 light-years tall. The seam in the middle is the result of new stars forming and emitting powerful gas jets that are ripping the pillar apart.

Hubble Confirms Cosmic Acceleration With Weak Lensing

This image shows a smoothed reconstruction of the total (mostly dark) matter distribution in the COSMOS field, created from data taken by the NASA/ESA Hubble Space Telescope and ground-based telescopes. It was inferred from the weak gravitational lensing distortions that are imprinted onto the shapes of background galaxies. The color coding indicates the distance of the foreground mass concentrations as gathered from the weak lensing effect. Structures shown in white, cyan and green are typically closer to us than those indicated in orange and red. To improve the resolution of the map, data from galaxies both with and without redshift information were used. The new study presents the most comprehensive analysis of data from the COSMOS survey. The researchers have, for the first time ever, used Hubble and the natural "weak lenses" in space to characterise the accelerated expansion of the universe. Credit: NASA, ESA, P. Simon (University of Bonn) and T. Schrabback (Leiden Observatory)

From Reuters:

A group of astronomers [1], led by Tim Schrabback of the Leiden Observatory, conducted an intensive study of over 446 000 galaxies within the COSMOS field, the result of the largest survey ever conducted with Hubble. In making the COSMOS survey, Hubble photographed 575 slightly overlapping views of the same part of the Universe using the Advanced Camera for Surveys (ACS) onboard Hubble. It took nearly 1000 hours of observations.

Hubble Telescope Captures Saturn's Eerie Twin Aurorae

Astronomers had a rare chance to view Saturn with its rings edge on. It meant they could study the planet's Northern and Southern lights

From The Daily Mail:

A spectacular light show on Saturn has been captured in unique new photos of the ringed planet.

The aurora images captured by the Hubble Space Telescope (HST) were made possible by a rare chance to see the planet with its rings edge-on and both poles in view.

It takes Saturn almost 30 years to orbit the Sun, and during that time such a picture opportunity occurs only twice.

Hubble Telescope Captures Earliest Images Of Universe - When It Was Just A 'Baby' At 600 Million Years

Deep space time: the Hubble picture shows the earliest ever seen galaxies which are circled in the boxes in the inset images on the left

From The Daily Mail:

The Hubble telescope has captured the earliest image yet of the universe - just 600 million years after the Big Bang.

It is the most complete picture taken in near-infrared light of the early universe, showing the first infant star clusters.

To give some perspective, the light left these galaxies 8billion years before our own Sun and Earth had even formed.

Scientists released the 'baby pictures' at a meeting of the American Astronomical Society.

Hubble Sees Most Distant Galaxies

Very distant galaxies were spotted in the Hubble Ultra Deep Field

From BBC:

Nasa's Hubble Space Telescope (HST) has captured its deepest view of the Universe, producing images of galaxies that have never been seen before.

The pictures were acquired by the HST's new Wide Field Camera 3 (WFC3).

This highly sensitive camera can see starlight from far-off objects - light that has been "stretched" by the expanding Universe.

Hubble Captures Sparkling ‘Jewel Box’ Star Cluster

From Wired Science:

This stunning image of the Kappis Crucis Cluster, nicknamed the “Jewel Box,” was one of the last gifts from a retiring camera on the Hubble Space Telescope.

Just before NASA brought the Wide Field Planetary Camera 2 back to Earth in mid-2009, it snapped this photo of the core of the NGC 4755 star cluster, the first comprehensive image of an open galactic cluster taken in multiple wavelengths. Using seven different filters, Hubble captured the Jewel Box cluster in far ultraviolet to near-infrared light. The different colors of the stars — from pale blue to bright ruby red — result from their differing intensities at various ultraviolet wavelengths.

Pallas Is 'Peter Pan' Space Rock

From The BBC:

The Hubble telescope has provided new insight on 2 Pallas, one of the largest asteroids in the Solar System.

The nearly 600km-wide rock is an example of an object that started out on the process of becoming a planet but never grew up into the real thing.

Researchers have published a 3D model of the grapefruit-shaped mini-world in Science magazine.

Hubble's data makes it possible to discern surface features, including what appears to be a big impact crater.

After Repairs, New Space Images From Hubble

The Hubble's new Wide Field Camera 3 peered into one of the more crowded places in the universe in this view of a small region inside the globular cluster Omega Centauri, which has nearly 10 million stars. NASA, ESA, and the Hubble SM4 ERO Team

From New York Times:

The cosmic postcards are back.

Astronomers on Wednesday unveiled new pictures and observations from the Hubble Space Telescope. With the exception of a picture last month of the bruise on Jupiter caused by a comet, they were the first data obtained with the telescope since a crew spent 13 days in orbit last May replacing, refurbishing and rebuilding its vital components.

“This is truly Hubble’s new beginning,” Edward Weiler, the associate administrator for science at the National Aeronautics and Space Administration, said at a news conference in Washington.

Hubble's Deepest Look Into Space, Now Rendered In 3D

From Popular Science:

Over a period of four months in late 2003, the Hubble telescope assembled an image that represents the deepest look into space every composed. The Ultra Deep Field image captures an estimated 10,000 galaxies, some as old as 13 billion years (just a few hundred million years after the Big Bang, going by most estimates), all squeezed into a sliver of sky no bigger than what you'd see behind a 1-millimeter square postage stamp held one meter away.

Here's what it looks like in 3D.

Hubble's Troubles Surprised Shuttle Crew

This NASA image shows the Hubble Space Telescope following grapple of the giant observatory by the shuttle's Canadian-built remote manipulator system on May 13. US astronauts aboard the shuttle Atlantis bid the Hubble telescope a wistful farewell Tuesday, ending a grueling revamp to equip the aging stargazer to explore the cosmos for years to come. (AFP/NASA/File)

From Yahoo News/Reuters:

CAPE CANAVERAL, Florida (Reuters) – Years of training didn't prepare the shuttle Atlantis astronauts for the problems encountered during NASA's final servicing mission to the Hubble Space Telescope, the crew said on Wednesday.

With the refurbished telescope back in orbit, the seven shuttle astronauts took some time off and began preparing for Friday's homecoming at the Kennedy Space Center in Florida.

"It's amazing looking back at how hard things looked a couple of times -- more difficult than I ever expected -- and then to overcome and wind up with everything done in the way that it was. We were very successful," Atlantis commander Scott Altman told reporters during an in-flight news conference on Wednesday.

From Yahoo News/AP:

CAPE CANAVERAL, Fla. – Spacewalking astronauts completed repairs to the Hubble Space Telescope on Monday, leaving it more powerful than ever and able to peer even deeper into the cosmos — almost to the brink of creation. The last humans to lay hands on Hubble outfitted the observatory with another set of fresh batteries, a new sensor for precise pointing and protective covers.

That equipment, along with other improvements made over the last five days, should allow the telescope to provide dazzling views of the universe for another five to 10 years.

"This is a very important moment in human history," Hubble senior project scientist David Leckrone said in Houston. "We will rewrite the textbooks at least one more time."

The deployed Hubble telescope

From The CBC:

Happy birthday, Hubble

This galaxy was chosen as a subject for the Hubble Space Telescope because it won the most votes in a competition hosted by the Space Telescope Science Institute. The contest was held in celebration of 2009's designation as the International Year of Astronomy. This year also marks the Hubble telescope's 19th year in operation. This group of three galaxies is known as Arp 274, and is about 400 million light years away from Earth in the constellation Virgo. You can see the birthplace of new stars in the small knots of bright blue in the small galaxy on the left, and the arms of the galaxy on the right. (NASA)
