Using data from NASA’s Fermi Gamma-ray Space Telescope, scientists have recently discovered a gigantic, mysterious structure in our galaxy. This feature looks like a pair of bubbles extending above and below our galaxy’s center. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old.

Denver Museum of Nature and Science: Hubble Space Telescope (HST) COSTAR package On Exhibit

Sunday, October 24th, 2010

I made it to the Denver Museum of Nature and Science to the Hubble Space Telescope (HST) COSTAR package Saturday. The COSTAR is located near the T-rex Café. The package is protected by a Plexiglas covering It is about the size of a grand piano. COSTAR stands for Corrective Optics Space Telescope Axial Replacement. This is the instrument that resolved the issue with flawed mirror problem that prevented Hubble from a clear focus. It needed eyeglasses and COSTAR was it. It was built by Ball Aerospace Corp. and installed in 1993. Since then other service missions have replace the old packages with their own corrective optics. COSTAR was removed from HST in 2009 during the fifth servicing mission and replaced by the Cosmic Origins Spectrograph.

Check out the photos in our gallery under telescopes at our website.

While I was there I also got to see the new upgraded IMAX. It is now digital and in 3-D. This was the first 3-D movie I seen in years. Wow how the technology has changed. I watched the HUBBLE 3-D movie wow between the sound system and the 3-D views it was amazing, I would recommend seeing it if you haven’t yet, it is definitely worth it.

DENVER – October 12, 2010 – Beginning this Friday, October 15, the Hubble’s Wide Field Planetary Camera 2, WFPC2, will be on display for a limited time at the Denver Museum of Nature & Science. The supercamera, which is the size of a baby grand piano, is credited with saving the Hubble Space Telescope mission and providing unprecedented and crystal clear pictures of our universe.

“The Wide Field Planetary Camera 2 ranks right up there with Galileo’s telescope and Newton’s apple, from a space science standpoint,” said Steven Lee, PhD, the Museum’s curator of planetary science. “From the public standpoint, this camera is Hubble. Hosting the WFPC2 is an amazing opportunity our museum, especially given the timing of our IMAX 3D grand opening featuring the Hubble film and our Space and Sea Spectacular scheduled for this weekend.”

Museum visitors will have a unique opportunity to see this remarkable scientific instrument, complete with several “craters” in its outer skin that were caused by micrometeorite impacts during its years in orbit. Special related programming will be offered on Saturday, October 16, and Sunday, October 17, during the Museum’s Space and Sea Spectacular, which is included with general admission. Additionally, visitors to the Museum’s new IMAX 3D theater will experience actual 3D footage taken in 2009 when shuttle astronauts removed WFPC2 from Hubble.

The Story of the WFPC2
The WFPC2 camera replaced the first camera on board NASA’s Hubble Space Telescope, which was launched in 1990 with the promise that it would bring in a new era of astronomical discovery. Soon after the launch, NASA learned that the first camera had a defective main mirror and transmitted only blurred images back to Earth. After three years of work by NASA scientists, the WFPC2 was installed and soon the camera began offering stunning, razor-sharp images of our universe.

For 16 years, the WFPC2 offered front-row seats to the impact of Comet Shoemaker-Levy 9 on Jupiter, provided dramatic evidence for super-massive black holes at the core of many galaxies, detected thousands of galaxies in a “blank” region of the sky, observed weather on many of our neighboring planets, and returned views of star-birth in the Eagle Nebula’s “Pillars of Creation.” Many of these images were not only incredibly valuable to scientists, but also incredibly beautiful to the general public. Hubble became “the people’s telescope,” and the WFPC2 was the workhorse instrument of the mission; it was the camera that saved Hubble.

The WFPC2 was replaced with a new camera and returned to Earth in 2009, during the final Shuttle mission to service the Hubble–and this effort became the storyline of Hubble, now playing in IMAX 3D at the Museum. Since May 2010, the camera has been on display at NASA’s Jet Propulsion Laboratory in California, where it was built. Through a special loan arrangement with NASA, it will make a brief stop in Denver while en route to NASA’s Goddard Space Flight Facility in Maryland.

Space & Sea Spectacular – IMAX 3D Opening Celebration
Free with Museum Admission on Saturday, October 16 and Sunday, October 17
The Museum is celebrating the grand opening of its new IMAX 3D theater with a weekend full of free special programs and activities centered around space and sea. Visitors will learn about 3D photography, view the Sun through solar telescopes, explore the world of robotics, and take a look at some of the amazing sea shells from the Museum’s collections. Special guests will conduct chemistry experiments, give tours of the universe, answer questions about the fin whale skeleton floating overhead, and more. Below are highlights.

• 12:30 p.m. on Sunday – Astronaut Emeritus Bruce McCandless II shares stories of his space exploration and connection to the Hubble. He worked on designing Hubble to be serviceable in orbit, and was an astronaut on the April 1990 space shuttle mission that carried the telescope into orbit. He will participate in Q&A with the audience and be surrounded by dramatic space images within the planetarium.
• 3 p.m. on Sunday – McCandless shows the WFPC2 and the explains features engineered into Hubble and its instruments that allow for the on-orbit “house calls” and have made Hubble one of the premier scientific endeavors of all time
• 11:30 a.m. and 2 p.m. on Saturday – Steve Lee, the Museum’s space science curator, will explain his use of the Hubble Space Telescope and WFPC2 to observe weather on Mars.
IMAX 3D Digital Upgrades
The Museum recently completed digital upgrades to the latest IMAX 3D technology, which now delivers the world’s most immersive movie experience. Enhancements in the theater include IMAX’s powerful digital projection system, IMAX’s latest digital sound system, and a new IMAX screen.

Hubble 3D
Hubble 3D offers a gripping story full of hope, crushing disappointment, dazzling ingenuity, bravery, and triumph. Hubble recounts the amazing journey of the Hubble Space Telescope, arguably the most important scientific instrument since Galileo’s original telescope and the greatest success in space since the moon landing. Narrated by Leonardo DiCaprio and presented with the latest 3D technology, Hubble will change the way you see the universe. Showing daily at 11:30 a.m., 2 p.m., and 4 p.m., with an additional showing at 6 p.m. on Fridays and Saturdays. View the trailer and see ticket prices.

NASA’s Kepler Mission Discovers Two Planets Transiting the Same Star

NASA’s Kepler Mission Discovers Two Planets Transiting the Same Star Worlds on the Edge
The star system is oriented edge-on, as seen by Kepler, such that both planets cross in front, or transit, their star, named Kepler-9. This is the first star system found to have multiple transiting planets.

MOFFETT FIELD, Calif. — NASA’s Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.

The transit signatures of two distinct planets were seen in the data for the sun-like star designated Kepler-9. The planets were named Kepler-9b and 9c. The discovery incorporates seven months of observations of more than 156,000 stars as part of an ongoing search for Earth-sized planets outside our solar system. The findings will be published in Thursday’s issue of the journal Science.

Kepler’s ultra-precise camera measures tiny decreases in the stars’ brightness that occur when a planet transits them. The size of the planet can be derived from these temporary dips.

The distance of the planet from the star can be calculated by measuring the time between successive dips as the planet orbits the star. Small variations in the regularity of these dips can be used to determine the masses of planets and detect other non-transiting planets in the system.

In June, mission scientists submitted findings for peer review that identified more than 700 planet candidates in the first 43 days of Kepler data. The data included five additional candidate systems that appear to exhibit more than one transiting planet. The Kepler team recently identified a sixth target exhibiting multiple transits and accumulated enough follow-up data to confirm this multi-planet system.

“Kepler’s high quality data and round-the-clock coverage of transiting objects enable a whole host of unique measurements to be made of the parent stars and their planetary systems,” said Doug Hudgins, the Kepler program scientist at NASA Headquarters in Washington.

Scientists refined the estimates of the masses of the planets using observations from the W.M. Keck Observatory in Hawaii. The observations show Kepler-9b is the larger of the two planets, and both have masses similar to but less than Saturn. Kepler-9b lies closest to the star with an orbit of about 19 days, while Kepler-9c has an orbit of about 38 days. By observing several transits by each planet over the seven months of data, the time between successive transits could be analyzed.

“This discovery is the first clear detection of significant changes in the intervals from one planetary transit to the next, what we call transit timing variations,” said Matthew Holman, a Kepler mission scientist from the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. “This is evidence of the gravitational interaction between the two planets as seen by the Kepler spacecraft.”

In addition to the two confirmed giant planets, Kepler scientists also have identified what appears to be a third, much smaller transit signature in the observations of Kepler-9. That signature is consistent with the transits of a super-Earth-sized planet about 1.5 times the radius of Earth in a scorching, near-sun 1.6 day-orbit. Additional observations are required to determine whether this signal is indeed a planet or an astronomical phenomenon that mimics the appearance of a transit.

NASA’s Ames Research Center in Moffett Field, Calif., manages Kepler’s ground system development, mission operations and science data analysis. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development.

Ball Aerospace and Technologies Corp. in Boulder, Colo., developed the Kepler flight system and supports mission operations with the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. The Space Telescope Science Institute in Baltimore archives, hosts and distributes the Kepler science data.

SOHO MDI Continuum Latest Image

Source – Space Weather News for August 8, 2010: http://spaceweather.com

On August 7th (1825 UT), magnetic fields around sunspot 1093 became unstable and erupted, producing a strong M1-class solar flare. Several amateur astronomers caught the active region in mid-flare, while NASA’s Solar Dynamics Observatory recorded an extreme ultraviolet movie of the entire event:
The eruption hurled a coronal mass ejection (CME) into space, just missing a direct sun-Earth line. Forecasters expect the cloud to deliver no more than a glancing blow to our planet’s magnetic field when it billows by on August 9th or 10th–not be a major space weather event.
Future eruptions could turn out differently. Active region 1093 is rotating toward Earth. By the end of this weekend, we’ll be in the line of fire if its magnetic fields become unstable again.

Heavy Metal Rock Set to Take the Stage – NASA Jet Propulsion Laboratory

Saturday, July 10th, 2010

PASADENA, Calif. – On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency’s Rosetta spacecraft, with NASA instruments aboard, will fly past asteroid Lutetia this Saturday, July 10.
The instruments aboard Rosetta will record the first close-up image of a metal asteroid. They will also make measurements to help scientists derive the mass of the object, understand the properties of the asteroid’s surface crust, record the solar wind in the vicinity and look for evidence of an atmosphere. The spacecraft will pass the asteroid at a minimum distance of 3,160 kilometers (1,950 miles) and at a velocity of 15 kilometers (9 miles) per second.
