NASA begins deepest ever probe of the universe

Chennai, November 13, 2009 NASA EXPEDITION - JOHNSON SPACE CENTER:- To explore the Space beyond MARS and to bring in Scientific revolution in young minds, Maharishi Vidya Mandir Sr. Sec. School, Chetpet, Chennai and Maharishi International Residential School, Sriperumpudur, Kanchipuram District kept ;the best foot forward to spearhead the NASA Expedition. The vision became reality when 36 students along with 2 Teachers set a shining example by proving their mettle in broader perspective of Space Centre Research Practices between 18th October and 29th October, 2009. A 5-day long programme included Mars Landing Video Presentation, Rover Design & Parts Testing, Rover Construction, Rocket Design, Glider Project, Spectrometer, Mars Lander Design and Competition. The students were actively involved in the Project Demonstration divided into 5-teams. A formal event was hosted by the Educational Specialists in the Graduation Ceremony conducted on 23rd October, 2009 and the student delegates received their NASA Certificates of Merit with Gold Medal. NASA experts declared the school as the `BEST QUESTIONNAIRE OF THE WEEK’. At Cape Canaveral, Florida students viewed Apollo & Saturn-V Centre, Theatre, Spectrometer, Firing room theatre, Explored collection of Astronaut Artifacts with Armstrong landing on Moon 1969, Space Shuttle – simulation of an actual launch. At Orlando, Florida, SEA WORLD added fascination to the visiting crew with stunning SHAMU SHOW & WHALE & DOLPHIN THEATER. MANTA, JOURNEY TO ATLANTIS and KRAKEN remained thrill game rides. Coming to Universal Studios Orlando, Florida City Walk with a popular mix of imaginative Music, Comedy and Multi-media theatre provided a new experience of fun & frolic. A new ray of hope was provided by Hard rock and Islands of adventure. A raring & bold opportunity indeed to the students and teachers of Maharishi Vidya Mandir Institutions.

NASA’s Hubble, Spitzer and Chandra space telescopes are teaming up to look deeper into the universe than ever before and search for the most distant and faint galaxies that can possibly be seen.

With a boost from natural “zoom lenses” found in space, they should be able to uncover galaxies that are as much as 100 times fainter than what these three great observatories typically can see, NASA said.

In a collaborative programme called The Frontier Fields, astronomers will make observations over the next three years of six massive galaxy clusters, exploiting a natural phenomenon known as gravitational lensing.

The clusters are among the most massive assemblages of matter known, and their gravitational fields can be used to brighten and magnify more distant galaxies so they can be observed.

“The Frontier Fields programme is exactly what NASA’s great observatories were designed to do; working together to unravel the mysteries of the Universe,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington.

“Each observatory collects images using different wavelengths of light with the result that we get a much deeper understanding of the underlying physics of these celestial objects,” Grunsfeld said in a statement.

The first object they will view is Abell 2744, commonly known as Pandora’s Cluster. The galaxy cluster is the result of a simultaneous pile-up of four separate, smaller galaxy clusters that took place over a span of 350 million years.

Astronomers anticipate the observations will reveal populations of galaxies that existed when the universe was only a few hundred million years old.

“The idea is to use nature’s natural telescopes in combination with the great observatories to look much deeper than before and find the most distant and faint galaxies we can possibly see,” said Jennifer Lotz, a principal investigator with the Space Telescope Science Institute in Baltimore.

Data from the Hubble and Spitzer space telescopes will be combined to measure the galaxies’ distances and masses more accurately than either observatory could measure alone, demonstrating their synergy for such studies.

“We want to understand when and how the first stars and galaxies formed in the universe, and each great observatory gives us a different piece of the puzzle,” said Peter Capak, the Spitzer principal investigator for the Frontier Fields programme.

“Hubble tells you which galaxies to look at and how many stars are being born in those systems. Spitzer tells you how old the galaxy is and how many stars have formed,” Capak said.

The Chandra X-ray Observatory also will peer deep into the star fields. It will image the clusters at X-ray wavelengths to help determine their mass and measure their gravitational lensing power, and identify background galaxies hosting super massive black holes.
