Chronicles the history of Project Gemini, the precursor to the Apollo program that successfully designed and tested all components and procedures necessary to land men on the moon. The program's highlights include the first American extravehicular activity, or EVA; new orbital maneuvers including rendezvous and docking; and the first space walk.

Tycho Supernova Remnant

Tycho Supernova Remnant
Tycho supernova remnant

This image comes from a very deep Chandra observation of the Tycho supernova remnant, produced by the explosion of a white dwarf star in our Galaxy. Low-energy X-rays (red) in the image show expanding debris from the supernova explosion and high energy X-rays (blue) show the blast wave, a shell of extremely energetic electrons . These high-energy X-rays show a pattern of X-ray "stripes" never previously seen in a supernova remnant. Some of the brightest stripes can also directly be seen in the full color image, on the right side of the remnant pointing from the outer rim to the interior. The stellar background is from the Digitized Sky Survey and only shows stars outside the remnant.

These stripes may provide the first direct evidence that supernova remnants can accelerate particles to energies a hundred times higher than achieved by the most powerful particle accelerator on Earth, the Large Hadron Collider. The results could explain how some of the extremely energetic particles bombarding the Earth, called cosmic rays, are produced, and they provide support for a theory about how magnetic fields can be dramatically amplified in such blast waves.

The X-ray stripes are thought to be regions where the turbulence is greater and the magnetic fields more tangled than surrounding areas. Electrons become trapped in these regions and emit X-rays as they spiral around the magnetic field lines. Regions with enhanced turbulence and magnetic fields were expected in supernova remnants, but the motion of the most energetic particles -- mostly protons -- was predicted to leave a messy network of holes and dense walls corresponding to weak and strong regions of magnetic fields, respectively. Therefore, the detection of stripes was a surprise.

The size of the holes was expected to correspond to the radius of the spiraling motion of the highest energy protons in the supernova remnant. These energies equal the highest energies of cosmic rays thought to be produced in our Galaxy. The spacing between the stripes corresponds to this size, providing evidence for the existence of these extremely energetic protons.

The Tycho supernova remnant is named for the famous Danish astronomer Tycho Brahe, who reported observing the supernova in 1572. It is located in the Milky Way, about 13,000 light years from Earth. Because of its proximity and intrinsic brightness, the supernova was so bright that it could be seen during the daytime with the naked eye.

SSC Private Students - Hall Ticket Download

SSC Exam Centre - Documents in excel format

The following documents are useful in conducting SSC Exams at respective Centres.

SSC exams from March 24th to April 9th

This year total of 12,99,468 candidates will appear for SSC public examinations scheduled from March 24 to April 9 from 9.30 am to 12 noon. In total, 10,59,345 are regular and 2,40,128 are private candidates. 4,772 centers for regular candidates and 1,069 centers for private candidates. 944 ‘C’ category centers have been constituted.
OMR bar coding is also being implemented for all papers for this year too. Candidates can who did not get their hall tickets can download it from the website and attend exams along with the attestation of the headmaster of the school concerned.
Cellphones/pagers are strictly prohibited in the exam halls. Both invigilators and examinees are restricted from carrying cellphones along with them into the examination halls. It’s also advised that students/examinees visit the exam center allocated to them a day in advance to avert last moment difficulty in locating the centers. Students with bus passes will be allowed to travel in RTC buses to their centers on showing hall tickets.
Candidates appearing for the 1st time for the SSC regular or without school study with first language Hindi/Urdu/Tamil should write new pattern question paper objective paper. Once failed candidates belonging to March 2009 and earlier examinations who opted first language Hindi/Urdu/Tamil should write old pattern question paper (without objective paper) and this is the last chance for them.
