The longest and darkest total lunar eclipse of the century will occur on Wednesday, giving sky enthusiasts all over the country an opportunity to witness the event. The total phase of this lunar eclipse will last 100 minutes. The last eclipse to exceed this duration was in July 2000. The next such eclipse will only take place in 2141. .. 

Space shuttle Endeavour completed its final flight by delivering the Alpha Magnetic Spectrometer to the International Space Station during the STS-134 mission.

"I think we all should be really impressed how big and magnificent that space station is," said STS-134 Mission Specialist Mike Fincke at the crew press conference following landing. Describing their parting view of the space station where he served once as crew and once as commander, he said, "We were impressed; we were excited like five-year olds at a rollercoaster park."

NASA has ended operational planning activities for the Mars rover Spirit and transitioned the Mars Exploration Rover Project to a single-rover operation focused on Spirit's still-active twin, Opportunity.

This marks the completion of one of the most successful missions of interplanetary exploration ever launched.

NASA's Space Shuttle mission STS-134 is the final flight for Endeavour and the second to last flight for the Space Shuttle Program. Endeavour cleared the pad just after 1826 Indian time 16th May (1256 GMT; 1356 BST). Its thunderous rise into a bright morning sky over the Kennedy Space Center in Florida was watched by hundreds of thousands of spectators.It is now on a path to rendezvous with the International Space Station (ISS) on Wednesday.The ship will deliver a $2bn particle physics experiment, known as the Alpha Magnetic Spectrometer (AMS), and a tray of critical spare parts..  

This month is the centenary of what is arguably the most amazing discovery of the 20th century – that the apparently solid world around us is mainly empty space.  Yes atoms the basic structural units of the entire universe are more than 99.9999% empty. (But empty space have quiet different meanings - quantum mechanics never speak of empty space). Imagine how it will be when there is no empty space in an atom - the unverse would shrink to 0.00000001 % (u can put 12 zeros between '.' and '1' ).

In May 1911 Philosophical Magazine published a research paper by Ernest Rutherford. He had analysed the results of some measurements by Hans Geiger and Ernest Marsden, who worked with him at Manchester University. The analysis led Rutherford to the conclusion that all the positive electric charge within an atom, and most of the mass, must reside in a tiny central region, with the negatively charged electrons swirling round far away. The central core became known as the atomic nucleus and the study of it led to our understanding of the fundamental particles and forces in the Universe.
