NASA: Chandra X-ray Observatory Discovers Nearest Pair of Supermassive Black Holes

Astronomers using NASA's Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Approximately 160 million light years from Earth, the pair is the nearest known such phenomenon.

The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago...

Status of LCA Tejas and Kaveri Engine

Tejas (LCA) , India's very own Light Combat Aircraft has achieved an important milestone by gaining Initial Operational Clearance (IOC)  in December 2010 . This has authenticated the Indian aircraft's airworthiness. The birth of India's first fighter aircraft is thus certified. So far, 1,659 flight tests have been completed.

LCA, Tejas Phase-ll Programme (Air Force version) was sanctioned in November 2001 at a cost`of Rs.3301.78 Cr. with Probable Date of Completion (PDC) of December 2008. The project is likely to be completed by December 2012 with an additional cost of Rs.2475.78 Cr. The additional cost is to meet the expanded scope of the programme, increased cost of materials, manpower, maintenance of facilities, etc. 

Indian Air Force has ordered 40 Tejas Mk-I aircraft (20 aircraft in IOC and 20 aircraft in FOC standard). Two aircraft will be ready by March 2012 for induction.
