Indian space telescope measures star parameters in Taurus
India's first multi-wavelength space telescope AstroSat has performed the most sensitive measurement of X-ray polarisation of a pulsar, fast-spinning neutron star, in the Taurus constellation. The pulsar powers the Crab Nebula that formed after a supernova explosion, which was recorded by Chinese astronomers in the year 1054. AstroSat was launched in September 2015 by ISRO aboard its PSLV rocket.
