Astronomers, with the help of Astrosat, have spotted a massive intriguing globular cluster in the Milky Way galaxy with rare hot UV-bright stars in it.
AstroSat is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously. Hence, statement 1 is correct.
It enables the simultaneous multi-wavelength observations of various astronomical objects with a single satellite.
It was launched on September 28, 2015, by PSLV-C30 from Satish Dhawan Space Centre, Sriharikota.
The minimum useful life of the AstroSat mission is expected to be 5 years.
The scientific objectives of the AstroSat mission are-
To understand high energy processes in binary star systems containing neutron stars and black holes.
Estimate magnetic fields of neutron stars.
Study star birth regions and high energy processes in star systems lying beyond our galaxy.
Detect new briefly bright X-ray sources in the sky.
Perform a limited deep field survey of the Universe in the Ultraviolet region.
