There is a cavity at the centre of this galaxy as there has been no formation of new stars in the past 100 billion years.
Globular clusters are collections of thousands to millions of stars, moving as one unit.
Astrosat's UV capabilities allow hot stars to be seen individually, better estimate mass & temperature.
The find could help solve an elusive astrophysics problem for the 'missing mass in planetary nebulae'.
Tycho supernova, the remnant of which Astrosat captured, holds a special place in our history.
ISRO's space telescope AstroSat measures X-ray polarisation of the Crab pulsar in the Taurus constellation
The landmark measurement by the satellite's CZT (Cadmium-Zinc-Telluride) imaging instrument challenges theories of high energy X-ray emission from pulsars.
Indian astronomers obtain the ‘most precise hard X-ray polarization measurements of the Crab pulsar so far’
Crab pulsar contains 1.4 solar masses and rotates thirty times every second emitting a pulse of radiation in almost all wavelengths every 33 milliseconds.
More than 40 scientists from 13 Indian institutions played a role in the observation of gravitational waves from colliding neutron stars
The Indian scientists were part of the team of 1,200 scientists from 100 institutions worldwide.
The Indian assets that contibuted to the scientific understanding of the neutron star collision observed by LIGO
The HCT in Ladakh, the GMRT in Pune and the AstroSat, India's first dedicated space observatory launched by ISRO two years ago all played a role.
Scientists announce first direct observation of gravitational waves from the merger of two neutron stars
Near-simultaneous detection of the gravitational waves and gamma rays indicate that gravitational waves travel at the speed of light.
The Mars Orbiter Mission, The ScatSat-1 weather satellite and the AstroSat astronomical instrument all celebrated their birthdays.
The Science Technology and Innovation policy of 2013 envisages positioning India among the top five global scientific powers by 2020.
Hubble, Astrosat and Chnadra have simultaneously detected a massive coronal explosion on the nearest planet-hosting star 'Proxima Centauri'.
Astrosat, India's first dedicated space observatory, will be launched on Monday at 10 AM from the spaceport of Sriharikota in Andhra Pradesh. It is aimed at studying celestial objects.
India has signed up contracts to launch 23 foreign satellites soon
PSLV C30 carrying Astrostat and six passengers, one satellite each from Indonesia and Canada and four nanosatellites from the US, was launched at 10 a.m. on Monday.
STROSAT, satellite for the first dedicated Indian astronomy mission aimed at studying celestial objects, is scheduled for launch on 28 September, a senior Indian Space Research Organisation (ISRO) official said.
