1. What is AstroSat?
AstroSat is the first observatory class mission of India.
2. What is the speciality of AstroSat?
AstroSat has unique capability of taking simultaneous measurements in wide band from UV to hard X-rays through its four co-aligned experiments.
3. What is the life time of AstroSat?
AstroSat is designed for a life of five years.But it completed its designed life of five years in September, 2020 and continues to provide significant science results.
4. What are blackholes?
Blackholes are one of the three end states of a star. The other two are white dwarf and Neutron Star.
5. Blackhole do not emit light. How do we know they exit?
Blackhole though do not emit light, they affect the nearby light and matter due to their gravity, like bending of light or interaction with surrounding matter.
6. Is AstroSat good for blackhole studies?
AstroSat cannot study non interacting isolated blackholes. But in interacting binaries, AstroSat will start eating (accretion) matter. When the matter falls on a blackhole, on the way they emit X-rays which can be measured by AstroSat.
7. Only X-rays? What else AstroSat can Do?
AstroSat also carries a UV telescope which boosts of highest revolution UV imaging in existence today.
8. Great, Can I use AstroSat?
Yes, AstroSat operates as proposal based observatory. Any body who can conceive a good science problem can request observations with AstroSat.
9. No, I do not want to write proposal. Can I use old data?
Yes, the data obtained from AstroSat is stored (archived) at ISSDC (Indian Space Science Data Centre) at www.issdc.gov.in. You can visit that link for more details.
