- Three space-based observatories Astrosat, Chandra, Hubble Space Telescope and a ground-based observatory HARPS have simultaneously detected a massive coronal explosion on the nearest planet-hosting star 'Proxima Centauri'
- ‘Proxima Centauri’ group of stars which hosts an Earth-like habitable planet orbiting within (Proxima Centauri) its habitable zone
- The exercise to investigate the fate of this Earth-like planet orbiting the ‘Proxima Centauri’, around 4.25 light years away from the Sun, involved a team of scientists from India, the US, Chile, France and Germany.
- ‘Proxima Centauri’ is a well-known flaring star where a large amount of energy is released as a result of magnetic reconnection and such stars (like Proxima Centauri) are known to flare on timescales of a few minutes to hours.
- Astrosat is a multi-wavelength astronomy mission built by a consortium of institutes across India led by ISRO Satellite Centre (ISAC, Bengaluru); Tata Institute of Fundamental Research (TIFR) , Mumbai; Indian Institute of Astrophysics (IIA), Bengaluru; Vikram Sarabhai Space Centre (VSSC, Thiruvananthapuram); Inter-University Centre for Astronomy and Astrophysics (IUCAA, Pune); and Space Applications Centre (SAC, Ahmedabad) in collaboration with University of Leicester (UK) and the Canadian Space Agency.
- The Chandra programme is managed by NASA’s Marshall Space Flight Center, Alabama (USA).
