__________SN 2017hpa●It is a particular type of supernovae called I a supernova, which exploded in 2017.
●It helped narrow down the explosion mechanism of the supernovae by observations of unburned carbon in the early phase spectra.
●The explosive death of a star as a supernova is one of the most spectacular and catastrophic events in the Universe.
●Type Ia supernovae are the result of explosions of white dwarfs that exceed their mass beyond the Chandrasekhar limit through accretion of matter.
●Their homogeneous nature makes them extremely good standardizable candles to measure cosmological distances.
●However, the explosion mechanisms which create these supernovae (SNe), and the exact nature of their progenitor systems (star which is at the origin of a supernova phenomenon) are still not yet clearly understood.

__________Python-5 (Air to Air Missile)●Tejas, India's indigenous Light Combat Aircraft, added the 5th generation Python-5 Air-to-Air Missile (AAM) in its air-to-air weapons capability on April 27, 2021.
●Trials were also aimed to validate enhanced capability of already integrated Derby Beyond Visual Range (BVR) AAM on Tejas.
●The test firing at Goa completed a series of missile trials to validate its performance under extremely challenging scenarios.
●Derby missile achieved direct hit on a high-speed maneuvering aerial target and the Python missiles also achieved 100% hits, thereby validating their complete capability.
