India is set to introduce polymer currency notes from FY28, with ₹10 and ₹20 denominations leading the rollout.

Designed to last two to four times longer than paper notes, they will reduce wear and tear, improve durability, and help expand currency production capacity. A wider rollout will follow if RBI’s field trials prove successful.

India’s first ‘private, branded’ train, launched by the Indian Railway Catering and Tourism Corporation (IRCTC) between Lucknow and Delhi, will run as the ‘Sprite’ Tejas Express.

STELLAR EVOLUTION
-Life Cycle: Nebula —> Protostar —> Main-sequence Star —> Red Giant/Red Supergiant —> Stellar Remnant.
-Sun-like stars: Red Giant —> Planetary Nebula —> White Dwarf —> eventually Black Dwarf.
-Massive stars: Red Supergiant —> Supernova —> Neutron Star/Pulsar or Black Hole.
-White Dwarf: Hot, Earth-sized, extremely dense dead stellar core; no sustained nuclear fusion; supported by electron degeneracy pressure.
-Pulsar: Rapidly rotating, highly magnetised neutron star emitting periodic radiation pulses.

🔭 IN NEWS: eRASSU J0608
Two white dwarfs orbit each other every 374 seconds (~6 min) and are rapidly spiralling inward, largely due to gravitational-wave energy loss.

Missions mentioned:
eROSITA —> X-ray telescope on Russian-German Spektr-RG | Einstein Probe —> Chinese-led X-ray mission | NICER —> NASA X-ray instrument on ISS | XMM-Newton —> ESA X-ray space observatory.
