Supreme Court Permits Two Days of Certified Green Crackers in Delhi-NCR

The Supreme Court of India permitted the bursting of certified green crackers in the Delhi-NCR region for two days, specifically on November 7 and November 8, within restricted time slots from 6 a.m. to 7 a.m. and 8 p.m. to 10 p.m. The court strictly prohibited bursting crackers within a 300-metre radius of hospitals, nursing homes, and notified silence zones, designating them as no-cracker zones. This ruling aims to balance traditional celebrations with the pressing need to curb air pollution and protect public health amidst severe environmental concerns.

  • The Supreme Court allowed certified green crackers in Delhi-NCR for two days on November 7 and 8.
  • Permitted time slots are restricted to 6 a.m. to 7 a.m. and 8 p.m. to 10 p.m.
  • A strict 300-metre no-cracker zone is enforced around hospitals, nursing homes, and silence zones.
Exam Points

New Research Reveals Milky Way Grew by Devouring Smaller Galaxies

Recent astronomical research reveals that the Milky Way galaxy grew to its current size through a violent past marked by continuous collisions and mergers with smaller galaxies. According to the study, this ancient accretion process left behind remnants known as 'ghost stars' scattered across the galaxy's halo. Unlike younger stars found within the spiral arms, these ancient stars provide crucial insights into the complex stellar composition and violent history of our galaxy. Astronomers state this research significantly enhances our understanding of galactic evolution and the dynamic nature of the universe.

  • The Milky Way expanded over time by devouring and merging with smaller galaxies.
  • 'Ghost stars' found in the galactic halo serve as remnants of these ancient cosmic mergers.
  • The study helps explain the presence of ancient stars in outer galactic regions compared to spiral arm stars.
Exam Points
  • Milky Way growth mechanism: Violent past mergers and galaxy devouring
  • Ghost stars location: Halo of the Milky Way galaxy
  • Significance: Explains massive size and stellar composition variations
