Dark matter and dark energy: What the universe is made of, and what we still don’t know
Modern cosmology has precisely measured the universe's properties, yet dark matter and dark energy remain profound mysteries. While dark matter's gravitational effects are evident, its composition is unknown. Similarly, dark energy drives the accelerating expansion of the universe, but its nature eludes understanding, leaving scientists to seek breakthroughs through extensive cosmic observations.
She worked with Edwin Hubble at Harvard for 30 cents an hour and shaped the view of universe as we know it, yet never won a Nobel Prize
Henrietta Swan Leavitt, a Harvard Observatory 'human computer,' revolutionized astronomy in the early 20th century. Despite facing gender bias and low pay, she discovered 'Leavitt’s Law,' linking a Cepheid star's brightness to its pulsation period. This breakthrough enabled astronomers like Edwin Hubble to measure vast cosmic distances, proving the existence of galaxies beyond the Milky Way.
Origin story of our universe: James Webb Space Telescope's surprising discoveries prompt rethinking of cosmos
The James Webb Space Telescope has provided data that challenges the standard model of cosmology, particularly in relation to the formation of galaxies and the expansion of the universe.

Google Doodle honours Georges Lemaitre's Big Bang theory
New Delhi, July 17 (IANS) Google on Tuesday dedicated an animated Doodle to Belgian cosmologist Georges Lemaitre who in 1927 propounded the Big Bang theory when he theorised that the universe began as a single point and expanded to become as big as it is now.
