Observations of Type Ia supernovae revealed an accelerating cosmic expansion, leading to the Nobel Prize-winning conclusion that an unknown force, dubbed dark energy, was at work. This enigmatic phenomenon accounts for […]
Early Perceptions and Changes in Attitudes Initially, fires in the mountains north of Los Angeles were viewed as natural spectacles rather than threats.

Historical Estimates of Universe Size The early 20th-century view of the universe was limited, with astronomers picturing it as infinitely old and unchanging, and the Milky Way as the entire universe. Harlow Shapley's work suggested our galaxy stretched 300,000 light years across. Edwin Hubble's observations in the 1920s revealed a […]
Historical Estimates of Universe Size In the early 20th century, the universe was thought to be infinite and unchanging, with Earth at its center. Astronomers like Harlow Shapley believed the Milky Way was essentially "the universe," stretching 300,000 light-years across. Edwin Hubble's 1929 measurements revealed a much larger universe, approximately […]
Asteroids, those celestial travelers, often capture our imagination and scientific curiosity. As we consider their paths and potential impacts on Earth, the intricate dance between these space rocks and our planet becomes a focal point of study. With Asteroid 2025 AB approaching, it offers an opportunity to reflect on how […]
Venus and Saturn Close Approach On January 17 and 18, 2025, Venus and Saturn will be in close conjunction, visible in the southwest sky after sunset.
