Discovery of Epimetheus by Richard Walker
Richard Walker, an astronomer, discovered Saturn's moon Epimetheus using advanced observational techniques. This moon, known for its unique orbital relationship with another moon, Janus, is a significant addition to the understanding of Saturn's diverse system. The discovery provided insight into moon formation and dynamics in the outer solar system. Walker's work contributed to the growing body of knowledge about celestial bodies beyond Earth.

Venera 3, a Soviet space probe, became the first human-made object to impact the surface of another planet when it crashed into Venus. Launched on November 16, 1965, it was designed to transmit data back to Earth about Venus's atmosphere and conditions. However, due to technical difficulties, the probe was only able to send back limited information before its abrupt landing. Regardless, this mission marked a milestone in planetary exploration.

Comet Ikeya–Seki, a noteworthy comet in the 20th century, made a remarkable close approach to the Sun, reaching perihelion at a distance of approximately 450,000 kilometers (279,617 miles). This event sparked considerable interest within the astronomical community, as such proximity allows for detailed observation and study of the comet's characteristics, including its tail and gaseous components. Observers around the world anticipated this unique opportunity, utilizing both ground-based telescopes and other observational equipment to catch a glimpse of the comet's features during this significant celestial event.

The Arecibo Observatory, located in Arecibo, Puerto Rico, was officially inaugurated as the home of the world’s largest radio telescope. The primary purpose of the telescope was for radio astronomy, atmospheric science, and radar observations of planets. With a 305-meter dish, it was an engineering marvel, reflecting the advancements in technology and science during the early 1960s. The construction was a collaborative effort among NASA, the National Science Foundation (NSF), and Cornell University, marking a significant achievement in both research and exploration of space.

Venus passed in front of the star Regulus, allowing astronomers to study its geometry and atmosphere. Observations were made worldwide, focusing on measurements of the diameter of Venus as it occulted Regulus. This enabled scientists to gather critical data about Venusian atmospheric structure through precise timings and observations.

The Hale Telescope at Palomar Observatory, managed by astronomer Edwin Hubble, achieved first light, marking a significant milestone in optical astronomy. This telescope, featuring a 200-inch aperture, set the standard for large telescopes worldwide, greatly enhancing astronomers' ability to observe celestial objects and phenomena. Its completion was a monumental achievement in the field of astrophysics, making it the largest aperture optical telescope until the construction of the BTA-6 in 1976.
Continue ReadingProposal of 'Pluto' as a Dwarf Planet Name
Vesto Slipher of Lowell Observatory proposed 'Pluto' as the name for a newly discovered dwarf planet in the 1930 Lowell Observatory Observation Circular. The proposition caught public attention, becoming widely adopted in astronomy and popular culture. The choice honored the Roman god of the underworld, reinforcing the mysterious nature of this distant celestial body. The name 'Pluto' was suggested after a poll among the staff at Lowell Observatory, which resonated with both scientific and mythological significance.
