Discovery Images of Dwarf Planet Eris Captured
Images of the dwarf planet Eris were successfully taken using the powerful CCD camera of the Samuel Oschin Telescope at Palomar Observatory. These images revealed a distant celestial body located in the scattered disc region of the solar system, which is beyond Neptune. The discovery of Eris, initially designated 2003 UB313, has implications for our understanding of celestial bodies in the outer solar system. Observational studies began in 2003, but the confirmed imaging occurred in 2005, leading to its recognition as a significant trans-Neptunian object.

Pluto crossed Neptune's orbit in February 1999 during a celestial event that marked the end of a nearly 20-year period where it was closer to the Sun than Neptune. This astronomical occurrence significantly affects the dynamics of the solar system by shifting the boundaries of orbits, influencing gravitational interactions and solar system configurations. As Pluto moves into this phase, it is not expected to interact with Neptune's orbit again until 2231, which highlights the unique and fluctuating nature of these distant celestial bodies in their elliptical orbits.

Voyager 2 spacecraft made its closest approach to Neptune, the last planet in the Solar System at the time. This significant event occurred on August 25, 1989, as Voyager 2 flew within 4,800 kilometers of Neptune's cloud tops. The spacecraft captured stunning images and data, providing the first close-up view of Neptune and its moons, vastly expanding our understanding of this distant planet and its features, including Neptune's Great Dark Spot, a massive storm system.

Pioneer 10 became the first man-made object to leave the central Solar System when it successfully passed beyond the orbit of Neptune. Launched in 1972, its mission was to gather data about Jupiter and the outer planets. As it traversed the vastness of space, Pioneer 10 transmitted valuable information, including insights on cosmic rays, magnetic fields, and the asteroid belt. This milestone marked a significant achievement in space exploration, demonstrating humanity's ability to reach beyond the boundaries of our planetary neighborhood.

Pluto moved inside Neptune's orbit in 1979, a rare astronomical event due to its elliptical orbit. This positioning brought the two celestial bodies closer, allowing scientists to study their interactions. Both Pluto and Neptune were discovered in the 20th century, and this alignment highlighted the unique characteristics of their orbits and the dynamics of the solar system.

NASA successfully launched the Voyager 2 spacecraft on a mission to explore the outer planets of the solar system. Launched from Cape Canaveral, Florida, Voyager 2 followed Voyager 1, embarking on a journey to gather data about Jupiter, Saturn, Uranus, and Neptune. This mission was significant for its ambitious plan to conduct flybys of multiple planets, enabling a better understanding of the outer solar system and deep space phenomena.

Clyde Tombaugh, an American astronomer, made a groundbreaking discovery while examining photographs taken in January. Working at the Lowell Observatory in Arizona, he was searching for a ninth planet beyond Neptune. His meticulous analysis of photographic plates ultimately led to the identification of a new celestial body, which would later be named Pluto, marking a significant milestone in astronomy.

William Lassell, an English astronomer, discovered Triton, Neptune's largest moon, shortly after the discovery of Neptune itself. Using his telescopic advancements, Lassell observed Triton from his observatory in England, marking a significant addition to our understanding of the solar system. This moon, characterized by its unique retrograde orbit, is believed to have been captured by Neptune’s gravity rather than formed alongside it. The discovery was a remarkable feat of observational astronomy in the 19th century.

Astronomers Urbain Le Verrier, John Couch Adams, and Johann Gottfried Galle collaborated to confirm the existence of Neptune, using mathematical predictions based on observed irregularities in Uranus's orbit. On this day, Galle successfully located the planet with a telescope at the Berlin Observatory, solidifying their calculations and advancing the field of astronomy significantly.
