Lost 19th Century World “Erased” from Our Solar System: The Story of Planet Vulcan

In 1846, Urbain Le Verrier, a talented astronomer and mathematician, made an intriguing discovery while studying Uranus’ orbit. The planet seemed to deviate slightly from what Newtonian gravity predicted. Le Verrier proposed the existence of an unseen planet beyond Uranus, and his calculations led to the discovery of Neptune.

But this was just the beginning of Le Verrier’s astronomical quest. He then turned his attention to Mercury, which proved to be a challenging planet to observe due to its proximity to the Sun. Despite his efforts, Mercury’s orbit did not align with Newtonian physics. Le Verrier postulated the presence of another planet, which he named Vulcan, responsible for the mysterious wobbles in Mercury’s orbit. His fellow astronomers reported sightings of Vulcan, but these observations were inconclusive and open to interpretation.

The idea of Vulcan persisted for about 70 years, with occasional reports and attempts to spot it during solar eclipses. However, the elusive planet remained just that – elusive. The scientific community at the time considered Vulcan a real possibility, yet it never gained widespread recognition like the other eight planets.

Record Ultra-Long Gamma-Ray Burst Set Off Telescope Twice – And The Reason Is Cataclysmic

Gamma-ray bursts , remarkable displays of energy, vary in duration from fractions of a second to several minutes. Among them are ultra-long gamma-ray bursts, lasting over 1,000 seconds. One such event, GRB 220627A, intrigued scientists as it triggered telescopes twice, separated by a 600-second gap, leading to questions about its origin and nature.

The Most Distant Ultra-Long Gamma-Ray Burst: GRB 220627A, lasting 1,095 seconds, became the most distant ultra-long gamma-ray burst ever recorded, with its light traveling 11.6 billion years to reach us. Researchers seized the opportunity to study its afterglow using different telescopes to understand if long and ultra-long gamma-ray bursts originate from the same event.
