Members of the cult believed that their bodies were merely containers that could be abandoned in favor of a higher physical existence, (opens in new tab) reported. Heaven's Gate was an end-times cult led by Marshall Applewhite, a former music professor who advocated sexual abstinence and who had undergone castration. "The surface of Hale-Bopp's nucleus must be an incredibly dynamic place, with 'vents' being turned on and off as new patches of icy material are rotated into sunlight for the first time," said Harold Weaver, a Johns Hopkins University astrophysicist who led the Hubble study. What surprised the scientists observing Hale-Bopp the most was an outburst of dust streaming from the comet's nucleus in quantities at least eight times as much as the average observations of previously observed comets. NASA studied the comet with the Hubble Space Telescope and reported that the comet's nucleus is "huge," (opens in new tab) at 19 to 25 miles (30 to 40 km) across.

Professional telescopes swung to watch the comet as it approached. It wasn't only amateurs watching the show, of course. "A Hale-Bopp homepage set up at NASA's Jet Propulsion Laboratory was logging more than 1.2 million visitors a day over Easter weekend and had set up two mirror sites."

"There are a multitude of websites containing information on Hale-Bopp they are attracting so many visitors that they are causing a traffic jam on the Internet," Scientific American wrote in March 1997 (opens in new tab). Hale-Bopp comet causes internet traffic jamĭuring Hale-Bopp's months-long approach to Earth, descriptions of the comet drummed up interest in newspapers and on the internet, which at the time was a young but growing public phenomenon. Objects in the Oort Cloud are so far away from the sun that gravitational perturbations from passive stars, molecular clouds or even tidal forces from the Milky Way can be enough to dislodge an object from the icy reservoir (opens in new tab) and send it on a highly elliptical orbit around the sun. One AU is the distance from Earth to the sun and is equivalent to about 93 million miles (150 million kilometers). Hale-Bopp likely originated - like most long-period comets - from the Oort Cloud, a spherical collection of ice objects located approximately between 2,000 and 100,0000 Astronomical Units (AU) from the sun. Long-period comets usually exhibit highly elliptical orbits making them less predictable than short-period comets.

The image was captured through a red filter and shows sunlight reflected from the dust in Hale-Bopp's coma. The images were taken at the Danish 1.5-meter telescope with the DFOSC multi-mode instrument. Where did Hale-Bopp come from?Ĭomet Hale-Bopp was observed in November 1996 by Hermann Boehnhardt of the Astronomical Institute of the Ludwig-Maximilian-University in Munich. Hale-Bopp was many times farther away than Hyakutake but still appeared much brighter. Astronomers still had the bright Hyakutake comet fresh in their minds at the time as it just passed by Earth in 1996.

(By comparison, the sun is 93 million miles, or 150 million km, from Earth). 22, 1997, at a distance of about 120 million miles (193 million kilometers). "It's been kind of nerve-racking to sit through all those months wondering if the comet would fizzle," Hale told Time.Īccording to NASA (opens in new tab), Hale-Bopp's closest approach to Earth occurred on March. While they expected the comet would be bright when it arrived close to Earth, predictions are tricky when it comes to comets - they are essentially just balls of ice and dust that erupt in ways that are hard to anticipate. Amazing photos of Comet Leonard in the night skyĪstronomers were astounded at how bright the comet, officially designated C/1995 O1, appeared even from its great distance away. Wild idea: Tagalong spacecraft could watch a comet form- Comets' heads may be green, but never their tails
