There are also times throughout the year when people are more likely to see shooting stars. 'All you've got to do is go outside, find a nice dark spot, lie flat on your back and look up,' Bill Cooke, head of NASA's Meteoroid Environment Office at the Marshall Space Flight Center in Alabama, previously told Live Science. Why are there no purple or green stars? How much would you weigh on other planets? But he is confident that a person who deliberately and purposefully watches the sky on a clear night from a location 'untarnished by artificial light' will be able to see 'five to 10 meteors per hour,' if not more.

Krupp also believes that many of us are guilty of being 'busied by other things' and, as a result, often don't take the time to look at and admire the sky. Once fully operational, there could be 42,000 Starlink satellites orbiting Earth, something that has led the International Astronomical Union to create the Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference to 'mitigate the negative impact of satellite constellations.' Starlink, Elon Musk's internet-enabling satellite network, is also causing issues for astronomers. and Europe, it's estimated that 99% of people live under some degree of skyglow. Department of Energy defines as 'an increase in the apparent brightness of the night sky that can serve to reduce visibility for astronomical observation.' In the U.S. According to the ' World Atlas of Artificial Night Sky Brightness,' around 80% of the world's population lives under 'skyglow,' which the U.S. Unfortunately, and largely due to human activity, pristinely dark skies are increasingly hard to find. (You can see a comprehensive list of the world's best dark sky sites at this page from the International Dark-Sky Association.) Some of the best dark sky areas include Northumberland National Park in England, the largest gold-tier dark sky park in Europe the Central Idaho Dark Sky Reserve, the first gold-tier dark sky preserve in the United States and the Atacama Desert in Chile, which contains La Silla Observatory, home to some of the world's most powerful telescopes.

Since 2001, the International Dark Sky Places conservation program, run by the International Dark-Sky Association (IDSA), has encouraged communities to 'preserve dark sites through responsible lighting policies and public education.' The IDSA also dictates whether a site can officially be called a 'dark sky,' and has, to date, awarded 195 areas around the world dark sky status.Ĭertain sites have 'gold-tier dark sky' status, which is the IDSA's highest possible rating. Dark sky sites have very low levels of light pollution and allow uninterrupted views of the night sky. If you want to see shooting stars, it's important to find a dark sky location, Krupp said. However, Earth also intercepts many smaller particles that are too faint to be detected by the unaided eye, Krupp noted. The number of meteors visible to the unaided eye under a truly dark sky in a 24-hour period all over Earth is estimated to be 25 million, according to a University of Oregon report. Most extraterrestrial rubble that collides with the atmosphere is 'very small, typically the size of a grain of sand,' he added. 'Meteors occur all of the time, all over the Earth, but are only seen at night,' Krupp said. On rare occasions, meteor showers have been known to light up the entire sky.So, how common are shooting stars? How often do these flashy space rocks come into contact with Earth's atmosphere, and what's the best way to see them? The number of shooting stars then increases to perhaps 100 per hour.

At certain times of the year, the Earth passes through a comet trail. On a clear night, if you stare at the sky for long enough, you will see one of these meteors, or shooting stars. These streaks are called meteors, often nicknamed 'shooting stars' or 'falling stars'. As the dust grains burn up, they leave bright streaks of light across the night sky. The sand-sized grains of dust sometimes slam into the thin air that surrounds the Earth, called the atmosphere, where they get hot very quickly. These comets leave many trails of gas and dust behind them. There are several hundred comets that spend most of their lives among the planets of the inner Solar System.
