Meteor shower over the town of petworth
The annual firework display in the sky known as the Perseids meteor shower – one of the most spectacular ‘shooting stars’ reached a peak on Monday evening and Tuesday morning, astronomers said.
Each year between July 17 and August 24, the meteor shower is active as the Earth’s orbit around the Sun passes through the cosmic material trailing from the tail of comet Swift-Tuttle, which last passed through our vicinity in 1992.
On Monday evening and Tuesday morning observers saw bright streaks of light flash through the sky at a rate of about one or two a minute just like the image Anthony captured through his camera lens above Petworth.
Meteors, also known as shooting stars, are small particles of material that collide with the Earth’s upper atmosphere at speeds of 36 miles per second, vaporising into flashes of light.
The Perseids meteor shower gets its name because it appears to originate from a ‘radiant’ in the constellation of Perseus.
Extreme heat waves
such as those that hit the US in 2012 and Australia in 2009—dubbed
three-sigma events by the researchers—are projected to cover double the
amount of global land by 2020 and quadruple by 2040.
Meanwhile, more-severe summer heat waves—classified as five-sigma events—will go from being essentially absent in the present day to covering around three per cent of the global land surface by 2040.
The new study, which has been published today, Thursday 15 August, in IOP Publishing's journal Environmental Research Letters, finds that in the first half of the 21st century, these projections will occur regardless of the amount of CO2 emitted into the atmosphere.
