Maximum Perseids activity will occur this year in the early hours of August 12-13 It has two drawbacks: the full moon, which makes it difficult to see weaker meteorites, and increased light pollution.
The Spaniard explained that 10% of the continental surface of the planet is affected by light pollution, but if the brightness of the sky that produces artificial light emission into the atmosphere is taken into account, this percentage increases to 23%. Canary Islands (IAC) in a statement.
The consequences of artificial light emission in the sky affect biodiversity and health, and of course astronomy and future prospects are not at all optimisticlamented the IAC.
However, the Astrophysics Center notes that there are regions that are struggling to reverse this trend, such as in Macaronesia, where institutions from different fields have come together on different projects to fight this type of atmospheric pollution, and determine levels of atmospheric pollution. Light pollution in those areas where it should not reach and take action to stop its progress.
One of these initiatives is to educate the population about the problem of light pollution, and to this end, Friday night 12 to Saturday 13 August on the channel sky-live.tv The Perseid meteor shower will be broadcast live from Pico do Arieiro (Madeira, Portugal) and from the Roque de los Muchachos Observatory in La Palma. This initiative is a collaboration between the IAC and the Portuguese Society for the Study of Ornithology, under the Interreg EELabs and LIFE Natura @ night projects.
“This year, a full moon will make it difficult to see the faintest meteors. That’s why the frequency of the Perseids will be lower – about one every 15 minutes – and We will only notice the most intelligent people, who will still be impressive.”Mikel Serra Ricart, IAC astronomer and EELabs project coordinator commented.
As in previous years It is necessary to find a place away from the urban centers, fix your eyes on a point in the sky and wait patiently to see some traces of light from the Perseidsastronomer advised.
IAC remembers that Like every year around this time, Earth passes through the cloud of dust and rock left behind by Comet Swift-Tuttle in each of its orbits around the Sun.
As a result, on the nights from mid-July to the end of August, the activity of the Persia, known as “Tears of San Lorenzo”.
In Europe, the maximum activity of this meteor will occur on the night of August 12 to 13 When, according to the calculations of standard models, the activity of the Perseids is about 100 meteors / hour, although this year’s full moon will make observing difficult throughout the night.
They are known asshooting stars“To tiny dust particles, some as small as grains of sand, that are shed by comets or asteroids during their orbits around the sun.
The resulting cloud of particles (meteorites), due to melting caused by solar heat, is scattered by the comet’s orbit and traversed by the Earth on its annual journey around the sun.
During this encounter, dust particles disintegrate as they enter the Earth’s atmosphere at high speed, resulting in the appearance of bright streaks known as meteors.
The Perseids derive their name from the constellation Perseus, where their radiation is located (the point in the sky from which they appear to have been born), but their origin is traced back to Comet Swift-Tuttle, which was discovered in 1862, and that is, With an approximate diameter of 26 kilometers, it is the largest object periodically approaching the Earth.
