As far as meteor s go, the Perseids occupy a special place in the skies. They’re so well-known that references to them can even be found in Chinese records from 36 AD. They have an impressive meteoric resume. The name Las Lágrimas de San Lorenzo came into use much later, during Medieval Europe, to honor the Catholic myr.
“Shooting stars” are actually just different-sized picles of dust, some finer than a grain of sand, that comets and asteroids leave behind during their orts around the Sun. The resulting picle cloud (called meteoroids), thawed by the Sun’s heat, disperses in the space around the comet, and every year our planet crosses th it during our ort around the Sun. During this meeting, the dust specks disintegrate upon their high-sd entrance into Eh’s atmosphere, creating those famous streaks of luminescence, referred to scientifically as meteors. From our point of view, all the trajectories of different shooting stars converge into a point of the sky called the radiant. The constellation where that radiant point is found determines the name of the meteor . Thus, the Perseids meteor is found in the Perseus constellation, while the Geminids are found in the Gemini constellation.
A shooting star is nothing more than a small picle that emits light upon hurling high-sd into Eh’s atmosphere due to sudden heat caused by friction
According to standard s, the Perseids’ activity will include about 100 meteors per hour (Zenithal Hourly Rate). Like every year, the Perseids’ reach their peak in the middle of August. For 2016, with maximum visility expected between 13:00 and 15:30 UT/GMT. While they’re active between uly 17 and August 24, the nights of August 12 and 13 will be the ent to observe the . A large number of meteors can also be observed the night before, from late August 11 into the early hours of August 12. A crescent moon, which will disappear for the second half of the night, should not pose a problem for seeing the Perseids; on average, a stargazer will be able to see one every two minutes, including some very bright ones (due to the high sds at which they enter into the atmosphere) for those ing from dark places with clear horizons, far from light contamination.
One of Perseids’ progenitors is the comet Swift-Tuttle, discovered in 1862. In the years around Swift-Tuttle’s perihelion (the point of the ort at which a meteorological body gets closest to the sun, last in 1992 and not expected again until 2126) activity can grow to 400-500 meteors per hour because of the density of the meteoroids that circle and accompany the comet. However, the Perseids are known for their “outbursts” provoked by the gravitational influence of upiter and Saturn on the meteoroid dust clouds created by comets from the past. In 1839, German observer E. Heis recorded for the time the maximum rate of the Perseids: 160 meteors per hour. The last meteor outburst was in 2009, measuring in at 250 meteors per hour. According to the of Russian astronomer Mikhail Masloc, this August we could witness a jump in Perseids activity. “The disturbance coming from upiter will cause the elevated activity of the Perseids this year. The last increase was in 2004, also caused by the Giant planet,” Maslov tells SkyLive.tv.
upiter got the closest it’s been to the ort of the Swift-Tuttle comet in November 2014, when it came within 237 million kilometers. It takes 22 months for the meteoroid current to be pushed towards Eh. Will activity go up in 2016?
Spain has one of the cleanest and clearest skies on the planet from which we can 2016’s Perseids. The European project STARS4ALL, in collaboration with skylive.tv, will offer live streaming of the Perseids. From the Observatories of the Canary Islands, astronomer Miquel Serra Ric will present two programs:
On average, a stargazer can see one shooting star every two minutes, including very bright ones if you from a dark place far from light pollution
Program 1: August 12 19:30-19:45 UT (August 12 21:30-21:34 CEST)
Program 2: August 12 23:12-23:30 UT (August 13 1:15-1:30 CEST)
STARS4ALL and skylive.tv, in addition, will broadcast an image of the sky from El Teide and El roque de los Muchachor for four hours or or on these nights, so that spectators can enjoy the from their s, make their own calculations, or save and edit the age.
Three Spanish Supercomputer centers – Centro Extremeño de Tecnologías Azadas (CETACIEMAT), Consorci de Serveis Universitaris de Catalunya (CSUC) and Instituto de Astrofísica de Canarias (IAC) – will collaborate in distributing the retransmittions th the web portal skylive.tv.
STARS4ALL is a project financed by the European Union’s Program H2020, until the contract number 688135. Eight separate institutions from six European countries under the umbrella of STARS4ALL (UPM, CEFRIEL, SOTON, ECN, ESCP Europe, IAC, IGB and UCM). Its objective is to make the population more aware of the problem of light pollution in many of our cities, emphasizing the importance of taking measures to reduce the contamination as much as possible.
