For the 50th anniversary NASA has released some beautiful Panoramas pictures of Apollo missions.
It is coming the moment of Leonid meteor shower that we have an opportunity to watch it late Saturday night and into Sunday morning this year. This meteor shower is always occurring in mid-November. According to the data of NASA an average of about 15 meteors per hour streak across the night sky during the shower’s yearly peak.
To find a viewing site is site far away from city or street lights.
“It is actually better to view the Leonids away from the radiant: They will appear longer and more spectacular from this perspective,” NASA indicates.
In the night sky, it will appear like the meteors are coming from the constellation Leo, which gives the shower its name. However, this is neither their origin nor the best part of the sky to look for them.
“In less than 30 minutes in the dark, your eyes will adapt and you will begin to see meteors,” the space agency writes.
“These outbursts of meteor activity are best seen when the parent object, comet 55P/Tempel-Tuttle, is near perihelion (closest approach to the sun). Yet it is not the fresh material we see from the comet, but rather debris from earlier returns that also happen to be densest at the same time,” writes the American Meteor Society.
The Leonid meteor shower is a prolific meteor shower related to the comet Tempel–Tuttle. The Leonids receive their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from that point in the sky. Earth moves through the meteoroid stream of particles left from the passages of a comet. The Leonids are a fast moving stream which encounter the path of Earth and impact at 72 km/s. Larger Leonids which are about 10 mm across have a mass of half a gram and are known for generating bright meteors. An annual Leonid shower may deposit 12 or 13 tons of particles across the entire planet․
