When the earth traverses the trail of debris left behind by a comet, parts of this debris catch fire in our atmosphere and sweep across the sky with a blaze of 3,000 degrees Celsius. On the nights of July 27th and 28th, you can see this heavenly show during the annual peak of the Delta Aquariid Meteor Shower.
The shower may not be quite as spectacular as the Perseid Meteor Shower, which is yet to come 11th to 13th August, but it's worth staying Friday night or Saturday to look up to the sky.
How do you like it? The meteorites seem to emanate from the star Delta Aquarii, in the constellation Aquarius (which has the shape of a man pouring out a pitcher of water). Use a smartphone app like Sky Guide to find out where to look.
Aquarius will rise in the southeastern sky in the late evening (after 11 pm). The meteorites will be easier to detect the later it gets at night as Delta Aquarii rises higher and higher.
NASA notes that this meteor shower produces around 20 meteors per hour at the top. You do not have to look directly at Delta Aquarii to see them, as they shine in all directions across the sky. However, a bright full moon could hide your chance to see it.
Although the show reaches its peak on July 27th and 28th, Earthsky reports that some Delta Aquarid meteors are seen every night until the end of August, and that they can best be seen after midnight
You can not see the meteors, at least you get a great view of Mars. This is because on July 27, the sun, the earth and the planet Mars will come together for a two-year treatment called Mars in Opposition . It's a chance to see the red planet in big, bright details in the night sky. The opposition also occurs only a few days before the Earth's and Mars's closest approach – July 31. As a result, Mars appears slightly larger in the sky than usual.
In any case (unless you expect clouds and rain), you'll certainly find something cool when you star in the stars on Friday.
