Comet Neowise, two meteor showers and the ISS: Skywatching opportunities abound in next few weeks - National Post

Depending on where you look, you may encounter fewer meteors, however. Viewers in the Northern Hemisphere will see shooting stars emanate from the shower’s “radiant” point in the southern sky, meaning the best meteors with the longest tails will be most readily visible in the east and west.

A much more spectacular meteor shower — among the year’s most prolific — will pepper the skies with a spattering of bright shooting stars and “fireballs” come mid-August. The Perseid meteor shower peaks the night of Tuesday, Aug. 11. Dozens of shooting stars could be visible beneath a clear sky every hour.

Perseid meteors zip across the sky at 37 miles per second. Their diaphanous tails can appear white, orange, yellow, pink, turquoise and even violet, lingering in the sky for a few seconds. The rainbow spectrum of colors come from the combustion of magnesium, sodium and iron.

The only fly in the ointment? This year’s Perseids will be competing with a 47 percent illuminated moon, which could outshine some of the fainter meteors.

In the meantime, you can also keep an eye out for the International Space Station, a scientific laboratory some 254 miles above the earth’s surface. The International Space Station will occasionally be visible as it cruises overhead at speeds of about five miles per second.

Viewing times and directions will vary according to your location; for the latest listings specific to your local area, check here:
