A healthy person usually has a platelet count of 150,000 to 400,000. You have thrombocytopenia if your number falls under 150,000. If you're wondering what the long name means, here's how it breaks down: thrombocytes are your platelets and penia means you don't have enough of something.
The Perseids are active from July 13 to August 26, according to the American Meteor Society, a nonprofit scientific organization that supports the research of astronomers, but the meteor shower peaks between August 12-13.
Armchair astronomers, get ready. One of the best meteor showers of the year is coming in just a few days. The Perseid meteor shower will be lighting up the night sky starting Wednesday. The annual display could fill the sky with as many as 100 meteors per hour during its peak, according to NASA. This year the shower is peaking just before a new moon, so meteors will appear especially bright on the background of darkness.
