Perseid meteor shower

The Perseid meteor shower has begun. While the best viewing typically occurs after midnight when your location faces forward into the meteor stream, this year’s full moon is bright enough to interfere with visibility. To get around this, it's best to start watching at dusk, before the moon rises. The Perseids are tiny bits of ice from comet Swift Tuttle, disintegrating as they enter Earth's atmosphere. About one in 20 meteors, however, is a background meteor from the asteroid belt, which can survive their fiery descent. These "sturdy" meteors can even crash through roofs at speeds of up to 250 miles per hour. Despite the rarity of such impacts, insurance usually covers the damage.

    A rare cosmic pairing
    Bob Berman
    On Wednesday, July 23, we saw a rare cosmic pairing as the Moon passes unusually close to Spica, the brilliant blue star in Virgo. Thanks to a unique tilt in the Moon’s orbit — an event that won’t repeat until 2043 — this striking alignment becomes visible to the naked eye. Learn why Spica shines so hot and bright, and how to pronounce its name the right way. Look up between 9:30 and 10 p.m. for a glimpse of this fleeting spectacle.

    Hot times
    Bob Berman
    This week marks the statistically hottest time of the year—a fitting moment to reflect on the nature of heat. At its core, heat is just atomic motion: room temperature atoms zip around at 1,000 mph, and even freezer-chilled ones aren't far behind. Combustion happens when atoms move fast enough to sustain a reaction, with ignition temperatures varying by substance—wood around 400°F, gasoline at 495°F, and paper at the symbolic 451°F. Pyrophoric materials like sodium don’t even need a spark to ignite. Ultimately, heat is motion—your feverish 102°F body is just your molecules moving faster than usual. Tune in this week to hear more about atomic speed.

    Radiation on Mars
    Bob Berman
    Twelve years ago, NASA's Curiosity rover journeyed to Mars with instruments that measured space radiation for the first time en route. The findings were sobering: astronauts would face radiation doses equivalent to a full-body CT scan every few days—raising cancer risks by 3–4% on the trip alone. Most of this came from galactic cosmic rays, which spacecraft walls can’t block. And this didn’t even include the added threat of solar storms. To send humans safely to Mars, solving the radiation challenge is essential.
