Strange Universe With Bob BermanThe 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.

Strange Universe With Bob BermanWe explore the quirky world of units—from the 1999 Mars Orbiter disaster caused by a metric vs. imperial mix-up to the colorful ways we measure everything from chili pepper heat to cotton and paper. You'll learn why U.S. territorial waters were once based on the range of a cannon shot, how Fahrenheit’s scale reflects geometric symmetry, and why a "barrel" of oil isn’t the same as a barrel of beer. With oddball units like skeins, quires, and cords still in use, maybe it’s finally time we all bolted over to metric!

Strange Universe With Bob BermanOn 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.

Strange Universe With Bob BermanTime to explore a radical new idea shaking up our understanding of the cosmos: what if dark matter doesn’t exist at all? Some European astronomers propose that the Milky Way and Andromeda galaxies may have already collided once in the distant past—a theory that challenges long-held beliefs about gravity and the mysterious dark matter thought to hold galaxies together. Instead, they point to a bold alternative called MOND (Modified Newtonian Dynamics), which suggests gravity behaves differently on cosmic scales. If true, this could rewrite everything we know about the structure and evolution of the universe.
