Photographer Joshua Tam captured a mysterious spiral star glowing above the Yerkes Observatory in Wisconsin while trying to capture “shooting stars” from the Perseid meteor shower.
While watching the Perseid meteor shower's “shooting stars,” viewers across a large swath of the United States recently witnessed a stunning sight: a huge spiral of ghostly white light. While we know what they saw, experts aren't sure what it actually was.
On Tuesday night (August 12) at about 10:30 p.m. ET, during the peak of the Perseid meteor shower, a faint point of light appeared in the skies over parts of the United States and Canada, then quickly grew larger and turned into a giant vortex of light. The phenomenon was visible for about 10 minutes before it disappeared. It was seen in at least 10 states, including Maryland, New York, New Jersey, Illinois, Ohio and Nebraska.
Photographer Joshua Tam captured this otherworldly spectacle above the Yerkes Observatory in Williams Bay, Wisconsin (above), while astrophotographer Dan Bush captured dramatic images of the spiral moving across the night sky in Albany, Missouri (below).
