Collision Solved the Mystery of the Geminid Meteor Shower.

NASA scientists have used data from the Parker Solar Probe to determine that the Geminid meteor shower, which originates from asteroid 3200 Phaeton, was likely formed by a catastrophic event such as a collision or explosion that broke apart a much larger body, possibly a comet. The mass of the Geminids is estimated to be on the order of or larger than that of the parent body, which suggests the stream was formed in a possibly catastrophic event that shed a large amount of mass in a relatively short period of time approximately 2,000 years ago.

Princeton Researchers Uncover Violent Origins of Geminids Meteor Shower.

Researchers at Princeton University have used data from NASA's Parker Solar Probe to deduce that a violent, catastrophic event, such as a high-speed collision or a gaseous explosion, likely created the Geminids meteoroid stream, which unusually originates from an asteroid rather than a comet. The Geminids meteoroids light up the sky as they race past Earth each winter, producing one of the most intense meteor showers in our night sky. The findings deepen our understanding of the composition and history of asteroids and narrow down hypotheses about this asteroid's composition and history that would explain its unconventional behavior.

Super Typhoon Mawar poses catastrophic threat to Guam

Typhoon Mawar, potentially the strongest tropical cyclone to hit Guam in decades, is expected to make a direct hit with winds as strong as 140 mph, equivalent to a Category 4 hurricane. The typhoon warning has been issued for the U.S. island territory, and residents are advised to seek shelter immediately. Rainfall could reach as high as 20 inches, and storm surge is forecast to reach as high as 25 feet. President Joe Biden declared an emergency in Guam due to Mawar and ordered federal assistance to support the response to the typhoon.
