Scientists found cosmic dust on
city rooftops for the first time.
500 grains of 4.6 billion-year-old
cosmic dust were identified after
filtering nearly 700 lbs of sludge from
gutters in Oslo, Paris, and Berlin.
We’ve known since the 1940s that
cosmic dust constantly falls through
the atmosphere, but no one has
actually been able to locate it until now.
These 3,000-year-old Egyptian
hieroglyphics may resemble planes,
helicopters, and UFOs, but experts
agree it’s just an effect caused by
erosion. The stone was once filled with
plaster and re-carved during the reign
of a new pharaoh. Over time, erosion
partly revealed both inscriptions, and
the overlapping hieroglyphs created
new shapes. SourceSource 2Source 3
