Hey Space Placers!
66 million years ago an asteroid about 9 miles across hit the waters in the Gulf of Mexico and unleashed hell on Earth that killed off the dinosaurs.
Planetary defense using telescopes and spacecraft to detect killer asteroids and comets followed by launching of an impactor like NASA recently did with its DART mission, should prevent an impact like this from happening again.
Here is the latest photograph from Hubble Space Telescope showing the debris tail from that DART mission impact.
