Chicxulub Impactor that Killed the Dinosaurs Was A Comet Fragment, Not An Asteroid, Harvard Researchers Theorize
Harvard astrophysicists proposed a new model showing that the Chicxulub impactor — the celestial body responsible for the mass extinction of the dinosaurs — could have been of cometary, rather than asteroidal origin, in a study published in Scientific Reports on Monday.
Researchers at Harvard, MIT, and other institutions used a new telescope to confirm the existence of the first Earth-sized planet outside our solar system in a habitable zone, a step toward understanding how life formed on Earth and could form in other solar systems.
Paul Martini, an astronomy professor at Ohio State University, discussed the mystery of cosmic acceleration at a Radcliffe Fellows event Wednesday.
