Comet gateway discovered to inner solar system, may alter fundamental understanding of comet evolution
All comets in the solar system might come from the same place
All comets might share their place of birth, new research says. For the first time ever, astronomer Christian Eistrup applied chemical models to fourteen well-known comets, surprisingly finding a clear pattern. His publication has been accepted in the journal Astronomy & Astrophysics. Comets: balls of ice or more? Comets travel through our
