Close-up Hubble images show new details of comet
Tucson AZ (SPX) May 16, 2016
Astronomers using NASA's Hubble Space Telescope captured images of Comet 252P/LINEAR just after a close encounter with Earth on March 21. The close proximity to the comet offered scientists new insights on the body's nucleus. "Because comets are usually only a few kilometers in size, and probably less than 1 kilometer for this comet, reliable measurement of size is best done when they are close to us. That's why the close approach to Earth of this comet offered us a great opportunity to study it," ... read more
