Dec 3, 2013 — Imagine stepping into an elevator and bumping into your greatest hero. What would you say? Commentator Adam Frank had this happen with one of the 20th century's greatest astronomers, a seer of sorts.
Dec 2, 2013 — There were hopes over the weekend that ISON might have survived its close encounter with the sun. But "with more than a little sadness," the space agency says, "we have to declare the comet lost."
Nov 28, 2013 — Most of ISON, a huge comet formed at the birth of the solar system, apparently did not survive Thursday's encounter with the sun, NASA said. Scientists detected the comet last year and had hoped to continue studying it for information to be mined from its "primordial ices."
Nov 22, 2013 — When astronomers spotted Comet ISON in 2012, some christened it the "Comet of the Century." It initially failed to live up to the hype. But this month, ISON blazed brighter and sprouted several tails. Astronomers like Andrew Fraknoi are following the comet as it scrapes past the sun, where it could be destroyed—or emerge, even more spectacular than before.
Nov 21, 2013 — By putting light sensors inside a giant ice cube that's a mile beneath the South Pole, scientists detected 28 neutrinos from beyond the solar system. It's just a start - but researchers hope the work could eventually yield a way to see through debris clouds to the core of exploding stars.
