Violent comet crashes are occurring around a star easily visible to sky-watchers, astronomers report. The star is one already known to harbor a burgeoning solar system. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) Telescope in northern Chile announced this week that they have found a giant clump of carbon monoxide gas in the dusty disk...

Comets dominate the pre-dawn skies and their flybys of neighboring planets offer observing challenges for early bird sky-gazers.  Comet ISON Brightens. Late last week Comet ISON began to wake up and now shines ten times brighter than it did just a week earlier. At magnitude 5.5 it has finally reached naked-eye levels from dark locations, according...

Backyard astronomers in the Northern Hemisphere get an eyeful this week, when four comets will be visible with binoculars or small telescopes in the early morning sky. First up, the most famous of the bunch is Comet ISON, which is currently speeding towards its close encounter with the sun on November 28. While it has...

The Earth’s moon plays hide and seek with distant stars and our sun this week, and the nighttime sights include a double comet show in the pre-dawn skies. Lunar Trio. In the early morning hours of Tuesday, October 29 the moon will form a stunning triangular pattern with ruddy Mars and blue-white star Regulus in...

A thought-provoking new study is bolstering the notion that comets raining down on Earth billions of years ago may have seeded our young planet with the organic building blocks of life. Through powerful computer simulations of comet impacts of various sizes, astronomers have found that it is possible that complex organic molecules  may have hitched...
