Northern hemisphere observers have this month and next to get their best look at Rosetta's comet, 67P/Churyumov-Gerasimenko.
Comet C/2014 Q1 PanSTARRS has been skirting the northern horizon since mid-June. Now it's ready to dip Down Under, where it may be visible with the naked eye in evening twilight.
Participate in a world-wide campaign to observe and photograph Comet 67P/C-G as it approaches and recedes from the Sun with Rosetta in tow. Your observations matter.
The new Comet Lovejoy, C/2014 Q2, should brighten from 5th to 4th magnitude from late December through January as it climbs into excellent viewing position for the Northern Hemisphere, high in the dark winter sky.
A new Comet Lovejoy, C/2014 Q2, is heading our way. It may brighten to 5th magnitude from late December through much of January as it climbs into excellent viewing position for the Northern Hemisphere, high in the dark winter sky.
Thanks to a generous bequest, each year amateur astronomers earn a beautiful plaque and a cash prize for discovering one or more comets.
