A comet not seen since Neanderthals walked the Earth is set to make a return trip - and astronomers have shared the first detailed image of the 'cosmic snowball.' Formally known as C/2022 E3 (ZTF), the comet orbits the sun every 50,000 years and is set to make its closest approach to our planet on February 1, 2023.... ....The comet is currently 117 million miles from Earth and is set to reach the sun on January 1, loop around and make its closest approach to our planet. And E3 will be the first comet seen to the naked eye since...

Explanation: Named for a forgotten constellation, the Quadrantid Meteor Shower is an annual event for planet Earth's northern hemisphere skygazers. It usually peaks briefly in the cold, early morning hours of January 4. The shower's radiant point on the sky lies within the old, astronomically obsolete constellation Quadrans Muralis. That position is situated near the boundaries of the modern constellations Hercules, Bootes, and Draco. Many of this year's Quadrantid meteors were dim, but the one captured in this north-looking view is bright and easy to spot. In the foreground is the Maurice River's East Point Lighthouse located near the southern...

If you enjoy the sight of "shooting stars" then make plans to be out looking skyward during the predawn hours on Wednesday (Jan. 4) when a strong display of Quadrantid meteors may appear. This first meteor shower of the year may end up being one of the best of 2012. To paraphrase Forrest Gump: The Quadrantid meteor shower is like opening up a box of chocolates; you never know what you're going to get! Indeed, the Quadrantids are notoriously unpredictable, but if any year promises a fine display, this could be it. Peak activity is due to occur early on...

QUADRANTID METEOR ALERT: Earth is about to pass through a narrow stream of debris from shattered comet 2003 EH1, source of the annual Quadrantid meteor shower. "Peaking in the wee morning hours of Tuesday, Jan. 4, the Quads have a maximum rate of about 100 per hour (varies between 60 and 200)," says Bill Cooke of NASA's Meteoroid Environment Office. "What makes this year so special is that the Moon is New on the night of the peak, so there will be no interference from moonlight." PARTIAL SOLAR ECLIPSE: After the meteor shower, observers in Europe, northern Africa, the Middle...
