NASA says the Geminids are the Best Meteor Shower of the Year

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – NASA says the Geminids are widely recognized as the best annual meteor shower a stargazer can see, occurring between December 4th to December 17th, 2020 with the best nights for viewing on December 13th and 14th.

The parent of the Geminids is 3200 Phaethon, which is arguably considered to be either an asteroid or an extinct comet. When the Earth passes through trails of dust, or meteoroids, left by 3200 Phaethon, that dust burns up in Earth’s atmosphere, creating the Geminid meteor shower.

NASA releases images of Phaethon Asteroid taken by Arecibo Radar

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After several months of downtime since Hurricane Maria struck the island of Puerto Rico, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its December 2017 close approach to Earth.

The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal (roughly ball-shaped) and has a large concavity, or depression, at least several hundred meters in extent near its equator, and a conspicuous dark, circular feature near one of the poles. Arecibo’s radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel.

These radar images of near-Earth asteroid 3200 Phaethon were generated by astronomers at the National Science Foundation's Arecibo Observatory on Dec. 17, 2017. Observations of Phaethon were conducted at Arecibo from Dec.15 through 19, 2017. The encounter is the closest the asteroid will come to Earth until 2093. (Arecibo Observatory/NASA/NSF)

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As arctic air and record cold sweeps across the USA, amateur astronomers are looking at their calendars with a degree of trepidation. A date is circled: December 14th. And below it says: “Wake up at 4:00am for the Geminid meteor shower.”

“It’s going to be cold,” says Bill Cooke of NASA’s Meteoroid Environment Office. “But that is the best time to see the 2013 Geminid meteor shower.”

NASA says look at the skies December 13th-14th for annual Geminid Meteor Shower

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – The annual Geminid meteor shower will peak on the night of December 13th-14th, 2013. NASA astronomer Bill Cooke, along with Danielle Moser and Rhiannon Blaauw from his team of experts, will be on hand to answer questions via a live web chat on December 13th from 10:00pm until 2:00am CST.

A live Ustream feed of the skies over NASA’s Marshall Space Flight Center will also be embedded on this page on the night of the chat.

NASA’s STEREO probes discovers Rock Comet’s Tail

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Astronomers have long been puzzled by a certain meteor shower.

Every year in mid-December the sky fills with flashes of light shooting out of the constellation Gemini. The Geminids are fast, bright, and reliable. They never fail to show up and many observers count them as the finest meteors of the year.

But where do they come from? That is the puzzle.

NASA reports Geminid Meteor Shower to peak on December 13th and 14th

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Every year in mid-December, astronomers look up in the sky and witness a mystery. It announces itself with a flurry of shooting stars. For several nights in a row, dozens to hundreds of meteors per hour cut across the glistening constellations of winter, each one a little puzzle waiting to be solved.

“It’s the Geminid meteor shower–set to peak on December 13th and 14th,” says Bill Cooke of NASA’s Meteoroid Environment Office. “Although the Geminids come every year, we still don’t fully understand them.”
