Look Up! Perseid Meteor Shower Peaks Aug. 11-12

Posted on by .

Make plans now to stay up late or set the alarm early next week to see a cosmic display of “shooting stars” light up the night sky. Known for it’s fast and bright meteors, the annual Perseid meteor shower is anticipated to be one of the best potential meteor viewing opportunities this year.

The Perseids show up every year in August when Earth ventures through trails of debris left behind by an ancient comet. This year, Earth may be in for a closer encounter than usual with the comet trails that result in meteor shower, setting the stage for a spectacular display.

“Forecasters are predicting a Perseid outburst this year with double normal rates on the night of Aug. 11-12,” said Bill Cooke with NASA’s Meteoroid Environments Office in Huntsville, Alabama. “Under perfect conditions, rates could soar to 200 meteors per hour.”

An outburst is a meteor shower with more meteors than usual. The last Perseid outburst occurred in 2009.

How to Watch the Perseids

The best way to see the Perseids is to go outside between midnight and dawn on the morning of Aug. 12. Allow about 45 minutes for your eyes to adjust to the dark. Lie on your back and look straight up. Increased activity may also be seen on Aug. 12-13.

For stargazers experiencing cloudy or light-polluted skies, a live broadcast of the Perseid meteor shower will be available via Ustream overnight on Aug. 11-12 and Aug. 13-14, beginning at 10 p.m. EDT.

LIve Chat and Ustream! 2014 Perseid Meteor Shower

Posted on by .

The annual Perseid meteor shower will peak in the skies over Earth on the night of Aug. 12-13. Despite a bright moon, there should still be a good show from this prolific shower. Projected peak rates are 30-40 meteors/hour. Much of the world can see Perseids any time after full dark, with peak viewing projected early on the morning of Aug. 13 (3-4 a.m., your local time).

Dr. Bill Cooke, Rhiannon Blaauw and Danielle Moser of the NASA Meteoroid Environment Office will take your Perseid questions via live web chat. The chat module will appear on this page on Aug. 12 at 11 p.m. EDT (Aug. 13, 3:00 UTC). A Ustream view of the skies over Marshall Space Flight Center will be embedded on this page on Aug. 12 at 9:30 p.m. EDT (Aug. 13, 1:30 UTC).

Perseids Meteor Shower Lights Up the Sky

Posted on by .

Marshall scientist Bill Cooke and his team, from the Meteoroid Environment Office at Marshall Space Flight Center, watched the sky during the peak of the Perseid meteor shower. The team used the Marshall meteor cameras the evening of August 12 and into the early morning August 13 to capture images of the Perseids.

The Perseids have been observed for about 2,000 years. The source of the annual meteor shower is the debris trail left behind comet Swift-Tuttle. Each year in August, the Earth passes through a cloud of the comets debris. These bits of ice and dust burn up in the Earth’s atmosphere. Most of the Perseid meteors that we observe now were ejected from Swift-Tuttle about 1,000 years ago.

Cooke and his team answered questions about the Perseids during an Up All Night with NASA web chat. You can read a transcript of the web chat (PDF, 550 Kb) to learn more about the Perseids: what creates them, their composition, how old they are, how fast they travel and other fascinating facts.

NASA Catches First Glimpse of This Year's Perseid Meteor Shower

On the night of July 26, allsky cameras of the NASA fireball network detected three Perseid meteors in the skies above Tennessee and Alabama. The first seen by the cameras this year, these meteors are the “advance guard” of the Perseid meteor shower, which will peak on the night of Aug. 12.

Want to watch the Perseids with NASA astronomy experts? Make plans to join astronomer Bill Cooke and his team from NASA’s Marshall Space Flight Center for an “up all night” Web chat on the night of Aug. 12 and into the early morning of Aug. 13. You can ask your questions and also view a live Ustream view of the Perseids in the skies over Huntsville, Ala.

If you or another astronomy group is planning a live Web view of the Perseids, please leave us a comment and let us know — we’ll feature a link to your live Perseids Web stream!
