Perseids Are Already Appearing in the Huntsville Sky

Posted on by .

This composite image shows the meteors detected by the NASA All Sky Fireball Network station here in Huntsville, Alabama this morning.   The majority of the meteors are Perseids, but a handful belong to the Northern Delta Aquariid, Southern Delta Aquariid, Alpha Capricornid, and Southern Iota Aquariid meteor showers that are also active.

NASA Marshall to Host Ustream Event About Perseid Meteor Shower August 12; Experts to Answer Questions Online

Posted on by .

Perseid Meteor Shower Banner

Enjoy a summer evening of sky watching as the annual Perseid meteor shower peaks on the night of August 12 through the morning of August 13. Join meteor experts from NASA’s Marshall Space Flight Center for live Ustream commentary during the shower. Perseid meteor rates can get as high as 100 per hour, with many fireballs visible in the night sky

How to View the Perseid meteor shower

The best opportunity to see the Perseid meteor shower is during the dark, pre-dawn hours of August 13. The Perseidss streak across the sky from many directions. For optimal viewing, find an open skyline, where you can view the horizon without obstructions, such as buildings or trees.  Try to view the Perseids as far away from artificial lights as possible. The darker the sky, the better viewing experience you can have. Lie on the ground and look straight up. Remember, your eyes can take up to 30 minutes to adjust to the darkness, so allow plenty of time for your eyes to adjust.

About the Perseids

The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Every August, the Earth passes through a cloud of the comet’s debris. This debris field consists of bits of ice and dust — most over 1,000 years old — and burns up in Earth’s atmosphere to create one of the best meteor showers of the year. The Perseids can be seen all over the sky, but the best viewing opportunities will be across the northern hemisphere. Those with sharp eyes will see that the meteors radiate from the direction of the constellation Perseus.

NASA Ustream: Observe the Perseid Meteor Shower

On Aug. 12, NASA’s Marshall Space Flight Center in Huntsville, Alabama, will host a live Ustream broadcast about the Perseid meteor shower. The event will highlight the science behind the Perseids, as well as NASA research related to meteors and comets. The broadcast will air 9 p.m. CDT Aug. 12, to 1 a.m. CDT Aug. 13 on the following Ustream channel: http://www.ustream.tv/channel/nasa-msfc

Special guests will include meteor experts Dr. Bill Cooke, Danielle Moser and Rhiannon Blaauw, all of NASA’s Micrometeoroid Office, located at Marshall. They will provide on-air commentary, as well as answer questions online, using Marshall social media accounts. Also scheduled to join the broadcast, via telephone, are experts from NASA’s Johnson Space Center, in Houston; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; the American Meteor Society; the SETI Institute in Mountain View, California; and others.

There are two methods to join the online conversation during the broadcast. NASA followers can tweet questions to “@NASA_Marshall” using the hashtag “#askNASA.” Followers may also post questions on the Marshall Facebook account, replying to the 9 p.m. Aug. 12 Perseid “Q&A” post at: https://www.facebook.com/nasamarshallcenter

Jupiter and Venus Conjunction

Posted on by .

On Tuesday, June 30, there will be a conjunction of Jupiter and Venus. A conjunction is a celestial event in which two planets or a planet and the moon or a planet and a star appear close together in the night sky. Conjunctions have no real astronomical value, but they are nice to view. While conjunctions aren’t as rare as one might think, this conjunction of Jupiter and Venus will be more impressive than most.

The casual backyard observer may have noticed that these two planets have been moving closer together for the past few weeks. On June 30, they will be so close that one will be able to hold a finger up and cover both Jupiter and Venus at the same time. In reality, the planets are hundreds of millions of miles apart. On June 30, Venus is about 46 million miles from Earth, and Jupiter is 560 million miles from Earth. Looking up at the sky, Venus appears to be much brighter than Jupiter. That is only because Venus is so much closer to Earth. Jupiter, the largest planet in our solar system, is actually over 11 times bigger than Venus, but it is dimmer when looking at the sky because of its great distance from our planet.

Typically the best conditions for stargazing involve a dark sky, so getting away from urban areas will make stars and faint objects like nebulae and galaxies more visible. The Jupiter and Venus conjunction will be easily bright enough to see from any location, even large cities. The best hours for viewing will be during evening twilight and up until 10:30 PM local time, when the planets will set behind the western horizon.cooke

Bright Sky Event Over Southeastern United States – June 29

Posted on by .
Meteor across SEComposite image showing bright event located near Rosman, North Carolina.

There was a bright event seen across several Southeast states last night at 12:29:30 AM CDT (1:29:30 EDT). Based on the data we currently have, this object was not a meteor or fireball. Tracked by 5 NASA cameras in the SE, it is moving at roughly 14,500 miles per hour, which is too slow to be a meteor. As you can see in the video, it has also broken into multiple pieces, which, combined with the slow speed, indicates a possible reentry of space debris. There are over 120 eyewitness accounts on the American Meteor Society website (www.amsmeteors.org)

The 2015 Eta Aquarid Meteor Shower

Posted on by .

Each spring as Earth passes through the debris trail from Halley’s Comet (1P/Halley), the cosmic bits burn up in our atmosphere and result in the annual Eta Aquarid meteor shower. This year the peak will occur on May 6 about 9 AM EDT with meteor rates of about 30 meteors per hour near peak. Best viewing is just before dawn on May 6. Eta Aquarids zoom around the solar system at speeds near 148,000 mph.  Unfortunately for meteor shower observing enthusiasts the moon will seriously hampered viewing of the ETAs this year. reducing the peak rate to under 20 meteors per hour.

The Eta Aquarids are pieces of debris from Halley’s Comet, which is a well-known comet that is viewable from Earth approximately every 76 years. Also known as 1P/Halley, this comet was last viewable from Earth in 1986 and won’t be visible again until the middle of 2061. The annual Eta Aquarid meteor shower gets its name because the radiant — or direction of origin — of the meteors appears to come from the constellation Aquarius.
