The answer we had in mind for our November puzzler was fog in Argentina’s, Lake District. The exact coordinates were -40° 24′ 50.47″, -71° 22′ 59.14.” We had a number of players who came quite close — including Stuart Grice, and David P , and Michael Osborne — but no one got the exact coordinates, […]
The Marshall Meteoroid Environment office put together the plot below showing the distribution of end heights of Geminids seen with our fireball camera network. 85% of Geminids burn up 40 to 55 miles above Earth’s surface and 15% get below 40 miles altitude. Geminids penetrate deeper into the atmosphere than the Perseids because they are …
Ever wonder what it takes to pull together our web chat series? The chats usually consist of two components, live streaming and web chats. The Automated Lunar and Meteor Observatory, or ALaMO, at NASA’s Marshall Space Flight Center in Huntsville, Ala., is where the live streaming component of “Watch the Skies” begins. The ALaMO consists …
On December 5, 2012, the National Oceanic and Atmospheric Administration (NOAA) released its annual Arctic Report Card, covering late 2011 through late 2012. The report listed a number of significant events in a record-breaking and sometimes sobering year. One of the biggest stories was the record-low sea ice extent in the Arctic Ocean. Arctic sea ice […]
This morning at 6:43 AM Central Standard Time, eyewitnesses across Texas and adjacent states saw a very bright fireball streaking across the sky, moving roughly east to west. It was also recorded by a NASA meteor camera in Mayhill, New Mexico some five hundred miles to the West, which is very unusual and testifies to …
Some computer models indicate that the Earth may pass near decades old debris left behind by Comet Wirtanen in mid December, creating a new meteor shower. In the most optimistic scenario, viewers could see as many as 10-30 meteors per hour radiating from a point in the constellation Pisces in the early evenings, sometime between …
There are numerous reports of a bright fireball over northwest Alabama on Sunday, Nov. 18 at approximately 7:30 p.m. EST (6:30 p.m. CST). Southeastern cameras managed by NASA’s Meteoroid Environment Office recorded the fireball, which was brighter than the moon.

This year’s Leonids meteor shower peaks on Nov. 17 at 4:30 AM Eastern Time. If forecasters are correct, the shower should produce a mild but pretty sprinkling during the night of the 16th/morning of the 17th. The moon will be a waxing crescent setting before midnight, clearing the way for some unobstructed Leonid viewing. “We’re …
Every month, NASA Earth Observatory will offer up a puzzling satellite image here on Earth Matters. The sixth puzzler is above. Your challenge is to use the comments section below to tell us what part of the world we’re looking at, when the image was acquired, and what’s happening in the scene. How to answer. […]
The November 2012 issue of National Geographic features an article, “Sailing the Dunes,” about aerial trips over sandy deserts. The author, George Steinmetz, has flown in light aircraft in high winds—a dangerous combination. Yet the same winds that make the flying so dangerous also sculpt some of the world’s most beautiful landscapes. Several of the […]
