News: Watch NASA's Tracer Rockets Light Up the Sky with Cloud Trails
This morning, NASA launched the five suborbital sounding rockets from Virginia as part of ATREX (Anomalous Transport Rocket Experiment). Each rocket was launched 80 seconds apart and released chemical tracers that created "milky, white clouds at the edge of space." Now, I've seen plenty of bullet tracers in my life, but these are far more poetic. Take a look at the time-lapse video and see for yourself. Why shoot these tracer rockets? To help scientists "better understand the process responsi...
Important Astronomers: Isaac Newton
In my opinion, Isaac Newton is definitely the number two astronomer, right below Galileo Galilei. His discoveries were very important to uncovering the secrets of space, and he deserves to be remembered.

Important Astronomers: Galileo Galilei
I'm starting a series on the top astronomers, with probably about eleven astronomers that I will be covering overall. So, let's start out from the top, with the top most important astronomer. In my opinion, Galileo Galilei is the top astronomer.
News: Photos of Mercury and the crescent Moon
Tonight, I saw Mercury for the first time. Mercury is a hard planet to see, even though it is quite bright, because it's orbit is so close to the sun. The angle Mercury makes with the Earth and the Sun is never more than about 25 degrees and most of the time it is much less. As a result, you can't ever see Mercury during the night but at a couple of times in it's orbit you can see it at either dawn or dusk. Right now, Mercury is close to it's greatest eastern elongation and can be seen low in...

Dancing Droplets: Water Orbits Statically Charged Knitting Needles in Space
His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.
News: Two Bright Nebulae in Orion's Sword
My attempt at real astrophotography. The two bright nebula are M 42 and M 43 located in Orion's Sword. I took about 20 images at ISO 800 and 1.6 second exposures using a 300 mm lens and stacked them in Photoshop after repositioning them because of the movement of the sky. This is cropped in just a tiny bit.
News: Astronomer Creates "Meteorito" Wine That's Out of This World—Literally
What happens when you combine a passion for astronomy and a love of wine? Cabernet that's out of this world. Literally. It's called Meteorito, and has a berry, nutty flavor with just a hint of iron and nickel. The wine was made by oenophile and amateur astronomer Ian Hutcheon, who runs his own vineyard and established an observatory in Chile called Centro Astronomica Tagua Tagua.

News: Solar Flare Gives Earth Biggest Radiation Storm in 7 Years; Auroras Likely
NASA reports that the sun erupted late last night with a large solar flare—an M8.7 class flare. The classification is calculated according to the peak flux of 100 to 800 picometer x-rays near Earth measured from the GEOS weather satellite. There are 5 letter classifications for solar flares, each with a linear 1-9 number scale of severity. M is the fourth most powerful class, with X leading the way. But last night's earth-directed coronal mass ejection (CME), captured by the Solar Dynamics Ob...

News: Galactic Search Finds Exoplanets Are More Common Than Stars
Recent research published in an issue of Nature suggests that there are actually more planets in our universe than stars. Using the Milky Way as the focus, the researchers found that each star has an average of about 1.6 planets in orbit around it, which suggests that extrasolar planets (exoplanets) outnumber stars, bringing new hope for the search of extraterrestrial life.

News: Quadrantid Meteors and Startrails
I took about 700 pictures over 7 hours late Tuesday night and early Wednesday morning of the quandrantid meteor shower. I combined the clearest 300 of them to make the star trails, and then went and found individual pictures with the brightest meteors and overlayed them on top. I also found three planes flying overhead and overlayed those as well. The gaps in those plane streaks heading towards the horizon show how long my camera was taking between frames.
News: Photo Highlights from the Quadrantid Meteor Shower
If you slept in during the peak of the Quadrantid meteor shower this morning, don't fret, because plenty of early risers did manage to wake up—with their cameras. Even if you did wake up and managed to withstand the cold morning air, you might not have seen anything. Cloud cover could have made it impossible, as well as bright city lights. But some stargazers made it their mission to photograph the Quadrantids, and lucky for you, they did.
News: NASA Kicks Off 2012 with Ambitious New Moon Mission
More than 100 missions targeted at Earth's moon have been launched by space explorers since the late-1950s. NASA landed a total of 12 men on the lunar surface, collecting more than 800 pounds of moon rocks and lunar soil samples. But still, the moon remains a mystery, especially its formation. NASA's new mission aims to find out exactly how the moon came to be with the Gravity Recovery and Interior Laboratory, or GRAIL, part of NASA's Discovery Program.
News: 2012 Doomsday Predictions Debunked by NASA
Will the world end this coming December? If you believe all of the Mayan calendar hype, maybe. But whether you believe that doomsday is coming in 2012 or not, you can rest assured it won't be from a planetary collision. At least, according to NASA.

There are a lot of events going on this week! As I mentioned last week, there will be new features from now on. Check them out in the info section below!
How To: Observe the Quadrantid Meteor Shower
Note: This shower is only visible in the Northern Hemisphere. The Quadrantid meteor shower is one of my personal favorites, mainly because of the amount of meteors it produces. You can sight more than 100 meteors per hour- that's more than 1 meter per minute. Even though that doesn't sound like much, it will make your observing experience much more exciting. The peak is short, typically lasting no more than an hour or so. It is more easily observed on the fourth, with its peak at 1:00 AM EST.
News: Timelapse Footage of a Moonrise
This is a really quick video I took of a moonrise last year. It has been sped up by a factor of 8 and was taken using a 2600 mm equivalent lens (75 times zoom for a 35 mm lens). The mountain it is rising over is about 40 miles away.
