News: Top 5 Alien Worlds That Could Host Alien Life!

Video: . Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien," a "space alien"). These as yet hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might exist extraterrestrially has also been proposed.

This week's AON might be a little short, but finally, the Garradd comet's peak has come! I picked the Garradd comet to follow because it's a bright and easy-to-follow comet. Be sure to observe it! If you need help finding it, you can find more information here.

News: Some Small Pics of the Partial Solar Eclipse

I managed to take a few snapshots of the solar eclipse in the Malibu area, where it was just a partial. Just wanted to share a few. I've still got the same setup as when I took my supermoon pics, but hopefully one day I'll be able to get something bigger than my 105mm capabilities, something like Cory's awesome solar telescope (see his time-lapse of the annular)!

How To: SETI Needs Your Help Renaming Pluto's Newly Found P4 and P5 Moons

In 2006, everything that revolved around my world shattered into tiny pieces as I learned that scientists had decided to rescind Pluto's planetary status. Given the ol' Jeff Probst treatment, Pluto was officially voted off our solar system in the blink of an eye, leaving us with only eight planets and a whole load of useless textbooks. The primary reason that Pluto was demoted down to a "dwarf planet" was due to Pluto's largest moon, Charon, being about half the size of Pluto; all the other p...

News: Jupiter and Venus Rising Before the Sun

Right now, Jupiter and Venus are rising in the early morning hours just before dawn. I went outside on the morning of the 4th of July and saw Jupiter and Venus right next to each other with the Pleiades (The Seven Sisters) just above them and knew that the next morning I was going to have to get up early and set up my tripod to try and capture what I saw. I used my Panasonic GH2 with the stock zoom lens set to about 40 to 50 mm equivalent and with the aperture open to about f/5. I set my ISO ...

How To: Watch NASA's Curiosity Rover Land on the Surface of Mars Tonight (Live Online)

NASA will be attempting to land the Curiosity rover on the surface of Mars tonight, and you can watch it live. Curiosity (the Mars Science Laboratory) was launched almost a year ago on November 26, 2011, and will be finishing its 354 million mile journey to the red planet tonight (Sunday, August 5th) at around 8:30pm PST. The craft will be deploying a supersonic parachute to slow itself, as it will be traveling at upwards of 1,000 mph. The show's not over though, as the first images from the ...

News: Astronomical Observing News (2/21 to 2/27)

There's not much going on this week in the skies above, but there are a lot of conjunctions to take a peek at! And of course, there's the comet Garradd that's still showing its tail to us down here on Earth, so make sure to catch it before it's gone. The rest that's going on this week:

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...

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.

How To: Find and Observe the Garradd Comet

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...

News: Astronomical Observing News (3/28 to 4/3)

Grab your binoculars and telescopes, because there's a lot going on in the night skies this week. The usually dim Little Dipper will appear brighter as it moves to the right of Polaris, creating a cool effect with the Big Dipper. There's also a first-quarter moon and a really good view of Saturn. If you know of something else, share with us in the comments below!

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: Astronomical Observing News (3/7 to 3/13)

AON is moving to Wednesdays! There are lots of things going on this week in the skies above, so be sure to observe. As usual, there's a lot to see around Jupiter, with its moons eclipsing and transiting. Also, a star from the Virgo constellation will be in conjunction with our Moon.
