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.
I came across these beautiful wallpapers while browsing +Guy Kawasaki's Google+ stream. Basically, someone combined Calvin and Hobbes with the OS X Lion desktop wallpaper to make some truly fun artwork. Click on the link for access to the full-resolution wallpapers.
With the ever-evolving technology that imbues photography, we are never short of fantastic awe-inspiring shots. Digital cameras can capture things that the naked eye only wishes it could see, like streaking lights, rapid movements, and faraway objects, and it's fairly easy to capture these things if you know the basics.
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.
Again, there are tons of events this week, and as usual, most of them are caused by Jupiter's moons. But there is some happenings with Venus, too, so don't miss out.
Where would you end up if you dug a tunnel in your backyard straight through the Earth? If you live in the United States, you'd probably think that you'd end up somewhere in China. But despite what the hypothetical China Syndrome may have you believe, China is not the other side of the world.
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.
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)!
So, I got this email today from Groupon claiming today is Earth's 400 birthday. Groupon is known for their humor, but how (and why) did they pick today as Earth's 400th birthday?
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...
Hello! I invite all the readers, interested in space, to discover the origin of the names of the planets in our galaxy. Just simply follow my words,... Step 1: Planets and Stars
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 ...
Astronomy World will be posting a weekly blog post that informs fellow observers upcoming interesting events in the sky. These will include:
Since the Geminid Meteor shower is intensifying more every year, grab your binoculars and lay down in a field to enjoy the show! If you are going to observe one day, do it on the peak: December 14th.
There isn't much going on this week, unless you like to observe the moons of Jupiter! January 27: Io transit
Remember—winter is the perfect time to observe! There are a lot of events going on this week, so pull out that observing chair. Here they are:
Water covers approximately 70 percent of Earth's surface and the human body contains up to 78 percent water, depending on body size. Yet, water seems to be taken for granted here on Earth. But if you travel to an orbital altitude of about 250 miles, water starts looking pretty interesting. Especially to astronaut Don Pettit on-board the International Space Station.
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 ...
NASA announced yesterday that their Kepler mission has discovered the first Earth-sized planets orbiting a sun-like star outside of our solar system. Could this mean aliens? Unfortunately, no.
Are you a big astronomy enthusiast? Do you have some amazing astrophotography pictures you'd like to share? If so, become a contributor over here at Astronomy World! We are looking for new moderators, along with contributors, to post pictures and videos, write tutorials and astronomy-related news articles, and even share updates on how your observing went!
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:
As a kid, I was always interested in what was beyond our world. I remember lying down on the top of my dad's car and watching the stars for hour, gleefully excited whenever a shooting star streaked across the night sky.
When Cerek mentioned astronomy-inspired artwork in his Astronomy World introduction post, I immediately thought of Russell Crotty. Crotty is a California artist who creates beautiful sculptures and drawings inspired by astronomy, landscape, and surfing.
So, I managed to take some pics last night of the supermoon. I was dropping someone off at LAX right around perigee, so all of the images I took off the side of the road were horrible, since there were tall buildings everywhere and nothing but street and parking lot lights blocking my shots.
There's nothing more inherently awesome than looking up into the stars and wondering WTF is really out there. Outer space is one of those rare items that a Google search cannot provide all of the answers for.
Taken at the top of Haleakala in Maui.
I think most of these are iPad apps, which I don't have, but I'd love to see some reviews of some of these apps to find out whether they're worth downloading or not.
This week's AON has lots of conjunctions—be sure to observe them! Here it is: The Garradd comet is still in the sky! Here's how to observe it!
The comet Garradd is almost at its peak now, plus there's plenty more events going on this week, so be sure to observe!
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...
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.
This week's AON may be a little short, but the ones to come will be packed full with information. I am really hoping for the skies to clear so I can observe soon!
Seeing an aurora in person is one of the most amazing spectacles you could witness in the skies above. But what about the skies below?
This week's AON is pretty short, but there are also lots of clouds because it is winter. However, that just makes the few days of open sky way more valuable!
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...
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!
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.
Went outside tonight to see a 22 degree halo around the moon. Took a long exposure shot of it to bring out some of the color. Jupiter is to the right and Orion is to the left.
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.
