How To: There's a Total Lunar Eclipse Monday Night—Here's How to Watch the "Blood Moon" Rising

Get ready to look up in the night sky very soon, because you're in for a real treat. There will be a total lunar eclipse on the night of Monday, April 14th, and folks living in the United States, Canada, and parts of Central and South America will be able to see the moon turn a dark blood-red shade for a little over an hour. This will be the first in a series of four total eclipses that are to happen over the next two years. What Is a Blood Moon?

How To: Watch Asteroid 2012 DA14 Zoom Past Earth Today

Earlier today, a meteorite flew over the Chelyabinsk region of Russia, triggering a shock wave that injured hundreds of people and caused damage to buildings and vehicles in the area. Witnesses describe seeing a bright ball of light streak through the sky followed by a loud boom as the 10-ton meteorite entered the Earth's atmosphere and exploded.

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...

How To: Chat with NASA Astronauts Live from the International Space Station on February 22nd

Inhabiting the microgravity environment on the cusp of the world's atmosphere has to be filled with some of the most unique experiences in the world. Astronauts eat, sleep, and work just as we do, except that their lives are filled with the added dangers of extreme temperatures and possible life-threatening malfunctions, all while being 240 miles up in the sky. Well, now's your chance to ask a handful of astronauts anything you ever wanted to know about life on the International Space Station.

How To: Help NASA Write Code to Fix the International Space Station and You Could Win $10,000!

The International Space Station is a habitable man-made satellite currently in orbit around the Earth. Launched in 1998, the ISS is used mainly as a microgravity and space environment research laboratory where astronauts perform experiments in large variety of fields, including biology and physics. In order to be hospitable for crew members and scientists, the ISS needs energy. To do this, the station uses its solar panels to capture rays of sun and power the station up. In order to garner th...

How To: Watch Tonight's Peaking Geminid Meteor Shower—About 100 Shooting Stars Per Hour!

The Geminid meteor shower happens every December and has been observed for over 500 years. It's is also known as Winter's Fireworks because when viewed from the right location, there are enough meteors to light up the whole night sky, and some of them can even be different colors. The shower appears to come from the Gemini constellation, but is actually caused by Earth passing through the tail of dust and debris left behind by the comet 3200 Phaethon.

How To: Know Exactly When You Can Spot the International Space Station at Home with NASA Text Alerts

The International Space Station is one of the brightest objects in the night sky when it can be seen. If you know when and where to look, you can even see it from your house. It looks more or less like a really fast-moving plane—so fast, actually, that it's only visible from a specific place for a few minutes at a time. But now you don't have to do a ton of mathematical equations or rely solely on luck to spot the ISS at night. NASA just launched a program called Spot the Station that sends y...

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 ...

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...
