Supermoon will be big, bright, and full on June 23

Supermoons can tend to get doomsdayers revved up.

Besides being a remarkable sight to behold, the massive moon also comes with the mythical stigma of causing a handful of natural disasters, including earthquakes and tsunamis, floods, typhoons, and cyclones.

And, this year's supermoon is quickly upon us. It will be shining its light next weekend on June 23. On that day, the moon will appear bigger and brighter, and be closer to Earth than it's been all year -- a total of 221,824 miles away, which is roughly 30,000 miles closer than when it's at … Read more

Watch astronaut Chris Hadfield's zero-gravity workout

If you think your workout is reaching a plateau, don't complain to the men and women in space. They have to constantly work out to stave off the loss of muscle tissue.

People living in zero gravity can lose up to 5 percent muscle mass a week. Yikes! That's why working out isn't just something astronauts do because they had a double cheeseburger with onion rings for lunch. Curious about what a space workout looks like? … Read more

Gravity powers new lamp for developing countries

It's easy to take our electric lights for granted. Many people in developing counties don't have the luxury of electric grids and have to rely on kerosene lamps to brighten the night. Kerosene costs money and breathing the fumes is dangerous. A new light powered by gravity could be a superior solution to lighting needs.

GravityLight doesn't need to be recharged through solar cells. It doesn't use batteries at all. It's powered by the same force that keeps our feet on the ground. A weight attached to the light takes 3 seconds to lift up, but provides 30 minutes of light as it descends. … Read more

Space: a new angry frontier

Angry Birds Space feels at once familiar and fresh. Unlike the previous sequels, which were pretty much the same game in different settings, Angry Birds Space puts a new spin on things with gravity-oriented physics, new obstacles to navigate, and bonus levels that add to the fun.

The gravitational mechanic in many of the levels adds a completely new element to how you approach each level. A flung bird might curve around a moon in one direction and then curve the other way once it passes into the next moon's orbit. It can also get caught in a gravity … Read more

Black hole clocks fastest wind ever recorded by NASA

Although black holes are invisible, they can be found by watching their effect on nearby gas and stars. For stellar-mass black hole IGR J17091, this is exactly what is happening. Its gravity is pulling gas away from a companion star and this gas has formed into a disk around the black hole, which is driving off wind.

However, there's something special about IGR J17091--the wind it's creating is the fastest wind ever discovered blowing off a disk surrounding a stellar-mass black hole.

In most other ways IGR J17091 is pretty much a ho-hum black hole: it's located … Read more

T-Mobile announces Samsung Gravity TXT

T-Mobile announced a new messaging phone today called the Samsung Gravity TXT. It looks like a successor to the Samsung Gravity 3, with the same slider-QWERTY form factor. Features are fairly basic, and include a 2-megapixel camera, GPS, 3G, support for Microsoft ActiveSync in e-mail, and Bluetooth.

Samsung Gravity Smart review: The Gravity grows up

The words "Samsung Gravity phone" immediately conjure images of tall feature phones with funky-shaped keys, QWERTY sliders, and pronounced accents in flame or neon colors. Take the Samsung Gravity Smart, then, as the mature member of this fun-loving family for T-Mobile. It's brainier, running Android 2.2 Froyo instead of Samsung's own feature phone OS. It also veers away from electric blue and blow-your-eyes lime with color options that tend toward the more subdued--a lush berry is this handset's most pulse-quickening hue (don't worry, even the lunar gray color still has its bright elements.)… Read more
