The Great Wall of China is not can be seen from space

One of the most popular spatial myths is that the Great Wall is the only man that can be seen from space. Well, not true. The reality is you cannot easily see the Great Wall from low Earth orbit to the naked eye. And rightly the Apollo astronauts could not see it from the moon, despite the urban legend has spread widely.

Sun's 2013 Solar Activity Peak Is Weakest in 100 Years

Though the sun is currently in the peak year of its 11-year solar weather cycle, our closest star has been rather quiet over all, scientists say.

This year's solar maximum is shaping up to be the weakest in 100 years and the next one could be even more quiescent, scientists said Thursday (July 11).

SUNNY TAIL: 3D quatrefoil

In the solar system is the tail of the solar wind particles, resembling the tail of a comet. To verify the existence of this tail, and determine its structure, scientists were able, after analyzing data collected over three years, the spacecraft NASA IBEX.

Moon Has Close Encounters with Planets, Star This Month: How to See It

If you only glance at the sky now and then, you may think it's pretty much the same every night. Regular sky watchers know better, and are aware of the constant changes the sky undergoes.

Take the moon, for example. Although most people know that the moon revolves around the Earth, they may never have noticed this movement with their own eyes. This week we get a chance to do exactly that.

Student Team Set for Zero-Gravity Fire Experiment on NASA 'Vomit Comet'

A team of university students is counting down toward the ultimate science ride, a weightless flight aboard a modified NASA jet to see just how certain fires burn in zero gravity.

The experiment, led by engineering undergraduate Sam Avery of the University of California, San Diego, is aimed at testing how biofuels burn in weightless conditions. And with a target flight date of Thursday (July 18), Avery and his crew are getting pumped.

Kepler Spacecraft Should Pin Down 'Alien Earth' Planets Despite Glitch

NASA's planet-hunting Kepler spacecraft should be able to achieve its primary mission goal regardless of whether or not it can bounce back from a recent malfunction, researchers say.

Kepler launched in March 2009 on a 3.5-year prime mission to determine how common Earth-like planets are throughout the Milky Way galaxy. 

Scientists are confused about topic of Global Warming

Scientists are confused about the predictions of the apocalypse while some experts promise to hide the carbon dioxide into the ground, the other frightening collapse of the power system topic of global warming and the related phenomenon of threats continues to occupy the minds of scientists, with no time to receive one prediction,
