This NASA photo taken on July 16, 1969 shows the huge, 363-foot tall Apollo 11 Spacecraft, the Lunar Module S, and the Saturn space vehicle launched from Pad A, Launch Complex 39, Kennedy Space Center, at 9:32 a.m. Onboard the Apollo 11 spacecraft were astronauts Neil A. Armstrong, commander; Michael Collins, command module pilot; and Edwin E. 'Buzz' Aldrin, Jr., lunar module pilot. Apollo 11 was the United States' first lunar landing mission. While astronauts Armstrong and Aldrin descended in the Lunar Module 'Eagle' to explore the Sea of Tranquility region of the Moon, astronaut Collins remained with the Command and Service Module 'Columbia' in lunar-orbit.
Solar tsunami watchers say that the recent solar eruption could be a sign that the sun is rousing from its relative dormancy.
Plasma from the sun slammed into Earth's magnetic field Tuesday afternoon. Here's a look at what kind of northern lights show the collision will put on.
In this x-ray photo provided by NASA, the sun is shown early in the morning of Aug. 1. The dark arc near the top right edge of the image is a filament of plasma blasting off the surface - part of the coronal mass ejection. The bright region is an unassociated solar flare. When particles from the eruption reach Earth on the evening of Aug. 3-4, they may trigger a brilliant auroral display known as the Northern Lights.
One of the two cooling pumps on the International Space Station broke Saturday. The crew will have to replace the 800-pound item without help from the space shuttle.
People carry their belongings after heavy flooding destroyed their homes in Nowshera, Pakistan, on Monday. The government has deployed thousands of soldiers and civilian rescue workers to save an estimated 28,000 people trapped by the floodwaters, and to distribute food and collect the bodies of the victims.
This photo, captured by the NASA Hubble Space Telescope's Advanced Camera for Surveys, is Hubble's latest view of an expanding halo of light around the distant star V838 Monocerotis, or V Mon, caused by an unusual stellar outburst that occurred back in January 2002. A burst of light from the bizarre star is spreading into space and reflecting off of surrounding circumstellar dust. As different parts are sequentially illuminated, the appearance of the dust changes. This effect is referred to as a "light echo".
Life on Mars: A new study has identified a spot that could be a good place to search for fossilized remains of life on Mars.
The newfound failed star, known as a brown dwarf, has been dubbed PZ Tel B. It is separated from its sun-like companion star, PZ Tel A, by a distance similar to that between Uranus and the sun in our solar system.
