Believe it or not, astronomers have found an enormous void in space that measures nearly a billion light-years across. This void is empty of both normal matter - such as galaxies and stars - and the mysterious "dark matter" that cannot be seen directly with telescopes. One of the researchers said: "If you were to travel at the speed of light, it would take you several years to get to the nearest stars in our own Milky Way galaxy; but if you were to go to this hole and enter one side, you'd have to travel for a billion years before you would get to the other side."

The International Space Station maintains an orbit with an altitude of between 330 km (205 mi) and 435 km (270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.50 orbits per day. The ISS crew provides opportunities for students on Earth by running student-developed experiments, making educational demonstrations, allowing for student participation in classroom versions of ISS experiments, and directly engaging students using radio, videolink and email. When the astronauts aren't working, they can be found photographing various things, such as these amazing volcanic eruptions.

According to researcher Scott Waring, "An artificial light source was seen this week in this NASA photo which shows light shining upward from...the ground. This could indicate there there is intelligent life below the ground and uses light as we do. This is not a glare from the sun, nor is it an artifact of the photo process."

Scientists have discovered a massive underground ocean of water on Saturn's moon, Enceladus. The Cassini spacecraft conducted gravity measurements that show the internal structure of the moon, including the ocean of water underneath the moon's icy crust. This makes Enceladus a potential home for extraterrestrial life within our solar system. Continue reading for a video and more information.

Could this be a sign? The image above of the M87 galaxy shows a black hole-powered stream of electrons barreling into space, traveling near the speed of light. What this indicates is that there may be a super-massive black hole at the center of this galaxy, with this particular example believed to have "swallowed up" matter equal to 2-billion of our suns.

Jupiter's bright yellow Io is currently the strangest moon in our Solar System right no, and this is how it would appear in the "true colors" perceptible to the average human eye - taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes. The intense tidal gravity of Jupiter stretches Io and damps wobbles caused by Jupiter's other Galilean moons. Continue reading for more.

The Sun does not have enough mass to explode as a supernova. Instead it will exit the main sequence in approximately 5.4 billion years and start to turn into a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of the solar system's inner planets, possibly including Earth.

Did you know that duct tape helped save the Apollo 13 crew because it put together the pieces of the land Rover so they could get back to their space craft? The CO2 filtering system for the Lunar Module was designed for only 2 people for only 3 days, and the filter quickly became saturated. NASA engineers on the ground figured out how to use the spare CO2 filters from the command module, which were of a different size and configuration from the LM filter, piecing together space suit hoses, cardboard from a supply box, plastic bags and holding it all together with lots of duct tape. They talked the Apollo 13 astronauts through the steps required to make and install the make-shift filter, now referred to as the "mailbox" and it worked. Without this solution, the Apollo 13 crew would have died from CO2 poisoning. Also, duct tape was used on Apollo 17's lunar rover...to hold together a makeshift fender after they discovered that gritty lunar dust thrown up by the rover's tires was clogging the instruments and space suit filters.

You read that right, researchers have discovered a gigantic planet that's ten times larger than Earthorbiting the sun at the edge of our solar system. It's called 2012 VP113 and along with up to 900 other objects, are orbiting in a similar formation. What this means is that a larger planet, called a Super Earth because of its size, may be creating a shepherding effect pulling these objects around with it.

A donut-shaped planet with zero tilt would have an extremely cold "hubward" side - that is, the side closest to the rotational axis - because this region would never get any light. On the other hand, one with an earth-like tilt of approximately 23 degrees would have amazing colors during its spring dawns and autumn twilights on the hubward side, due to the sun rising past the atmosphere of the other side of the planet.
