Ever wonder what a sunset looks like on Mars? If so, then look no further than the image above, captured by the Mars exploration rover Spirit from Gusev Crater. You can see a bluish glow - caused by high altitude dust scattering sunlight around to the night side of the planet - in the sky around and above the Sun. Such a glow can remain visible for up to 2-hours after sunset or before sunrise. Large amounts of dust in the atmosphere cause the reddish tint. Continue reading for more.
NASA astronaut Rick Mastracchio decided to take selfies to the next level earlier this year by snapping you the photo you see above during a spacewalk. For the technophiles wondering, astronauts use three Nikon D2Xs cameras to capture the images you see regularly being posted online. One thing you may not know is that the radiation damages pixels on the sensor, and sometimes, the damage is so great that the camera does not make it back to space again. Continue reading for more extreme and dangerous selfies that will make you look twice.
Whether it be lunar base to UFOs, conspiracy theorists have come up with some insane theories over the years, but this time, a shadowy humanoid-like figure has been spotted on Google Moon. YouTube user Wowforreel's video has been viewed more than two million times in less than a month. For those with Google Earth installed on their computers, type in these coordinates to view it for yourself: 27°34'26.35"N 19°36'4.75"W. Continue reading for the video and more information.
Astronaut uploaded Oleg Artemyev, currently stationed inside the International Space Station, captured the supermoon passing the Earth. This supermoon is set to accompany this year's Perseid meteor shower, one of the most anticipated events on the skywatcher's calendar. It will be up to 14% bigger and 30% brighter than other full moons during the year, but according to Dr Bill Cooke from Nasa's Meteoroid Environment Office: "Lunar glare wipes out the black-velvety backdrop required to see faint meteors, and sharply reduces counts."

The Andromeda Galaxy is the nearest major galaxy to our own Milky Way Galaxy. Together, these two galaxies dominate the Local Group of galaxies. The diffuse light from Andromeda is caused by the hundreds of billions of stars that compose it. The several distinct stars that surround Andromeda's image are actually stars in our Galaxy that are well in front of the background object. Andromeda is frequently referred to as M31 since it is the 31st object on Messier's list of diffuse sky objects. Continue reading for more.
At 02:39 UTC on Monday July 21, 1969, Armstrong opened the hatch, and at 02:51 UTC began his descent to the lunar surface. After describing the surface dust as "very fine-grained" and "almost like a powder," Armstrong stepped off Eagle's footpad and uttered his famous line, "That's one small step for [a] man, one giant leap for mankind" six and a half hours after landing. Aldrin joined him, describing the view as "Magnificent desolation." Continue reading for more.
What you're looking at above is a 773g Chinga meteorite that's been cut and polished on two sides. The top portion retains its natural light brown crust to create a dramatic contrast. This particular specimen is an iron meteorite and its total chemical composition is: 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus. Click here to view the first image in today's viral picture gallery. Continue reading for a viral video of a bank that's restoring faith to humanity.
The Drake equation is basically a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars and red dwarf stars within the Milky Way Galaxy. 11 billion of these estimated planets may be orbiting sun-like stars. Since there are about 100 billion stars in the galaxy, this implies fp*ne is roughly 0.4. The nearest planet in the habitable zone may be as little as 12 light-years away, according to the scientists. Continue reading for more.
Astronomers discovered the largest and oldest mass of water ever detected in the universe in the form of a massive, 12-billion-year-old cloud containing 140 trillion times more water than all of Earth's oceans combined. In other words, it surrounds a supermassive black hole called a quasar located 12 billion light-years from Earth. This shows that water has been prevalent in the universe for nearly its entire existence, researchers said. Continue reading for more.
The amazing image is of the Pavlof volcano erupting in the Aleutian arc and was captured by astronauts aboard the International Space Station. The ISS provides a platform to conduct scientific research. While small unmanned spacecraft can provide platforms for zero gravity and exposure to space, space stations offer a long term environment where studies can be performed potentially for decades, combined with ready access by human researchers over periods that exceed the capabilities of manned spacecraft. Continue reading for more amazing photographs captured from the ISS.
