While researchers once believed that there must have been a small amount of oxygen in the Earth's atmosphere before life began, they weren't sure where this non-life oxygen came from. Now, they may have some answers..
Finding water on Mars is an important part of the hunt for life on the Red Planet. Yet actually detecting it isn't easy. Now, researchers have developed a new method for finding water on Mars.
There are an increasing number of small "CubeSat" satellites being launched into orbit. Now, though, scientists have announced that in combination with a relaxed attitude to debris mitigation, these satellites could lead to hazards for all space users.
The Wide Field Imager on the MPG/ESO 2.2-meter telescope has captured a spectacular new image of one of the most star-rich open clusters currently known.
NASA's Cassini mission continues to reveal new insights when it comes to Saturn's moon, Titan. Now, the mission has revealed that a giant, toxic cloud is hovering over the south pole of the large moon after the atmosphere there cooled dramatically.
Most of us are familiar with the "man in the moon," the shadowy face that appears in the night sky. Now, scientists have examined new data from NASA's GRAIL mission and have found that the giant basin probably wasn't created by a massive asteroid strike, as previously thought.
Astronomers have spotted two new Jupiter-sized planets orbiting a stars in a binary-star system. The findings reveal an unusual case for the extra-solar planets, most of which orbit stars that are alone.
It turns out that Earth's gravity may have experienced some changes in the past few years--and it can be blamed on melting ice. ESA's GOCE satellite has shown that ice lost from West Antarctica has caused our planet's gravity to shift slightly.
NASA's Swift satellite has officially detected the strongest, hottest and longest-lasting sequence of stellar flares ever spotted from a nearby dwarf star.
NASA's Cassini spacecraft is keeping an eye on a mysterious feature on Saturn's moon, Titan.
It turns out that some ancient, primordial stars die in an unusual way. While most stars leave behind a remnant or black hole, certain ancient, large stars may have exploded as supernovae and then burned out completely, leaving no trace behind.
