How can the temperature of the Sun's atmosphere be as high as 1 million degrees Celsius when its surface temperature is only around 6000 degrees? By simulating the evolution of part of the Sun's interior and exterior, researchers have identified the mechanisms that provide sufficient energy to heat the solar atmosphere.
The researchers examined samples from six meteorites of volcanic rock that originated on Mars. The meteorites contain gases in the same proportion and with the same isotopic composition as the Martian atmosphere. All six samples also contained methane, which was measured by crushing the rocks and running the emerging gas through a mass spectrometer.
Astronomers have succeeded in recording the first image with the most sensitive millimetre radio telescope in the northern hemisphere: The installation known as NOEMA provided a spectacular image of a previously unknown region of massive star formation in the Medusa Merger - a brightly shining pair of colliding of galaxies.
The high seas of Mars may never have existed. According to a new study that looks at two opposite climate scenarios of early Mars, a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the planet today.
To sort out the biological intricacies of Earth-like planets, astronomers have developed computer models that examine how ultraviolet radiation from other planets? nearby suns may affect those worlds, according to new research.
The German Aerospace Center is scheduled to launch its Eu:CROPIS research satellite into orbit in early 2017. Its purpose is to test a biological life-support system for future human space missions. The satellite's payload includes an ion analyzer. This compact device will automatically monitor all of the system's internal processes.
The search for the three-legged lander is complex because even when fully illuminated by the Sun, Philae will be just a few pixels across in images acquired by the Rosetta orbiter's Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS).
The Dawn orbiter initially traced the path of the equator before crossing the north and south poles of Ceres. Researchers have used the images acquired thus far with the Framing Camera on board the spacecraft and the first three-dimensional terrain models created from them to produce a virtual scenic flight over icy Ceres.
Researchers have used satellite data to detect deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, the glasses just might provide a delicate window into the possibility of past life on the Red Planet.
If you lived on one of Pluto's moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA's Hubble Space Telescope shows that two of Pluto's moons, Nix and Hydra, wobble unpredictably.
