The Lion’s Roar: New Telescope Spots Superflare in Leo
A new telescope in Okayama, Japan observed a superflare on a star in the constellation Leo to better understand how superflares on the Sun can affect technology and life on Earth.
Rover findings indicate stratified lake on ancient Mars
A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a comprehensive look at findings from the first three-and-a-half years of NASA's Curiosity rover mission.
In a cosmic hit-and-run, icy Saturn moon may have flipped
Enceladus - a large icy, oceanic moon of Saturn - may have flipped, the possible victim of an out-of-this-world wallop.
Collapsing star gives birth to a black hole
Astronomers have watched as a massive, dying star was likely reborn as a black hole. It took the combined power of the Large Binocular Telescope (LBT), and NASA's Hubble and Spitzer space telescopes to go looking for remnants of the vanquished star, only to find that it disappeared out of sight.
Experts explain origins of topographic relief on Earth, Mars and Titan
The surfaces of Earth, Mars, and Titan, Saturn's largest moon, have all been scoured by rivers. Yet despite this similarity and the amazingly Earth-like landscapes of Titan complete with valleys, lakes, and mountains, researchers led by City College of New York geologist Benjamin Black report new evidence that the origins of the topography there and on Mars are different from on Earth.
How hard did it rain on Mars?
Heavy rain on Mars reshaped the planet's impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet's surface as we see on Earth.
