SpaceX's Dragon cargo ship splashes down in Pacific

SpaceX's Dragon cargo ship splashes down in Pacific

This is a good thing! Nobody was injured in the splash because this drop was an unmanned mission to provide goods from the International Space Station back to Earth. Additionally, miscellaneous tests were conducted on Dragon, mainly involving cell reaction to spatial conditions.

Is Earthly life premature from a cosmic perspective?

Is Earthly life premature from a cosmic perspective?

Where are all the aliens at? Apparently, there's a good chance they're in the future.

The further humans travel into the future, the better the odds are for life forming elsewhere. Researchers believe that the best chance for life is near a star with a long lifespan, such as a red dwarf star. Scientists will refocus the search for other beings around red dwarves.

Mars gullies likely not formed by liquid water

Mars gullies likely not formed by liquid water

NASA's Mars Reconnaissance Orbiter has returned data back to NASA suggesting that the current gullies on Mars were not formed due to liquid flowing water. Gullies look like former streams with debris and no water; Earth has gullies too that are replete with H2O, but Mars' physical features appear to have been created differently than Earth's landforms.

Scientists looking for invisible dark matter can't find any

Scientists looking for invisible dark matter can't find any

Dark matter comprises 80% of the universe. Unfortunately, dark matter comprises 0% in a defunct gold mine in Lead, South Dakota. For three years and ten million dollars, scientists searched a mile underground with liquid xenon which would glow when certain dark matter particles reacted with the xenon. Alas, that didn't happen, but those involved in the project are eager to try again in a different location.

Two super-Earth-sized planets discovered orbiting a nearby star

Two super-Earth-sized planets discovered orbiting a nearby star

NASA's Kepler has found two more planets on its K2 extended mission. Both of these planets reside near a star 150 light years away. The star, known as HD 3167, is approximately the size of the sun, and has two planets: the smaller planet is 60% larger than Earth, and the larger is 200% larger than Earth. Kepler has found over 100 undiscovered planets.
