Mercury shrinking NASA confirms: 4.3 miles in 4bn years

Mercury is shrinking, its radius reduced as much as 4.3 miles over the past four billion years, scientists have confirmed, with the planet contracting as its iron core cools. The gradual reduction had been expected but unconfirmed until NASA's Messenger spacecraft beamed back photos of Mercury's surface, with previous - incomplete - footage of the closest planet to our sun showing far less shrinkage than the models predicted.

Crowdsourced Moon maps get accuracy approval

Crowdsourced Moon maps get accuracy approval

Crowdsourcing already gets products off the ground and figures out where traffic congestion is, but CosmoQuest is turning the power of group-work to map the moon. Using high-resolution images beamed back from NASA's Lunar Reconnaissance Orbiter (LRO), the public science project allows anybody to register and then sift through, flagging up craters, boulders, and other features of the rocky surface. Now, new research indicates the crowdsourced mapping can be just as accurate as when trained experts do it.

NASA WISE survey finds no Planet X beyond Pluto

NASA WISE survey finds no Planet X beyond Pluto

In 2011, a pair of physicists from the University of Louisiana at Lafayette announced that they had completed research that suggested another planet orbiting in a solar system beyond Pluto. The two professors called the theoretical planet Planet X or Tyche. The duo hoped that when NASA completed its WISE or Wide-field Infrared Survey Explorer observations the planet would be confirmed.

NASA wants funding to explore Jupiter’s moon Europa

NASA wants funding to explore Jupiter’s moon Europa

Scientists believe that one of the most likely places in the solar system to harbor life, other than Earth, is one of Jupiter's moons called Europa. Europa is covered by a thick sheet of ice over its surface, but scientists believe that under that ice are oceans of liquid. That subsurface ocean is believed to be kept liquid by tidal flexing.

Elon Musk makes SpaceX case to US Senate for fair competition

Elon Musk makes SpaceX case to US Senate for fair competition

Today Elon Musk, CEO and Chief Designer with SpaceX - and head of companies like Tesla Motors - spoke with the Committee on Appropriations Subcommittee on Defense. There he laid down a speech on the current state of affairs in space travel, NASA supply, and the way competition works within the government in these areas today. He also made clear that, with nearly 50 missions complete and a contracted total of $5 billion on the books, SpaceX is leading the way to a more efficient (and inexpensive) space-bound United States.

Hubble captures cosmic bloodbath

Hubble captures cosmic bloodbath

A collection of images have been collected and shared this week by the Hubble space telescope which depict what’s essentially a cosmic bloodbath. The team responsible for the release of the images describe the massacre of the galaxy known as ESO 137-001, one being torn asunder by a process known as ram pressure stripping. It’s a violent process.
