Scientists now know exactly where to look for fossils on Mars

  Scientists now know exactly where to look for fossils on Mars Nobody knows for sure whether or not life had ever taken root on Mars. The study, which was led by a researcher from the University of Edinburgh, was published in the Journal of Geophysical Research. It focuses on some very specific places on the red planet where fossils are likely to exist, namely inside rocks near long-dead lakes, using knowledge from gained from fossil hunting here on Earth to give Mars researchers their best shot at finding evidence of Martian life.

Deep beneath the Earth’s surface, there’s a gigantic cache of diamonds, according to new research. While it’s unlikely that we’ll ever be able to obtain these diamonds, knowing that they’re there helps us learn more about our own planet and what it’s made of.

To discover what lies beneath the surface, scientists can’t simply look with their eyes. Instead, they use sound waves and listen. Unlike light, sound can travel through solid rock, and by listening closely scientists can learn a great deal about what the inside of the Earth is like.

Typically, these sounds come from earthquakes or volcanic explosions, and by studying the resulting seismic waves scientists can determine what materials lie underground. One group of scientists was studying a strange anomaly that occurs when these seismic waves pass through underground structures called cratonic roots. These structures are ancient, highly dense rock formations shaped like inverted mountains that lie hundreds of miles beneath most tectonic plates.

Astronomers spot a trio of Earth-sized planets orbiting a distant star

  Astronomers spot a trio of Earth-sized planets orbiting a distant star Humanity is going to have to leave Earth eventually. We've already messed up our planet pretty badly, and even if we don't push the Earth completely over the edge ourselves there's the simple fact that no planet lasts forever. The planets, which were discovered around a star called K2-239, are incredibly close to Earth in overall size, with radii measuring between 1.0 and 1.1 times that of our own planet. The research was published in the Monthly Notices of the Royal Astronomical Society.

Because these rock formations are so dense, sound waves move much faster through these cratonic roots than through most other rock. But for some reason, many of the seismic waves measured over the last few decades move even faster than predicted. A group of scientists, led by MIT scientist Ulrich Faul, suspected that some material inside the cratonic roots was speeding up these waves.

To figure out what exactly these roots were made of, the researchers created a series of computer simulations using hypothetical rocks made of different materials. Of all the different simulations they tested, the only one that agreed with the data was a simulation where the cratonic roots were made of about one to two percent diamond, in addition to ordinary rock.

NASA finds ‘spiders’ on Mars, but not the kind you’re thinking

  NASA finds ‘spiders’ on Mars, but not the kind you’re thinking The search for evidence of past life on Mars is a long, complicated endeavor that NASA has devoted an incredible amount of time and money to. That investment may pay off one day soon, but in the meantime we’ll have to settle for all the cool non-living sights Mars has to offer, like these “spiders” captured by NASA’s Mars Reconnaissance Orbiter.Load Error

This discovery is a big deal because cratonic roots make up a significant fraction of our planet’s crust. If even two percent of these structures are made of diamond, that equals quadrillions of tons of the mineral buried under the surface. Unfortunately, cratonic roots are located around a hundred miles underground, so mining expeditions seem unlikely.

"This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it's relatively common," said Faul. "We can't get at them, but still, there is much more diamond there than we have ever thought before."

NASA chief excited about prospects for exploiting water on the moon .
<p>NASA Administrator Jim Bridenstine has a vision for renewed and "sustainable" human exploration of the moon, and he cites the existence of water on the lunar surface as a key to chances for success.</p>"We know that there's hundreds of billions of tons of water ice on the surface of the moon," Bridenstine said in a Reuters TV interview in Washington on Tuesday, a day after NASA unveiled its analysis of data collected from lunar orbit by a spacecraft from India.
