New Horizons Reveals Two Distinct Faces of Pluto

The New Horizons Spacecraft has captured new color images of mysterious spots on Pluto. The new color images from NASA’s New Horizons spacecraft show two very different faces of the mysterious dwarf planet, one with a series of intriguing spots along the equator that are evenly spaced. Each of the spots is about 300 miles […]

Active Pits on Comet 67P

A newly published study reveals that 18 quasi-circular pits in the northern hemisphere of comet 67P/Churyumov–Gerasimenko’s are responsible for its halo of dust and gas. A number of the dust jets emerging from Rosetta’s comet can be traced back to active pits that were likely formed by a sudden collapse of the surface. These ‘sinkholes’ […]

Big Bang to Big Rip Illustration

A fundamentally new mathematical formulation from Vanderbilt University has some significant implications for the ultimate fate of the universe. The universe can be a very sticky place, but just how sticky is a matter of debate. That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the laws […]

Astronomers Discover Dust-Forming Molecule Si-C-Si

After decades of speculation and searching, astronomers have discovered the important dust-forming molecule Si-C-Si (disilicon carbide) in space. The space between stars is not empty — it contains a vast reservoir of diffuse material with about 5-10% of the total mass of our Milky Way galaxy. Most of the material is gas, but about 1% […]

Cassini Views Spirals in the D Ring

In this image NASA’s Cassini Spacecraft reveals the spiral structures in Saturn’s D ring. Although the D ring of Saturn is so thin that it’s barely noticeable compared to the rest of the ring system, it still displays structures seen in other Saturnian rings. Here the spiral structures in the D ring are on display. […]
