Stars Forming in a Nearby Galaxy

An international team discovers a remarkable star cluster where more than a million young stars are forming in a hot, dusty cloud of molecular gases. The star cluster is buried within a supernebula in a dwarf galaxy known as NGC 5253, in the constellation Centaurus. The cluster has one billion times the luminosity of our […]

New Image of the Pillars of Creation

A new study from UCLA physicists offers a possible solution to the mystery of the origin of matter in the universe. Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very […]

Scientists Discover Organism That Hasn’t Evolved

Scientists from UCLA have discovered an organism that hasn’t evolved in more than 2 billion years. An international team of scientists has discovered the greatest absence of evolution ever reported — a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms’ […]

Gullies Suggest Past Water on Vesta

A newly published study shows evidence that transient water flowed on the surface of Vesta, in a debris-flow-like process, and left distinctive geomorphologic features. Protoplanet Vesta, visited by NASA’s Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its […]

Rivers of Glacial Meltwater Are Draining Greenland Quickly

Using satellite and field work after an extreme melt event in Greenland, new research shows that melt-prone areas on the ice sheet develop a remarkably efficient drainage system of streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. As the largest single chunk of melting snow and ice in the world, […]
