Decades of Research Identify Source of Galaxy-Sized Stream of Gas

University of Wisconsin-Madison

A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.

Brain Size of Human Ancestors Evolved Gradually Over 3 Million Years

University of Chicago Medical Center

Modern humans have brains that are more than three times larger than our closest living relatives, chimpanzees and bonobos. Scientists don't agree on when and how this dramatic increase took place, but new analysis of 94 hominin fossils shows that average brain size increased gradually and consistently over the past three million years.
