Black hole breakthrough: New insight into mysterious jets

Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the behavior of relativistic ...

Iron-rich stars host shorter-period planets

Astronomers with the Sloan Digital Sky Survey (SDSS) have learned that the chemical composition of a star can exert unexpected influence on its planetary system—a discovery made possible by an ongoing SDSS survey of stars ...

Scientists take viewers to the center of the Milky Way

A new visualization provides an exceptional virtual trip—complete with a 360-degree view—to the center of our home galaxy, the Milky Way. This project, made using data from NASA's Chandra X-ray Observatory and other telescopes, ...

Astronomers discover a new co-moving group of stars

A team of astronomers from Germany and Hungary has detected a new group of co-moving young stars. The newly found group is located in the Upper Centaurus Lupus (UCL) section of the Scorpius–Centaurus Association. The finding ...

Planets around other stars are like peas in a pod

An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar sizes and a regular orbital spacing. This pattern, revealed ...

First PEPSI data release

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first batch of high-spectral resolution data to the scientific community. In a series of ...

Gravitational waves measure the universe

The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein's model of gravity and space-time. Modeling of these events has also provided information ...
