BU astrophysicist and collaborators reveal a new model of our heliosphere that's shaped somewhere in between a croissant and a beach ball.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.
A team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending.
This scene of stellar creation, captured by the NASA/ESA Hubble Space Telescope, sits near the outskirts of the famous Tarantula Nebula. This cloud of gas and dust, as well as the many young and massive stars surrounding it, is the perfect laboratory to study the origin of massive stars.
Despite Mercury's 400 C daytime heat, there is ice at its caps, and now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.
A team of researchers has shown a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3D image by feeding each eye with the light of a particular polarization: either horizontal or vertical. The authors managed to distinguish between the light coming from different parts of quasars -- their disks and jets -- by discerning its distinct polarizations.
Researchers at the North Carolina Museum of Natural Sciences have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new and simple method is currently being applied in a citizen science project, called Spiral Graph, that takes advantage of a person's innate ability to recognize patterns, and ultimately could provide researchers with some insight into how galaxies evolve.
Using data from the Dark Energy Survey, researchers have found and cataloged more than 300 minor planets beyond Neptune, including more than 100 new discoveries. This updated catalog of trans-Neptunian objects, and the methods used to find them, could aid in future searches for undiscovered planets in the far reaches of the solar system.
Nature magazine is publishing today a surprising study about the giant, ultra-hot planet WASP-76b in which researchers from the Instituto de Astrofísica de Canarias (IAC) have taken part.
An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has for the first time succeeded in demonstrating the ionization cooling of muons.
