Astronomers find black hole in globular cluster

Last year when a team of astronomers led by a Michigan State University professor discovered two black holes in a collection of stars known as a globular cluster, they weren't sure if their presence was a common occurrence or a unique stroke of luck.

Astronomers establish the strength of high-inclination asteroids

A team of astronomers from the National Astronomical Observatory of Japan and the University of Hyogo used the Subaru Prime Focus Camera (Suprime-Cam) mounted on the Subaru Telescope to observe faint asteroids with highly inclined orbits. They found that a smaller fraction of tiny bodies occur among high-inclination asteroids than those near the ecliptic plane.

White dwarfs hide information on dark forces

Researchers from Europe and the USA have ruled out a multitude of possible parameters for dark photons - a type of dark matter and energy - with the help of white dwarfs. In some aspects, the shining of these dying stars gives more information on dark forces than is provided by earth-based laboratories.

A cutting-edge detector technology for astronomical observations

Semiconductors have had a nice run, but for certain applications, such as astrophysics, they are being edged out by superconductors. Ben Mazin, assistant professor of physics at UC Santa Barbara, has developed a superconducting detector array that measures the energy of individual photons.

New tool may unveil inhabitable worlds

Funding for SPIRou, a spectropolarimeter and a high-precision velocimeter optimized for both the detection of habitable Earth twins orbiting around nearby red dwarf stars and the study of the formation of Sun-like stars and their planets, was confirmed today by the Canada-France-Hawaii Telescope (CFHT) observatory.

Gravity and the robot satellite attitude problem

Using an in-orbit robot to capturing a malfunctioning satellite that is tumbling out of control is currently just a theoretical idea. However, research inspired by nature could take us a small step towards making such science fiction science fact.
