Latest Stellar kinematics Stories
Scientists using the NASA Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years away from Earth.
Astronomers using NASA's Hubble Space Telescope to peer deep into the vast stellar halo that envelopes our galaxy have uncovered tantalizing evidence for the possible existence of a shell of stars that are a relic of cannibalism by our Milky Way.
Black holes are very efficient eating machines… They can double their mass in less than a billion years. That may seem long by human standards, but over the history of the Galaxy it's pretty fast.
The massive black hole at the center of our Milky Way Galaxy is destined to be invaded by a gas cloud, creating a violent encounter, according to astronomers.
Not all stars are loners. In our home galaxy, the Milky Way, about half of all stars have a companion and travel through space in a binary system.
A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep.
NASA's Hubble Space Telescope has provided astronomers with the best observational evidence to date that globular clusters sort out stars according to their mass, governed by a gravitational billiard ball game between stars.
An international team of astronomers today announced the first results from the Radial Velocity Experiment, an ambitious all-sky spectroscopic survey aimed at measuring the speed, temperature, surface gravity and composition of up to a million stars passing near the sun.
Ancient black hole speeds through Sun's galactic neighborhood, devouring a nearby companion starHubble Space Telescope -- Data from the Space Telescope Science Institute's Digitized Sky Survey has played an important supporting role in helping radio and X-ray astronomers discover an ancient black hole speeding through the Sun's galactic neighborhood.
