Astronomers detect seismic ripples in ancient galactic disk

A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy ...

Young open cluster Messier 39 investigated in detail

Italian astronomers have performed high-resolution spectroscopic observations of a young open cluster known as Messier 39. Results of the observational campaign, presented in a paper published Dec. 14 on the pre-print server ...

NGC 2264: Telescopes illuminate 'Christmas tree cluster'

This new image of NGC 2264, also known as the "Christmas Tree Cluster," shows the shape of a cosmic tree with the glow of stellar lights. NGC 2264 is, in fact, a cluster of young stars—with ages between about one and five ...

A 14-inch spacecraft delivers new details about 'hot Jupiters'

A spacecraft the size of a cereal box has collected precise measurements of the atmospheres of large and puffy planets called "hot Jupiters." The findings, led by a team from the University of Colorado Boulder, could help ...

Did the last great galactic merger create the Milky Way's bar?

The Milky Way is a spiral galaxy. More specifically, it is a barred spiral galaxy, meaning that within its central region, there is a bar shape off of which the spirals emanate. About two-thirds of spiral galaxies are barred ...

Image: Hubble captures a cluster in the Large Magellanic Cloud

This striking Hubble Space Telescope image shows the densely packed globular cluster known as NGC 2210, which is situated in the Large Magellanic Cloud (LMC). The LMC lies about 157,000 light-years from Earth and is a so-called ...

Astronomers investigate the Southern Beehive cluster

An international team of astronomers has performed the first asteroseismic study of the young open cluster NGC 2516, better known as the Southern Beehive. Results of the study, published Nov. 28 on the pre-print server arXiv, ...
