Soft shells and strange star clusters

The beautiful, petal-like shells of galaxy PGC 6240 are captured here in intricate detail by the NASA/ESA Hubble Space Telescope, set against a sky full of distant background galaxies. This cosmic bloom is of great interest ...

New class of old star cluster discovered

(Phys.org) —Star clusters with properties not seen before have been discovered by an international team of astrophysicists, led by Swinburne University of Technology's Professor Duncan Forbes.

Stars' orbital dance reveals a generation gap

UBC astronomers have used NASA's Hubble Space Telescope to track the orbital motion of 33,000 stars in one of the Galaxy's oldest globular clusters, offering new insights into the formation of the Milky Way.

Inseparable galactic twins

(Phys.org) —Looking towards the constellation of Triangulum (The Triangle), in the northern sky, lies the galaxy pair MRK 1034. The two very similar galaxies, named PGC 9074 and PGC 9071, are close enough to one another ...

Low-sodium diet key to a stellar old age, astronomers find

(Phys.org) —Astronomers expect that stars like the Sun will blow off much of their atmospheres into space near the ends of their lives. But new observations of a huge star cluster made using ESO's Very Large Telescope have ...

Hubble sees a unique cluster: One of the 'hidden 15'

(Phys.org) —Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, ...

Hubble finds appearances can be deceptive

(Phys.org)—Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high ...
