Some Galaxies Can Be Thrown Away From Their Host Clusters

Astronomers think, that there are dozens of billions undetectable free floating planets that straggle along our Milky Way galaxy, being not gravitationally bound to any star.

Hubble's 25th Anniversary Celebrated with Vibrant Image of Westerlund 2 Star Cluster

The glittering tapestry of young stars flaring to life in this new NASA/ESA Hubble Space Telescope image aptly resembles an exploding shell in a fireworks display. This vibrant image of the star cluster Westerlund 2 has been released to celebrate Hubble's 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science.

Astronomers Spot 11 Galaxies Exiled From Their Clusters

We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.

Physics Framework Underlying Unexpected Metal-to-Insulator-to-Metal Transitions

New work from Carnegie’s Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.

Close Investigation of Two Very Different, Distant Dwarf Planets

The solar system is teeming with tiny rocks – but officially there are only five dwarfs: Ceres, Eris, Haumea, Makemake and Pluto. While the Dawn space probe is currently exploring Ceres, the New Horizons mission will hurtle past big brother Pluto on 14 July and record data and images of this faraway world en passant. The researchers will thus have a chance to more closely investigate two very different, distant dwarf planets.

Spin Phenomena Interdisciplinary Center Opens at Johannes Gutenberg University Mainz

Johannes Gutenberg University Mainz (JGU) today officially opened its new Spin Phenomena Interdisciplinary Center (SPICE), which will facilitate interactions between the many diverse fields that study spin-related phenomena – at a level that each field could not achieve on its own.

Researchers Await First Light of ESPRESSO Spectrograph on ESO's Very Large Telescope

The exoplanet 51 Pegasi b [1] lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found orbiting an ordinary star like the Sun [2]. It is also regarded as the archetypal hot Jupiter -- a class of planets now known to be relatively commonplace, which are similar in size and mass to Jupiter, but orbit much closer to their parent stars.
