Stars
The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth. New research shows that half of those stars might have been ripped from another galaxy.
Would it be possible in the real world?
The sheer observing power of the NASA/ESA Hubble Space Telescope is rarely better illustrated than in an image such as this.
An international team of scientists, including researchers from the University of Chicago, has made the rare discovery of a planetary system with a host star similar to Earth's sun.
For the first time, scientists have seen how a powerful whirlwind shot out from the rotating disc of gas and dust surrounding a young star.
The constellation of Virgo is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1,300 galaxies called the Virgo Cluster.
VLT observations of neutron star may confirm 80-year-old prediction about the vacuum.
The discovery has shed new light on the origins of globular clusters -- which are concentrations of typically a million stars, formed at the beginning of the Milky Way's history.
