This date in science: Edwin Hubble and the expanding universe

Hubble helped change our cosmology: our idea of the universe as a whole.

Using the Keck II telescope in Hawaii, researchers obtained high-resolution images of Markarian 177 and SDSS1133 using a near-infrared filter. Twin bright spots in the galaxy's central region are consistent with recent star formation, a disturbance that hints this galaxy may have merged with another. Image credit: W. M. Keck Observatory/M.

Is this exotic object an ejected black hole or a huge star?

Is SDSS1133 a supermassive black hole ejected from its home galaxy, or the remains of a massive star that exploded as a supernova? Astronomers aren’t sure.

View larger. | This artist's impression shows schematically the mysterious alignments between the spin axes of quasars and the large-scale structures that they inhabit that observations with ESO’s Very Large Telescope have revealed. These alignments are over billions of light-years and are the largest known in the universe.  The large-scale structure is shown in blue and quasars are marked in white with the rotation axes of their black holes indicated with a line.  This picture is for illustration only and does not depict the real distribution of galaxies and quasars.  Image via ESO/M. Kornmesser
