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. Koss (ETH Zurich) et al.

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

Bizarre black hole alignments over billions of light-years

The black holes are central to quasars in the early universe. Researchers say the probability that their aligned spin is the result of chance is less than 1%.

Venus because it is so close to the Sun at 0.7 AU. At that distance, the solar storms are so strong that it may not matter if there's not planetary magnetic field, the charged particles would be deposited all over the planet, producing auroras at every latitude. Illustration by C. Carreau/ESA
