Quasar

Astronomers have discovered a distant, massive and ancient black hole that calls into question current models for the early expansion of the universe. A team of scientists from China and Arizona spotted the brightest quasar from the early universe, named SDSS J0100+2802, centered on a black hole 12.8 billion light years away and as bright as 420 trillion suns.

Astronomers using the ESO’s Very Large Telescope (VLT) in Chile have discovered an unexpected alignment of the spinning axes of supermassive black holes located billions of light-years apart. As if that discovery wasn’t fascinating enough in itself, the team then delved a little deeper, finding that the quasars aren’t just linked to each other, but are also aligned with the large-scale structure of the Universe itself.

Honda, the world’s largest motorcycle manufacturer, has announced a new motorcycle – the 750 cc NM4 Vultus – and it's a bold departure from tradition with anime/manga styling, a "fighter pilot" feet-forward riding position, an ultra-low seat and advanced electronic rider assistance to make it easier to ride. This is a motorcycle aimed at the next generation of motorcycle enthusiast raised on video games and a different visual vocabulary. If you are a traditionalist, you'll probably hate it. Read More
That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a great deal of evidence for this has accumulated, visual evidence has been difficult to find. Astronomers have now photographed what appears to be a segment of a cosmic filament stimulated into fluorescence by irradiation from a nearby quasar. Read More
Our knowledge of the large-scale structure of the Universe is gradually taking shape. However, our improved vision is mostly being statistically squeezed from huge data sets. Working backward from a statistical analysis to a putative fact about the (singular) Universe, to which statistics do not apply on a cosmological scale, is a dicey business. A case in point is a recent look at the biggest known structures in the Universe – large quasar groups. Read More
The Gaia mission to map a billion stars in the Milky Way has been delayed for about two months by the European Space Agency. Problems in X-band transponders used in other satellites have begun to appear, and the ESA has decided to replace those modules prior to launching. The likely blastoff date will be in late December of this year. Read More
Gravitational lenses, which are massive galaxies or galaxy clusters that act as a magnifying glass by bending light passing them, are one of the Universe's golden gifts to astronomers. To help unlock the mysteries that might lie behind these untapped celestial resources, Zooniverse, a program of the Citizens Science Alliance, has begun the Space Warps project. It allows citizen scientists to put their skills at pattern/image recognition to use, toward finding these fugitive gravitational lenses. Read More
