A new record for the most distant quasar
Astronomers have a new measurement for the distance of quasar J0313-1806, making it the new record-holder for the most distant quasar known. We’re seeing it just 670 million years after the Big Bang, or more than 13 billion light-years away. Source: https://earthsky.org/space/new-record-most-distant-quasar-black-hole-j0313-1806…

The Milky Way may have less dark matter than astronomers thought
Our galaxy may have slightly less dark matter than expected from theoretical estimates, according to a measurement of the acceleration of rapidly spinning stars Source: https://www.newscientist.com/article/2264579-the-milky-way-may-have-less-dark-matter-than-astronomers-thought/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Image: Hubble views a dazzling ‘fireworks galaxy’
The galaxy NGC 6946 is nothing short of spectacular. In the last century alone, NGC 6946 has experienced 10 observed supernovae, earning its nickname as the Fireworks Galaxy. In comparison, our Milky Way averages just one to two supernova events per century. This NASA/ESA Hubble Space Telescope image shows the stars, spiral arms, and various stellar environments of NGC 6946 in…
