An ultraluminous quasar with a twelve-billion-solar-mass black hole at redshift 6.30

The most luminous quasar  (quasi stellar radio sources) currently known is reported in the latest version of  Nature.
At the "borders" of the universe, 12.8 billion light years from earth, only 900 million years after the big bang this Quaser was formed. The massive black hole has a mass of 12 billion solar mass. It's not the most massive one (cfr 39 billion solar mass) but in comparison with the black hole in our milky way of 4.1 million solar mass, it's gigantic.

Venus and Mars at the evening sky

The weather conditions are far from ideal with the upcoming fog.  I was able to oberve both Mars and Venus at the evening sky 1h after sunset and low in the West. The next days both Mars and Venus will be closer at the sky - hopefully we can observe this as weather forecast doens't look good.
