The Japanese spacecraft Akatsuki has been orbiting Venus since 2015. It carries an infra red camera that captures coud morphology – even at lower cloud levels.
At https://www.jpl.nasa.gov/news/ … a mysterious blast in space caught the attention of astronomers and became a focus of NASA telescopes. It is being called the AT2018cow – and yes, a cow. It was a brief and unusual flash spotted in the sky back in June. It has become known as 'the Cow' after the final letters in its official name. Over 3 days the Cow produced sudden explosions of light ten trimes brighter than a typical supernova. It then faded over the next couple of months. However, it had formed close to a star forming galaxy in the constellation of Hercules. Since then we have had a number of papers theorising on what the Cow may represent – from black holes breaking apart to black holes farming, to black holes in a feeding frenzy – or even a black hole colliding with itself.
