    Notes: [Auszug] A few decades ago, astronomers thought they knew what galaxies were and what they were made of, if not how they got there. But as so often happens, new discoveries and contemplation reveal our ignorance. So, in the last two decades, confusion has increased concerning the contents and behaviour of ...

New evidence has been reported1 that the Seyfert galaxy NGC 6814 varies on the amazingly short time ...
