HORSEHEAD NEBULA A dark nebula in the constellation Orion, located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. SUPERNOVA A supernova is an astronomical event that occurs during the last stellar evolutionary stages of a massive star's life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. This causes the sudden appearance of a "new" bright star, before slowly fading from sight over several weeks or months. INTERSTELLAR CLOUDS OF DUST Most nebulae are of vast size, even millions of light years in diameter. Contrary to fictional depictions where starships hide in nebulae as thick as cloud banks, in reality a nebula that is barely visible to the human eye from Earth would appear larger, but no brighter, from close by. HELIX NEBULA The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae. PLEIADES In astronomy, the Pleiades, or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

    At the end of March, my long-time Chinese assistant set up her own business and started working in her home office. It was a big leap forward for her, but for me it was a great loss. Apart from a few years, she worked part-time as my assistant for about 15 years. For the last…

    Purification

    Two weeks ago, I followed a YouTube live stream about blue tits’ first flight to the outside world after three weeks of nest box breeding. The walls of the box were reflecting light, which distracted the baby birds, and they jumped arbitrarily onto the walls of the box in search of a way out. In…
