Doodles for Women Astronomers
Since 2013 four outstanding women astronomers have been honored by a Google Doodle. None of the Doodles have had a worldwide reach, but there is a link to each delightful drawing and I've given some biographical details. Read on to meet this stellar quartet.
Dorado the Mahi Mahi
Since the heavenly flying fish (Volans) is intact, its neighboring constellation Dorado must still be hungry. Dorado is a dolphinfish, mahi mahi being the most common type. Mahi mahi pursue flying fish through tropical seas, and you might imagine Dorado chasing Volans through the southern skies.
Draco the Dragon
An enormous dragon circles the northern celestial pole. The constellation Draco contains a star that was the pole star at the time of the pharaohs, some interesting galaxies and the most complex planetary nebula yet discovered.
Dwarf Planet Tour for Kids
After all the fuss about Pluto, everybody knows that it's a dwarf planet now. But it's only one of five. Here's a mini tour of all five, including the one where a heatwave is the temperature of Antarctica, the one shaped like an egg, and one whose year is over 500 Earth years long. All aboard!
Dwarf Planets - a Tour
Join the dwarf planet tour. It will take you so far away that the Sun seems to be no more than another bright star. You'll see a dwarf planet the shape of an American football, one whose a month is the same length as its day, and the one that upset the fans of Pluto.
In the darkness of space we see the part of the Moon that the Sun illuminates. But sometimes there is a bright crescent Moon with a dark shadow filling in the rest of the Moon's face. What lets us see the Moon's night side, and how might the phenomenon detect life on distant worlds?
Ecliptic and Equinoxes
The objects in the night sky seem to be projected onto the celestial sphere. A coordinate system lets us say where everything is, but something's not quite right. The north polar star will be Vega one day. Astrological star signs don't match the constellations any more. What's going on?
Edge of the Sky – book review
Robert Trotta lectures in astrophysics at Imperial College London. He's also a science communicator who likes to share his knowledge with the public. So he set himself the task of writing about the Universe using only words from a list of the 1000 most common English words. How did he do?
Halley didn't discover a comet, but he did research and published papers in astronomy and many other fields. Russian Czar Peter the Great liked him as a dining and drinking companion and King William III put this civilian in charge of a Royal Navy ship. But how did he get a comet named for him?
Edward Charles Pickering
Edward Pickering was a leading light of 19th century astronomy who made the Harvard College Observatory into an institution with an international reputation. He was honored for his work by scientific societies in several countries, but his name is now known from his employing “Pickering's harem”.
