Cosmic Ghosts Ghouls and Vampires
Astronomers use colorful language for cosmic objects. But unlike ghosts, ghouls and vampires in horror stories, the cosmic ones aren't scary late at night. Here are tales of the birth, evolution and death of stars, a blinking demon and a star that, at Halloween, seems like the Sun's ghost.
Cosmic Halloween Tour
Join me on a Halloween astronomical tour. See a cosmic witch and cosmic ghosts, spiders and snakes, and fiery skull. But have no fear. It's a virtual tour and all these objects are a very long way away.
Valentine's Day is no assurance that love is in the air. Hearts and flowers aren't guaranteed to come your way. You may or may not get one of the billion valentine cards that are sent each year. But heart shapes are everywhere and anyone can admire them. Here is a cosmic selection for everyone.
Cosmic White Christmas
If you're dreaming of a white Christmas, the cosmos may have something of interest. How about deep snow on one of Saturn's moons, a gigantic Christmas tree whose lights are baby stars, a snowman on an asteroid, or an Einstein ring?
Cosmonauts - Birth of the Space Age
The starter's pistol for the space race was fired on October 4, 1957. It was in the form of a small highly-polished sphere that orbited the Earth every 98 minutes. This was the Soviet Union's Sputnik, Earth's first artificial satellite. It shook up the United States, and there was more to come.
Could you survive unprotected in space
Movies show people being expelled unprotected into space - they explode, they freeze instantly, their blood boils. It's not a pretty sight. Would this actually happen? Not really, but I still wouldn't recommend trying it out.
Creepy Crawlies in Space
What was the first Earth creature to go into space? Not a dog, but a fruit fly. Insects and arachnids have been mini-astronauts for over sixty years. They have also inspired the naming of heavenly objects.
Crux – the Southern Cross
Crux is the smallest of the 88 constellations, but it punches above its weight. As Polaris does in the northern hemisphere, in the southern hemisphere the Southern Cross serves as a navigation aid. It's part of the flags of five nations, and its stars also feature widely in traditional lore.
Cygnus the Swan
Seduction and supergiants, a beautiful blue and amber double star, vast explosions, a giant cloud that looks like North America. Where does myth end and astronomy begin? Here is a tour of some of the highlights of the constellation Cygnus the swan.
Dark Matter - Poems of Space - book review
What do poets see when they look at the heavens? And astronomers? Are the experiences completely different or different sides of the same sense of wonder? This collection of poems, edited by a poet and an astrophysicist, is a treasure trove. There's something here for everyone.
