A collection of articles with an astronomical theme that don´t fit in another category.
A Quick Guide to the Astronomy Site
What are other people reading? Where can I find an astronomy word search? I'd like some help to start observing. What is a meteor shower? Here is a guide to help you find what you want and get the best out of the BellaOnline Astronomy site.
Aries the Golden Ram
Aries was the winged ram from which the Golden Fleece came. Two thousand years ago his constellation marked the spring equinox when the Sun crossed the celestial equator near Beta and Gamma Arietis. The equinox is now in Pisces, but what strange object was discovered in 2007 in Aries?

Cats in the Sky
There are three constellations named for dogs, but what about cats in the sky? There is astrocat Felicette who went into space and returned safely to Earth, but also constellations of big cats and a pawprint 50 light years across.
Celestial Sleuth – book review
A "celestial sleuth" solves puzzles in art, history and literature using astronomy. Why did Munch have a blood-red sky in "The Scream"? How did British sentries miss Paul Revere rowing across Boston Harbour under a full Moon? Which meteor shower did the characters in James Joyce´s "Ulysses" see?
We no longer see the heavens as perfect and the stars as eternal and unchanging. Even the Universe had a beginning, and everything that we observe changes and evolves. Many of these changes involve cosmic collisions.
Horses galloping and flying; creatures half human, half horse; dark horses invisible but for their silhouettes against the stars behind them. Find out about the cosmic equines that are features of our skies.
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.
Distances in Space
You wouldn´t want to know the distance from Boston to San Francisco in inches. And for the same reason, miles aren´t very useful in space. After all, it´s 26 trillion miles to the next nearest star. So how do astronomers deal with these enormous distances?
Gravity - Cosmic Glue
Aristotle's perfect cosmos didn't need gravity to hold it together. However a system with planets orbiting the Sun called for an explanation. In the process, Newton was inspired by a falling apple, but Galileo's experiments with falling bodies didn't involve dropping them off the Tower of Pisa.
How to Tell a Planet from a UFO
Two English policemen chased a UFO through the Devon countryside. It was the planet Venus. A news reporter had quite a scoop when she found a UFO hovering over New York City. It was the planet Jupiter. Why are planets and stars often mistaken for spacecraft or aircraft?
Light pollution isn't just a problem for astronomers. It means the loss of an amenity for all of us now and the generations that follow. It affects the natural world, can ruin our health, wastes resources, and what's more, we're paying for it!
Light Pollution - Facts for Kids
Thieves are stealing something that belongs to you. It´s something you inherited from countless generations of your ancestors: a view of the night sky. The unnecessary lighting that hides it also damages wildlife, increases air pollution and can damage your health. What can we do?
Merlin´s Tour of the Universe - book review
Does the Earth really wobble on its axis? How does the Sun make its heat? What would happen if I fell into a black hole? If you want to know the answers to these and many other questions, this book is a good collection of the things that people have asked "Merlin."
How much do people know about our next-door neighbor the Moon? For example, does the full moon drive people crazy? Apparently not - unless maybe they're astronomers trying to observe faint nebulae. Here are ten common moon myths and lunar lapses.
NASA Helped Rescue Chilean Miners
In the Chilean winter of 2010 thirty-three miners were trapped half a mile below the surface. They were in a hostile environment, a confined space, reliant on supplies from outside - similar to the problems of a space mission. Find out how NASA's decades of experience helped the Chilean rescuers.
Night Sky Olympic Tribute
Planet Earth presents a grand international sporting spectacular every four years, the Olympic Games. Even if you're not fond of sports, it's a majestic pageant and a set of unfolding dramas that a scriptwriter couldn't hope to emulate. Here is my astronomical tribute to this magnificent saga.
Phantom Planets and Moons
Moons of Venus and Mercury? An unknown planet nearer the Sun than Mercury? Astronomers can misinterpret what they see, too. Happily, other observers, better instruments and new theoretical understandings can put it right. Here are some phantom objects that many astronomers once thought existed.
These articles contain a wide selection of astronomical information, but each is based around a seasonal or topical theme.
Star-gazing – Seeing in Dim Light
How can you see an object by not looking at it? Why do aurorae and deep-sky objects tend to look grey? How can an eyepatch and a red flashlight be useful to an astronomer? Why can a camera flash ruin a night's observing? Answers to all these questions are related to the way our eyes react to light.
Tales of the Northern Lights
The aurora is an ethereal, shifting light in the northern sky and is associated with many tales and beliefs. It can look like the dawn, so Galileo named it after Aurora goddess of the dawn. It has reminded others of dragons, spirits, dancers, shield maidens, herrings or the legendary fire fox.
The Bluffer´s Guide to the Cosmos - book review
Here is an entertaining overview of astronomy small enough to put in your pocket. Not only the Big Bang, black holes, exploding stars, visiting Mars and all the rest of the cosmos, but plenty of laughs along the way. I enjoyed it - you must know someone who would too.

Top Ten Astronomy Stories of 2013
What were the big astronomy events of 2013? Here are my top ten choices and they include a big bang over Russia, a Moon goddess and Jade Rabbit, a telescope in the high Andean desert to look for the first galaxies, and the launch one of the most ambitious space missions ever.
What's in a Name
Things aren't always what they seem. Many discoveries aren't named for - or by - their discoverers. Halley didn't discover Comet Halley. Kuiper said the Kuiper Belt didn't exist. The Herschels called Uranus "the Georgian planet" after George III of England, but no one else did.
Who Let the Dogs out? Astronomy Homepage | Editor's Picks Articles | Top Ten Articles | Astronomy Site Map
Someone must have left the door open, because the skies are full of dogs. You can see the dogs of Orion and the hunting dogs of the shepherd Bootes in pursuit of the Great Bear. There is also the Running Dog Nebula and the memory of poor Laika, the first cosmonaut, who perished in space.
