Sagittarius the Archer
In northern hemisphere summer, the ancient zodiac constellation Sagittarius stands low on the southern horizon. It's a special constellation, for when you see Sagittarius, you're looking into the heart of the Milky Way.
ABC of Astronomy – A Is for Astronomy
In the ABC of astronomy, astronomy itself is the first and most important item. What is astronomy and how does it differ from astrology? What are the main specialist areas in astronomy and how do they contribute to the overall picture?
Obsolete Constellations
What happens to constellations when you don't want them anymore? Nothing, physically. They aren't real groups of stars like star clusters are. They're the products of human imagination, and they come and go. Here are half a dozen of my favorite obsolete constellations.
Beagle 2 – Lost and Found
On Christmas day 2003 a British-European space probe called Beagle 2 was lost on Mars and never heard from. It was not only small, but possibly broken and scattered while attempting to land. Since Mars is quite big, it took eleven years to find the little lander.
Syzygy - When Heavenly Bodies Align
Syzygy may look like the letters on a dreadful Scrabble rack, but it just means three heavenly bodies lined up. When this happens, there are eclipses, transits, conjunctions, oppositions and occultations.
Top Five Dubious Astronomy Stories 2014
Have you read about the Top Ten Astronomy Stories for 2014? This article is complementary to it. Here are my choices for the top five debatable stories of the year. They were widely reported, but there isn't yet enough evidence to accept their conclusions.
Top Ten Astronomy Stories 2014
What happened in the skies in 2014? Here's my top ten. Some hints: it takes in stories all the way from a tiny lander alone on a comet to a supercluster of galaxies 500 million light years across, perhaps another Earth, and an ocean on one of Saturn's moons.
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?
Natural History Museum London - Astronomy Tour
How about an astronomy tour of the Natural History Museum in London? It won't take more than 13.8 billion years – or much less, as your watch measures it. Highlights will be the evolution of the Earth, and pieces of Mars and the Moon, one of the oldest known meteors, and diamonds from stardust.
How Big Are the Biggest Stars
What is the biggest star yet discovered? It's harder than you might think to answer this question. But here's a short tour of big, bigger and absolutely enormous stars - including some impossible ones.
