By studying the motion of the Milky Way's stars, researchers have learned there is not a lot of evidence for dark matter around the Sun. Current hypothesis have the solar neighborhood teeming with dark matter - an invisible enigma which is detected through its gravitational force. However, new research done by a team of astronomers in Chile have pointed out that the theories just don't match the facts. Chances are good that we'll never be able to directly detect dark matter particles with terrestrially based equipment.

Greetings, fellow SkyWatchers! What a great week to just enjoy some great unaided eye astronomy observations. Who can resist the beautiful appearance of Mars in Leo? Also this week, you'll enjoy not one - but two - meteor showers as the Mu Virginids come to town mid-week and the Bootids light up the weekend. Get ready to enjoy bright stars, find planets, explore lunar features, learn some astronomy history and much more! When ever you're ready, meet me in the back yard...

No matter where we live, both professional and amateur astronomers alike are keenly aware of light pollution and its affects. Not only does artificial lighting wash out the natural beauty of the starry night sky, it is responsible for environmental problems which can hamper everything from hatching sea turtles to migrating birds. Even though it’s a scary situation, it is one than can easily be solved by using common sense and shielded lighting. But how do we get people to become aware of the problem?

Greetings, fellow SkyWatchers! It's going to be a great - and dark - week to enjoy astronomy! We'll start off with an impressive galaxy for even small optics and enjoy two meteor shower. There's planets and planetary nebula to explore, as well as some awesome globular clusters. If you're in the mood, there's some history to learn and plenty of astronomy facts! Whenever you're ready, meet me in the back yard...

Over the last three decades astronomers have seen thousands of comets falling into the Sun. For the most part, they’re too small to survive a close approach – let alone re-emerge. It has only been within recent years that these icy travelers have been observed near the glaring Sun. Now a team of scientists led by Professor Emeritus John Brown, Astronomer Royal for Scotland and former Regius Professor of Astronomy at Glasgow University, have been able to pinpoint which ones are destroyed high above the solar atmosphere, which ones are annihilated just above the surface and which ones make it through their hellish journey.

Even though it has been some four decades since the Apollo mission returned to Earth with their precious cargo of lunar soil and rock samples, these old samples are still teaching us new things. According to a recent study of Moon matter, the chemical signature blows away the common theory that the Moon was a product of a collision. According to the giant impactor scenario, the Moon may have formed when Earth and a hypothetical Mars-sized body referred to as “Theia” collided some 4.5 billion years ago. However, graduate student, Junjun Zhang of the University of Chicago, may prove otherwise. By analyzing the titanium content of lunar samples, Earth and meteorites, she speculates the Moon’s composition comes solely from Earth.

Greetings, fellow SkyWatchers! Despite the Moon, it will be a great week as the month of April opens with two meteor showers. The planetary action doesn't stop, because Venus is about to become a "guest star" in the Pleiades! Need more? Then know it's the right time of year to spot aurora - and to gather photons from bright star clusters! Get out your binoculars and telescopes and meet me in the back yard...
