November 25th: Showing the Family Around the Night Sky
http://365daysofastronomy.org/2010/11/25/november-25th-showing-the-family-around-the-night-sky/Alright lets go back to Polaris so we are again facing due North. Three fists to the 1 o’clock position of Polaris is the ‘W’ or the ‘M’ of Cassiopeia. A little distorted but very distinctive. I want to use the right most segment of the ‘M’ as a ruler. So note that distance. Just mentally note the distance, and gaze to the right of the star at the end of the segment that distance. There if your skies are dark enough, you’ll find a hazy spot or spots that is known as The Double Cluster. This is two clusters of faint stars close enough together to make them just able to be seen as one or two hazy patches to the unaided eye.

Sunset on Mars
I know, it may not look like much, but think about what you’re seeing: a sunset on another world. And those images were taken by a robotic probe that took years to design and build, months to travel the hundreds of millions of kilometers to get to Mars, a harrowing few minutes to descend on a breath of fire through the thin air to land on the surface, and then
nearly seven years to travel the landscape long, long past its design
specifications…

If you can see these on a large screen monitor, Do.
I like “Husband Hill Summit”
The Bounce marks on “Mars Opportunity, Eagle Crater” are cool too.

Bucket List for Backyard Stargazers #5 – A “Meteor Storm”
Bucket List for Backyard Stargazers #5: A “Meteor Storm”
November 16, 2010
A meteor storm! The very term makes an honest stargazer’s heart beat faster. While a good meteor shower, like the Perseids, may show 50-60 meteors every hour, a meteor storm sprays shooting stars at a rate of hundreds or thousands an hour. During a spectacular storm in 1833, the sky seemed to “fill with falling fire” for nearly half the night…

Earth’s dust tail points to alien planets
November 15, 2010 By Dauna Coulter
Did you know that the Earth has a dust tail? The Spitzer Space Telescope sailed right through it a few months ago, giving researchers a clear idea of what it looks like. That could be a big help to planet hunters trying to track down alien worlds…

Cosmic births revealed by disks of dust
November 15, 2010
By carving ‘gaps’ in the disks of dust that create and enshroud them, newborn planets are giving astronomers clues to locating possible new worlds.
An international research team, led by Swinburne University’s Associate Professor Sarah Maddison, is studying the disks of dust that enfold newborn planets in order to better understand cosmic birth…

How Will We Get to Mars?

How Will We Get to Mars?
There has been a lot of discussion over the last couple of weeks about sending men to Mars. It has been a goal of NASA’s space program for a while now, and there has even been discussion about sending astronauts to live on the surface of the red planet permanently.
But all of this raises an interesting question; how will we get there?…

Which planets might support life? – feature
Epsilon Eridani b is the closest known exoplanet to Earth, orbiting a Sun-like star about 10 light-years away.
Gliese 581 is a modest star lying in an unfashionable part of the constellation Libra. It is dim, small and even though relatively close to Earth, cannot be seen by the naked eye. It is, to put it simply, insignificant – the Crouch End of interstellar real estate. But astronomers have recently found that it possesses an intriguing secret. In 2009, observations showed that the star has a family of five planets, including at least one body roughly the same size as Earth…

Time Travel on a Cloudy Night…
November 11, 2010
I was going to suggest you inspect a lovely double star in Andromeda this weekend, but November weather is clouding out many stargazers.
So let’s do something completely different. Here’s a video featuring an old colleague of your humble publisher from many years ago, Dr. Jaymie Matthews of the University of British Columbia. In this video, based on the 2008 movie Stargate:Continuum, Jaymie explains the possibilities of time travel.
(Warning: there are a couple of spoilers for the Stargate:Continuum movie in this video, so beware if you plan to see it…)
The whole video is fascinating. But even the first couple of minutes will change your perspective on time travel, and maybe leave you a little wistful…
