The southern Milky Way can be so bright that on a clear moonless night it will cause shadows, yet it is something people living in the northern hemisphere only hear stories of. In the same way, the beauty and objects of the northern sky are a mystery to southern residents.

“Big Dipper to Southern Cross” brings these two hemispheres -- truly “One People, One Sky.”

For this project there will be two telescopes -- one in the northern hemisphere and one in the south -- on two different nights. No experience is needed. This is a chance to watch as an experienced telescope operator and guide show how they capture the wonders of the night sky.

Join other members of AWB Affiliates around the world. Chat will be available between participants and with the telescope operator. Join in or just watch.

This photographic panorama from the summit of Mauna Kea, Hawaii, shows stars of both the northern and southern skies. The Big Dipper is behind the dome of the Canada-France-Hawaii Telescope on the left, with Polaris and the Little Dipper visible just to the dome's right. The Southern Cross is just to the left of the Gemini North Telescope, seen on the photo's right. The central bulge of our Milky Way galaxy dominates the view between them.

To take part in the observing sessions:

How: All you need is a computer connected to the Internet, with loudspeakers or headphones.

You need to have the free Flash plugin installed. If you can see and hear videos on YouTube then your system is ready. You can test this as well by going to the Virtual Telescope page -- if you can see the small video in the upper left corner then your system is ready to use. More than 95% of computers already have Flash installed.

Where: Go to the Virtual Telescope's Big Dipper to Southern Cross page at the dates and times of the event (see times and dates below).

When: See the times of the two session below. Not sure when that is in your time zone? Go to the World Clock Time Zone Converter to convert these times to your local time zone.

In case of bad weather at the observing stations the event will be run using backup images or rescheduled. Watch this page for updates.

Global Pairing Program

As our world grows ever more complex, we are seeing the pace of scientific discovery quicken, especially in our understanding of the Universe and ability to explore the night sky with new technologies and techniques. Taking advantage of these rapid changes in astronomy becomes ever more challenging, especially for new and growing international astronomy clubs in developing countries. Many of the world stargazing clubs are filled with eager members who are new to the hobby of astronomy, while those in Europe and North America predominantly have more seasoned members willing to share their passion for the night sky. That is ...

The Day The Earth Smiled

Cassini 's portrait of Earth on July 19, 2013 The world watched on July 19, 2013, as NASA’s Cassini spacecraft snaps Earth's image from the far side of Saturn. With the brilliant light of the Sun blocked by Saturn itself, the ringed planet loomed large in the foreground, with Earth appearing as a very distant "Pale Blue Dot." “It was a day for all the world to celebrate,” said Cassini imaging team leader Carolyn Porco of the Space Science Institute in Boulder, Colorado, who first recognized the unique opportunity to create this new view of Earth. AWB was proud to ...
