Eclipse Pictures!

You didn't need a telescope to see last week's lunar eclipse.  Photographer Sjoerd Witteveen took this series of pictures showing the progression of the eclipse over the evening and these images are similar to what you could see with the naked eye.  My favourite part is seeing the early stages when the moon appears to have a bite taken out of it.  As things progress and the moon enters the full shadow of the earth, you see an orangey red hue cast upon the lunar surface.  The colour is due to refracted sunlight bending around the edges of the earth and reaching the moon.  Just imagine, that's all the sunsets and sunrises on earth at that moment painting our Luna in a beautiful light!

This weekend from Friday February 29th to Sunday March 2nd, I'll be at the Markham Spring Home Show .  If you would like to learn more about astronomy I'll be at the Starlight Learning booth.  In addition, I'll be making a presentation on "Backyard Astronomy" during two public lectures at the Home Show stage at 6:45 PM Friday and 5:45 PM Saturday.

An Eclipse of the Moon on Wednesday February 20th!!

Here's an opportunity to see an eclipse of the moon!  Check out our skies on the evening of Wednesday, February 20th to see the Moon enter the Earth's shadow.

What's interesting is the reddish hue you will see as the event progresses.  This colour is due to the light of sunrises and sunsets on the Earth which manage to refract around our atmosphere and continue to the moon.  Unlike an eclipse of the sun, an eclipse of the moon is safe to view with the naked eye.

Start looking around 8:15 PM Eastern Standard Time and follow the progress of the eclipse as the shadow of our Earth travels across the lunar terrain.  As the Moon enters the darker umbral shadow around 8:43 PM, you will see the red colour start to fill the landscape.  By 12:30 AM, it should be all over for the last total lunar eclipse until the year 2010.

Remember to dress warmly and have the hot cocoa ready.

Crunch Time for Canada's Biggest Telescope

When it was completed in 1935, it was the second largest astronomical telescope in the world.  The 74 inch reflector was used by astronomer Dr. Tom Bolton to confirm the existence of Cygnus X-1 as a Black Hole, a first in astronomy.  Dr. Helen Sawyer Hogg contributed to our understanding of the universe by the decades of research at the David Dunlap Observatory's mighty telescope.  The 190 acres of surrounding undeveloped land are home to deer and over dozens of species of birds.  It's an oasis of astronomy and biology surrounded by the suburbs of Toronto.

The University of Toronto intends to sell the DDO and the surrounding wild space and fetch as much as $100 million dollars in the process.  Will we see it snapped up by developers keen on turning the land into houses, offices and strip plazas?  I hope not.  There's a strong community voice in Richmond Hill, including Mayor Dave Barrow who wants to see the site preserved.  Local government along with community groups such as the Richmond Hill Naturalists have mounted a campaign to offer the U of T a serious alternative to the dismantling and destruction of the DDO.  We know that this is the right thing to do. The David Dunlap Observatory represents a major piece of the history of astronomy,  as well as the history of Canada. 

We can do our part to help but we must act quickly.  The University of Toronto has placed a deadline of February 15th, 2008 to decide on submissions for the sale of the facility.  Let them know that you want the DDO to remain as a testament to the advancement of the science of astronomy, a part of our heritage and that it should be preserved.  Take a moment and fill out this online petition. 

Thank you and clear skies!

See a Comet Tonight!

It's an exciting time when a comet becomes visible to the naked eye.  Right now the opportunity to exists to see Comet 17P Holmes, now visible in the constellation Perseus.  This came to us as a surprise because until late last week it was all but invisible to all but the most powerful telescopes.  Literally overnight, the comet brightened by a factor of one million and of course we're excited.  Right now, you have the chance to see it as a fuzzy, yellowish star.

Where can you see Comet Holmes?  Easy.  Take a look at the clip above, originally posted on AstroShorts.

Jupiter and the View from Here

Jupiter from Oshawa Ontario October 8th at 8 PM.  (Click on picture to enlarge)

October marks the final days of viewing the summer delights.  Take a look to the southwest after dark.  Scorpius is diving below the horizon with the gas giant planet Jupiter shining like a bright star immediately above.  The teapot which designates Sagittarius also marks the location of some of my favorite objects.  This region is rich in nebulae -stellar nurseries of incredible detail- and both open and globular star clusters.

Now let's take a look at the skies in New Zealand.  It looks totally different doesn't it?  Take a look at the top of the second picture and you can see that teapot shape of Sagittarius, now inverted for us Northern Hemisphere residents.  Near the center of the picture is Jupiter again.  The skies of the Southern Hemisphere are seen from a totally different perspective and most of us from the Northern Hemisphere usually have a hard time adjusting to the new view.  Of course, if you live in Wellington New Zealand, it's us Northern types that have the odd looking skies.

The Birth of the Space Age

Sputnik 1 was the first man-made satellite.  Launched on October 4th, 1957 by the Soviet Union, Sputnik was outfitted with a simple transmitter which announced the presence of man in space.  The space race it spawned and its associated technological leaps and sprints have defined much of the latter half of the 20th century.  You can argue the benefits and the potential threats of life in the post-Sputnik age but you cannot deny that the world changed on that date.  The world became a small place.  A more dangerous place.  And to me, a more hopeful one as well.

Sky Events for October

It's Aurora Season!

Image Credit:  SOHO

This picture of the sun was taken by the SOHO space observatory and shows what is known as a "Coronal Hole".  Basically, it's an area where the magnetic field doesn't loop back into the sun but extends out into space along with the solar wind continually streaming from the sun.  This process allows charge particles to escape and travel with the stream.  Why is this important?  Well when these particles reach Earth's magnetic field there's an interplay that may result in a show of the Northern Lights.  If you have a chance tonight and tomorrow night take a look outside around midnight.  If you are looking northward and have dark skies you might just be rewarded with nature's light show.

End of an Era

The David Dunlap Observatory was one of the world's leading facilities in Astronomical Research.  Situated in Richmond Hill, it provided Canadian researchers the ability to explore the universe since the 1930's.  A lot of real scientific discovery went on at the 74 inch reflector telescope, once considered a Goliath.  Now, it is a victim of progress.  Light pollution from urban growth coupled with more advanced and more capable designs made the DDO less and less important.  It's hard to justify spending $800,000 per year to operate something that now offers minimal returns.  The shame here is that we could have had gone further with the present facility if the political will existed on all levels of government to use better municipal lighting.  Still, it had to happen eventually.

The facility was a gift to the University of Toronto from Jessie Dunlap in memory of her husband.  The university recently announced that it has reached an agreement with the grandchildren of Jessie and David which allows the closure of the facility and sale of the lands and equipment.  A new facility built with the proceeds will be called the Dunlap Institute.  It will support future astronomical research from the U of T's St. George Campus.  Final vote is expected in early October.

It is sad that this jewel will go missing from Richmond Hill.  A piece of history will be lost.  Progress is like that though; some good with the bad.
