Wow… If you had a chance to watch our live remote telescope today, then you were in for an awesome view of the Tarantula Nebula! Although it didn’t last very long before the dew and clouds chased us out, we were still able to take some great images and run some video footage for you to enjoy. Are you ready to have a look? Then step inside the library and brush away the cobwebs…
The Tarantula Nebula (also known as 30 Doradus, or NGC 2070) is an H II region in the Large Magellanic Cloud. It was originally thought to be a star, but in 1751 Nicolas Louis de Lacaille recognized its nebular nature.
The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 180,000 light years, this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows. In fact, it is the most active starburst region known in the Local Group of galaxies. It is also the largest and most active such region in the Local Group with an estimated diameter of 200 pc. The nebula resides on the leading edge of the LMC, where ram pressure stripping, and the compression of the interstellar medium likely resulting from this, is at a maximum. At its core lies the extremely compact cluster of stars (~2.5 pc diameter) – R136a – that produces most of the energy that makes the nebula visible.

The closest supernova since the invention of the telescope, Supernova 1987A, occurred in the outskirts of the Tarantula Nebula.
As always, you can visit the remote telescope by clicking on the IYA “LIVE Remote Cam” Logo to your right. Just remember if you get an error message, that means it is either daylight or cloudy. We’ll be broadcasting whenever skies are clear and dark in Central Victoria! Enjoy…

I think I read somewhere that at the distance of the Orion Nebula, NGC 2070 would span over 30 degrees across the sky ! No wonder it would light up the nighttime landscape. What a stupendous star forming region. And the cluster R136a at its’ heart is an object unto itself. It sure is prominent in this video, even 180,000 light-years away!
