Tune in!!!
 
Astronomers at the Space Telescope Science Institute have devised a new technique that allows the +Hubble Space Telescope to more accurately measure distances to stars within our galaxy - up to 10 times farther than previously possible using a method known as parallax.

Parallax is the most reliable method for directly measuring distances to stars within our galaxy. It uses the geometry of the Earth's orbit around the Sun to see tiny, almost imperceptible shifts of background stars behind the object being measured.

Previously this technique was only effective for distances up to 750 light years. Anything further away and we couldn't see the background stars shift; the change was too small.

This new capability allows astronomers using the Hubble Space Telescope to measure parallax distances up to 7,500 light years away - an astonishing increase in precision of a factor of 10!

Please join us as +Tony Darnell and +Scott Lewis discuss this new technique with Dr. Adam Riess, winner of the 2011 Nobel Prize in Physics and Dr. Stefano Casertano, the developers of this new ability for #Hubble .
This Hangout On Air is hosted by Scott Lewis. The live video broadcast will begin soon.

Big thumbs up :) Nice work Scott and Tony!
 
*Kepler's New Universe*

As promised, +Tony Darnell and I released our newest video on our YouTube channel, +Deep Astronomy. I'm very very happy with how it came out and have been excited to share it with you all!

It's called "Kepler's New Universe" and delves into the world of extrasolar planets, where the Kepler Space Telescope has opened up a completely different Universe than we knew existed before. 

About 20 years ago, we had no evidence for planets existing around any other stars besides our Sun, but now we know that our galaxy is bubbling over with them. I'm not exaggerating with that either, every star in our galaxy has, on average, 1.6 planets orbiting. 

Enjoy.

That was a pretty epic fight -- looking forward to the next one :)

"I think this is exactly the mainstream space science show that television has been waiting for since the original Cosmos aired over three decades ago. It links the humanity behind our urge to explore. It separates myth and religion from the scientific method, defining what the Cosmos means to us and how bright a future of discovery can be. But above all, Tyson, like Sagan did in the original series, shares his deep passion for science, enthusing the viewer to learn more and question everything."

You're right, it's not the only great show in the past 30 years, not by a long shot. I should have clarified that. I think this is the best space show of its category, driven by a personality that connects real science in a very general way. There have been many outstanding shows that dig a little deeper and I've been spoiled by documentaries such as Horizon (in the UK) my whole life. I just think the Cosmos reboot will have a large general appeal and the content will hopefully inspire youngster and adults alike who don't necessarily have a broad understanding of the topic.
