Measuring vacuum energy of space?

Quoted: A different astronomy and space science related image is featured each day, along with a brief explanation.

Quoted: "It's a very intriguing object," says supernova researcher Stefan Immler of the NASA Goddard Space Flight Center in Maryland, US, but he will not rule out the possibility that it might be a supernova.

If it was extremely distant, the expansion of the Universe would relativistically stretch a supernova explosion. We would see a 20-day event stretched to 100 days at a red shift of 4, corresponding to an object about 12 billion light years away seen just 1.5 billion years after the big bang.

Reading this now. What a great story. I especially like how we can trace the measurement of the earth, to the distance to the moon, sun, stars, galaxy dimension, and finally galaxy distances.

Author of the Code Book! I've been really impressed with Mr. Singh's writing. The Code Book was amazing in it's ability to capture the breadth of historical cyrptography, as well as present detailed and technically accurate descriptions of the workings of many crypto systems (including Enigma) - all for a lay audience.

I have high hopes that his treatment of Cosmology will be similarly enlightning and accessible.
