The brightest supernovae yet found.
Supernova 2008am is 3.7 billion light-years away. At its peak luminosity, it was over 100 billion times brighter than the Sun. It emitted enough energy in one second to satisfy the power needs of the United States for one million times longer than the universe has existed.
“Worldwide-temperature increase has not produced acceleration of global sea level over the past 100 years”
From Watts Up With That: New sea level data shows that there has been “no acceleration of global sea level over the past 100 years,” despite the increase in temperatures. Key quote from the paper:
It is essential that investigations continue to address why this worldwide-temperature increase has not produced acceleration of global sea level over the past 100 years, and indeed why global sea level has possibly decelerated for at least the last 80 years.
