The brightest supernovae yet found
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.

Stardust to end its mission after twelve years
Stardust has ended its mission after twelve years and two comet flybys.
Ground controllers will command the spacecraft to fire up its four rocket thrusters one last time at 7 p.m. EDT (2300 GMT) today to use up its remaining fuel. Engineers plan to watch closely while the probe’s propellant tank ran dry to help future missions gauge their fuel reserves more precisely.
