Before we run through the news of the day, let's pause for something spectactular: a new video from NASA's Solar Dynamics Observatory. It shows a "massive filament" eruption on the sun that occurred last Friday. As Britain's The Register says, it is "mind-bogglingly gorgeous."
"In one study, astronomers used WISE to identify about 2.5 million actively feeding supermassive black holes across the full sky, stretching back to distances more than 10 billion light-years away. About two-thirds of these objects never had been detected before because dust blocks their visible light. WISE easily sees these monsters because their powerful, accreting black holes warm the dust, causing it to glow in infrared light."
This week, Americans have been remembering Neil Armstrong. But before he walked on the moon, he had to solve a much more prosaic problem.
"You're about to embark on a mission that's more dangerous than anything any human has ever done before," Robert Pearlman, a space historian and collector with collectspace.com, told me.
