During the Bush administration, NASA began monitoring the Moon for explosions - they have turned out to be more common than previously believed, happening hundreds of times each year.  Smart…

Uranus and Neptune have a lot in common, climate-wise, even though Uranus is tipped on its side with the pole facing the sun during winter.  They are both home to extreme winds blowing at…

 4C+29.30, a galaxy located some 850 million light years from Earth, has a new composite image which shows how the intense gravity of a supermassive black hole can be tapped to generate immense…
