Save the Earth: Hit asteroid with spaceship

It sounds like the plot of a bad Bruce Willis movie, but some experts are saying it should be a reality.

To the moon? Firm hopes to sell $1.5 billion trips


Attention wealthy nations and billionaires: A team of former NASA executives will fly you to the moon in an out-of-this-world commercial venture combining the wizardry of Apollo and the marketing of Apple. For a mere $1.5 billion, the business is offering countries the chance to send two people to the moon and back, either for research or national prestige. And if you are an individual with that kind of money to spare, you too can go the moon for a couple days.

As far back as the 1930s, astronomers watching distant galaxies saw that something was missing: There were not enough stars to account for the heavy gravity needed to whirl galaxies so quickly or smash them together so swiftly.

Dwarf planet Makemake laid bare

Astronomers have obtained an important first look at the dwarf planet Makemake - finding it has no atmosphere. One of five such dwarfs in our Solar System including former planet Pluto, Makemake had until now eluded study. But in April 2011, it passed between the Earth and a distant star, and astronomers used seven telescopes to study how the star's light was changed.


Astronomers spy a planet untethered to any star; there may be many more


There’s an orphan planet roaming our galactic neighborhood. It’s a globe of gas about the size of Jupiter, astronomers say. And it’s out there by its lonesome, untethered to any star, drifting about 100 light-years from Earth. (In astronomical terms, that’s close.)
