Let me ask you this: ‘Are bananas radioactive and is it true that eating too many can kill you?’

Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years. — Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once.

Comet Pan-STARRS Makes Stunning ‘Galactic Flyby'(VIDEO)

NASA 3D prints a model of light-year-long Eta Carinae nebula

A new shape model of the Homunculus Nebula reveals protrusions, trenches, holes and irregularities in its molecular hydrogen emission. The protrusions appear near a dust skirt seen at the nebula's center in visible light (inset) but not found in this study, so they constitute different structures.

MESSENGER and STEREO measurements open window into high-energy processes on the Sun

A solar flare erupted on the far side of the sun on June 4, 2011, and sent solar neutrons out into space. Solar neutrons don't make it to all the way to Earth, but NASA's MESSENGER, orbiting Mercury, found strong evidence for the neutrons, offering a new technique to study these giant explosions.
