Look Out: Huge Asteroid to Pass Earth on May 31
The good news is that the asteroid, which was discovered 15 years ago, will get "no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon," according to NASA.
This image shows the orbit of asteroid 1998 QE2 which will be making a flyby on May 31 at 1:59 p.m. Pacific (4:59 p.m. Eastern / 20:59 UTC). If the 1.7 mile space rock were to make impact, we would almost certainly be doomed. The good news is that the asteroid, which was discovered 15 years ago, will get "no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon," according to NASA.

A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
