The LADEE spacecraft is on its way to the moon. The rocket and its two-stage separation was visible at least from the Washington D.C. suburbs, and likely up and down the East Coast, given the clear skies.
Since West Nile Virus was first identified more than a decade ago, applying bug spray became a must for summer outings. But sprays containing DEET can be a turn off. They can be smelly and feel greasy.
There's a hole in the sun's corona. But don't worry — that happens from time to time.
"A coronal hole is just a big, dark blotch that we see on the sun in our images," says Dean Pesnell, project scientist for NASA's Solar Dynamics Observatory. "We can only see them from space, because when we look at them [through] a regular telescope, they don't appear."
Scientists have demonstrated the ability to scale-up an 'uncrackable' computer encryption system that utilizes quantum physics to ensure security.
The technique is based on information that is carried by photons, the basic particles of light. While it's been demonstrated on a small scale, the team headed by Andrew Shields and publishing in Nature says they've shown that up to 64 users can share a single photon detector, eliminating the need for each one to have such an (expensive) device.
