More than 400 years after Galileo’s first telescopic observations, we’re more certain than ever that the Earth is moving through space. How do we know? “Nature is relentless and unchangeable, and […]
This image is an extremely unique solar eclipse, taken from space and revealing the Moon’s shadow on the Earth’s surface.
How the mis-application of the Anthropic Principle has led factions of scientists away from the search for a natural, physical explanation of our Universe, and why that’s bad for everyone. […]
The plan would allow the world’s space agencies to share information about potentially dangerous asteroids, create a special task group to detect smaller asteroids, and collaborate on ideas for diverting them from Earth.
Should scientists advocate on policy issues, or, to protect their personal credibility and the credibility of their findings, should they just quietly do their work and avoid making policy […]
You never would’ve guessed that nuclear physics could be this easy. “Mr. Burns: Smithers, hand me that ice-cream scoop.Smithers: Ice-cream scoop?Mr. Burns: Damn it, Smithers! This isn’t rocket science, it’s brain […]
The most striking thing you will notice is the peanut shape of the central bulge of the galaxy, as viewed from a different perspective than we get from Earth.
First launched in 2009, the Wide-field Infrared Survey Explorer (WISE) spacecraft has been asleep in polar orbit for two years. Next month, it’ll be turned back on to help locate potentially dangerous near-Earth objects.
NASA’s Cassini orbiter has spent 8 years taking pictures of Saturn’s rings and moons, resulting in 200,000 pictures, and this wonderful video montage below.
Is running up an inclined treadmill the same, physically, as running up an actual mountain? Here’s what science has to say. “Nothing worth having was ever achieved without effort.” -Teddy Roosevelt […]
Rather than the six or seven you may have learned, your eye is capable of delineating a tremendous number more. But just how many, and what’s the explanation? “The colors […]
The massive storm that wrapped itself around the planet in 2010-2011 seems to have dredged up water ice from an invisible lower atmospheric layer, according to NASA researchers.

As part of this week’s Festival of the Planets celebration, University College London has made available to the public a selection of historic images from its archive. Included are glimpses of the surface of Venus.
This video animation gives us a tantalizing glimpse into one proposed method for asteroid retrieval, which would serve as a stepping stone for future missions to asteroids.
Due to the popularity of SmallSats, industry and government agencies have come aboard the SmallSat bus. However this attention has shed light on a major obstacle: the challenge of getting those SmallSats to space in a responsive and cost-effective manner.
At NASA the waste management engineers are incredibly important to the entire mission, says Mary Roach.
