The latest Carnival of Space is now available at the Space Disco site, where Dave Mosher has put together a helpful slideshow of entries handsomely illustrated and linked to the originals. With seven new blogs coming online at Discovery Space...
Photons streaming outward from the Sun can impart momentum, which is how a solar sail works. But even more subtle effects produced by the warming of irregular objects may have visible results. A new study of asteroid moons and how the...
We usually picture the far future in terms of the most exotic possibilities. And why not: Getting to the stars with warp drive or wormhole makes the entire galaxy accessible.
Solar sail development has surely been a frustrating thing for Sandy Montgomery, who knows that what stands in the way of pushing this technology into space isn't the need for scientific breakthroughs but adequate funding.
The Earth receives thousands of tons of interplanetary dust every year as it makes its way around the Sun. Can we trace any of this material to a particular source? Scientists from the Carnegie Institution think the answer is yes, at least in the case...
If you’re going to snare dark matter, you’d better have incredibly accurate detectors. So the thinking goes at Case Western Reserve, where researchers are planning the most sensitive experiment yet to go after WIMPs (weakly interacting massive...
