We know that dinosaurs laid eggs, but did they bury their nests as crocodiles do, or leave them open and exposed, like birds? New research has some answers.
Here are some awesome new images of views across Mars’ Gale Crater – now being explored by NASA’s Curiosity rover. In these black-and-white images, the rover is using its NavCams (Navigational Cameras), which obtain a wide-angle view of the terrain, but don’t shoot in color as the rover’s 34mm and 100mm MastCams do. Look inside for more images, which include selfies of the rover!
The idea of fine-grained streams of dark matter stems from theoretical calculations done in the 1990s. Now a JPL astronomer, Gary Prézeau, has carried the idea a step further by running computer simulations of what would happen if a dark matter stream encountered Earth or another planet. His work suggests that streams of dark matter – passing through Earth – would emerge as ultra-dense filaments or “hairs” and that there should be many dark matter hairs sprouting from Earth and the other planets in our solar system.
Blue Origin, a private spaceflight company founded by Amazon originator Jeff Bezos, says it has made a safe soft landing of its main rocket – called New Shepard – following a launch to sub-orbital space.

Including more women in international climate negotiations will lead to better results. Here are 15 climate champions already making a difference.
With COP21 poised to begin in Paris, a new UN report suggests that weather-related disasters were nearly twice as frequent over the past decade as two decades ago.
A lot of dark matter lies between us and these distant galaxies. Light distortion from gravitational lensing creates the “cat.”
Photographer Mike Taylor in Maine discusses the fact that – while observing the aurora, or northern lights, is a truly awe-inspiring and often breathtaking experience – the images that come out of modern day DSLR cameras may not match what you witness in real life, especially if you live below about 50 degrees N. latitude.
