Venus’ extraordinarily slow retrograde rotation was likely caused by a chance encounter with a moon-sized impactor. One that some 4.5 billion years ago likely slammed into our sister planet at a high angle and high velocity.

What happens to a comet as it leaves our inner Solar System?

Fossilized poo harbors remains from mammoths, bison and big cats, including some of the oldest DNA ever reconstructed

As Ebola rages, Moderna and others are racing to develop an mRNA vaccine for the rare Bundibugyo virus driving the current outbreak

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres.

NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published in Science Advances, examines this history by looking at the ratio of phosphorus to nitrogen in iron meteorites and in younger objects known as chondrites.
