The United States Geological Survey has confirmed that a bright meteor that broke up over the Detroit area on the evening of January 16 caused a 2.0 magnitude earthquake in Michigan. The meteorite fell about five miles (8 kilometers) from the village of New Haven.

"After reviewing several observational datasets, the NWS can confirm the flash and boom was NOT thunder or lightning, but instead a likely meteor," tweeted the Detroit’s National Weather Service office, in response to social media activity regarding the 8:08 PM event. The USGS confirmation followed shortly after the NWS tweet.

New computer models of Mars’ atmosphere are indicating that the Red Planet may experience rapidly-falling snowstorms at night, possibly sprinkling the surface below with a light layer of snow. It was previously assumed that snow that fell on Mars did so slowly, taking hours to drop a single mile, and typically evaporating before it reached the surface. But the new simulations show that ice crystals forming at night may only take about five to ten minutes to fall the same distance, explaining why NASA’s Phoenix lander observed a dusting of snow shortly after touchdown in 2008.

Two new discoveries regarding chemical ingredients that are associated with the formation of life on Titan have been announced. With its dense nitrogen, methane and ethane atmosphere, and liquid hydrocarbon seas, Titan is currently of interest to scientists looking to study an environment resembling Earth’s primordial atmosphere, and also are hopeful that the Saturnian moon’s complex chemical soup will yield evidence of extraterrestrial life.

In science’s quest to develop less polluting sources of energy, hydrogen gas has often been used as an example as a potential replacement for fossil fuels: aside from being the most abundant substance in the universe, it is also the most combustible natural substance known, and only produces pure water when burned with oxygen. Unfortunately, the chemical instability of its gaseous form means that storing it is inherently hazardous, and the extraction of the gas from hydrogen’s more stable forms, such as water or petroleum products, can be highly energy inefficient, or produce a disproportionate amount of waste pollutants.
