NASA Determines Australian Meteor Crater is the Oldest Known

Erickson did it by searching for rocks that showed signs of being subjected to the shock and heat of a meteor strike. In particular, he gathered rock samples that contain two minerals: zircon and monazite. The minerals are crystals that contain uranium and lead, the ratio of which can be measured to determine the age of rock.

Tektite: An excellent example of an Indochinite tektite from Southeast Asia. Tektites are fragments of ejecta produced when a large extraterrestrial object strikes the Earth. The heat of the impact flash melts rock in the impact area and ejects it in the molten state. These molten masses solidify into a natural glass, a mineraloid, in flight and fall to Earth in the area around the impact. The impact that produced the tektites of the Indochina strewn field occurred about 800,000 years ago.
This 48.7-gram specimen is 48 mm x 35 mm x 21 mm in size. The shiny, glassy surface is natural, and similar in appearance to obsidian, which is a terrestrial igneous rock. Note the small crater-like features on the surface of this specimen, which are reminiscent of regmaglypts found on meteorites. Photograph by Leigh Anne DelRay, copyright Aerolite Meteorites.

Also note that the Marcellus Shale potential source rock does not extend as far into Ohio as the Utica.
Australian Dust on New Zealand*s Glaciers
January 7 | NASA
Carried by the wind, dust and ash particles from Australia have painted some glaciers on the South Island of New Zealand with a brown-orange tint.

The Strait of Hormuz Is the World*s Most Important Oil Transit Chokepoint
January 7 | Energy Information Administration
The Strait of Hormuz, located between Oman and Iran, connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. The Strait of Hormuz is the world's most important oil chokepoint because about 21% of global petroleum liquids consumption pass through the strait each day.

Aquatic Rover Goes for a Drive Under Antarctic Ice
January 6 | NASA
An underwater rover called BRUIE is being tested in Antarctica to look for life under the ice. Developed by engineers at NASA-JPL, the robotic submersible could one day explore ice-covered oceans on moons like Europa and Enceladus. BRUIE is pictured here in an arctic lake near Barrow, Alaska in 2015.

Life on Europa?
January 6 | Geology.com
Life on Europa: Water from a subsurface ocean on Jupiter*s moon, Europa, could reach the surface through seeps or erupt from hot water vents. This water would reveal the chemistry of the subsurface ocean and may contain microbes that live below. Artist's concept image by NASA / JPL.

Southern California Snow
January 6 | NASA Earth Observatory
A potent winter storm slammed Southern California on December 26, delivering heavy rain, snow, and even a tornado. The storm brought between 1 and 3.5 inches of rain to low-elevation areas. Several inches to several feet of snow fell on higher ground.
