NASA Balloon Detects California Earthquake - Next Stop, Venus?
NASA
Four "heliotrope" baloons were flown near Ridgecrest, California, after a series of earthquakes rattled the region in 2019. By attaching barometers to the balloons, researchers from JPL and Caltech hoped to detect the sound of one of the aftershocks. Image by NASA/JPL/Caltech.

Recent Legislation Would Reduce the U.S. Strategic Petroleum Reserve
Energy Information Administration
The United States used about 18.19 million barrels of crude oil per day in 2020. So, 50 million barrels would be about 2.75 days of consumption at the 2020 rate. Pre-pandemic the crude oil consumption was about 13% higher.

At Kilauea, Hawaii: The Refilling of Halema'uma'u Crater
United States Geological Survey
The ongoing eruption at Kilauea summit continues to fill Halema'uma'u crater with lava. A gas plume rises from the active vent on the west (left) side of the crater as lava flows from the vent into the rising lava lake (black surface). An overflow onto the lowest visible down-dropped block on the east (right) of the lava lake occurred on November 15. Above the block with the overflow, the edge of the largest down-dropped block stretches from bottom- to center-right. USGS photo taken by N. Deligne on November 16.

Lapis Lazuli, Afghanistan's Historic Gem and Pigment
Geology.com
High-quality lapis lazuli from Afghanistan has been used as a mineral pigment for over 1,000 years. Bright blue pieces of lapis are trimmed of impurities and ground to a fine powder; the powder can then be mixed with oil or another vehicle for use as a paint.
Higher-grade pigments can be produced by washing the powder with mild acid to remove calcite and dolomite that dilute the blue color. What remains can be washed to remove pyrite and other impurities. When dried and ground to a fine powder the resulting pigment is known as "ultramarine".

Iron Meteorites: The Hearts of Long-Vanished Asteroids

A spectacular example of the Sikhote-Alin iron meteorite, which fell in eastern Russia in 1947. This large specimen weighs 11.1 kg / 24 1/2 lbs and is described as a complete individual, as opposed to shrapnel specimens which are angular as a result of explosive fragmentation in the atmosphere. The scale cube pictured is 1 cm in size. Note the sculptural shape and abundant regmaglypts (thumbprint-like indentations), caused when the surface melted during flight.

Redistribution of Ash from the 1912 Eruption of Novarupta
Alaska Volcano Observatory
Strong northwesterly winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes have picked up loose volcanic ash erupted during the 1912 Novarupta-Katmai eruption and carried it to the southeast toward Kodiak Island this morning starting about 9:15 AKST (1815 UTC). The National Weather Service has issued a SIGMET for this low-level event and suggests that the maximum cloud height is 7,000 ft above sea level.

Study Traces Ammonia Pollution in Africa
NASA Earth Observatory
Ammonia is naturally emitted by soils and vegetation fires, but most of it is added to the atmosphere by humans through agricultural activities such as fertilizer use and livestock ranching. When present in excess amounts in an ecosystem, ammonia can make soils more acidic and hinder plant growth. As an air pollutant, it can provoke heart- and lung-related illness.

They believe that this is the largest diamond ever found in North America. It surpasses the Foxfire, a 187.7-carat diamond, also found at Diavik in 2015, which is believed to be the previous largest diamond found in North America. (As of November, 2021, Rio Tinto PLC became 100% owner of Diavik). Image by Dominion Diamond Mines.

Contrary to popular belief, Yellowstone is not "overdue" for eruption. Yellowstone experiences thousands of earthquakes every year, but these are not a sign of the volcano getting ready to erupt. Despite its reputation, most eruptions from Yellowstone are lava flows, not massive explosions.

Cautions in Viewing Objects
Henry Baker, The Microscope Made Easy, Chapter 15, Page 62 (1743)
Henry Baker's 1743 warning about using a microscope applies even to the examination of suspected fossils from Mars.
Beware of determining and declaring your opinion suddenly on any object; for imagination often gets the start of judgment, and makes people believe they see things, which better observations will convince them could not possibly be seen; therefore assert nothing till after repeated experiments and examinations in all lights and in all positions.
When you employ the microscope, shake off all prejudice, nor harbor any favorite opinions; for, if you do, 'tis not unlikely fancy will betray you into error, and make you see what you wish to see.
Remember that truth alone is the matter that you are in search after; and if you have been mistaken, let not vanity seduce you to persist in your mistake.

Added Transnational Oil Pipeline Capacity Could Reduce Crude Oil Shipped by Rail
Energy Information Administration
Image caption by EIA: "The Enbridge Line 3 replacement pipeline, which delivers crude oil from Edmonton, Alberta, in Canada to Superior, Wisconsin, became fully operational on October 1, 2021, increasing the pipeline's capacity to 760,000 barrels per day. Before the replacement, Enbridge Line 3 had a capacity of about half that amount. Because the Line 3 replacement project increases the capacity to import crude oil by pipeline from Canada, this pipeline could reduce the need to ship crude oil from Canada by other modes, especially rail."
