In a recent study, scientists using the NASA/European Space Agency Hubble Space Telescope detected ozone in Earth's atmosphere during a lunar eclipse on Jan. 20-21, 2019. But they did so indirectly, capturing light that bounced off the moon after passing through Earth's atmosphere.

On this date in Maine history: Aug. 7 - Portland Press Herald
Aug. 7, 1823: Maine's first recorded meteorite falls between 4 and 5 p.m. in Nobleboro, startling a nearby flock of sheep when it hits the ground.
Mr. A. Dinsmore, who looks for the rock after hearing what he later says sounded like musket fire, digs down about 6 inches and recovers 5 or 6 pounds of a mass that smells like sulfur. The fallen object – only the second reported in the United States – proves to be achondrite, a type representing only 3 percent of all recovered meteorites. Samples of it are now in museum collections around the world.

UC Berkeley sleep researcher Matthew Walker, author of the international bestseller, Why We Sleep, and numerous breakthrough studies that explore what happens to the brain as we slumber, has won the 2020 Carl Sagan Prize for Science Popularization.
"I am humbled, not to mention utterly surprised, at receiving the Carl Sagan Prize. Carl Sagan has remained one of my true scientific heroes and inspiration, especially in regard to the public communication of science," Walker said.

Volcanic Eruptions, Not Meteors, Were Responsible For the Earth’s Cooling 13,000 Years Ago
Some researchers believed the event – which cooled the Earth by about 3 degrees Centigrade, a huge amount – was caused by an extraterrestrial impact with the Earth, such as a meteor collision. But the current study, published in the journal Science Advances, shows the evidence left in layers of sediment in Hall’s Cave was almost certainly the result of volcanic eruptions.
According to the research team, Hall’s Cave, located in the Texas hill country, has a sediment record extending over 20,000 years and they first began researching the cave in 2017.
How space missions snatch pieces of other worlds and bring them back to Earth

They will join a priceless collection of cosmic material brought back from other planetary bodies throughout the space age. From lunar rocks gathered by the Apollo astronauts to shards of a distant asteroid collected by robot spacecraft, these samples of other worlds have reshaped scientific study of the Solar System.
