Deep-sea brine pools are extraordinarily salty or "hypersaline" lakes that form on the seafloor. They are among the most extreme environments on Earth, yet despite their exotic chemistry and complete lack of oxygen, these rare pools teem with life and may offer insights on how life on Earth began — and how life could evolve and thrive on water-rich worlds other than our own.

Scientists say the lake's level is at a record low, largely because of a long-term drought across the American Southwest — but human-induced climate change may be making the drought worse.

Often, this shaking and juddering will come without much prior warning; even when the weather conditions appear calm, the plane may get shaken around to some extent, or could even briefly lose altitude before normal service is resumed. Such effects are sometimes attributed to a plane encountering an "air pocket," but is this accurate?

In a sprawling new status report posted to the pre-print database arXiv.org, NASA researchers have shared the first images showing the extent of that damage. Seen on the C3 mirror in the lower right-hand corner of the image, the impact site appears as a single bright white dent besmirching the golden mirror's surface.

The 11-ounce (320 grams) meteorite, officially dubbed Northwest Africa 7034 but commonly known as "Black Beauty," is believed to have smashed into Earth roughly 5 million years ago. After being found in the Sahara Desert in 2011, its age was dated to just under 4.5 billion years old — making it the oldest Martian meteorite ever found on Earth.
