Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds’ deep oceans.

Non-erupting volcanoes leak a surprisingly high amount of sulfur-containing gases. A Greenland ice core shows that volcanoes quietly release at least three times as much sulfur into the Arctic atmosphere than estimated by current climate models. Aerosols are the most uncertain aspect of current climate models, so better estimates could improve the accuracy of long-term projections.

Something is amiss in the Butterfly Nebula. When astronomers compared images from 2009 & 2020, they saw dramatic changes in its "wings." Powerful winds are driving complex alterations of nebular material. It's unknown how such activity is possible in what should be a “largely moribund star with no remaining fuel.”

Astronomers discovered that the star Gaia17bpp gradually brightened over a 2 1/2-year period. But follow-up analyses revealed that the star itself wasn’t changing. Instead, it's likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, "dusty" stellar companion.

Save the ... parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn -- and that means not just fewer worms, but losses for the entire ecosystem.

A new study reports that college students in Seattle fall asleep later and wake up later in winter, likely because -- as the study also found -- in winter the students received less daylight exposure.

The Virtual Field Geology project has many goals: to make geology field experiences accessible to more people; to document geological field sites that may be at risk from erosion or development, to offer virtual “dry run” experiences and to allow scientific collaborators to do virtual visits to a field site together. While the pandemic brought new urgency to the project, its developers believe it’s part of a “new normal” for geology research and education.

The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington-led study reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea.
