A rare “ring of fire” eclipse of the sun cuts across the Americas on Saturday, stretching from Oregon to Brazil.
For the small towns and cities along its narrow path, there was a mix of excitement, worries about the weather and concerns they'd be overwhelmed by visitors flocking to see the celestial event, also called an annular solar eclipse.
Unlike a total solar eclipse, the moon doesn’t completely cover the sun during a ring of fire eclipse. When the moon lines up between Earth and the sun, it leaves a bright, blazing border.
Saturday’s path: Oregon, Nevada, Utah, New Mexico and Texas in the US, with a sliver of California, Arizona and Colorado. Next: Mexico’s Yucatan Peninsula, Belize, Honduras, Nicaragua, Costa Rica, Panama, Colombia and Brazil. Much of the rest of the Western Hemisphere gets a partial eclipse.
Viewing all depends on clear skies — part of the US path could see clouds. NASA and other groups planned to livestream it.
With a chance of rain in its forecast, the small town of Reedsport near Oregon's Pacific Coast moved its eclipse festival inside so that a bounce house and games wouldn’t get soaked in the mud.
"But we’re still hoping that we might get a glimpse of it,” said city official Rosa Solano.
Weather was less of a concern in tiny Baker, Nevada, where the population hovers around 100. Inn and general store owner Liz Woolsey made T-shirts and planned a slate of activities including a drum circle and a dance party. Her seven rooms have been booked for over a year, The Associated Press reported.
“For a little place, we’re putting on a good show," said Woolsey, who became an eclipse enthusiast after seeing the 2017 total solar eclipse that swept the US from coast to coast.
Tens of thousands could get a double treat in Albuquerque, New Mexico. For the city's annual air balloon fiesta, which ends this weekend, hundreds of colorful hot air balloons lift off around dawn, hours before the eclipse briefly dims the skies.
Colombia’s Tatacoa desert was playing host to astronomers helping a group of visually impaired people experience the eclipse through raised maps and temperature changes as the moon blots out the sun.
At the Cancun Planetarium, young visitors built box projectors to indirectly and safely view the ring of fire. The ancient Maya — who called eclipses “broken sun” — may have used dark volcanic glass to protect their eyes, said archeologist Arturo Montero of Tepeyac University in Mexico City.
Towns and national parks in the path braced for a huge throngs. Officials in Oregon's Klamath County urged residents to stock up on groceries and fill their gas tanks in case traffic backs up on its two-lane highways. Utah's Bryce Canyon expected Saturday to be the park's busiest day of the year, spokesperson Peter Densmore said. Brazil's Pedra da Boca state park, known for its rocky outcrops for climbing and rappelling was also expecting crowds.
The entire eclipse — from the moment the moon starts to obscure the sun until it’s back to normal — is 2 1/2 to three hours at any given spot. The ring of fire portion lasts from three to five minutes, depending on location.
Next April, a total solar eclipse will crisscross the US in the opposite direction. That one will begin in Mexico and go from Texas to New England before ending in eastern Canada.
The next ring of fire eclipse is in October next year at the southernmost tip of South America. Antarctica gets one in 2026. It will be 2039 before another ring of fire is visible in the US, and Alaska will be the only state in its direct path.

A deep-diving robot that chiseled into the rocky Pacific seabed at a spot where two of the immense plates comprising Earth's outer shell meet has unearthed a previously unknown realm of animal life thriving underground near hydrothermal vents.

Giant tubeworms - the world's heftiest worms - and other marine invertebrates such as snails and bristle worms were found using the remotely operated underwater vehicle SuBastian. They were living inside cavities within the Earth's crust at an ocean-floor site where the Pacific is 1.56 miles (2,515 meters) deep. All the species were previously known to have lived near such vents, but never underground, Reuters reported.

"We discovered vent animal life in the cavities of the ocean's crust. We now know that the unique hydrothermal vent ecosystem extends into the ocean's crust," said marine biologist Sabine Gollner of the Royal Netherlands Institute for Sea Research, one of the leaders of the study published this week in the journal Nature Communications.

"To our knowledge, it is the first time that animal life has been discovered in the ocean crust," Gollner added.

The exploration was conducted at the East Pacific Rise, a volcanically active ridge on the floor of the southeastern Pacific, running approximately parallel to South America's west coast. Earth's rigid outer part is divided into colossal plates that move gradually over time in a process called plate tectonics. The East Pacific Rise is located where two such plates are gradually spreading apart.

This area contains many hydrothermal vents, fissures in the seafloor situated where seawater and magma beneath the Earth's crust come together. Magma refers to molten rock that is underground, while lava refers to molten rock that reaches the surface, including the seafloor. New seafloor forms in places where magma is forced upward toward the surface at a mid-ocean ridge and cools to form volcanic rock.

The hydrothermal vents spew into the cold sea the super-heated and chemical-rich water that nourishes microorganisms.

"The warm venting fluids are rich in energy - for example, sulfide - that can be used by microbes, which form the basis of the food-chain," Gollner said.

Life flourishes around the vents - including giant tubeworms reaching lengths of 10 feet (3 meters), mussels, crabs, shrimp, fish and other organisms beautifully adapted to this extreme environment. The giant tubeworms do not eat as other animals do. Instead, bacteria residing in their body in a sack-like organ turn sulfur from the water into energy for the animal.

The researchers deployed SuBastian from the Schmidt Ocean Institute research vessel Falkortoo to the vent site deep below. The robot was equipped with arms that wielded a chisel that the researchers used to dig into the crust and uncover warm and fluid-filled cavities where the tubeworms, bristle worms and snails were spotted.

"We used a chisel to break the rock. We dug about 20 cm (8 inches). The lava plates were about 10 cm (4 inches) thick. The cavities below the lava plates were about 10 cm in height," Gollner said.

Larvae from these animals may invade these subseafloor habitats, the researchers said, in an example of connectivity between the seafloor and underground ecosystems.

"It changed our view on connectedness in the ocean," Gollner said of discovering the subsurface lair.
