“Based on rough estimates, it’s about 150,000 metric tons of water ice, the equivalent of 60 Olympic swimming pools,” he said. The volcanoes are near the Mars equator, the warmest area of the planet, which makes a water discovery particularly intriguing, Valantinas said. “Mars is a desert planet, but there’s water ice in the polar caps, and there’s water ice in the midlatitudes. Now we also have water frost in the equatorial regions, and equatorial regions are quite dry in general. “If the frost on these volcanoes is confirmed to be water (and not carbon dioxide), it would be surprising,” he said.

CNN —Astronomers have discovered three previously unknown moons around Uranus and Neptune, the most distant planets in our solar system. In the future, the tiny satellite will be named after a Shakespearean character, in keeping with the tradition of Uranus’ moons bearing literary names. He worked with Marina Brozovic and Bob Jacobson of NASA’s Jet Propulsion Laboratory in Pasadena, California, to determine the moon’s orbit. The outer moons orbiting all the giant planets across our solar system — Jupiter, Saturn, Uranus and Neptune — share similar configurations. “Even Uranus, which is tipped on its side, has a similar moon population to the other giant planets orbiting our Sun,” Sheppard said.

NASA's Juno spacecraft snapped detailed images of the most volcanically active world in our solar system on Saturday. During this close fly-by, the spacecraft spotted plumes of volcanic activity erupting from Io's surface in real-time. This encounter was the second in a set of two close fly-bys designed to provide new insight into the fiery phenomena that lurk beneath Io's surface. The twin flybys are designed to provide new insight into how Io’s volcanic engine works and whether a global magma ocean exists under Io’s rocky surface.

Energy Secretary Jennifer Granholm, Deputy Defense Secretary Kathleen Hicks and Brenda Mallory, chair of the White House Council on Environmental Quality, announced the projects Wednesday at the Pentagon. Because of the Pentagon's “relatively congested air space” outside Washington, solar panels were the best option for clean energy, he said. The building is a nationally registered historic landmark, so officials will work with local officials to ensure the panels meet all requirements. In addition to the Defense Department, projects also include installation of thermally efficient windows at the Energy Department headquarters in Washington, as well as efficiency upgrades to the Commerce and Transportation departments. The projects also include installation of solar panels at the U.S. Army Garrison in Wiesbaden, Germany, as well as energy and water efficiency improvements and solar panels at the Maui Air Traffic Control Tower in Kahului, Hawaii.

At 1,600 meters (5,249 feet) tall, it’s nearly twice the height of Dubai’s Burj Khalifa, the tallest building in the world, according to a news release from Schmidt Ocean Institute, a nonprofit organization that advances oceanographic research. The ship is designed to map the seafloor by using a multibeam echosounder, which sends out sound waves to the ocean floor in a fan-shaped pattern, then measures the time it takes for the sound to reach the ocean floor and return. Schmidt Ocean InstituteThe seamount was discovered 84 nautical miles outside the Guatemalan Exclusive Economic Zone. Watling was not involved with the discovery but was part of a Schmidt Ocean Institute exploration in 2019. The recently discovered seamount may be taller than the world’s tallest building, but some have been found to have a height of 4,000 meters (13,123 feet) or more, Watling said.

Those winds also battered power lines on the island, and dramatic videos show lines swaying and being toppled in the gusts. Now, some locals are casting blame on Hawaiian Electric, the state’s biggest utility, for not shutting off power to high-risk areas – and claiming that its power lines could have sparked the deadly fire. State officials were well aware of the danger posed by downed power lines during hurricanes. A 2021 state report noted that “downed power lines” and “residential and wildland fires” were hazards related to hurricanes. Maui Mayor Richard Bissen said Thursday that power lines that were “still energized” had fallen on the roads.

CNN —A Jupiter-like planet located 520 light-years from Earth may be an unlikely survivor after its host star had a temper tantrum. The gas planet is known as 8 UMi b and was named Halla after its initial discovery by Korean astronomers in 2015. The exoplanet orbits a giant star larger than our sun named Baekdu, located in the Ursa Minor, or “Little Bear,” constellation. Halla orbits Baekdu at a distance about half that between the Earth and the sun at 0.46 astronomical units, or 42,759,659 miles (68,815,020 kilometers). While our solar system only has one star, many stars across the universe exist in binary pairs.

Measurements are taken in May because it is the month when CO2 peaks in the Northern Hemisphere. The outpost on Mauna Loa has measured atmospheric CO2 since 1958, when the level was less than 320 ppm, and shown a steady increase since then in what NOAA Administrator Rick Spinrad called "a direct result of human activity." NOAA began collaborating with Scripps on the measurements in 1974. This year's measurements were taken from a temporary site because lava flows cut off access to the Mauna Loa observatory in November 2022, NOAA said. (This story has been corrected to change NOAA's previously reported figure as 424 ppm and not 423 ppm, in paragraph 2.

Kilauea, one of the world’s most active volcanoes, began erupting again in Hawaii on Thursday, nearly a month after federal officials said activity there had ceased. The U.S. Geological Survey said webcam images showed lava flow within the Halemaʻumaʻu crater in the volcano's summit caldera. Hawaii’s Kilauea volcano, looking east from the west rim of the summit caldera, on Thursday in a webcam image provided by the U.S. Geological Survey. U.S. Geological Survey via APThe volcano, in Volcanoes National Park on Hawaii’s Big Island, has been erupting often since 1983. In November, another eruption on Hawaii's Big Island — from Mauna Loa, the world's largest active volcano — came after a series of large earthquakes.

[1/4] A rising lava lake is seen within Halema'uma'u crater during the eruption of Kilauea volcano in Hawaii, U.S. January 5, 2023, in this still image provided by the USGS surveillance camera. The volcano alert level was raised to 'Red' after an evaluation of the eruption and associated hazards, the notice said. USGS said the volcanic gas, which consists of sulphur dioxide and other gases, could produce a visible haze of volcanic smog, known as 'vog', which has been observed in the downwind of Kilauea. Known to be the younger and more active neighbor of Mauna Loa, which erupted in November for the first time since 1984, the Kilauea volcano has been erupting since 2021. However, Mauna Loa's eruption has had no impact and remains quiet, USGS said.

☆ Scientists declare Mauna Loa and Kilauea are 'no longer erupting'

HONOLULU — U.S. scientists declared Tuesday that two active Hawaii volcanoes — one where lava destroyed hundreds of homes in 2018 and another where lava recently stalled before reaching a crucial Big Island highway — have stopped erupting. “Kilauea is no longer erupting,” the U.S. Geological Survey’s Hawaiian Volcano Observatory said in a statement Tuesday, followed by a separate one saying, “Mauna Loa is no longer erupting.”Alert levels for both volcanoes were reduced from watch to advisory. Mauna Loa began spewing molten rock Nov. 27 after being quiet for 38 years, drawing onlookers to take in the incandescent spectacle, and setting some nerves on edge early on among people who’ve lived through destructive eruptions. Lava-viewers in Hawaii Volcanoes National Park enjoyed the added rare marvel of being able to see Mauna Loa’s smaller neighbor, Kilauea, erupting at the same time. Mauna Loa lava didn’t pose a threat to any communities, but it got within 1.7 miles of a major highway that connects the east and west sides of the island.

Officials downgraded the alert level for Hawaii's Mauna Loa volcano from a warning to a watch on Saturday as they predict that the eruption of the world's largest active volcano could soon end. "High eruption rates will not resume based on past eruptive behavior and current behavior suggests that the eruption may end soon," the U.S. Geological Survey said in a bulletin issued Saturday. The new alert level reflects "the limited hazards associated with the current activity," the latest update states. Its eruption began Nov. 27, marking its first eruption since 1984 and prompting warnings from officials that residents stay alert. Before the most recent eruption, geologists had recorded 33 eruptions since 1843, making Mauna Loa among the world’s most active volcanoes.

Dec 10 (Reuters) - Lava and volcanic gas emissions at Hawaii's Mauna Loa, the world's largest active volcano, declined on Saturday, the U.S. Geological Survey's (USGS) Hawaiian Volcano Observatory said. As a result, the Observatory downgraded the alert level for the volcano to a watch from the previous level of warning, with lava confined to a small area. Under a watch alert level, an eruption is underway but poses limited hazards. Mauna Loa began erupting in late November for the first time since 1984, ending its longest quiet period in recorded history. The behavior of the volcano suggests the eruption may end soon.

REUTERS/Go NakamuraDec 2 (Reuters) - The lava flowing from Hawaii's Mauna Loa, which is the world's largest active volcano and erupted this week, is edging closer to the Big Island's main highway. But the USGS also said that because of the unpredictable nature of lava flows, it's "difficult to estimate when or if the flow will impact" the highway, which is the island's main east- west road. On flatter ground, lava flows spread out and "inflate" - creating individual lobes that can advance quickly and then stall. Mauna Loa rises 13,679 feet (4,169 meters) above the Pacific Ocean, part of a chain of volcanoes that formed the islands of Hawaii.
