A team of researchers from the Departments of Geosciences, Atmospheric Sciences, and Statistics at Innsbruck has reported a doubling in the number of detected lightning strikes in the high altitudes of the European Eastern Alps over the last 40 years.
NASA scientists have confirmed the presence of a polar cyclone at the north pole of Uranus. The data, gathered between 2015 and 2022 using the Very Large Array in New Mexico, revealed warmer and drier air circulating below the planet’s clouds, a key indicator of cyclonic activity. The findings were published in Geophysical Research Letters.
A study conducted by scientists at Purdue University reveals that the Great Sitkin volcano, one of the most active in Alaska, has two magma chambers. This discovery explains the changing locations of seismic activity that has perplexed scientists since the volcano began erupting in May 2021.
A revolutionary research study from the University of Illinois Urbana-Champaign disputes the decades-old conventional understanding of the Earth’s continental plates. The study posits that the Earth’s ‘stable cratons’—previously thought to be immovable regions of continental plates—have experienced repeated deformations beneath their crust since their formation.
An international research team has unveiled a surprising discovery at the heart of the Milky Way galaxy. Under the leadership of Northwestern University’s Farhad Yusef-Zadeh, the scientists discovered a new type of filament near Sagittarius A*, our galaxy’s central supermassive black hole. This marks a significant departure from the vertical filaments previously known to science.
The Geminid meteor shower, one of the most spectacular yearly celestial events, was likely created by a sudden and violent occurrence, according to new findings by NASA’s Parker Solar Probe mission. These findings, published recently in The Planetary Science Journal, provide fresh insights into the origins of this meteor stream which, unlike most, emanates from an asteroid named 3200 Phaethon.
A new in-depth study reveals the potential eruption risk at Italy’s Campi Flegrei, also known as the ‘supervolcano’, has increased. The research, published on June 9, 2023, shows that the volcano has been showing signs of increased activity, raising both concerns and interest among scientists.
An international team of scientists revealed that the massive eruption of the underwater Hunga Tonga–Hunga Haʻapai volcano in Tonga on January 15, 2022, disrupted satellite signals across the globe. The team used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by the volcanic eruption could produce an equatorial plasma bubble in the ionosphere, severely affecting satellite-based communications.
Scientists from UiT, The Arctic University of Norway, in collaboration with REV Ocean, discovered a unique new volcano in the Barents Sea. The Borealis Mud Volcano, located at a depth of 400 m (1 312 feet) and approximately 130 km (80 miles) south of Bear Island, continuously emits mud, fluids and gas, providing valuable insights into Earth science.
A team of oceanographers has mapped 19 000 previously unknown undersea volcanoes using radar satellite data, which could improve ocean current modeling and submarine navigation.
