Study reveals key discovery about aurora activity on Jupiter

A team of international researchers has made a major discovery about aurora activity on Jupiter. Their study supports the previously controversial idea that Jupiter's polar cap is threaded in part with closed magnetic field lines and proves the lights hold clues...

Study reveals anomaly in pre-seismic atmospheric radon associated with inland earthquakes

Previous studies have shown elevated levels of radon in the atmosphere prior to the mainshock of a huge inland earthquake. However, in a new study, researchers revealed an anomaly in this phenomenon as they found that the concentration of the radioactive element...

Enormous chunks of alien planet Theia are buried beneath the Earth, research suggests

Scientists believe that around 4.5 billion years ago, a protoplanet called Theia collided with the Earth, sending debris into space that eventually formed the Moon. According to new research, the crash also likely left enormous chunks-- even millions of times larger...

Study shows correlation between solar variability and El Nino-La Nina events

A new study shows a link between the end of solar cycles and a switch from El Nino to La Nina events in the Pacific Ocean, indicating that solar variability can trigger seasonal weather variability on Earth. If the connection holds up, it could improve the...

NOAA study takes step closer to predicting meteotsunamis

A new study by NOAA shows the promise of forecasting meteotsunamis after scientists were able to reconstruct the first documented meteotsunami in the Great Lakes in 2018. On April 13, 2018, a huge wave surged across Lake Michigan, flooding the shores of Ludington...

Large meteoritic event over Antarctica 430 000 years ago

An international team of scientists has found new evidence that a low-altitude meteoritic event occurred over Antarctica 430 000 years ago. Cosmic particles recovered on the summit of Walnumfjellet indicate that an unusual touchdown event reached the continent's...

New model replaces dark energy theory with magnetic forces

It has been long believed that 70 percent of the universe is composed of dark energy, which makes it expand at an ever-increasing rate. However, a new model by researchers from the University of Copenhagen (UCPH) suggests that the expansion is due to a dark...

A tropical storm in 2018 produced the lowest temperature ever recorded on Earth

A tropical storm just south of the equator in the southwestern Pacific Ocean on December 29, 2018, produced an unprecedented temperature of -111.2 °C (161.96 K / -168.1 °F), the lowest recorded on Earth, according to a recent scientific research paper. The...

Hubble makes unexpected discovery on the process of star formation

New observations from the Hubble Space Telescope have changed our understanding of star formation as what scientists previously believed may have been an off-switch for the process does not work that way after all. The telescope shows that the powerful astrophysical...

Unexpected strike-slip earthquake uncovers hidden mechanism

Researchers uncovered the reason for unexpected strike-slip earthquakes, where two pieces of crust slide past each other on a fault, in areas where subduction zone tremors are common. From July to October 2020, a series of earthquakes occurred in Shumagin Islands,...

Research reveals unknown mechanisms that generate auroras

New research has revealed an unknown mechanism of the magnetosphere-- electrons from the Sun are propelled by electrical energy higher than previously thought, ultimately creating displays of northern and southern lights or auroras. The formation of auroras starts...
