5+ mon, 6+ day ago   (179+ words) lead image In the case of Earth’s bow shocks, Ruolin Wang and Takanobu Amano hypothesize that whistler waves — low-frequency electromagnetic waves — are involved in electron acceleration and confinement. The duo modeled the electron velocity distribution function of reflected electrons at…...

5+ mon, 2+ week ago   (166+ words) NASA's Juno spacecraft passed north-to-south (yellow track) over Jupiter's atmosphere on 17 August 2022, detecting a cluster of radio pulses from lightning (cyan symbols marking instrument pointing for each pulse). Background map from the Hubble Space Telescope identified the lightning source as…...

9+ mon, 3+ week ago   (334+ words) New study shows how a major space storm dramatically shrank Earth’s protective plasma layer and slowed its recovery, helping improve solar storm forecasts and protect space infrastructure we rely on. image: Scientists have captured the first detailed observations of how…...

9+ mon, 3+ week ago   (533+ words) In May 2024, Earth was hit by the strongest geomagnetic storm in more than 20 years. Known as the Gannon storm or the “Mother’s Day storm,” it was triggered by a series of massive solar eruptions that sent huge clouds of charged…...

9+ mon, 4+ week ago   (525+ words) The Sun has spent the past few days hurling repeated bursts of energy and plasma toward Earth, unleashing a sequence of geomagnetic storms that lit up skies across continents and sent satellites and power grids into a state of high…...

10+ mon, 18+ hour ago   (198+ words) A massive X5.1-rated solar flare — the strongest in over a year — has been causing a severe geomagnetic storm in North America and around the world. That's set to continue on Wednesday, Nov. 12, but the solar flare also caused something that's…...

10+ mon, 1+ day ago   (320+ words) In a striking display of solar fury, a recent burst of high-energy particles from the Sun has created what scientists are calling a “hailstorm in space.” The phenomenon was dramatically captured by the SOHO (Solar and Heliospheric Observatory) spacecraft. In…...

11+ mon, 1+ day ago   (33+ words) A new University of Michigan study offers one of the most detailed pictures so far of how violent sun storms spread across space — and occasionally, straight to our planet. With the help of......

10+ mon, 2+ week ago   (395+ words) Our Sun seems pretty calm these days with a largely stable regular solar cycle revealed by sunspots and flare activity but billions of years ago, it was quite simply a menace. Scientists have just captured evidence of what the Sun…...

10+ mon, 4+ week ago   (307+ words) New simulations have uncovered twisting magnetic “solar tornadoes” forming between the Sun and Earth. This reveals a hidden cause of geomagnetic storms that can disrupt satellites, power networks and communications even without a direct solar blast. A fresh set of…...
