Behemoth sunspot AR3664 unleashed the largest solar flare ever, causing radio blackouts on Earth (video)

He went and did it again. Massive sunspot AR3664 has unleashed the most powerful solar flare ever, and Earth is once again in the line of fire. The X3.98 burst peaked early this morning (May 10) at 02:54 (0654 GMT) and triggered a temporary or complete loss of high-frequency (HF) radio signals across Asia, Eastern… Read More »

Severe geomagnetic storm alert issued for first time in 19 years

A severe G4 geomagnetic storm could emerge as early as Friday, prompting NOAA officials to trigger a storm of that magnitude for the first time in nearly 20 years. The hour comes after days of solar activity that sent several bursts of plasma and magnetic fields toward Earth. G4s are the second strongest form of… Read More »

Giant 15-Earth-wide sunspot explodes with another massive X-class solar flare (video)

AR3664 is no ordinary sunspot. The giant dark region on the Sun’s surface has ballooned in recent days, becoming one of the largest and most active regions. sunspots I saw it solar cycle. AR3664 came to the attention of scientists earlier this week when the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center… Read More »

The sun erupts with powerful solar flares caused by hyperactive sunspots (video)

AR3663, the most active sunspot of Solar Cycle 25, has done it once again! Another X-class solar flare is being launched as we approach SunThe western branch of . And this is not alone; sunspot ‘cousin’ AR3664 also released an X flare and several M-class solar flares. The pair of sunspots don’t look like they’re… Read More »

Next generation satellites will paint a clearer picture of a changing Earth

Thanks to the next generation of satellite systems implemented by scientists, such as the National Oceanic and Atmospheric Administration’s GOES-R series, scientists can obtain high-resolution images of the Earth faster than ever before. This is data that helps paint a complete picture of our planet; The satellites can be thought of as cooperating with each… Read More »

NOAA says the world’s coral reefs are being hit by the fourth mass bleaching event

Extreme ocean heat is causing a mass bleaching event in coral reefs worldwide, according to the National Oceanic and Atmospheric Administration. NOAA announced Monday that “4. global coral bleaching event” and that bleaching has been documented in every major ocean basin in the past 14 months, including off Florida in the United States, Australia’s Great… Read More »

Ocean heat is causing a global coral bleaching event, and it could be the worst event in history

A mass bleaching event is occurring in coral reefs around the world as the climate crisis triggers record-breaking ocean heat, two science organizations announced Monday. some experts warn this could be the worst bleaching period in recorded history. More than 54% of the world’s coral reef areas experienced bleaching last year, affecting at least 53… Read More »

NOAA says coral reefs are undergoing fourth global bleaching event

By Gloria Dickie and Alison Withers (Reuters) – Many of the world’s colorful coral reefs have turned a ghostly white along coastlines from Australia to Kenya to Mexico, scientists said on Monday, the fourth global bleaching event in the past three decades. At least 54 countries and territories have experienced mass bleaching of reefs since… Read More »
