The Solar Orbiter has captured its first coronial mass ejection (CME) from the Sun, as Australia’s Bureau of Meteorology pushes for better space-weather watching capabilities.
NASA and the European Space Agency launched the orbiter to observe the solar winds and solar cycle, and it has just sent back the first grainy images of the CME, when a big burst of magma erupted from the Sun’s surface. The resulting magnetic field can wreak havoc on Earth.

Timor-Leste is suffering an unprecedented humanitarian crisis, jointly caused by a recent cyclone and by the rapid spread of COVID-19. These events threaten the very health and well being of our population. The country faces rising poverty, food and water insecurity, income loss, reduced productivity, malnutrition, and disease. These impacts are expected to worsen in the very near future.
On April 4, Tropical Cyclone Seroja tore across the capital Dili and other parts of the country with winds in excess of 125 kilometers per hour. Flash floods and landslides ensued, the likes of which had not been seen in decades. With its passage, the cyclone inundated major parts of the capital and affected some 2,100 hectares of agricultural land. It smashed public infrastructure including the waterfront, roads and bridges; it destroyed thousands of homes. The cyclone took the lives of 41 citizens, displaced about 8,000 people and caused serious economic and health-related difficul
Cyclone Seroja Damages Towns in Western Australia with Strongest Winds in 50 Years April 14, 2021
PERTH, Australia (AP) – A destructive cyclone has damaged several towns on Australia’s western coast, shattering windows, snapping trees and knocking out power. There have been no reports of serious injuries.
Tropical Cyclone Seroja crossed the Western Australia state coast south of the tourist town of Kalbarri with winds gusting up to 170 kph (106 mph) shortly after dark Sunday, officials said Monday.
Around 70% of buildings in Kalbarri, a town of 1,400 people 580 kilometers (360 miles) north of the state capital Perth, had been damaged, Department of Fire and Emergency Services Commissioner Darren Klemm said.
On November 21, 2016 hospital emergency wards across Melbourne, Australia were suddenly overrun with patients with severe respiratory problems. Ten people died and thousands struggled to breathe for frighteningly long periods. The event was not a forerunner of a viral epidemic, but the worst case of a phenomenon known as “thunderstorm asthma”. Scientists have now revealed that the commonly believed explanation for these events is wrong, and that they are triggered by lightning, not rain.
South-eastern Australia appears to be the worst place in the world for thunderstorm asthma, but the US has had several rounds and CSIRO s Dr Kathryn Emmerson told IFLScience the UK has experienced some as well. It s likely they are happening more widely on a less severe level that doesn t attract the same attention as a single big event, but cumulatively causes far more harm. If one coincided with a viral outbreak like COVID-19 things could get far worse, making predicting them a priority.
