Mars is usually considered a geologically dead planet, but a new study challenges that idea. Multiple lines of evidence reveals a giant plume of magma is forcing its way up through the Red Planet’s mantle and producing seismic activity in one particular region of the surface.After a volcanically active youth, Mars seems to have calmed down in middle age. But apparently it still knows how to party sometimes – NASA’s InSight lander has detected as many as 1,300 “marsquakes” in its four years of operation. Most of these seem…

Artist’s impression of an active mantle plume – a large blob of warm and buoyant rock – rising from deep inside Mars and pushing up Elysium Planitia, a plain within the planet’s northern lowlands. Volcanism at Elysium Planitia originates from the Cerberus Fossae, highlighted in red, a set of young fissures that stretches for more than 800 miles across the Martian surface. Recently, NASA’s InSight lander found that nearly all Martian quakes, or marsquakes, emanate from this one region. Credit: Adrien Broquet & Audrey…

A spectacular and explosive volcanic eruption in January 2022 produced the highest plume of steam and ash in recorded history.The towering column that arose from Hunga Tonga-Hunga Ha'apai reached a tremendous altitude of 57 kilometers (35 miles) above sea level.That height makes it the first-ever volcanic eruption seen to have punched completely through the stratosphere to breach the mesosphere."It's an extraordinary result as we have never seen a cloud of any type this tall before," says atmospheric scientist Simon…

Gif: Simeon Schmauß / Japan Meteorological Agency / Korea Meteorological Administration / National Oceanographic and Atmospheric AdministrationVolcanic eruptions can create serious impacts on human activity and climatic behavior, as ash, gases, and water are lofted high into the sky. While most eruptions are relatively shallow in the atmosphere, the plume generated by the incredibly powerful January 2022…

New analysis of a volcanic eruption off the coast of Tonga earlier this year has revealed the true extent of the massive explosion, and established its plume as the highest on record. It is also the first one to be seen stretching through lower layers of the atmosphere to enter the mesosphere, which begins at an altitude of some 50 km (31 miles).The eruption of the Hunga-Tonga Hunga-Ha'apai to the north of Tonga on January 14 is regarded as one of the most powerful ever observed, with the event causing devastating…

An astrophotographer has captured a hauntingly beautiful image of a massive plume of plasma shooting out of the Sun.The fiery filament, known as a coronal mass ejection (CME), extended into space to a distance of more than 1 million miles (1.6 million kilometers) from the solar surface, according to the photographer.The image was captured Sept. 24 by professional astrophotographer and Arizona resident Andrew McCarthy, and he shared the stunning view on Reddit on Sept. 25 in the subreddit r/space.The CME was part of a…

The object at top is Dimorphos, while the object in the foreground is Didymos.Image: ASI/NASAThey’re raw and a bit grainy, but LICIACube’s first batch of images have arrived, showing the immediate effects of the DART spacecraft crashing into Dimorphos. The 31-pound (14-kilogram) LICIACube (pronounced LEE-cha-cube) was trailing behind DART at the time of impact, having been dispatched by the NASA spacecraft two weeks ago. The probe has two optical cameras, LUKE and…
