Tonga volcanic eruption the most powerful in more than a century

Scientists have begun to piece together what happened during the January 15 eruption of the undersea Hunga Tonga-Hunga Ha’apai volcano about 65 kilometers (40 miles) north of Tonga’s capital that killed at least three people.

Astronomers in Germany have spotted a fiery ‘nova explosion’ from a white dwarf for the very first time. Researchers observed the event, thanks to data from the joint German-Russian eROSITA X-ray telescope, which is stationed in space about 900,000 miles away. The X-ray flash – dubbed YZ Reticuli – completely overexposed the center of eROSITA’s … Read more

Plants have been grown in lunar soil for the 1st time ever

But the experiments also reveal just how stressful it is for plants to grow in lunar regolith, or soil, which is wildly different from natural habitats on Earth. Different types of plants, including food crops, have flown on the space shuttle and the International Space Station. Plant samples have even been used to prove that … Read more

Mixed-up sunspot emits powerful solar flare

A mixed-up region of sunspots pointed almost directly at Earth has just emitted a major solar flare, which could cause havoc with power grids and communication networks over the next few days. NASA’s Solar Dynamic Observatory (SDO) first detected the sunspot area designated AR3006 (“AR” stands for “active region”) several days ago; now the region … Read more
