Our Galaxy's Black Hole Recently Flared Crazily Bright, And We Still Don't Know Why
The supermassive black hole at the heart of the Milky Way, Sagittarius A*, is usually relatively quiet. It's not an active nucleus, spewing light and heat into the space around it; most of the time, the black hole's activity is low key, with minima

Reader question: I heard that carbon dioxide makes up 0.04 percent of the world's atmosphere. Not 0.4 percent or 4 percent, but 0.04 percent! How can it be so important in global warming if it's such a small percentage?

The Biggest Volcano on Io May Be About to Erupt, And Scientists Are Watching Closely
The biggest volcano on Jupiter's moon Io could be about to blow. Decades of observation have revealed a periodic cycle in the volcano's eruptions; according to past behaviour, it's due for the next one any day.
Artificial Intelligence Takes On Earthquake Prediction
After successfully predicting laboratory earthquakes, a team of geophysicists has applied a machine learning algorithm to quakes in the Pacific Northwest.
May of last year, after a 13-month slumber, the ground beneath Washington’s Puget Sound rumbled to life. The quake began more than 20 miles below the Olympic mountains and, over the course of a few weeks, drifted northwest, reaching Canada’s Vancouver Island. It then briefly reversed course, migrating back across the U.S. border before going silent again. All told, the monthlong earthquake likely released enough energy to register as a magnitude 6. By the time it was done, the southern tip of Vancouver Island had been thrust a centimeter or so closer to the Pacific Ocean.
Because the quake was so spread out in time and space, however, it’s likely that no one felt it. These kinds of phantom earthquakes, read about them here
