In this illustration, an exploding star powers jets of material. The star is shown as an almost flower-like shape. The purple �petals� represent clouds of material created in the explosion. The bluish-white and yellow center shows where the newly formed black hole begins driving the jets. The core of the jet pointed toward us is whitish and the broader regions are magenta. In the distance, on the far side of the star, you can see the opposite side of the jet disappearing into space.

Aerial view of recent lava flows near Mauna Loa’s summit in November 2022. The National Oceanic and Atmospheric Administration (NOAA) monitors greenhouse gases at Mauna Loa Observatory, which is 4 miles (6 kilometers) away from the summit crater. Despite the proximity, volcanic gases aren’t common at the observatory, and when they do happen, these temporary spikes are not included in the long-term data. The decades-long trend of increasing CO2 at Mauna Loa matches that from sampling sites all around the world. Credit: USGS/J. Schmith
