Evidence blasted into space: Mystery why some meteorites look less shocked solved Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

Astronomers find Earth-like exoplanets common across the cosmos Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought. While it can be relatively easy to locate worlds that orbit close to their star, planets with wider paths can be difficult to detect. Still, researchers estimated that for every three stars, there should be at least one super-Earth present with a Jupiter-like orbital period, suggesting these massive worlds are extremely prevalent across the universe.

New framework suggests stars dissolve into neutrons to forge heavy elements Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all of physics. In the search for conditions suitable for these elements via "nucleosynthesis," a Los Alamos National Laboratory-led team is going where no researchers have gone before: the gamma-ray burst jet and surrounding cocoon emerging from collapsed stars.

Webb spots clues of a black hole at the heart of nearby galaxy M83 Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising finding, made possible by Webb's Mid-Infrared Instrument (MIRI), reveals highly ionized neon gas that could be a telltale signature of an active galactic nucleus (AGN), a growing black hole at the center of a galaxy.

Seeing the waves that make the sun's corona so hot If you happen to be enjoying a sunny day, thank the bright surface of the sun, known as the photosphere. At a piping hot temperature of about 5,800 K, the photosphere provides nearly all the sunlight Earth receives. But for all its glorious radiance, the photosphere isn't the hottest part of the sun. That award goes to the diffuse outer atmosphere of the sun known as the corona, which has a temperature of more than a million Kelvin. Parts of the corona can be as hot as 20 million Kelvin, which is hotter than the sun's core. Of course, the big mystery is why the corona is so hot.
