Radiologically contaminated sites such as the Chernobyl Exclusion Zone have created novel environmental stressors with the potential to substantially influence the ecology of organisms and wider ecosystem function. Nevertheless, radiation dose rates at which negative effects occur are uncertain. Burrows et al investigated a potential mechanism for these sub-lethal consequences by testing whether radiation exposure makes bees less metabolically efficient. Image credit: Josef Pichler.

Magnetic fields in the spiral galaxy Messier 77, also known as M77 and NGC 1086, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the NASA/ESA Hubble Space Telescope, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms of Messier 77, implying that the gravitational forces that created the galaxy’s shape are also compressing the its magnetic field. This supports the leading theory of how the spiral arms are forced into their iconic shape known as ‘density wave theory.’ SOFIA studied the galaxy using far-infrared light (89 microns) to reveal facets of its magnetic fields that previous observations using visible and radio telescopes could not detect.

Schematic diagram of orbit determination model output for the 19 January 2019 particle ejection event from Bennu observed by the OSIRIS-REx spacecraft: Bennu is depicted in gray and has a diameter of 1,640 feet (500 m). OSIRIS-REx is indicated with the brown dot, 1.2 miles (2 km) from Bennu’s center of mass; the cone represents the viewing angle; blue arcs are particle trajectories, ending or with gaps where the trajectories pass into shadow; the Sun-angular momentum frame coordinates are shown at bottom right: x - solar vector, y - Bennu orbital direction, z - Bennu north.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.
