FRB 190520 is only the second example of a repeating fast radio burst with a compact source of persistent radio emission between bursts. An artist’s conception of a neutron star with an ultra-strong magnetic field, called a magnetar, emitting radio waves (red). Image credit: Bill Saxton, NRAO / AUI / NSF. Fast radio bursts (FRBs) are mysterious and rarely detected bursts of radio waves from space. The first FRB was discovered in 2007, although it...

This Hubble image shows Ruprecht 106, a globular cluster some 69,100 light-years away in the constellation of Centaurus. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This diagram shows three layers of aerosols in the atmospheres of Uranus and Neptune. The height scale on the diagram represents the pressure above 10 bar. The deepest layer (Aerosol-1 layer) is thick and composed of a mixture of hydrogen sulfide ice and particles produced by the interaction of the planets’ atmospheres with sunlight. The key layer that affects the colors is the middle layer, which is a layer of haze particles (Aerosol-2 layer) that is thicker on Uranus than on Neptune. Irwin et al. suspect that, on both planets, methane ice condenses onto the particles in this layer, pulling the particles deeper into the atmosphere in a shower of methane snow. Because Neptune has a more active, turbulent atmosphere than Uranus does, the team believes Neptune’s atmosphere is more efficient at churning up methane particles into the haze layer and producing this snow. This removes more of the haze and keeps Neptune’s haze layer thinner than it is on Uranus, meaning the blue color of Neptune looks stronger. Above both of these layers is an extended layer of haze (Aerosol-3 layer) similar to the layer below it but more tenuous. On Neptune, large methane ice particles also form above this layer.
