NASA's Europa Clipper is tasked with up-close study of Jupiter's enigmatic moon Europa, which orbits the gas giant within a band of powerful radiation generated by the planet's strong magnetic field. The relative intensity of Jupiter's radiation bands is illustrated in this diagram, along with the orbits of Jupiter's three other largest moons: Io, Ganymede, and Callisto.

An artificially colored ultraviolet image of Jupiter reveals the Great Red Spot as a striking blue feature, while an oval of concentrated haze appears in the brown haze near the south pole. This dark oval, likely caused by mixing from a high-altitude vortex, mirrors similar but less frequent features seen at the planet's north pole.

WEAVE data overlaid on a James Webb Space Telescope image of Stephan's Quintet, with green contours showing radio data from the Low Frequency Array (LOFAR) radio telescope. The orange and blue colours follow the brightness of Hydrogen-alpha obtained with the WEAVE LIFU, which trace where the intergalactic gas is ionised. The hexagon denotes the approximate coverage of the new WEAVE observations of the system, which is 36 kpc wide (similar in size to our own galaxy, the Milky Way).

SwRI researchers are expanding corrosion modeling software to predict if icy worlds such as Saturn’s moon Enceladus may be able to harbor microbial life. In this cross-polarized light microscope image, pores are visible in glycine-doped ice formed in a laboratory investigation of Enceladus’ subsurface conditions. These pores could form habitable niches for microbial life.

Exploring Zero Gravity’s Impact on Heart Function in HFpEF Patients

This artist's illustration depicts the Large Magellanic Cloud (LMC) in the foreground as it passes through the gaseous halo of the much larger Milky Way galaxy. The encounter has stripped away much of the LMC's spherical gas halo, leaving a trailing gas stream resembling a comet's tail. However, a compact halo remains intact, and scientists predict this residual halo will not dissipate entirely. The research team studied the LMC's halo by analyzing the light from 28 quasars, exceptionally bright active galactic nuclei that act as "lighthouse beacons" across the universe. This light enables scientists to detect the halo gas indirectly, as the gas absorbs some of the quasars' light. The lines in the illustration represent the path of the Hubble Space Telescope's observations, from its orbit around Earth to the distant quasars, passing through the LMC's gas halo.
