Galaxies imaged in spectacular detail by Hubble’s Wide Field Camera 3 (WFC3). Credit: ESA/Hubble & NASA, T. Treu, Acknowledgment: J. Schmidt Clustered at the center of this image are six luminous spots of light, four of them forming a circle around a central pair. Appearances can be deceiving, however, as […]

An image taken by the Curiosity Rover MastCam instrument shows layered sedimentary rocks composing Mount Sharp. The rover has been driving from the floor of Gale crater up through the rocks within these hills in order to understand how the rocks change from lower in the section (older) to higher […]

Brown dwarfs, such as the one seen in this illustration, are actually orange or red, and they glow brightest in the infrared part of the spectrum. PHOTOGRAPH: NASA/JPL-CALTECH/2MASS The brown dwarf isn’t a star and it’s not a planet. But it’s illuminating the murky borderlands that separate the two. DAN CASELDEN […]

This region is known to be covered by large lava deposits probably from the nearby Tharsis Montes […]

Deep streams of data from Earth-imaging satellites arrive in databases every day, but advanced technology and expertise are required to access and analyze the data. Now a new system, developed in research based at the University of California, Berkeley, uses machine learning to drive low-cost, easy-to-use technology that one person […]

Artist’s impression of the internal structure of Mars. Credit: © IPGP / David Ducros The first direct seismic observations from NASA’s InSight lander, presented in three studies in this issue, provide clues to the composition of Mars. Researchers across these studies report preliminary findings from the Insight mission and begin to map […]

Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere layer corresponds to temperatures, from hot to cold, in this order: white, yellow, bright red and lastly, dark red. The aurorae are the hottest regions […]
