Scientists use Jupiter to search for dark matter

Jupiter's equatorial zone and Great Red Spot stand out in this infrared image from the James Webb Space Telescope because their high-altitude haze reflects sunlight well. Also notice the bright auroral emissions near the giant planet's north and south poles. Credit: NASA/ESA/Jupiter ERS Team; image processing by Judy Schmidt Dark matter is a mysterious substance

Looking into the Ring Nebula

This 1874 lithograph was created by Étienne Léopold Trouvelot using the 15-inch refractor at the Harvard College Observatory, in order to measure the extent of the nebula. A glass plate with dark black lines was placed at the focus of the telescope to mark the location. Not surprisingly, it shows no central star. Credit: Annals

JWST sees light invisible to the human eye. These scientists decide how to color it

Image processing at wavelengths outside the visible range of the spectrum can produce spectacular results, such as this iconic James Webb Space Telescope image of the so-called cosmic cliffs. Gas and dust in the field of view surround NGC 3324 near the Carina Nebula. The filters used in this image range from 0.9 to 4.7

Mars could have an amount of liquid water equivalent to that of an ocean buried in its crust

NASA's InSight lander ended its mission in 2022, but the data it collected revealed evidence of liquid water deep below the landing site. Credit: NASA/JPL-Caltech Deep beneath the surface of Mars lies a vast reservoir of liquid water, according to seismometer data from NASA's retired InSight lander. The findings, published Aug. 12 in Proceedings of
