Ghostly Stellar Tendrils of the Vela Supernova Remnant

The Detail in This New 1.3-Gigapixel Photo of a Supernova is Incredible

Using the remarkable 570-megapixel Dark Energy Camera (DECam), astronomers have made a 1.3-gigapixel image of the ghostly Vela Supernova Remnant. The beautiful, detailed, and colorful image is the largest DECam image ever at 35,786 by 35,881 pixels, putting even the highest-resolution medium-format interchangeable lens cameras to shame.

The Sun has been very active so far this month, with powerful sympathetic solar flares dazzling scientists and viewers alike and recent X-class flares making many wonder about communications network integrity. NASA's Solar Dynamics Observatory (SDO) constantly monitors the Sun and captures the recent powerful solar flares in exquisite detail across multiple wavelengths.

Webb Can See Far Enough to Test Theories of Dark Matter

The Hubble Space Telescope (HST) upended beliefs about the fundamental nature of the Universe, delivering evidence that the Universe was not slowing down, as gravity seemingly implied it must be, but expanding. 25 years later, the James Webb Space Telescope (JWST) can help scientists make another breakthrough.

Webb Finds That Many Old, Distant Galaxies Look Like Surfboards

While the James Webb Space Telescope has been busy helping scientists solve some of the greatest mysteries of the early Universe, the powerful telescope has also found that many distant galaxies have flattened oval disk and tube-like shapes, unlike the spiral and elliptical structures that are more typically seen in closer galaxies.

Webb helps scientists answer one of the most persistent questions about the nature of the early Universe.

Webb Answers One of the Early Universe’s Biggest Questions

While the James Webb Space Telescope (JWST) has delivered many beautiful images, its primary mission is to probe the early Universe and help humanity solve some of the most significant questions it faces. Webb has delivered on this promise by revealing, for the first time, what is in the local environment of galaxies in the very earliest days of the Universe.

Webb Identifies a Tiny Brown Dwarf That Defies Explanation

Even as telescopes and observatories uncover more details about space, it remains mysterious. One puzzle revolves around the "smallest object that can form in a star-like manner," according to NASA. With the help of the James Webb Space Telescope, scientists have identified a new record holder for that category: a free-floating brown dwarf.

AI models and energy use, negative impacts on the environment

Legislation Must Consider AI’s Energy Demands and Environmental Costs

Much of the focus on the potential hazards of generative AI technology has understandably been on how it impacts artists and copyright ownership, and how it could affect people's jobs and wages. New research shows that the dangers of generative AI go much further and may be catastrophic for the environment.

Hubble and Webb Deliver the Most Colorful View of the Universe Ever

Despite the somewhat familiar narrative that the James Webb Space Telescope has been built to supplant the aging Hubble Space Telescope, the two orbiting observatories regularly collaborate. Scientists have now combined data from Hubble and Webb to create the most colorful view of the Universe ever.
