NASA’s James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique mid-infrared observations. Webb shows its rings as intricate clumps of dust. It’s also easier to see holes punched through the bright pink central region.NASA, ESA, CSA, STScI, Michael Ressler (NASA-JPL), Dave Jones (IAC) In this photo released on April 14, 2025, NASA’s James Webb Space Telescope revealed the gas and dust ejected by a dying star at the heart of NGC 1514. Using mid-infrared data showed the “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.
This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.
One of these stars, which used to be several times more massive than our Sun, took the lead role in producing this scene. “As it evolved, it puffed up, throwing off layers of gas and dust in in a very slow, dense stellar wind,” said David Jones, a senior scientist at the Institute of Astrophysics on the Canary Islands, who proved there is a binary star system at the center in 2017.

This project will develop piezoelectric-based power conversion for small power systems on the lunar surface. These piezoelectric systems can potentially offer high power density to significantly reduce size, weight, and cost. They can also offer high efficiency as well as resistance to the extreme lunar environment with its expected prolonged exposure to extreme cold and radiation. The effort will build and test prototype piezoelectric DC-to-DC power converters and DC-to-DC power supplies.
