The 100-year-old symmetry theorem that is still changing physics today

Emmy Noether was hailed as a mathematical genius in her own time. And her theorem on symmetry is still driving new discoveries in particle physics and quantum computing today

Caption This image from NASA?s James Webb Space Telescope shows a portion of the Leo P dwarf galaxy (stars at lower right represented in blue). Leo P is a star-forming galaxy located about 5 million light-years away in the constellation Leo. A team of scientists collected data from about 15,000 stars in Leo P to deduce its star formation history. They determined that it went through three phases: an initial burst of star formation, a ?pause? that lasted several billion years, and then a new round of star formation that is still continuing. The image from Webb?s NIRCam (Near-Infrared Camera) combines infrared light at wavelengths of 0.9 microns (represented in blue), 1.5 microns (green), and 2.77 microns (red). The stars in Leo P appear blue in comparison to the background galaxies for several reasons. Young, massive stars that are common in star-forming galaxies are predominantly blue. Leo P also is extremely lacking in elements heavier than hydrogen and helium, and the resulting ?metal-poor? stars tend to be bluer than Sun-like stars. A bubble-like structure at bottom center is a region of ionized hydrogen surrounding a hot, massive O-type star.

n 2025 BepiColombo image1 Top three images from BepiColombo's sixth Mercury flyby 09/01/2025 619 views 4 likes ESA / Science & Exploration / Space Science / BepiColombo On 8 January 2025, the ESA/JAXA BepiColombo mission flew past Mercury for the sixth time, successfully completing the final ?gravity assist manoeuvre? needed to steer it into orbit around the planet in late 2026. The spacecraft flew just a few hundred kilometres above the planet's north pole. Close-up images expose possibly icy craters whose floors are in permanent shadow, and the vast sunlit northern plains. At 06:59 CET, BepiColombo flew just 295 km above Mercury's surface on the planet's cold, dark night side. Around seven minutes later, it passed directly over the Mercury's north pole before getting clear views of the planet's sunlit north. European Space Agency (ESA) Director General Josef Aschbacher revealed the first image during his Annual Press Briefing on 9 January. As during BepiColombo's previous flybys, the spacecraft's monitoring cameras (M-CAMs) did not disappoint. This flyby also marks the last time that the mission's M-CAMs get up-close views of Mercury, as the spacecraft module they are attached to will separate from the mission's two orbiters ? ESA?s Mercury Planetary Orbiter and JAXA?s Mercury Magnetospheric Orbiter ? before they enter orbit around Mercury in late 2026. Celebrating the M-CAMs' final hurrah, let's explore the best three images from BepiColombo's sixth close encounter with the little planet, and what they reveal about mysterious Mercury.
