NASAさんのインスタグラム写真 - (NASAInstagram)「It’s October 3rd. 📝 🩷 It may not be Wednesday, but the Cartwheel galaxy is still wearing pink! This version of one of @NASAWebb’s early images combines its infrared data with X-rays collected by @chandraxray, giving a more detailed view! Image credits: X-ray: NASA/CXC; IR: NASA/ESA/CSA/STScI Image description: An image of the Cartwheel galaxy, a neon pink disk with an outer ring, and a solid, slightly off-center spiraling core. Linking the smooth core and the irregular outer ring are wispy pink plumes of silicate dust which resemble twisted spokes on a bicycle wheel. At the upper left of the image are two companion galaxies, also pink in color. In this image the companion galaxies appear to be about the same size as the core of the Cartwheel galaxy. One companion galaxy is shaped like a backwards S, and is marked by bright white dots and tangles of fine crinkly lines. Below it, the second companion galaxy appears delicate and smooth, like a faded swirl of cotton candy.」10月4日 0時44分
