2024年7月12日 · The distorted spiral galaxy, the Penguin, and the compact elliptical galaxy, the Egg, are locked in an active embrace. A new near- and mid-infrared image from the James Webb Space Telescope, taken to mark its second year of science, shows that their interaction is marked by a faint upside-down U-shaped blue glow.

旋涡星系（Spiral Galaxy），是观测到的数量最多的一种星系，因其形状似旋涡而得名。 旋涡星系在其对称面附近含有大量的弥漫物质，从正面看，形状像旋涡；从侧面看，便呈梭状。

5 天之前 · This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms, and bright blue star clusters. Also captured in the upper left-hand corner is a far closer object: a star just 577 light-years away in our own galaxy. UGC 5460 has hosted two recent supernovae: SN 2011ht and SN 2015as.

2025年2月17日 · The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope Picture of the Week is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms and bright blue star clusters.

2024年7月21日 · Messier 106, also known as NGC 4258, is an intermediate spiral galaxy located in the constellation Canes Venatici. It lies at a distance of roughly 23 million lightyears and spans some 135.000 ly in diameter.

2024年11月14日 · This sharp image from the James Webb Space Telescope‘s Mid-Infrared Instrument (MIRI) reveals stunning details of this magnificent spiral in infrared light. Webb’s field of view stretches about 60,000 light-years across NGC 1365, exploring the galaxy’s core and bright newborn star clusters.

Explanation: The largest photomosaic ever assembled from Hubble Space Telescope image data is a panoramic view of our neighboring spiral Andromeda Galaxy. With 600 overlapping frames assembled from observations made from July 2010 to December 2022, the full Hubble Andromeda Galaxy mosaic spans almost six full moons across planet Earth's sky. A ...

2024年8月9日 · Messier 106 is one of the brightest and nearest spiral galaxies to our own and two supernovae have been observed in this galaxy in 1981 and 2014. At its heart, as in most spiral galaxies, is a supermassive black hole, but this one is particularly active.

2024年4月18日 · This Hubble Space Telescope image of the barred spiral galaxy UGC 12158 looks like someone took a white marking pen to it. In reality it is a combination of time exposures of a foreground asteroid moving through Hubble's …
