Explanation: The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way.

A prominent member of the Local Group of galaxies, M33 is also known as the Triangulum Galaxy and lies a mere 3 million light-years away. The galaxy's central 60,000 light-years or so are shown in this sharp galaxy portrait. The portrait features M33's reddish ionized hydrogen clouds or …

2019年10月14日 · Based on image data from space and ground-based telescopes, the portrait of M33 shows off the galaxy's reddish ionized hydrogen clouds or HII regions. Sprawling along loose spiral arms that wind toward the core, M33's giant HII regions are some of the largest known stellar nurseries, sites of the formation of short-lived but very massive stars.

經常稱為風車星系或 三角大星系 的M33，直徑超過50,000光年，在 本星系群 裡，是大小僅次於仙女座大星系（M31）和我們銀河系的第三大星系。 離銀河系 大約 3百萬光年遠的M33，咸認是仙女座大星系的伴星系之一；也因此，位在這二個星系的 天文學家，應該都能看見對方宏偉的旋渦狀恆星系統。 至於在地球拍攝的這幅 高清組合影像，則精采的呈現了M33鬆散螺旋臂上的泛藍星雲和粉紅 恆星形成區。 位在星系核心4點鐘方向的洞穴狀 NGC 604，就是其中最明亮的恆星形成 …

2022年11月3日 · Good morning, Rallypoint, and welcome to the November 3rd edition of Astronomy Picture of the Day (APOD): "M33: The Triangulum Galaxy." M33 lies approximately 3,000,000 light years from Earth in the constellation (appropriately name) Triangulum.

2021年10月2日 · Sprawling along loose spiral arms that wind toward the core, M33's giant HII regions are some of the largest known stellar nurseries, sites of the formation of short-lived but very massive stars. Intense ultraviolet radiation from the luminous massive stars ionizes the surrounding hydrogen gas and ultimately produces the characteristic red glow.
