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.

APOD: 2025 January 30 - Hydrogen Clouds of M33 Explanation: Gorgeous spiral galaxy Messier 33 seems to have more than its fair share of glowing hydrogen gas. 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.

2025年1月30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.

This is my first photo with the new telescope: Newton Tecnosky Carbon 200/800. I collected 18 hours of broadband signal and 9 hours with the Optolong L-Ultimate filter, under the skies of the Italian ...

距離約3百萬光年遠的m33，又名為三角大星系，是本星系群的大成員之一。 這幅清晰的 星系影像 ，呈現了此星系中心約30,000光年的區域。 影像的主題則是M33裡，稱為 HII區 的泛紅電離氫氣雲。

The portrait features M33'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.

2023年11月26日 · As the third-largest galaxy in our Local Group, after the Milky Way and Andromeda, M33 is a spiral galaxy located in the constellation Triangulum. It is a popular target for amateur astronomers due to its relatively large size and proximity, making it visible in dark skies with binoculars or a small telescope.
