Hot blue stars shine brightly in this beautiful, recently formed galactic or “open” star cluster. Open cluster NGC 3293 is located in the constellation Carina, lies at a distance of about 8000 light years, and has a particularly high abundance of these young bright stars. A study of NGC 3293 implies that the blue stars are only about 6 million years old, whereas the cluster’s dimmer, redder stars appear to be about 20 million years old. If true, star formation in this open cluster took at least 15 million years. Even this amount of time is short, however, when compared with the billions of years stars like our Sun live, and the over-ten billion year lifetimes of many galaxies and our universe. Pictured, NGC 3293 appears just in front of a dense dust lane and red glowing hydrogen gas emanating from the Carina Nebula.

🔥✨ 在美麗的開放星團 NGC 3293 中，熱藍星明亮地閃耀。這個星團位於木乃伊（Carina）星座，距離我們約 8000 光年。研究顯示，這些年輕而明亮的藍星約有 600 萬年歷史，而那些較為暗淡、紅色的星星則約有 2000 萬年。若這個數據正確，這個開放星團的星形成過程至少持續了 1500 萬年。雖然這段時間對於恆星的生命週期而言相對較短，與我們的太陽和許多星系及宇宙的十億年生命相比，卻仍然令人驚豔。畫面中，NGC 3293 赫然出現在稠密的塵埃帶和源自木乃伊星雲的紅色氫氣當中。
