玫瑰是红色的，星云也是红色的，这个情人节礼物是令人惊叹的景色！这是玫瑰星云（NGC 2237）的一张可爱的照片：明亮的年轻恒星在炽热的气体茎上绽放。玫瑰的蓝白色斑点是银河系中最明亮的恒星之一，其中一些燃烧的亮度是太阳的数百万倍。它们的恒星风将气体和尘埃从中心推开，形成了著名的玫瑰形状。虽然只有几百万年的历史，但这些大质量恒星已经接近生命的尽头，而嵌入在星云中的较暗的恒星将在未来的几十亿年里燃烧。鲜艳的红色来自氢气，被年轻恒星发出的紫外线电离。玫瑰的蓝白色中心是彩色映射，表明存在类似的电离氧。玫瑰星云让我们想起了编织在宇宙结构中的美丽和变化。

Roses are red, nebulas are too, and this Valentine's gift is a stunning view! Pictured is a loving look at the Rosette Nebula (NGC 2237): a cosmic bloom of bright young stars sitting atop a stem of glowing hot gas. The rose’s blue-white speckles are among the most luminous stars in the galaxy, with some burning millions of times brighter than the Sun. Their stellar winds sculpt the famed rose shape by pushing gas and dust away from the center. Though only a few million years old, these massive stars are already nearing the end of their lives, while dimmer stars embedded in the nebula will burn for billions of years to come. The vibrant red hue comes from hydrogen gas, ionized by the ultraviolet light from the young stars. The rose’s blue-white center is color-mapped to indicate the presence of similarly ionized oxygen. The Rosette Nebula reminds us of the beauty and transformation woven into the fabric of the universe.
