从侧面看我们的银河系是什么样子的？因为我们在里面，人类无法得到真实的画面。然而，最近，利用来自欧洲航天局盖亚任务的超过10亿颗恒星的位置数据，绘制了这样一幅地图。由此产生的特色插图表明，就像许多其他螺旋星系一样，我们的银河系有一个非常薄的中央圆盘。我们的太阳和我们晚上看到的所有恒星都在这个圆盘上。虽然之前是假设的，但更令人惊讶的是，这个圆盘的外缘是弯曲的。我们银河系扭曲的中央带的颜色主要来自黑暗的尘埃、明亮的蓝色恒星和红色的发射星云。虽然数据分析仍在进行中，但在一次成功的任务后，盖亚于今年3月停止了活动。探索你的宇宙：随机APOD生成器

What does our Milky Way Galaxy look like from the side? Because we are on the inside, humanity can’t get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESA’s Gaia mission. The resulting featured illustration shows that just like many other spiral galaxies, our Milky Way has a very thin central disk. Our Sun and all the stars we see at night are in this disk. Although hypothesized before, perhaps more surprising is that the disk appears curved at the outer edges. The colors of our Galaxy's warped central band derive mostly from dark dust, bright blue stars, and red emission nebulas. Although data analysis is ongoing, Gaia was deactivated in March after a successful mission. Explore Your Universe: Random APOD Generator
