从顶部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，我们的银河系也有独特的旋臂。我们的太阳和我们在晚上看到的大多数明亮的恒星都在一条臂上：猎户座。盖亚的数据支持了之前的说法，即我们的银河系有两个以上的旋臂。我们银河系的中心有一个显眼的酒吧。我们银河系薄盘的颜色主要来自于深色尘埃、明亮的蓝色恒星和红色发射星云。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。拼图挑战：当天的天文学难题

What does our Milky Way Galaxy look like from the top? 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 distinct spiral arms. Our Sun and most of the bright stars we see at night are in just one arm: Orion. Gaia data bolsters previous indications that our Milky Way has more than two spiral arms. Our Galaxy's center sports a prominent bar. The colors of our Galaxy's thin disk derive mostly from dark dust, bright blue stars, and red emission nebula. Although data analysis is ongoing, Gaia was deactivated in March after a successful mission. Jigsaw Challenge: Astronomy Puzzle of the Day
