案例简介：📸解释: @ NASAHubble的标志性照片✨我们得到了很多问题-哈勃如何拍摄其图像？颜色是真的吗？今天，我们在这里打破这一切。🤳与手机相机不同，我们的太空望远镜不会拍摄快照并将图像恢复为彩色。相反，它的相机拍摄的图像在很宽的波长范围内，以灰度下降到地球。科学家通过在望远镜上使用不同的滤色器进行曝光，为每个滤色器分配与该滤色器的波长相对应的颜色并组合图像来创建彩色图像。👁许多全彩色哈勃图像是三个单独曝光的组合-每个都是在红色，绿色和蓝色光线下拍摄的。当混合在一起时，这三种颜色可以再现人眼可见的几乎任何颜色的光。这就是电视，电脑显示器和摄像机如何重新创建颜色来显示图片!因为我们看不到紫外和红外光谱中的颜色，所以科学家们使用可见光光谱中最接近的颜色来表示这些信息。💫哈勃图像中的颜色用于突出所研究天体的有趣特征。以这个环状星云为例!这里以可见光显示，深蓝色中心代表氦，内环的青色是氢和氧的辉光，外环的红色来自氮和硫。信用: NASA，ESA和哈勃遗产 (STScI/AURA)-ESA/哈勃合作 # FunFacts # NowYouKnow # Hubble # NASA # PhotographyDaily # Cosmos

案例简介：📸 EXPLAINED: @NASAHubble’s iconic photos ✨ We get the question a lot – how does Hubble take its images? Are the colors real? Today, we’re here to break it all down. 🤳 Unlike a cell phone camera, our space telescope doesn't take a snapshot and get the image back in color. Rather, its cameras take images over a broad range of wavelengths that come down to Earth in grayscale. Scientists create color images by taking exposures using different color filters on the telescope, assigning a color to each filter that corresponds to the wavelength of that filter, and combining the images. 👁️ Many full-color Hubble images are combinations of three separate exposures — one each taken in red, green, and blue light. When mixed together, these three colors can recreate almost any color of light that is visible to human eyes. That’s how televisions, computer monitors, and video cameras recreate colors to show a picture! Because we can’t see the colors in the Ultraviolet and Infrared spectrum, scientists use the closest approximation of them in the visible light spectrum to represent that information. 💫 Color in Hubble images is used to highlight interesting features of the celestial object being studied. Take this Ring Nebula for example! Shown here in visible light, the deep blue center represents helium, the cyan color of the inner ring is the glow of hydrogen and oxygen, and the reddish color of the outer ring is from nitrogen and sulfur.
