A white line vertically cuts through the middle of the image.Against a black background, the total solar eclipse. It is a black circle surrounded by white, wispy streams of light that flow away from the black circle in every direction.5 min readThe April 8 Total Solar Eclipse: Through the Eyes of NASAArticle2 months ago5 min readHow NASA’s Roman Telescope Will Measure Ages of StarsArticle2 months agoA model showing the evolution of the solar corona prediction for April 8, 2024. It shows the solar corona as white light with defined structure encircling a black disk. The structured light ripples and changes throughout the animation, which represents coronal predictions.5 min readScientists Use NASA Data to Predict Solar Corona Before EclipseArticle3 months agoKeep ExploringDiscover More Topics From NASAJames Webb Space TelescopeThe image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.Perseverance RoverParker Solar ProbeJuno
