Heliophysics Big Year
The 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.

Welcome to our redesigned NASA Science website

A gateway to our missions, research, and engagement efforts.

The Science Mission Directorate inspires the learners of today and develops the leaders of tomorrow. One of our key strategies is to purposefully and actively engage with audiences and learners of all ages to share the story of NASA’s integrated science program. From exoplanet research to better understanding Earth’s climate to understanding the influence of the sun on our planet and the solar system, our work is interdisciplinary and collaborative. Similarly, this new website showcases our work in a crosscutting way so that we may build stronger connections with you, our most important stakeholder. Together, we lead a globally interconnected program of scientific discovery that encourages innovation, positively impacts people’s lives, and is a source of inspiration.
