SPHEREx

Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer

future Mission

The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide the first all-sky spectral survey. Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe.

Big Bang Infographic showing the timeline of the history of the big bang and the formation of the building blocks of the universe. he history of the universe is outlined in this infographic. It starts with Inflation, then the first particles in 1 microsecond, followed by first nuclei (10 seconds); first light (300,000 years); first stars (200 million years); galaxies and dark matter (400 million years); dark energy (10 billion years); present (13.8 billion years).

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.
