A black, deep space image is dominated by what appears to be a large snowflake-like feature with a bright white core and 8 pinkish orange spikes. It is surrounded by additional wisps of pinkish orange and blue gas.

'Great Debate' Bibliographies

Kepler-69c is 70 percent larger than Earth. It completes one orbit around its star every 242 days.

The 'Great Debate': What Really Happened

This visualization is a flight through the 'cosmic web', the large scale structure of the universe. Each bright knot is an entire galaxy, while the purple filaments show where material exists between the galaxies. To the human eye, only the galaxies would be visible, and this visualization allows us to see the strands of material connecting the galaxies and forming the cosmic web.This visualization is based on a scientific simulation of the growth of structure in the universe. The matter, dark matter, and dark energy in a region of the universe are followed from very early times of the universe through to the present day using the equations of gravity, hydrodynamics, and cosmology. The normal matter has been clipped to show only the densest regions, which are the galaxies, and is shown in white. The dark matter is shown in purple. The size of the simulation is a cube with a side length of 134 megaparsecs (437 million light-years).
