Though it looks like a bubble or eye from Earth's point of view, the Helix is actually a trillion-mile-long tunnel of glowing gases This Hubble mosaic is the highest resolution image ever made of the ...

The soft light from a nebula may also come from the ambient radiation released by the nebular cloud itself. This type of cosmic cloud is known as an emission nebula. One of the most famous is the ...

A new study has discovered the origin of the persistent emission of radiation observed in some deep-space fast radio bursts.

The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial ...

The radiation energizes the gas, causing different gases to glow, or emit, at characteristic wavelengths, hence why such a nebula is called an "emission nebula." The filters used in this image ...
