Astronomers have discovered a new type of "aurora" created by falling SpaceX rocket boosters that punch temporary holes in the ionosphere. Experts are concerned that these blood-red light shows could be causing unknown problems for astronomy and communication.

MBARI researchers came across a rarely seen dreamer anglerfish off California's coast. Video footage of the alien-looking fish only shows its silhouette because its skin is so dark it absorbs almost all of the light that hits it.

The sky's blueness isn't from reflecting the water. Instead, its color has to do with scattered light.

A striking new image shows bright orange auroras dancing in the night sky above Canada. But auroras should never be this color, so what's going on?

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise.

The James Webb Space Telescope has snapped a stunning image of a perfectly formed Einstein ring, which is also the most distant gravitationally lensed object ever detected.

The recent launch of a SpaceX Falcon 9 rocket in California created a gap in Earth's ionosphere, which resulted in a blood-red glow across the sky visible for hundreds of miles.

In back to back days, the sun appeared to melt into the horizon due to a trippy optical illusion called the "Omega sun."

The new panorama snapped by NASA's Curiosity rover combines photos from two different times of day to create a highly detailed image of the Red Planet.
