IRAS is a sometimes forgotten spacecraft that proved that infrared astronomy had a bright future.

Explorer 1 marked the entry of science into what had been a military affair.

A new study shows the long-term effects of living in an irradiated environment. That could inform us about long-distance space trips.

A new study found that 3-in-50 Hubble shots have a satellite photobombing them — and that number will only go up as more satellites are launched.

The microgravity environment could hasted age-related issues.

The new alloy, built by researchers at NASA Glenn Research Center, is durable to even extreme heat stress. GRX-810 could enable hotter combustion reactions.

In addition to the Manhattan Project, J. Robert Oppenheimer also worked on many other areas of physics.

Here are our picks for the 12 best space images of the year.

Despite the best efforts of humans, the natural entropy of the space environment and the persnickety nature of rockets still occasionally prevail.

Sure, the computers in ‘Minority Report’ are cool, but a city with no traffic? Now there’s a utopia.
