Unlike the typical blue-and-green depiction of Earth, this photo shows the planet in a mossy green hue, framed by a thin white band marking the atmosphere’s edge against the void of space. The Milky Way appears oblong and edge-on, offering a glimpse across its vast diameter.

The overly sterile environment of the International Space Station is missing important microbes, a new detailed map shows. If we want to live off Earth, we may need to take more of our bacterial frien

A new study found that the International Space Station (ISS) might actually be overly sterile. While having fewer microbes might initially sound like a good thing, it could actual

The ISS’s microbial environment most closely resembles a hospital isolation room. It could be making astronauts sick.

Astronauts in isolated space habitats could benefit from the intentional fostering of diverse microbes from humanity's evolutionary past, a new study suggests.

Turns out, being too clean can be a bad thing. Scientists suggest the International Space Station (ISS) is so sterile that it may be making astronauts less healthy—and could even lead to problems like skin rashes,

Some of the health effects astronauts suffer on the International Space Station (ISS) may not be a consequence of weightlessness, as previously thought, but of the ISS being too clean, a new study proposes.
