Mars has almost no breathable oxygen. Here’s why that matters, and how NASA’s MOXIE could help future astronauts survive.
Mars has 99% less air than Earth, and almost none of it is oxygen. NASA hopes one rover tool could change that.

Distance, light speed, biology, and time may explain why alien civilizations never meet.
SpaceAlien civilizations have not visited Earth and never will, physicist claimsJoshua Shavit
In 2019, LIGO and Virgo detected GW190521—a mysterious gravitational wave that could mark either the colossal merger of two black holes or the tantalizing possibility of a wormhole echo from another universe.

The gravitational lens system JVAS B1938+666. The black ring and central dot show an infrared image of a distant galaxy distorted by gravitational lensing. The orange emission shows radio waves from the same system. The inset highlights a small "pinch" in the image caused by an additional dense object—about a million times the mass of the sun—shown as a white blob.
