It seems as if Earth's atmosphere is incredibly thin, wrapped tightly around our planet. In fact, the atmosphere consists of multiple layers, with some scientists of the opinion that the atmosphere ...

Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...

A former NASA scientist explains how we know whether Blue Origin New Shepard made it to space, and how its altitude compares ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry ...

Laid down over millions of years, these rock layers contain a permanent record ... Some three billion years ago, the Earth's atmosphere was virtually devoid of oxygen. At about 2.4 billion years ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

The ozone layer is a thin shield of gas in the Earth’s atmosphere that protects the planet, absorbing the sun’s ultraviolet (UV) rays and helping to preserve all life on the planet.

Imminent loss of NASA's Aura and Canada's SCISAT will severely diminish scientists’ ability to monitor ozone-depleting substances in the stratosphere.

Earth's rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet's molten youth using advanced quantum mechanical simulations, revealing ...
