Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites ...

Climate change isn’t just warming the planet—it’s reshaping space. As greenhouse gases trap heat in the lower atmosphere, the upper atmosphere cools and contracts, reducing the drag that naturally ...

A near-miss earlier this year between NASA's TIMED spacecraft and the Russian Cosmos 2221 satellite was even closer ... Purple may be key to finding planets capable of hosting alien life, study ...

Greenhouse gas emissions could affect satellite launches in the future, new research suggests. As it builds up, the pollution causes Earth’s upper atmosphere to contract, potentially raising the risk ...

If we don’t manage this activity carefully and work to reduce our emissions, space could become too crowded, leading to more collisions and debris ... MIT studied the effect on safe satellite capacity ...

It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the ...

until a space station discovers a fiery unknown planet heading for a collision to destroy all humanity!" Scientists try to prevent a collision between Earth and a planet that is heading for it.

Scientists think the significant tilts in the rotational axes of Saturn, Uranus, and Neptune could also indicate that the planets sustained massive collisions long ago. To look into Jupiter's past ...
