NASA Explains Why Earth Appears Glowing Orange In Stunning Space Photo
NASA has shared a beautiful image taken from the International Space Station (ISS), which shows Earth wrapped in…
Atomic oxygen in low Earth orbit slowly eats spacecraft surfaces, and the ISS survives because engineers learned to coat, test, and replace the materials most vulnerable to it
Roughly 400 kilometres above Earth, the International Space Station is flying through a kind of invisible chemical weather.…
A NASA satellite launched in 1976 carries a Carl Sagan–designed plaque sealed inside its core, mapping Earth’s continents 268 million years ago, at launch, and 8.4 million years from now — and that last date is no accident, because it’s roughly when the satellite is expected to fall back to Earth and finally be opened.
On 4 May 1976, NASA launched a satellite called LAGEOS-1 from Vandenberg Air Force Base in California. It…

The Vela satellites were built to catch secret nuclear tests, but they accidentally recorded flashes from deep space that opened a new branch of astrophysics
The Vela satellites were not built to study stars. They were built to watch for nuclear weapons. In…
The Hubble Deep Field began as a gamble on a tiny patch of sky that had been chosen because it looked almost empty, and it ended by revealing nearly 3,000 galaxies hiding in what seemed like nothing.
In December 1995, the Hubble Space Telescope spent ten days staring at a small, deliberately unremarkable patch of…
Scientists discover a shortcut to the moon that NASA missed
Getting to the moon is partly a fuel problem. Plotting the most efficient path between two points in…
Titan’s atmosphere is thicker than Earth’s, its rivers and lakes are made of methane and ethane, and NASA is sending a nuclear-powered drone there because on Saturn’s largest moon, flying may be easier than driving.
Titan, the largest moon of Saturn, has a denser atmosphere than Earth and a surface where rain, rivers,…
