In 1998, during the first Space Shuttle mission to the International Space Station, NASA unknowingly captured a picture of ...

The bold question-askers at What If warn how a black neutron star could destabilize Earth’s orbit and wreak havoc.

A new study says that a star’s orbit may have revealed Earth’s nearest black hole. Further, the findings by the researchers leading the study could point toward the existence of more dormant ...

The average EarthSun distance in Earth's orbit around the Sun is 150 million kilometres. If you've ever been taught about how Earth orbits around the Sun, you might well think our planet travels ...

Oh, Jupiter. If only the gas giant shifted its orbit slightly, becoming more eccentric (read: oval-shaped), it could transform the shape of Earth’s orbit, too, causing parts of the blue planet ...

The true shape of Earth’s orbit: nearly a circle. Length a is the semi-major axis of the ellipse and b the semi-minor axis.

Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago. Researchers found the shape of Earth's orbit, or eccentricity ...

For the study, the researchers analyzed data from NASA’s now-retired Kepler Space Telescope regarding the orbital shapes, also known as eccentricities, on 1,646 exoplanets whose sizes range between ...

Until 10 years ago, relatively few things were in Earth’s orbit. Now it’s a traffic jam. AN EVEN MORE INTERNATIONAL SPACE STATION When China launched the last stage of its space station in ...

One of China’s Long March 6A rockets has broken apart in low-Earth orbit and created a debris cloud consisting of hundreds of pieces, according to multiple space debris-tracking entities. The ...

Given this, Barker et al. estimate that – in the absence of rising anthropogenic greenhouse gasses – the next glacial period would likely begin within the next 11,000 years as Earth’s ...
