Trying to understand the Universe is often less about seeing it clearly and more about accepting how quickly our intuition breaks down. If Earth were reduced to the size of a small 12 centimeter ...

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) have, for the first time, achieved a precise size measurement of small dust particles around a young star through radio-wave ...

WD 1856 b is the only confirmed case of a planet that survived the death of a Sun-like star. It’s a Jupiter-size world ...

Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction. Measuring the mass of such a small planet based ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Researchers have discovered a planet which, by all intents and purposes, should not be there. The world, coined WD 1856 b, is slightly larger than Jupiter and circles a dead star only about the size ...
