Two astronomers from the University of Groningen (The Netherlands) have developed a software library that can effortlessly generate visualisations based on hundreds of millions of data points. Maarten Breddels and Jovan Veljanoski ...
This image captures the intensity of the jets and vortices in Jupiter's North North Temperate Belt.
Our galaxy produces and destroys the element aluminum-26 in the process of making magnesium-26. As it forms, it can be momentarily "stuck" in a mirror-image (isomeric) state. Getting stuck lets other reactions occur that ...
A little stream in the south of England could guide the way towards finding evidence for ancient life on Mars, in the form of fatty acids preserved in an iron-rich mineral called goethite.
Have you ever considered yourself capable of manipulating gravity? When you grip an object, you are doing just that.
The White House is establishing a new policy for reducing satellite clutter in space.
President Donald Trump boasted Monday of the US commercial space industry's deep wallet and enterprising spirit, and vowed US dominance in exploration of the Moon and Mars, as well as any future space race.
In 2006, NASA's Mars Reconnaissance Orbiter (MRO) established orbit around the Red Planet. Using an advanced suite of scientific instruments – which include cameras, spectrometers, and radar – this spacecraft has been ...
A proposed space mission known as the Comet Astrobiology Exploration Sample Return (CAESAR) could expand the knowledge of the origin and history of the comet 67P/Churyumov–Gerasimenko. If selected by NASA, it will return ...
