Assuming that the Nova 1437 ejecta initially had the same proper motion that we measure for the cataclysmic variable, and that this value has been halved every 75 years since, then the shell ...

Even if the Milky Way and Andromeda don’t collide in the next 10 billion years, though, that won’t be the end of the story.

Flies can therefore process a vast amount of information about proper motion and movement in their environment in real time - a feat that no computer, and certainly none the size of a fly's brain, can ...

With stars creating recognisable patterns and constellations that have guided and enthralled humanity for generations, the ...

Kapteyn’s Star, a 9th-magnitude red subdwarf, speeds through space with a proper motion second only to Barnard’s Star. This nomadic wonder is visible in the northern reaches of the ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) and by analyzing archival Arecibo Observatory data, astronomers have investigated a distant pulsar designated PSR B1310+18A.
