(Phys.org)—Periodic comet 17P/Holmes is usually a very faint object. However, during its historic outburst in October 2007, when the comet's coma expanded to a diameter greater than that of the sun, it became visible to ...
(Phys.org)—A new study demonstrates that researchers can control the distance between two molecules such that they can adjust the step size to as small as Bohr's radius. This proof-of-concept study using DNA origami techniques ...
Astronomers from the University of Cambridge have developed a new, highly accurate method of measuring the distances between stars, which could be used to measure the size of the galaxy, enabling greater understanding of ...
