Pulsar1970-01-01T00:00:00+00:00Pulsars are very rapidly spinning neutron stars surrounded by fantastically powerful magnetic fields (magnetospheres). The magnetosphere is shown as a blue translucent donut sectioned across.Pulsars emit beams of radiation (purple light) from their mag...PT9Shttps://d3e1m60ptf1oym.cloudfront.net/b1b35f57-3c29-4e05-9bfc-d722cf0fb2d3/PULSAR-FHD-Russell-Kightley_xlarge.jpghttps://d3e1m60ptf1oym.cloudfront.net/b1b35f57-3c29-4e05-9bfc-d722cf0fb2d3/PULSAR-FHD-Russell-Kightley_mp4_hd_video.mp4https://www.scientific.pictures/-/galleries/astronomy/-/medias/b1b35f57-3c29-4e05-9bfc-d722cf0fb2d3/pricehttps://www.scientific.pictures/-/galleries/astronomy/-/medias/b1b35f57-3c29-4e05-9bfc-d722cf0fb2d3/price
Rosette Orbital
Rosette Orbital animation showing a body attracted by a force proportional to 1/r. The simulation begins with a body (or satellite, shown as a red ball) with a certain velocity that is tangential to an point attractor (shown as a yellow ball in the centre) whose force diminishes with distance (i.e. is inversely proportional to r. The resulting orbit creates a flower-like pattern or rosette. Notice how the object speeds up as it approaches the attractor. This is shown by the tracer balls being more widely spaced. Once the movie has fully appeared you can move the slider back and forth to see these effects at different speeds.

Sundials1970-01-01T00:00:00+00:00SUNDIAL: simulation of shadow cast by a sundial on Midsummer Day.
SUNDIALS have been used since antiquity to tell the time by the position of the shadow cast by a gnomon (the sticking out bit of a sundial). Early examples were simply towers whose shad...PT8Shttps://d3e1m60ptf1oym.cloudfront.net/6126c233-8002-4c7f-b370-306596353aa6/Sundial-4-views-FHD-Russell-Kightley_xlarge.jpghttps://d3e1m60ptf1oym.cloudfront.net/6126c233-8002-4c7f-b370-306596353aa6/Sundial-4-views-FHD-Russell-Kightley_mp4_hd_video.mp4https://www.scientific.pictures/-/galleries/astronomy/-/medias/6126c233-8002-4c7f-b370-306596353aa6/pricehttps://www.scientific.pictures/-/galleries/astronomy/-/medias/6126c233-8002-4c7f-b370-306596353aa6/price
