Pulsar ambassador Graeme Donald captured stunning footage of the biggest bird in the world, the Ostrich from South Africa. This fully grown male weighs an impressive 157 kg and stands as tall as a human, showcasing just how powerful and majestic these birds are. The footage was taken with the Oryx LRF XG35, highlighting its incredible thermal clarity and details, even when observing wildlife at a distance. Graeme’s experience in the field, combined with the Oryx’s advanced features, allows for a

This is what a real distant pulsar sounds like! These sounds come from real radio waves emitted by the brightest pulsars in the sky, captured by some of the world’s largest radio telescopes. #pulsar #velastar #space #astronomy | Nikola Sagan

Pulsar: A pulsar (pulsating star, on the model of quasar) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense and have short, regular rotational periods
