NASA shares video showing sun’s ‘invisible magnetic field’: astronomers excited
Houston: NASA has once again done a marvelous job. The top US space agency has given many reasons to rejoice to space enthusiasts across the world by sharing an impressive video of solar flares with the whole world.
Latest reports suggest that NASA space telescope actually caught a glimpse of a cascading series of solar flares arching around the sun’s magnetic field. While solar flares suggest activities in sunâ€™s magnetic field, the solar flares from the earth look very impressive indeed.
The video that is going viral for the last one days shows invisible magnetic lines where the Sun seems as a mass of noodle-like energy in constant flux, pulsating and sending out bursts of magnetically-charged particles. The scientists have turned to a combination of real time observations and computer simulations to assess how material courses through the solar upper atmosphere – the million-degree corona which cannot be seen in the visible light.
As far as astronomers are concerned they find solar flares fascinating. The Sun’s magnetic field is responsible for everything from the solar explosions that cause space weather on the earth – such as auroras – to the interplanetary magnetic field and radiation through which our spacecraft journeying around the solar system should travel. According to NASA, the sun is made of plasma, a gas-like state of matter in which ions and electrons have separated, creating a super-hot mix of charged particles.
According to space experts, the footpoints on the Sun’s surface or photosphere of these magnetic loops can be accurately measured using an instrument called a magnetograph, which measures the direction and strength of magnetic fields.
