A spacecraft ran by NASA has recorded an astonishing video of a minor explosion on the Sun’s surface. The close-up—that was recorded by the SDO (Solar Dynamics Observatory) on August 13 during a 2-h episode—demonstrates the flare mounting on the Sun’s edge prior to dropping back into it.
Small explosions can be difficult to notice particularly if they take place toward the Sun’s central part and are expected to be observed if they take place along the edge of the Sun, also called as the limb. The eruption was captured by the SDO in the intense ultraviolet light as the bare eyes cannot see specific wavelengths of sunlight.
The project scientist at Solar Dynamics Observatory, Dean Pesnell, said, “Specific wavelengths either don’t make it through the atmosphere of the Earth or cannot be noticed by our eyes, thus, we can’t use usual optical telescopes to observe the spectrum.”
At its crest, the plasma of the Sun—that is a hot gas ball composed up mainly of helium and hydrogen—increases numerous times the Earth’s diameter at velocities of up to around 540,000 km/h (335,500 mph). SDO was lifted-off in February 2010, with the objective to recognize the influence of the Sun on Earth by examining the solar atmosphere.
By understanding more regarding what takes place on the Sun, the researchers anticipate to envisage when strong solar events like the solar flares—radiation and high energy particles liberated from the Sun—and the coronal mass ejections—that entails a considerable discharge of plasma from the corona of the Sun—may take place.
On the other end, NASA has a competition for everyone. For a potential reward of $1 Million, the organization is inviting the people to propose ideas regarding how to convert CO2, which is abundant on Mars, into glucose that can more useful for consumption by a human.
