Intense Photos of an Intense Solar Flare on Feb. 25

Shortly after midnight UTC on Feb. 25 (7:25 p.m. Feb. 24 EST), an intense solar flare sent a powerful burst of radiation out from the sun.

It was rated an X-4.9 flare. X-class solar flares are the most intense, and 4.9 denotes significant intensity within the X-class. An X2 is twice as intense as an X1, an X3 is three times as intense, and so on, explains NASA.

Solar flares can affect GPS and other signals, though the radiation cannot pass through the Earth’s atmosphere to affect people. The U.S. National Weather Service reports that the Earth and the flare are not currently aligned in such a way that an impact is expected, but monitoring will continue.

Astronomer and Slate blogger Phil Plait describes solar flares well: “Huge magnetic energies stored in sunspots … [get] let loose all at once, creating an explosion that dwarfs all of humanity’s weapons combined.”

    if we could figure out a way to harness the power of the Sun and capture all the energy it emits we can transform this entire planet, even the moon. why can’t giant Solar panels be placed on the moon then store the energy in some massive device and route it to Earth.
