<music throughout> How do solar flares impact Earth?

A solar flare is a burst of X-ray light.

4
00:00:08.130 --> 00:00:12.130
We know that the Sun influences space all the way down to the Earth's upper atmosphere.

A new study observed

00:00:16.180 --> 00:00:20.170
when the X-rays pulsated, so too did the lower ionosphere.

7
00:00:20.190 --> 00:00:24.200
The ionosphere is the lowest level of space, a region of the upper atmosphere

8
00:00:24.220 --> 00:00:28.230
about 30 - 600 feet above sea level.

00:00:28.250 --> 00:00:32.250
It is home to the aurora, the International Space Station, radio waves, and satellites.

10
00:00:32.270 --> 00:00:36.310
This is the first time we have seen its

11
00:00:36.330 --> 00:00:40.330
response synchronized with solar flare pulsations.

12
00:00:40.350 --> 00:00:44.360
Understanding how the Sun affects

13
00:00:44.380 --> 00:00:48.420
near-Earth space helps us learn how to protect astronauts and satellites close to home.
