π Looking at this photo, does it feel like our Earth is really not as blue as it used to be? This set of photos was taken by the Deep Space Climate Observing Satellite (DSCOVR) of the United States from November 21 to 27, 2022, recording seven days of changes in China and the Asian region. The satellite is located at Lagrange point L1, about 1.5 million kilometers away from us!
πΈ Each photo is a snapshot of the Earth, recording the passage of time and subtle changes in our homeland. Follow me, I update the latest Earth photos every week, taking you to experience the breathing of the Earth in real time.
π The knowledge point has arrived! The DSCOVR satellite has been monitoring the solar wind since its launch in February 2015, which is crucial for our weather forecasting. If there is no warning from DSCOVR, geomagnetic storms may damage our power grid, telecommunications, aviation, and GPS systems.
π The L1 orbit is a special point between the Earth and the Sun, located approximately 1.61 million kilometers away from Earth. Here, DSCOVR can provide a 15 to 60 minute advance warning for coronal mass ejections (CMEs), helping us better predict the impact of geomagnetic storms.
π No matter how busy life is, don't forget to look up at the starry sky. Because every atom that makes up our body comes from the depths of the distant universe.
