NASA | Many Views of a Massive CME

The video discusses a powerful coronal mass ejection (CME) from the sun, detailing its speed, mass, and impact. NASA's heliophysics fleet, including the Solar Dynamics Observatory and STEREO spacecraft, captured high-resolution images of the event. These observations help in understanding and predicting solar outbursts. The video also highlights the effects of CMEs on spacecraft instruments and the role of data in modeling these solar phenomena.

What is a coronal mass ejection (CME)?

• A small solar flare

• A type of solar wind

• A massive cloud of plasma ejected from the sun

• A sunspot on the solar surface

Which NASA observatory provided a high-resolution view of the sun during the CME event?

• James Webb Space Telescope

• Chandra X-ray Observatory

• Hubble Space Telescope

• Solar Dynamics Observatory (SDO)

What is the purpose of the coronagraphs on the STEREO satellites?

• To measure solar wind speed

• To block the bright solar disc and view the corona

• To capture images of sunspots

• To detect solar flares

Which observatory has been observing the sun since 1995 and contributed to the CME analysis?

• Hubble Space Telescope

• Solar and Heliospheric Observatory (SOHO)

• Kepler Space Telescope

• Chandra X-ray Observatory

How do the observations from NASA's heliophysics fleet help scientists?

• They help in mapping the surface of Mars

• They provide data for weather forecasting on Earth

• They improve understanding and predictions of solar outbursts

• They assist in tracking asteroids near Earth
