NASA | IRIS Spots Its Largest Solar Flare

On January 28th, 2014, Iris observed a significant solar flare, the largest it has seen. The video explores the Sun's chromosphere, a dynamic region, and explains how scientists use spectra to map the movement of solar material in detail.

What significant event did Iris observe on January 28th, 2014?

• A lunar eclipse

• A solar flare

• A comet passing by

• A meteor shower

Which region of the Sun does Iris provide a better view of?

• The chromosphere

• The core

• The photosphere

• The corona

What is the purpose of the moving vertical line in the images captured by Iris?

• To focus on specific temperatures of solar material

• To capture images of solar storms

• To measure the Sun's brightness

• To track solar wind speed

What is the individualized temperature data called that scientists use to map solar material movement?

• Solar mapping

• Thermal imaging

• Spectra

• Temperature profiling

How does the Spectra data help scientists in understanding solar flares?

• By analyzing the Sun's core temperature

• By measuring the Sun's magnetic field

• By mapping the movement of material in the flare

• By predicting future solar flares
