NASA’s PUNCH mission captured a stunning photo of the moon against a dark sky while testing its instruments.

Launched in March, PUNCH is a group of four small satellites studying the solar wind—the charged particles from the sun that cause space weather affecting Earth.

Using an “occulter” to block the sun’s bright light, PUNCH reveals the sun’s corona and plasma structures that help scientists understand and predict geomagnetic storms.

Working alongside NASA’s Parker Solar Probe, PUNCH aims to improve our knowledge of solar activity and protect Earth from space weather disruptions, Live Science has reported.

The mission will begin full science operations in June, with data openly available to the public.
