What are the PUNCH satellites and what do they study?
The PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites are a set of four spacecraft designed to study the sun's outer atmosphere, known as the corona. Their primary goal is to understand how solar material is ejected into space and how it interacts with the solar wind, which can affect space weather and satellite operations on Earth.

How do PUNCH satellites complement the SPHEREx mission?
The PUNCH satellites complement the SPHEREx mission by focusing on solar phenomena while SPHEREx maps the universe in infrared light. Together, they provide a comprehensive view of both cosmic history and solar activity, allowing researchers to explore the connections between the sun and the broader universe.

Why is studying solar phenomena important?
Understanding solar phenomena is vital for several reasons. Solar activity can impact technology on Earth, including communication systems and power grids. Additionally, insights gained from studying the sun can help scientists understand fundamental processes that govern other stars and their atmospheres.
