Quotes

"With IRIS, we have a unique opportunity to provide significant missing pieces in our understanding of energy transport on the Sun. The complex processes and enormous contrasts of density, temperature and magnetic field within this interface region require instrument and modeling capabilities that are now finally within our reach."

IRIS Solar Satellite Arrives at Vandenberg AFB for Launch [Published Space Daily - Apr 19 2013]

"Although it is likely only a small effect, a temperature minimum region in other stars could result in us underestimating the amount of dust present in a cold debris disc surrounding it" says Dr. Liseau
