This week we are pleased to welcome Dr. Merav Opher, Professor from the Astronomy Department of Boston University and the Director of the SHIELD (Solar wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) DRIVE Science Center.

However, in a paper published in March, 2020, in Nature Astronomy, Dr. Opher (as lead author) and the team from SHIELD predict an alternative shape for the heliosphere: one that does not include this tail, but rather resembles a “deflated croissant.”
