Jessica’s Reviews > Stars Without Number: Revised Edition > Status Update

The only thing I object to for any content in this book is about the Fuel Scoops starship “fitting” - there is no such thing as a stellar “penumbra”. Penumbra refers to a partial shadow cast during an eclipse and thus cannot be used for fuel. If the author meant the stellar *corona*, fuel harvesting would have to be done carefully, because the Sun’s corona at least has a temp of over 1 million degrees F.
