Title: Cheap Astronomy – Dear CA #99: Same Old
Organization: Cheap Astronomy

Description: Cheap Astronomy looks at some new ways to answer some old questions.
Dear Cheap Astronomy – I still don’t get Lagrange points, particularly L4 and L5.
Most explanations of Lagrange points are a bit idealised. For example, explanatory diagrams show Earth’s orbit as a perfect circle around the Sun, which isn’t right, it’s really an ellipse.
Dear Cheap Astronomy – Can neutrinos predict supernova explosions?
We’ve previously expressed doubts that the recent dimming of Betelguese suggests it is about to go supernova. Since Betelguese is an irregularly variable star, the recent dimming just means it’s being true to form.
Bio: Cheap Astronomy offers an educational website where you’re only as cheap as the telescope you’re looking through.
