Zoom-up star photos poke holes in century-old astronomical theory
(PhysOrg.com) -- The hottest stars in the universe spin so fast that they get a bit squished at their poles and dimmer around their middle. The 90-year-old theory that predicts the extent of this "gravity ...
How the sun gets its spots
Sunspots are huge, dark, irregularly shaped--and yet, temporary--areas of intense magnetism on the sun that expand and contract as they move.
Are you ready to retire? Mathematical models estimate the value of pension plans
There comes a time in each of our lives when we consider starting a pension plan –either on the advice of a friend, a relative, or of our own volition. The plan of choice may depend on various factors, ...
Physics professor publishes exact solution to model Big Bang and quark gluon plasma
