Vera Rubin and W. Kent Ford’s 1970 Andromeda survey mapped how orbital speed changes with radius. Outer stars move too fast for the visible mass alone. Whether that means dark...

Gravity bends light because spacetime is curved. The 1919 eclipse measured the Sun’s deflection; Einstein’s 1936 note foresaw stellar lenses; modern telescopes image Einstein rings. Here is the physics without...

Did Cecilia Payne Discover What Stars Are Made Of?
Cecilia Payne’s 1925 thesis showed that stars differ mainly in temperature, not composition, and that hydrogen and helium vastly outnumber everything else. She then called that result “almost certainly not...

Every direction you look, the sky glows faintly in microwaves at 2.725 kelvin. That glow is light released about 380,000 years after the Big Bang. Here is how it formed,...
