Supernova twins: Making standard candles more standard than ever
Berkeley CA (SPX) Nov 06, 2015
Less than 20 years ago the world learned that the universe is expanding ever faster, propelled by dark energy. The discovery was made possible by Type Ia supernovae; extraordinarily bright and remarkably similar in brightness, they serve as "standard candles" essential for probing the universe's history. In fact, Type Ia supernovae are far from standard. Intervening dust can redden and dim them, and the physics of their thermonuclear explosions differs - a single white dwarf (an Earth-sized star a ... read more
