We're so used murder mysteries that we don't even notice how mystery authors play with time. Typically the murder occurs well before the midpoint of the book, but there is an information blackout at that point and the reader learns what happened then only on the last page.

The answer, so o ... read more

The mystery of cosmic oceans and dunes Simulations by researchers at Tokyo Institute of Technology and Tsinghua University indicate that Earth-like planets are more likely to be found orbiting Sun-like stars rather than lower-mass stars ... more		Dark matter guides growth of supermassive black holes Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and le ... more		Why do starburst galaxies 'burst'? Starburst galaxies transmute gas into new stars at a dizzying pace - up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while othe ... more
				With new data, Planck satellite brings early universe into focus From its orbit 930,000 miles above Earth, the Planck space telescope spent more than four years detecting the oldest light in the universe, called the cosmic microwave background.
