class of shorter-lived GRBs is still a mystery, but that's another story. The first waves of star formation after the Big Bang should have produced plenty of metal-poor...
improbably thin. If you made a 1-meter-wide scale model of Saturn, the rings would be 10,000 times thinner than a razor blade. They're full of strange waves and spokes and...
. [larger image] Could it be that sunspots are not rooted to the bottom of the Conveyor Belt, after all? "That's one possibility" he notes. "Sunspots could be moving because...
observations are needed to decide its ultimate success or failure." Tappe is doing his part with a new round of Spitzer observations: "We're mapping the distribution of PAHs...
State University in Raleigh, who led the Chandra study. "Fortunately, the expanding gas cloud from the explosion shines brightly in radio waves and X-rays for thousands of...
. Questions about effects on climate are natural if the sun continues to dim." Pesnell is NASA's project scientist for the Solar Dynamics Observatory (SDO), a new spacecraft...
from one rotational energy state to another, they emit radio waves at precise frequencies. The "family" of radio frequencies emitted by a particular molecule forms a unique "...
atmosphere they heat and ionize the air in their path. The luminous ionized trails are not only visually striking (if seen at night) but they also reflect radio waves. During...
objects that emitted radio waves with clock-like precision. Left: A sky map showing the approximate location of this discovery (J1946+274). The pulsar and its...
material is pure and undisturbed. Measuring how viscosity ("You squeeze the metal and watch how the waves damp out") and surface tension (the same effect that lets bugs walk...
