Observations in this part of the spectrum had to await the 'space era', with rocket launchers that could carry X-ray telescopes above the Earth's atmosphere, opaque to this type of radiation. But the wait was worth it: the history of this discipline features pioneering technology and spectacular discoveries about cosmic objects near and far, with ESA playing an increasingly major role over the past 35 years.

| | | | | Earth likely passed through "a fold in theheliospheric current sheet," which induced a powerful electrical surge down here on the ground. While science news is filled with rumbling earthquakes and rippling gravitational waves, a different kind of perturbation was felt in Norway yesterday (Jan. 6)-but its cause is a little mysterious. "Electrical currents started flowing,"... | |

| | | Before the discovery of the first exoplanet that orbits a star like ours, 51 Pegasi b, the assumption of solar system scientists was that others planetary systems that might exist were likely to be like ours. Small rocky planets in the inner solar system, big gas giants like Jupiter, Saturn and Neptune beyond and, back... | ||
