NASA launches telescope the hunt for hazardous asteroids
If everything runs as planned, the WISE telescope will be sent into space on December 9. The goal of WISE is to scan in infrared light across the sky to find asteroids and meteors that may be hazardous to Earth. “We will find thousands of objects never before seen,” warned Edward “Ned” Wright, the mission’s [...]

Dark matter still too dark
On December 17, 2009, the world of astrophysics was holding its breath: the rumored for several days that the collaboration CDMS (Cryogenic Dark Matter Search), which seeks to reveal the ghostly dark matter detectors with germanium / silicon mat in a mine Rockies, had succeeded. The long-awaited announcement was ‘pfuit’ like a damp squib: two [...]
A solar sail demonstrator called IKAROS
The Japanese spacecraft PLANET-C Venus will be joined at its launch in May 2010 on an H-IIA rocket by a prototype solar sail called Ikaros (Interplanetary Kite-craft Accelerated by Radiation of the Sun). This project is like PLANET-C, developed by the Scientific Section (ISAS) of Japan Aerospace Exploration Agency (JAXA).
ISAS is not his first [...]

Civilization astronomy was dominated
Since the beginning of civilization astronomy was dominated by the study of the motions of celestial bodies. This work was essential for astrology, for the determination of the calendar, and for the prediction of eclipses. The connection between the calendar and the motions of celestial bodies is most important because it meant that astronomy was [...]
History of Radio Astronomy
Radio astronomy is the study of the Universe using radio waves, usually using electromagnetic radiation with wavelengths from the microwave band (a couple of centimeters) and upwards. Radio astronomy plays a key role in investigating the Universe.
The words “radio astronomy” were first used in the 1940s to describe the new method of studying the universe [...]
Radio Astronomy Works
When radio waves reach the earth they are extremely weak. Therefore a reflector must be shaped to reflect all the waves to a point. At this point an antenna receives the waves and sends them to a powerful short-wave radio receiver. Reflectors are usually concave and follow the same curvature as do the mirrors of [...]
