... We combine spatially and temporally multi-instrument observations obtained simultaneously with the SUMER spectrometer onboard SoHO, EIS and XRT onboard Hinode, and EUVI/SECCHI onboard the Ahead and Behind STEREO spacecrafts. ...
... The aim of the exhibition is to show the wonderful variety of images of the Sun provided by modern spacecraft, and to illustrate how dependent we are on our nearest star, which is surprisingly and highly variable. ...
... They make observations of the Sun using spacecraft and ground-based telescopes to investigate solar flares, sunspots and jet-like structures in the SunтАЩs atmosphere. ...
... astronomy is a relatively new branch of astronomy, growing rapidly in recent years following the launch of the HIPPARCOS spacecraft, which accurately measured the positions of over 100,000 stars from 1989 to 1993, and because of the availability of ...
... These models will be combined with precise atomic data in order to calculate the amount of light emitted, so as to compare the result with observations of the Sun from spacecraft like SOHO and TRACE , and to improve the model. ...
... ESA spacecraft were sent to the Moon, Venus, Mars, and a probe put down on Titan. €аIn a couple of years a European lander will land on a comet nucleus. €аBeyond that comes a mission to Mercury. €аAt the same time, European missions like Herschel and ...
... The spacecraft, which weigh about 1,485 pounds when fully fuelled, are in orbits tilted 86.4 degrees to the equator at an altitude of about 485 miles. ...
