TRACE and solar physics

The Transition Region and Coronal Explorer is a NASA Small Explorer (SMEX) mission to image the solar corona and transition region at high angular and temporal resolution. The goal of the TRACE science investigation is to deepen our understanding of the effects of the Sun's magnetic field on its own atmosphere, and to help us understand the changes that this causes in the heliosphere between Sun and Earth, and in the space around Earth, including our own atmosphere. TRACE is thus an important component of the Sun-Earth Connection theme of NASA. Click here for an introduction to the TRACE satellite and its scientific goals. The TRACE mission is described briefly here, and the instrument here. A paper model of the TRACE satellite can be made using this pdf file. Images and movies of a diverse collection of solar phenomena can be viewed here.

  • Have a look at an explanatory slide show that shows the solar surface and its outer layers, the environment between sun and Earth, the effects of the Sun on the Earth, and even the future fate of the Sun as it evolves. For something completely different, you can even listen to the sounds in the Sun that are generated by the turbulent motions of the gas near its surface, and read what that is used for in the field of helioseismology (1) to probe the internal structure of the Sun. There is also a K-3 lesson on the sounds of the Sun.
  • Among the vast amount of information that can be found on the web about the Sun in general, there are several brief introductions to the Sun There is a NASA educational site on the Sun including a picture of the sunspot cycle, and (links to) the solar corona and solar wind, and even an account of a flare observation by Carrington in 1859. Some diagrams, numbers, and more links forming another introduction to the Sun, and a collection of pictures and movies on a short tour about the Sun can also be explored. Australia's IPS Radio & Space Services developed an extensive set of pages containing links to a series of occasional articles by IPS staff and their colleagues on the Sun and its effects on the Earth. Or try this overview of the Sun, the solar system, and some of the nearby star systems.
  • The Stanford Solar Center presents a collection of fun educational activities where you can explore the Sun's tangled magnetic field, its turbulent surface motions, the dramatic sunspot cycle, and even what magic happens in the solar interior.
  • A large collection of pretty pictures of the Sun-Earth connection can be found at Goddard's ISTP outreach pages
  • There is also a collection of images of the solar eclipses of 24 October 1995 and 3 November, 1994, with ground-based eclipse movies, YOHKOH data, ...
  • The International Solar Terrestrial Physics (ISTP) Program WWW INDEX contains links to different sites related to the interaction of the Sun and the Earth.
  • The Space Studies Board of the National Research Council compiled this summary of the practical consequences of space weather. One particular example is a large-scale power outage caused by a solar eruption.
