The Earth
is one of nine planets orbiting the Sun, and the Sun is
one of some 100 billion stars that make up the Milky Way
galaxy. The Milky Way and about 30 other galaxies comprise
the Local Group, which in turn is part of the local supercluster
of galaxies. Superclusters seem to be grouped into even
larger systems, all of which fit within the visible Universe.

- ACE
Real Time Solar Wind Information Geomagnetic storms
are a natural hazard, like hurricanes and tsunamis, which
the National Oceanic and Atmospheric Administration (NOAA)
Space Environment Center (SEC) forecasts for the public's
benefit. Severe geomagnetic storms cause communications
problems, abruptly increase drag on spacecraft, and can
cause electric utility blackouts over a wide area. The location
of ACE at the L1 libration point between the earth and the
sun will enable ACE to give about a one hour advance warning
of impending geomagnetic activity.
- Cosmic
and Heliospheric Learning Center The Cosmic and
Heliospheric Learning Center, brought to you by the cosmic
ray group at NASA GSFC, is designed to increase your interest
in cosmic and heliospheric science. (The heliosphere is
the HUGE area in space affected by the Sun.) It's an exciting
subject to learn about and is a robust area of study.
- Eyes
on the Skies Robotic Solar Telescope This is the
home of the internet-accessible robotic solar telescope,
built by Tri-Valley Stargazers member, Mike Rushford. Yes
you can control your H-alpha filtered view of the sun by
controlling this telescope from your web browser on sunny
days in Livermore California, USA. At other times there
are other things to do too! Read about the latest solar
physics findings a the Stanford Solar Center. and the Sunspots
and the Solar Cycle site.
- Our
Sun The sun is an average star with a mass equal
to nearly one-third of a million Earths. Learn about the
Sun here.
- SOHO
Exploring the Sun The SOHO project is being carried
out by the European Space Agency (ESA) and the US National
Aeronautics and Space Administration (NASA) as a cooperative
effort between the two agencies in the framework of the
Solar Terrestrial Science Program (STSP) comprising SOHO
and CLUSTER, and the International Solar-Terrestrial Physics
Program (ISTP), with Geotail (ISAS-Japan), Wind, and Polar.
- Spectrohelioscope
This web page is presented for those who have an interest
in the spectrohelioscope and perhaps the desire to build
one of these interesting instruments. George Ellery Hale
(1868-1938) invented the spectrohelioscope in 1924 which
allowed detection of sudden outbursts of activity on the
sun. The following photographs are of such an instrument,
built by Leonard Higgins with the support, and guidance
of Fredrick Veio, author of the book, "The Spectrohelioscope."
This particular instrument has been on display at the RTMC
(Riverside Telescope Maker's Conference) at Big Bear Lake,
Camp Oaks in California, U.S.A., for the last two conferences,
1998 and 1999. It received a Merit award at the RTMC , 1998.
- The
SSP Monitor This site has everything you would ever
want to know about Solar Power and more.
- Sunspots
and the Solar Cycle Planning for satellite orbits
and space missions often require advance knowledge of solar
activity levels. NASA scientists are using new techniques
to predict sunspot maxima years in advance. Click here for
the latest predictions for the current solar cycle.
- Transition
Region and Coronal Explorer 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 TRACE project maintains
an Open Data Policy: all data are available from our data
archives to the science community as soon as the spacecraft
data have been processed.
- Ulysses
Solar Exploration at High Latitudes over the Sun's Poles
The Ulysses Mission is the first spacecraft to explore interplanetary
space at high solar latitudes. Ulysses is a joint endeavor
of the European Space Agency (ESA) and the National Aeronautics
and Space Administration (NASA) of the USA. The spacecraft
and spacecraft operations team are provided by ESA, the
launch of the spacecraft, radio tracking, and data management
operations are provided by NASA. Scientific experiments
are provided by investigation teams both in Europe and the
USA.
- YPOP
Solar Classroom The YPOP Solar Classroom is filled
with hands-on, solar related activities. There is something
for everyone. Many of these activities teach you about the
Sun itself. Others teach a physical concept, like rotation,
using the Sun as an example. We invite teachers, students,
parents and children of all ages to experiment with the
activities below. Enjoy!
