Launched in December 1995, the joint NASA-ESA Solar & Heliospheric Observatory mission — SOHO — was designed to study the Sun inside out, from its internal structure, to the extensive outer atmosphere, to the solar wind that it blows across the solar system.
What is SOHO and how is it monitoring the sun?
The Solar and Heliospheric Observatory (SOHO) is a spacecraft built by a European industrial consortium led by Matra Marconi Space (now Airbus Defence and Space) that was launched on a Lockheed Martin Atlas II AS launch vehicle on December 2, 1995, to study the Sun. It has also discovered over 4,000 comets.
What does the SOHO satellite do?
SOHO stands for Solar and Heliospheric Observatory and is a satellite that studies the Sun 24 hours a day, 365 days a year without interruptions. The spacecraft has 12 scientific instruments collecting information about the Sun ranging from activity in the Sun’s corona to vibrations deep in the Sun’s interior.

Is the Soho closer to sun or Earth?
The Sun Today: Solar Facts and Space Weather SOHO is 1,500,000 km (~930,000 mi) away from the Earth. The moon is 384,000 km (~239,000 mi) away from the Earth. The Sun is 150,000,000 km (~93,000,000 mi) from the Earth.
What is the primary function of the SoHo?
SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind.
What did SoHo find?
According to ESA, its chief discoveries include finding complicated gas currents below the sun’s visible surface, as well as tracking frequent changes in magnetic fields. Researchers came close to losing the spacecraft in June 1998, less than three years after launch, after a routine gyroscope calibration.
What did SOHO discover about the sun?
Over those two decades in space, SOHO has made many new discoveries, adding to scientists’ understanding of our closest star. SOHO has revealed the first images ever of the Sun’s convection zone — its turbulent upper layer of the interior — and of the structure of sunspots below the surface.
Is the SOHO closer to sun or Earth?
Is SoHo in London or New York?
Soho is an area of the City of Westminster, part of the West End of London. Originally a fashionable district for the aristocracy, it has been one of the main entertainment districts in the capital since the 19th century.
How does Soho take pictures of the Sun?
Daily image of the sun in 304 wavelength as seen by SOHO (60,000-80,000 degrees Kelvin). LASCO is able to take images of the solar corona by blocking the light coming directly from the sun with an occulter disk, creating an artificial eclipse within the instrument itself.
What is the SOHO spacecraft?
The Solar and Heliospheric Observatory (SOHO) spacecraft is the great solar observatory orbiting the Sun. A joint mission between NASA and ESA (the European Space Agency), SOHO’s 12 instruments capture images of the Sun in a variety of “colors”, from visible white light to the extreme ultraviolet.
What can I find on the Soho homepage?
On the SOHO homepage you can find breaking news, hot shots of awesome current phenomena, a Weekly Pick image, and special features. A current image of the Sun taken in “white,” or visible, light.
How long did Soho last?
Happy Birthday SOHO! We are celebrating 25 years since the launch of SOHO… Two and a half decades of scientific discovery is a major milestone for any space mission. But when the spacecraft at the heart of the celebration was only designed to last for two years,..
