The Solar and Heliospheric Observatory (SOHO) spotted an unusual object identified as a triple comet flying past the Sun in early August. Although the satellite captures comets all the time– most of which are Kreutz sungrazers– the particular object is not a…
A citizen scientist from Europe discovered SOHO's 4 000th comet in the spacecraft's 25-year history. SOHO — Solar and Heliospheric Observatory — jointly operated by NASA and ESA since 1995. The comet was discovered on June 15, 2020, and is currently…
Today marks the 20th anniversary of NASA/ESA Solar and Heliospheric Observatory (SOHO). Originally planned for two-year mission, the project has now almost gone strong for two full solar-cycles, making the project longest Sun watching satellite to this day. When…
The Solar and Heliospheric Observatory (SOHO) detected its 3000th comet on September 13, 2015. The newest discovery confirmed SOHO's reputation for being the greatest comet finder in the history so far.SOHO is a joint project of the European Space Agency and NASA on
Just as we all accepted that the Comet ISON has most likely disintegrated under the high heat and gravitational stress of the Sun, amazing sungrazer came ALIVE, gaining more brightness. Thousands watched ISON's journey through the solar system and its unusual
On November 28, 2013 at 18:44 UTC Comet ISON will reach its perihelion and fly by about 1.2 million km (730 000 miles) above the solar surface. Since space-based solar observatories will be recording its passage just follow the links and timetable below for
SOHO's latest "Picture of the week" edition released great graphic illustration of combination of Sun-observing spacecrafts coverage of solar events.
From their positions near the Sun-Earth line, SDO and SOHO observed small CME on July 4, 2013. At
Strong solar flare erupted on May 9, 2013 at 22:52 with peak at 23:15 UTC as C9.1 flare, just below M-class threshold. The event was centered around old returning Sunspot 1726. It will be on the visible solar disk in the next 24 hours when it will be designated as
On May 1, 2013, Active Region just around the left edge of the Sun erupted with a huge coronal mass ejection (CME). The video bellow shows combined imagery from NASA’s SDO, SOHO and STEREO heliophysics fleet.
Solar Dynamics Observatory (SDO) provided a
Comet ISON is on a journey through our solar system that will culminate in its close encounter with the Sun on November 28, 2013. At that time the comet will pass at a distance of only 2.7 solar radii from the Suns center.
Comet C/2012 S1, named ISON, was
