Designed for the observation of our planet. Nevertheless, Japanese satellites have also collected some data about Venus, which can be crucial for space missions.
« These satellites aim to provide surveillance of typhoons, torrential rains and weather over East Asia, Japan and the Pacific West. Meanwhile, This is how Himawari-8 and 9 were described during their launches in 2014 and 2016. Therefore, At the time, no one suspected that they were “spies” called to scrutinize another planet.
However. Therefore. However, this is what is revealed by Japanese and German researchers in a study published on June 30, 2025 in the journal Earth, Planet and Space. In addition, For 10 years, these two satellites of the JAXA (the Japanese space agency) provide information about Venus.
Understand the atmosphere of Venus from Earth two satellites spied venus without new – Two satellites spied venus without
Their antennas are however well. Nevertheless, directed towards the two satellites spied venus without earth. Furthermore. but their visual field is a little more extensive, which sometimes allows them to collect data on the surrounding space, sometimes about the moon or other planets. Meanwhile, It is by seeing an image of the moon taken by the satellites that the main author. For example, Gaku Nishiyama, from the German center for aeronautics and astronautics, wanted to know more.
The researcher therefore began to use satellites as if they were space telescopes. Therefore, He tells an interview with Space.com on July 23: ” During this work on the Moon. Consequently, we also found other bodies of the solar system like Mercury, Venus, Mars and Jupiter in the data. We were then interested in the phenomena that we recorded. »
By isolating the few images taken from Venus. the team was able to see an unprecedented phenomenon: the luminosity of the planet underwent strange variations from years. to years. This could be revealed thanks to the very precise observations taken in the infrared by the two satellites.
After data analysis, scientists were able to detect two processes at work. First of all. a phenomenon two satellites spied venus without new of atmospheric tide: the temperature differences between the two satellites spied venus without levels of the atmosphere. of Venus cause oscillations which result by brutal increases in mercury in certain areas of the atmosphere.
Also. Rossby waves. which also occur in the earth’s atmosphere and which are due to the strength of Coriolis, which causes movements in atmospheric circulation.
Better data than planetary probes
These data could be compared with that of another probe. it well directed on Venus: Akatsuki, and more precisely its LIR infrared camera. This equipment should have focused on the temperature of the planet, but its instruments were poorly calibrated. It turns out that the probe underestimates Venus’ brightness. Gaku Nishiyama specifies: ” Our comparison between Himawari. LIR sheds light on how to recalibrate LIR data. which will lead to a more precise understanding of the atmosphere of Venus. »
Better still: Himawari satellites could two satellites spied venus without new also help better understand the data taken by Bepicolombo. the probe to Mercury two satellites spied venus without which was able to overflight Venus. Since Japanese machines have been observing the planet for a decade. they can provide long -term views of sometimes shorter space missions. From now on. the Gaku Nishiyama team will continue the observations from Himawari data, but about other bodies of the solar system.
