The planet closest to Earth is Venus. We can explore Venus, and we have sent multiple spacecraft to study its atmosphere and surface. However, its extreme temperatures, atmospheric pressure, and acidic environment make it challenging for human exploration.
The Galileo probe flew by Venus in 1990 on its way to Jupiter. It used the gravitational pull of Venus to adjust its trajectory for the journey to Jupiter, where it arrived in 1995 to study the planet and its moons.
Some of the satellites that have been sent to Venus include Magellan in 1989, Venus Express in 2005, and Akatsuki in 2010. These missions were launched to study Venus' atmosphere, surface, and geology.
The ESA satellite "Venus Express" was launched on November 9, 2005 and began orbiting Venus on April 11, 2006.
As of now, the Akatsuki spacecraft, which is a Japanese probe, is currently orbiting Venus. It is studying the atmosphere and weather patterns of Venus. Other past missions, such as the Magellan spacecraft, have also orbited Venus to study its surface features.
what are instruments or technology are used to study active volcanoes?How do these tools work?Which are used when the volcano is quiet or dormant?
There is no life as we know it on Venus. The only technology there is what we sent to Venus in the various probes sent from Earth.

to study venus...lol!
From Earth we can do it using telescopes and other technology. A number of probes have been sent to Venus. Some just orbited it and some landed on it and sent back information, including video.
Satellite technology is used to study planets and to watch television.
to study venus...lol!
This was to investigatethe atmosphere of Venus.

The Magellan probe was designed to study Venus. It went to Venus in 1994.
That would be Oceanography I believe.
