First images released of the Sun

The European Space Agency (ESA) has today released the first images of the Sun taken by its Solar Orbiter.

This is the closest any camera has ever been to the Sun, with the satellite just 77 million km away from it when the photographs were taken — about half the distance between Earth and the star.

“It’s as if the spacecraft had sent us a postcard from its journey,” said Daniel Müller, Solar Orbiter Project Scientist at ESA.

The satellite was launched on February 10, 2020, and made its first up-close approach to the Sun in mid-June.

In the lead up to the big reveal, Müller said: "The first images are exceeding our expectations.”

“We can already see hints of very interesting phenomena that we have not been able to observe in detail before," he added.

"The 10 instruments onboard Solar Orbiter work beautifully, and together provide a holistic view of the Sun and the solar wind.

"This makes us confident that Solar Orbiter will help us answer profound open questions about the Sun.”

The Solar Orbiter has six telescopes that capture images of the Sun and four situ instruments, which monitor the environment around the spacecraft.

Data from both instruments enables the scientists behind the mission to study the solar wind (the stream of charged particles from the Sun) and how this influences the entire Solar System.

The images seen today are the result of technical tests known as "commissioning" to ensure all parts of the spacecraft are working. Scientists say that as the Solar Orbiter gets closer to the Sun, the images will become sharper.
