Invisible nature within reach of the human eye

The Science Park, in collaboration with the University of Granada, opened on Tuesday its new temporary exhibition: “Invisible. Intangible Nature”. This exhibition uses the latest technologies to allow visitors to explore a reality that was impossible to photograph. To the human eye.

“Invisible” brings us closer to unimaginable places. Curiosity is the driving force that drives humans to develop increasingly sophisticated technologies, through which they can glimpse the limits of the impossible. Observing the microscopic structure of a butterfly’s wing or learning the composition of dark matter is already a reality.

During the opening ceremony, Luis Alcalá, Director of the Science Park, highlighted the importance of transferring this knowledge to society, in addition to highlighting the fundamental role played by the University of Granada.

The opening was also attended by Isabel Sánchez, researcher at the Scientific Instrumentation Center, and Sergio Navas, Vice-Rector for Research and Transformation at the University of Granada. Isabel emphasized that through these images they were able to disseminate science to the entire public. “The Science Park is an ideal platform for that,” she added.

In addition, he stressed that you can only find this exhibition in Granada, although some of the photos have already traveled throughout Spain after winning the National Scientific Photography Competition for five consecutive years.

“To detect small things we need very large devices and we are able to do that,” said Sergio Navas. During the event, he was surrounded by the first visitors who listened attentively to explanations about the Antares Neutrino Telescope that will from now on be found in the Science Park.

Technology used

Antares is a neutrino telescope consisting of a three-dimensional network of highly sensitive optical receivers located 2,500 metres below sea level and distributed over 12 cables 450 metres high. The Antares experiment was implemented in 2008, 40 kilometres off the coast of Toulon in Marseille. This telescope is designed to receive evidence and signals from the light energy emitted by neutrinos – tiny particles.

Computed axial tomography (CAT) is a diagnostic test that is widely used in the clinical setting because it produces radiographic images of the inside of the body, which can be converted into three-dimensional images.

A scanning electron microscope (SEM) is a device that allows objects to be seen on a very small scale. It uses electron beams to ensure high-resolution images.

The environmental scanning electron microscope (ESEM) is a type that can operate in low-vacuum environments, eliminating the need for special sample preparation.

To create these works they combined science, art and research. “We create images to which we add colour, but without changing reality. This way we get more public attention,” said Isabel.

Before ending the show, Isabel invited the audience to use their imagination because “nothing is as it seems.” The first visitors were satisfied with the exhibition. They declared: “We like everything, but what we like most are activities that make us think.”

The exhibition will be open to the public until the end of 2024, in the Milky Way Pavilion. It can be visited from Monday to Saturday from 10:30 am to 6:30 pm, and on Sunday from 10:30 am to 2:30 pm.
