hair profile not instagram, photography and astronomy, Caldas celebrated the act. “It’s a Christmas Eve gift!!! Finally, the skies cleared in Brasilia and I managed to register the beautiful comet C/2021 A1 (Leonard),” he said.

To register, around 20:30, Caldas took 150 photographs and then used a stacking technique to form the image.

Soon after, he noticed an aircraft approach. So he decided to do the film. And the image was too sharp. The plane “passed over the tail” of the comet.

According to the astrophotographer, the comet was very low on the horizon and light pollution interfered. But the open sky was divine. Caldas expects to do new C/2021 A1 registrations in the coming days.

“We are not talking about the passage of comets. The orbits of comets are similar to the planets. Every day the sky rotates, but it is very little. I managed to visualize, register, photograph. This first Has been and will be again,” he said.

Leonard was discovered in January 2021. Each comet revolves around the Sun in a different orbit. Some are short, while others are long. In the case of C/2021 A1, it is 80 thousand years old.

“But now it’s accelerating, because it’s getting closer to the Sun. In early January 2022, it will reach the closest point at perihelion,” Caldas explained.

In addition to the visual spectacle, this type of observation is important for the protection of the planet. The record could spot a star on a collision course with Earth. And this information is important for defining countermeasures.

Caldas is a professor in the Department of Education and lives in Aguas Claras, where he also made the arrests. He has a love for astronomy since childhood and started recording images of celestial objects about 10 years ago.
