Every week, TecMundo and #AstroMiniBR bring together the most interesting astronomical curiosities produced by the team’s collaborators. Twitter profile To spread astronomy knowledge. See below!
#1: An unwanted web of light in the sky!
What you see in the images below are not the bright traces of a meteor shower; traces of the passage of artificial satellites. These tools have revolutionized human life in a way unprecedented in history, including astronomy, by providing a unique perspective on the universe and rapidly sharing data among the scientific community.
However, this technological achievement has also brought significant challenges to astronomical observations, and lately these challenges have been increasing. The increased light pollution created in the sky by the passage of these satellites and the electromagnetic interference caused by devices operating at frequencies similar to those used in astronomy negatively affect terrestrial observations.
The global scientific community is constantly seeking solutions to mitigate these negative impacts, such as international cooperation to develop standards and regulations that guarantee the preservation of the quality of the sky for astronomical observations.
But this is a problem that does not affect observations made by space missions such as the Hubble and James Webb telescopes, which operate in orbits relatively far from other satellites.
#2: An astronomical observatory on Brazilian soil
No, the image you see below was not taken at a remote observatory in Chile. This beautiful photo was taken at the Pico dos Dias Observatory (OPD), a famous astronomy research center located in the mountains of Minas Gerais, Brazil..
Founded in 1980, OPD enjoys a privileged location at approximately 1,860 meters above sea level; This positions it above many atmospheric contaminants and allows for exceptionally clear stargazing.
Equipped with several advanced telescopes, including the 60 cm Zeiss Telescope, OPD plays a fundamental role in Brazilian and international astronomy research. It is also an active observatory in scientific dissemination, promoting public education, and inspiring future generations of astronomers.
With ongoing expansion and modernization plans, OPD is poised to play an even more important role in global astronomy research. The continued application of new, advanced tools will allow scientists to explore the Solar System and other corners of the Universe in deeper, more detailed ways.
#3: 4 interesting facts about our moon
Everyone knows that the moon is not made of cheese bread. But did you know that it was formed after a collision with the Earth billions of years ago? Currently, the most accepted theory of the formation of the Moon is the “great impact” theory: Just over 4 billion years ago, a Mars-sized object first collided with the Earth, a collision so violent that it ejected debris from the Earth. We create our natural satellite to the Earth, to space.
including the moon, It ranks fifth among the largest moons in the Solar System, after Jupiter’s two moons, Ganymede and Callisto, and Saturn’s two moons, Titan and Rhea.. What we call the hidden face of the Moon is due to the fact that it always shows us the same face; this is a phenomenon resulting from its synchronous rotation with the Earth: the Earth’s gravitational pull has gradually slowed the moon’s rotation over time. It is aligned with the orbital period.
Finally, a fact well known to the public is that the Moon has a strong influence on the Earth, causing the movement of ocean tides. The Moon’s gravitational pull causes two sea rises to form on opposite sides of the planet, one facing the Moon and the other on the opposite side.
As the Earth rotates beneath the Moon, tides ebb and flow, creating the tidal cycle we experience every day. This impact not only shaped coastal landscapes, but also played an important role in the evolution of marine life throughout Earth history.
