#AstroMiniBR: Cosmic dance of galaxies in the universe!

‘Oh, make way, the galaxy block will pass’. TecMundo and AstroMiniBR collaborators in a carnival atmosphere In profile at Xhas brought together the most extraordinary astronomical curiosities to share with you. Check out!

#1: A galactic ball!

Interactions between galaxies are extremely important cosmic events that shape the evolution of the universe. These encounters occur due to the mutual gravitational attraction between these cosmic islands, leading to numerous morphological and physical consequences for each.

For example, when two galaxies come close to each other, their intense gravitational forces cause distortions in their original shape and can lead to mergers that form an entirely new galaxy. During these processes, individual stars rarely collide due to the large distances between them, but gravitational forces shape the orbits and distributions of matter and also change the internal structure of both galaxies involved.

In addition to changes in galactic formats, interactions often trigger intense star formation activity, This is because interstellar gas is being compressed, triggering the formation of new stars at faster than average rates.

Galactic mergers can also result in the formation of supermassive black holes at the combined centers of galaxies and, in addition, can release enormous amounts of energy in the form of gravitational waves, contributing to the complex cosmic dance that defines the planet’s evolutionary trajectory. large-scale structures Universe.

#2: Have you ever heard of cinematic lighting?

The dark light of the moon, is a fascinating phenomenon also known as black glow This adds a magical dimension to the night view that is so common and ordinary for humanity.

Unlike the direct sunlight that illuminates the Earth during the day, the Moon’s red light is the result of sunlight reflecting from the Earth onto the Moon’s surface. As the Moon waxes or wanes, some of the light reaching the Earth is reflected back to our natural satellite in a process known as Earth illumination, creating a faint, soft illumination on the part of the Moon that is not directly illuminated.

The cinematic light of the moon provides a spectacle that has inspired artists, poets and scientists for centuries. Highlights the inherent beauty of the optical interconnection between Earth, Moon and Sun.

#3: 20 years of robotic duo on Mars

Opportunity and Spirit rovers launched by NASA in 2003 It represented important milestones in the exploration of MarsIt opens new windows to understanding our planetary neighbour.

Designed for short-term missions, these robotic vehicles exceeded all expectations by operating for years in harsh conditions. For example, the Spirit rover landed in Gusev Crater and explored the vast Martian plains for more than six years, contributing significantly to our understanding of Martian geology.

After landing in Meridiani Planum, Opportunity discovered evidence dating back billions of years. Mars may harbor liquid water on its surface, raising intriguing questions about the possibility of past life on the Red Planet.

These tireless robotic explorers turned the originally planned mission into an incredible saga of exploration, paving the way for future discoveries and cementing their place in the history of space exploration.
