#Astrinebr: a predatory galaxy in the universe

Jointly #ASTROMINİBRTecmundo Weekly brings together the most relevant astronomy news to keep the universe up -to -date. Take a look at this!

1. Cannibal Galaxy NGC 3640

Galaxy NGC 3640, which has 88 million light years from Earth, A real “cosmic predator”: Using images of the telescope of the Southern European Observatory (VLT), astronomers observed that NGC 3640 had a story of unification with other systems for billions of years and constantly absorbs smaller galaxies.

Recently, the Galaxy NGC 3641, which is about to be the next “dinner”, appears on a collision route.

The images also revealed that the NGC 3640 has deterioration in the forms of previous combines. This type of interaction between galaxies can deform the original structures and produce visible “scars” consisting of old stars.

These stars serve as fossil markers, reveal the turbulent history of the NGC 3640, and in time, it confirms that it absorbs other galaxies.

Although the NGC is approaching 3640 NGC 3641, there is no sign that the small galaxy is affected by the gravity of the larger neighbor’s gravity, which suggests that NGC 3641 may be longer before swallowing.

2. What is the sun wind?

The sun wind is a continuous flow of loaded particles, Protons and electrons extracted by the sun crown, the outer layer of the solar atmosphere. These particles progress in space at speeds that can reach 900 km/reaching along the solar system and create a dynamic environment around planets and celestial bodies.

The solar wind pressure can interact with the magnetic fields of planets such as Earth and may even affect the formation of Boreal and Austral Auroras. The extremely hot solar crown can ionize the gases in it and release the loaded particles for space.

For this reason, the sun wind is a manifestation of this activity, which is necessary to understand the physics of the sun and its interactions with the space environment. When the wind of the sun hits the world, it interacts with the magnetic field of the planet, which sees the surface of the world from harmful cosmic radiation.

Despite The sun wind has interesting and observable effects on our planetIt can also represent difficulties for space research. In long -distance tasks such as probes sent to the deep area, solar wind particles may affect the electronic systems and risk of astronauts of ships.

Continuous solar wind work helps scientists to improve the estimation of solar storms and better understand the phenomena in space and contribute to the protection of satellites and future space tasks.

3. Sulfuric acid as a component for life?

New research published by an international team directed by scientists from MIT suggests the following: In addition to water, foreign life can be connected to other fluids such as concentrated sulfuric acid.

According to the team, although water is an ideal solvent for life chemistry in the world, this can be a compound alternative on planets such as Venus, where the atmosphere is mainly made of sulfuric acid.

Research suggests that sulfuric acid can solve basic components for life such as amino acids and lipids without eliminating the molecules required for cellular processes. The study analyzed several items Methane can serve as solvent on other planets, including ammonia and even melted rocks..

A surprising result is that sulfuric acid can support complex biology, because many organic molecules can survive and react in this extremely acidic environment, which cannot be considered under terrestrial conditions. This discovery opens new possibilities for astrobiology, which suggests that life can develop radically in different ways.
