#AstroMiniBR: What are the chances of an asteroid colliding with Earth?

#AstroMiniBR and TecMundo meet each week to share with you five relevant and unusual astronomical curiosities produced by collaborators From the profile on TwitterTo spread knowledge about Astronomy, one of the oldest and most fascinating sciences in the universe. Check out the week’s trivia below!

#1: What is the risk of a large asteroid hitting Earth?

With the development of celestial observation technologies, astronomers constantly identify celestial bodies in the sky. potentially dangerous asteroids: space rocks that could represent a possible risk of collision with our planet.

These asteroids are rocky or metallic bodies of varying sizes and masses that orbit the Sun and are likely to pass through Earth’s orbit, causing significant damage upon impact.

While it is impossible to predict with absolute accuracy when and where a large asteroid might collide with Earth, continuous monitoring of the sky and orbital studies The number of large objects close to Earth indicates that the probability of a large-scale impact event is low for short periods, but some significant events may occur in the long run.

Such analyzes are fundamental to the development of mitigation strategies and reflect the importance of researching and continuous monitoring of asteroids for the safety of our planet.

#2: An extremely hot gas!

In galaxy clusters, the intergalactic space filled by various components is called the intra-cluster medium. including gas, dust and dark matter.

The gas in the cluster environment consists mainly of hydrogen and helium, but also contains traces of heavier elements. This gas is characterized by extremely thin, very low densities, but extending over large intergalactic distances.

However, the most striking physical feature of intra-cluster gas is its extreme temperatures, which can reach hundreds of millions of degrees Celsius. making these regions one of the hottest regions in the entire Universe!

These very high temperatures are caused by various heating processes, such as gravitational interaction between galaxies, the formation of shock structures, and the emission of radiation by supermassive black holes at the center of galaxies!

#3: Conjunctions in the winter sky!

Astronomical conjunctions are notable events that occur when two or more celestial bodies approach each other in the sky. Them Cosmic encounters can include planets, moons, stars, and even galaxies.It offers a unique celestial spectacle to Earth watchers.

Conjunctions can vary in nature and size, from planetary conjunctions visible to the naked eye to rarer events such as planetary conjunctions with bright stars. The image you see like this is a good example planetary conjunction between Venus and Mars with the presence of bonus star Regulus! Look at the sky!

#4: A cosmic jet!

Located about 2.5 billion light-years away in the constellation Virgo and cataloged as 3C 273, the object is one of the brightest quasars ever observed, visible even with amateur telescopes. Its uniqueness lies in its extremely active nature. emits an enormous amount of energy equivalent to hundreds of galaxies.

With the help of spectroscopic studies, scientists have powered by a supermassive black hole Its mass is estimated at 900 million times that of the Sun. By analyzing its radiation, astronomers have the opportunity to study the properties of the oldest structures in the universe and how they evolved over time.

#5: James Webb and the Pillars of Creation

Located in the Eagle Nebula, about 7,000 light-years from Earth, One of the most beautiful structures known in the Cosmos is the Pillars of Creation.. These pillars are cosmic structures of gas and dust stretching light years into space.

Their majestic and majestic appearance is the result of the intense star-forming activity occurring within them, serving as home for stars formed from the gravitational collapse of the surrounding material. Recent research has revealed that these pillars were shaped by intense radiation from nearby young stars that shaped these complex and dramatic shapes over millions of years.
