In this video, you will learn what black holes are, how they form and what types they are. Black holes are astronomical objects with an infinite density and a gravitational field so strong that nothing can escape them, not even light. They originate from the collapse of very massive stars, which explode in supernovae and leave a supercompact core. There are three main types of black holes: stellar, supermassive and intermediate, which vary according to their mass and size. You will also see the first photo of a black hole, taken in 2019, which shows its shadow and the disk of gas and dust that surrounds it. Black holes are fascinating and mysterious objects that help us better understand the universe and physics. Watch the video and discover more about these incredible features!

Dwarf planets are celestial bodies that orbit the Sun, but do not have enough mass to be the dominant ones in their regions. They also have rounded shapes due to their own gravity. In our solar system, there are five recognized dwarf planets: Ceres, Pluto, Haumea, Makemake and Eris. Ceres is the only one that lies in the asteroid belt, between Mars and Jupiter. The other four lie beyond Neptune, in the Kuiper belt, and are called plutoids. In this video, you will learn more about the characteristics, origins and curiosities of these small planets that are part of our solar family

The Milky Way is our galaxy, where the Solar System and planet Earth are located. It has a spiral shape, with four large arms that extend from a central bulge. In this bulge, there is a supermassive black hole called Sagittarius A*, which was photographed for the first time in 2022. The Milky Way is made up of billions of stars, planets, gases, dust and dark matter, which orbit its core at different speeds. The origin of the Milky Way coincides with the origin of the Universe, around 14 billion years ago, according to the Big Bang theory. The name Milky Way comes from its milky appearance, which can be seen in the night sky in places with little light pollution. In this video, you will learn more about the history, structure, formation and curiosities of our galaxy. Follow along!

Have you ever wondered what space sounds like? In this video, you will discover that the space is not as silent as it seems. You will hear the incredible sounds that can be captured by special instruments such as radio telescopes and space probes. You will be amazed by the sounds of planets, stars, black holes and even entire galaxies. You will learn how these sounds are converted into sound waves that we can listen to and enjoy. You will marvel at the beauty and diversity of sound in the space.

Stellar nebulae are large clouds of gas and dust that form in interstellar space, between stars. They can have different colors, shapes and sizes, depending on their composition, temperature and origin. Some nebulae are nurseries for new stars, while others are the remains of exploded stars. In this video, I will show you some examples of stellar nebulae, such as the Orion Nebula, the Carina Nebula and the Ring Nebula. You will also learn about the types of nebulae, such as emission, reflection, dark and planetary nebulae. Come with me on this journey through the universe of stellar nebulae and discover more about these cosmic wonders! 🌌

Did you know that meteors and shooting stars are different phenomena? In this video I explain some interesting facts about these celestial objects, such as what they are, where they come from, how they form and how we can observe them. Watch the video and discover more about the fascinating world of astronomy! 🌠

Have you ever wondered if there are other planets beyond our Solar System? These planets are called exoplanets, and they orbit stars other than the Sun. So far, more than 4000 exoplanets have been discovered by NASA, using different detection methods. Some of these exoplanets are similar to Earth, others are gas giants, and some are so strange that they defy our imagination. In this video, we will meet some of the most interesting and curious exoplanets, and learn how they can help us better understand our place in the universe. Come with us on this space adventure and discover exoplanets, the distant worlds that can hide incredible surprises!

Have you ever heard of supermassive black holes? They are the most extreme objects in the universe, with masses millions or billions of times greater than that of the Sun. They formed early in cosmic history, from gas clouds or clusters of stars that collapsed under their own gravity. They are at the center of almost all galaxies, including ours, and influence their evolution. They are so powerful that they can emit radiation, jets and winds that heat and expel the gas around them, preventing the formation of new stars. They can also attract matter to themselves, forming an accretion disk that glows brightly. They are responsible for phenomena called quasars, which are the most luminous objects in the universe. In this video, we will learn more about these mysterious giants and how astronomers manage to observe and study them. Don't miss this opportunity to learn about supermassive black holes, the kings of the cosmos!

Did you know that the Universe is expanding and that galaxies are moving away from each other? In this video, we'll explain how this happens and how we can measure the speed of galaxy moving away using the Doppler effect. Let's also talk about the consequences of the expansion of the Universe for cosmology and the future of the cosmos. Come with us on this journey through space and discover the mysteries of our Universe!

In today's video, we're going to talk about the accelerated expansion of the universe. This is a relatively recent discovery, made in 1998, and has important implications for our understanding of the universe. First, let's explain what expansion of the universe means. The universe is made up of an infinite number of galaxies, which are constantly moving away from each other. The speed of this expansion can be measured by observing the light from type Ia supernovae, which are star explosions that occur uniformly throughout the universe. In 1998, astronomers discovered that the expansion rate of the universe is not decreasing, as expected, but increasing. This means that the universe is expanding faster and faster. This discovery came as a surprise to scientists as there is no definitive explanation for it. The most accepted theory is that the accelerated expansion is caused by an exotic form of energy, called dark energy. This energy would have a negative density, which means it would cause an acceleration in the expansion of the universe. Dark energy is a mystery, and we still don't know much about it. However, it is one of the most important forces in the universe, and its existence has profound implications for our future. In this video, we will discuss the following topics: What is the expansion of the universe? How is the expansion of the universe measured? The discovery of the accelerated expansion of the universe The theory of dark energy I hope you enjoy the video! ​

Did you know that there are objects in the universe that are so dense that a teaspoon of them would weigh billions of tons? These objects are called neutron stars, and they are the remains of massive stars that exploded in supernovae. In this video, you will discover how neutron stars form, what their incredible characteristics are, and why they are so important to science and astronomy. You will be surprised by the wonders that space hides, and you will learn more about one of nature's most fascinating phenomena.
