Fenómenos, all those manifestations that do not occur daily, but that in a natural and spatial way, can be perceived by man from Earth or through quite advanced telescopic equipment. The word phenomenon is of Latin origin “phaenomenon”. This article will specifically mention the phenomena that have to do with some lights or "fires" that are visible in the sky, from Earth.
There are infinities of phenomena, many of them cannot be appreciated frequently and even, they may not even be seen by man. There are many unknown and unknown phenomena. However, some of the most spectacular sightings that have been witnessed, even by any amateur. Among them, we can mention: comets, meteor showers and fireballs.
These last, the racing cars, are mineral masses in ignition that come from the disintegration of asteroids or the fragmentation of some comet. These quickly pass through the atmosphere and often burst into pieces causing falling meteorites or fragments. Together with comets and meteors, they are the most seen. However, other sightings also fit into this category.
Such sightings, because of the space exploration has been investigated that orbit the planet Earth. There are innumerable objects that human beings have put there, and sometimes we are lucky enough to observe them from solid ground. In this article it is necessary to mention all the space phenomena that have been the most prominent so far.
There are several mysteries that are going to be mentioned, which include the phenomena that can be seen from our planet Earth and also the most outstanding phenomena that, although they cannot be seen with the naked eye, we can know about them thanks to the excellent ones telescopic equipment created by NASA and all kinds of astronomical scientists.
These are the four space phenomena seen from Earth
Rather than think about UFOs or aliens, we mustn't lose sight of the spatial phenomena that already exist in the Universe. There are many objects and spatial phenomena that have been identified but are still completely incomprehensible to humans. From the planets in our solar system to massive explosions of energy.
Many of these phenomena can be seen from our planet. They do not need large scientific teams or much knowledge to enjoy the beauty of the dark sky. The Universe generates many wonders to observe, and they cannot be missed with the naked eye, although some could pose a real danger to Earth, such as the meteorites mentioned later. If you're interested in learning more about these types of events, you can consult outstanding astronomical phenomena.
The good thing about all this is that our planet It has a large protective layer that has limited the entry of many space bodies. The truth is that most of them do not affect the planet, but in a very beautiful way can be seen in the silence of the night. For this reason, we present to you some of the most persistent mysteries of the Universe that remain unsolved, but you should appreciate at some time.
Four phenomena are mentioned here. you can delight from planet earth. It is always good to take a few minutes to breathe and be able to observe the splendor, breathing under the open and totally clear sky. In fact, it could be said that five phenomena are mentioned that you can enjoy: they are meteors, comets, meteorites and artificial satellites. However, the meteor shower, a sub-classification of meteors, is also described.
One: The Meteors
Dust particles in space are meteors. These particles are as small as a grain of sand or rice. As they cross Earth's orbit, they are intercepted and impact our atmosphere, burning up completely as they pass through it. This process takes only a few seconds, but they are usually bright enough to produce an impressive flash that is visible from Earth.
Meteors give rise to beautiful visions in space, crossing the night sky and are some of the most popular observation points in the sky. In some cases, they are long trails. On a typical clear night, around 5 meteors can be seen per hour. These dust particles mostly come from the remains of comets, which, as they pass close to the Sun, release a large amount of material in the form of meteoroids (dust particles). If you want more information about the Shooting Stars, this link will be useful to you.
When mentioning this characteristic phenomenon, you will surely think that it is a totally different body from shooting stars. However, meteors, in addition to bearing this name, are also often mistakenly called Shooting Stars due to the short time in which they can be observed in the dark sky. A subclassification of meteors, are precisely the meteor showers, which are described below.
meteor showers
The subclassification of meteors, is la meteor shower. It is a phenomenon in which, during certain days of the year, the number of meteors visible in one night increases considerably. They occur because the Earth in its orbit crosses an area with abundant dust particles, which have been scattered in the form of a trail by a comet. When the planet Earth crosses that zone, it is possible to see between 20, 50, even more than a hundred meteors per hour (in meteor storms even thousands per hour can be seen).
The meteors appear to come from a particular region of the sky. This region is the area where the particles are scattered. This area is called radiant and to help orient oneself in its location, the showers are called according to the constellation where the radiant is located. An example of this is in the constellation of Leo, the Leonidas rain is not located; in the case of Perseus, there is the Perseid shower; among other cases.
The calibration that is done to the activity of the rain, is done through a standard measurement that goes by the name of Zenital Hourly Rate (THZ). This hourly rate is nothing more than the number of meteors that can be visible through an observer, in one hour, with ideal conditions and the radiant at the zenith.
Two: Comets
These are widely known celestial bodies, due to their particular configuration. A comet It is a bright body with a "tail" or "hair" that can be as long as 1 AU (distance from the Earth to the Sun). Comets are of great importance because they are composed of a wide range of rocky and organic material: some are even essential for the emergence of life. If you are interested in the different types of stars, might be of interest to you.
The elements of comets are arranged as an icy "crust" on their surface, which does not have a visible tail until it gets close enough to the Sun. It is at this time that radiation and the solar wind cause the comet to shed many tons of material in the form of dust and gas, forming the “tail”. It always points away from the Sun, because the tail is simply the material ejected or "pushed" by the solar wind.
every few years comets return and again become visible from planet Earth. This happens because comets usually have very long and elliptical orbits. Seeing them pass close to Earth is very beautiful and their records are historical. However, if any of these passes through the atmosphere, it could be fatal for some parts of the planet and the terrestrial life against which this space body impacts, which from afar turns out to be a wonder.
Three: Meteorites
Meteorites are those small objects that, unlike a meteor, do not completely disintegrate when passing through the earth's atmosphere. This causes the meteorites to reach the surface, consequently forming a crater. These are less than 50m in size. however, it can be said that "large" meteorites are much rarer than small ones, which are only a few centimeters.
According to spatial records, meteorites are much less frequent than meteors. This is due to the action of the atmosphere that destroys most meteoroid particles in a few seconds. Fireballs also fall into this category, described as "balls of fire" with a large trail, which are seen for several seconds or minutes. They are really dangerous to be close to any of these bodies, since the impact against the Earth is at risk.
The racing cars are usually accompanied by a crash or explosion. This is what destroys part of the meteor, while some fragments reach the surface and become meteorites, although without leaving a marked crater. Craters left by meteorites can destroy any living thing that hits them. Human beings, obviously, animals and plants, since the explosion that accompanies them on their journey turns out to be fatal.
Four: Artificial satellites
Only planet Earth has artificial satellites, since they are the objects that are put into orbit around the Earth by the same human beings. Satellites themselves (communications, military, scientific, climatic, among others) fall into this category. However, other objects are also included, such as the International Space Station, the space shuttle or the Hubble Space Telescope.
They are phenomena seen from Earth, because on a dark and clear night. Although it is not a natural phenomenon, rather it is created by man, an artificial satellite can be seen with the naked eye as a faint point that draws attention from Earth, since it moves faster than the apparent motion of the stars. Even an artificial satellite can cover the entire celestial vault in just 5 minutes.
These scientific devices are easily distinguishable from stars due to their speed and other characteristics, such as light reflection. Natural satellites are stationary, whereas the light from an artificial satellite flickers. Objects like the Spacial station or the space shuttle, are much easier to observe than the others that are in space, as long as they pass through the coordinates where the person who wants to observe it is located.
Iridiumflare
A type of communications satellite (66 in total) from the Motorola company put into orbit to provide mobile satellite communications, is called Iridiumflare. The main purpose of these satellites went bankrupt and they now have military applications. However, they have a separate mention here because, due to the configuration of their antennas, the Iridium satellites reflect the Sun's light in a very powerful way.
These reflections produce flashes that on Earth can reach between magnitude -4 to -7. Which is a magnitude that makes it highly bright. An example of magnitude is that of the planet Venus, which has magnitude -4. The brief but strong flashes are called Iridium flares, or Iridium flashes. In addition to being curious to observe them (for which you can find out if any will transit our area), these satellites are often confused with UFOs.
These are the seven spatial phenomena that are not seen with the naked eye
In addition to the phenomena that can be observed, the Universe has a infinity of celestial bodies They have their own mysteries. It is not necessary to travel so far from planet Earth to know that there is a phenomenon that deserves the curiosity of the human being. The same neighboring planets, which are within the Solar System, have their own distinguishing characteristics and many of them have their own mystery.
The Universe is so immense that the human being has not been able to cover it completely, an immense list would be made of everything that would be found within it and that is a mystery for those of us who live on planet Earth. However, between what is attainable in sight and between what can be mentioned, the list is still long enough to be able to describe the greatness of space in the astronomical aspect.
Not every single discovery can be mentioned. In fact, second after second, astronomers spend their time studying each space phenomenon and every moment they observe new movements and behaviors in the cosmos. Many of the observations end in conclusions that are not true, but are simply inquiries according to what is known. Some of them, of course, are quite interesting and should not be left unmentioned.
Meteorological phenomena These are other mysteries of the universe that scientists study intensely. For this reason, we will describe here as much as possible the most notable phenomena that have been observed in the Universe, through the different studies of the astronomers and scientists. Below are seven of the phenomena that, although they cannot be seen with the naked eye, are known to be there due to scientific contributions. These phenomena are not all there is, but they are a good representation of them.
One: The color of Jupiter's Great Red Spot
This phenomenon can only be seen through large telescopic equipment or, rather, those that have been launched into space. It is very likely that you have seen the photos of this gigantic red storm located in the Jupiter's southern hemisphere. It has been active for at least 400 years. What is known is that it is a phenomenon similar to a hurricane, that it could swallow three Earths by its size and that it is colder and higher than the surrounding clouds.
After years of observation, astronomers have also discovered that it changes color. East phenomenon generates the mystery to know the cause of why the colors alternate between a pale pink and a bright red. And that is shrinking. For this reason the question arises as to why it lasts so long? And why does it change color? So far no one knows.
Just the fact of imagining being an astronaut limits me to get closer to investigate what this great red spotWe don't know how future scientists will do it, but they'll surely do their best to discover the condition of this spot. Today, exposing any research equipment to that area of Jupiter would carry a high risk of losing it. If it's already possible for a hurricane to swallow three planet Earths, obviously, telescopic equipment would be a small appetizer.
Two: Saturn's icy rings
The planet Saturn has ultra-thin ice cream rings. These are another familiar part of our Solar System, yet they are just as mysterious as Jupiter's Great Red Spot. Although it is closer than an extrasolar planet, not much is known about Saturn. What is known so far about these rings is that they are made up of some components that can cause some of the forces to cause the rings to change shape.
The NASA scientistsThey also claim to know for sure that they were formed 4.400 billion years ago. But on the other hand, scholars still don't know how Saturn's rings formed. They also haven't been able to figure out why they're made almost entirely of ice, and they also don't know why they're able to maintain a nearly perfect flat shape. Form that looks like a skating rink and that in fact at the cinematographic level analogies have been made with respect to these rings and skating rinks.
While the reasons why this planet has these ice rings are discovered, scientists do multiple investigations and inquiries about it. There may not be an answer so far, but while cinema and creativity lovers know, they can take advantage of artistic talent and let their imagination run wild, by being inspired by the different space bodies and their phenomena, such as these beautiful rings. saturn ice cream
Three: Hot Jupiters
No, it does not mean that Jupiter has multiplied or that it has come close to the Sun. These phenomena are exoplanets They have a mass similar to that of the planet Jupiter. We know that Jupiter is one of the furthest planets from the Sun. However, what is impressive is that they orbit much closer around their parent star than other known planets, hence the difference with our solar planet.
The jupiters They are one of the first types of exoplanets that astronomers began to discover in large numbers in our galaxy. The puzzling thing about them is how close they are to their stars. Possibly, planets so close could mean that they were once farther away and gravity gradually attracted them. There are many inquiries. But the specific answers are unknown.
The closeness with its star and the similarity with Jupiter, is what makes them call them Hot Jupiters. Until now, it is completely unknown how this can happen. Moreover, it has been proven that their orbits are oriented in random way about the spin axes of their parent stars. In fact, many hot Jupiters orbit in the opposite direction from their suns, which is really strange.
Four: Cataclysmic Variable Stars
In our galaxy, different types of stars have been seen. However, some are really mysterious, since their behaviors are unknown. For this reason, the intrigue arises to learn more about these space bodies. Especially when stars develop in pairs. Such is the case of a type of binary star that is called cataclysmic variable.
Cataclysmic variable stars are dwarf stars that orbit very close to their companion stars. They are so close that they take away some of the other star's own gas. The origin of this class is still unknown. stars of the Universe. Until now it is estimated that its origin could be, thanks to the remains of an event in which one of the two stars became a red giant and ate its companion.
It is also said that once inside the red giant star, the former was able to exhaust all the gas from the larger one, leaving behind a premature dwarf star. Now the former red giant is so small that it orbits around the one that was once inside it. It seems totally impossible, but the truth is that there are many known behaviors in space and this is one of the theories. Of course, without showing yet.
Five: Gamma Ray Bursts
Another of the spatial phenomena are these and it is usually said that the gamma ray bursts, are the brightest electromagnetic events in the Universe. They are called flares because they release more energy in a few seconds than a normal star produces in its entire lifetime. However, this event only lasts a few minutes, allowing it to be enjoyed from a distance. Perhaps it wouldn't be possible to enjoy it from afar due to all the energy they release.
UC Berkeley astrophysicist Martin Sirk says that this phenomenon has actually been known for 40 years. However, their cause is still unexplained and totally unknown. Investigations and inquiries into them continue. Questions also arise such as: Are these exploding black holes? The answer is still unknown, but it is a possibility. One of many.
Six: The Shape of Dark Matter
One of the greatest mysteries in universal space is the shape of the dark matterHypothetically, it can be argued that this matter does not emit enough electromagnetic radiation to be detected. However, it is also claimed that they arise due to a gravitational effect on visible matter.
Most likely, dark matter exists basically because the behavior of visible matter in the galaxies, it wouldn't make sense if there weren't other forces pushing and moving things. In addition to creating gravitational fields.
Regarding this mystery, the hubble telescope was able to portray information that even states that dark matter could have a lattice structure and that galaxies could tend to crowd around its nodes. However, we still do not have the slightest idea of what it is or what it is composed of or if it is a completely different substance from the known ones.
Seven: The structure of the Universe itself
One of the greatest phenomena that exists. How to verify the size of the total Universe, if it has not even been possible to discover what its true form is? To think that while we are sitting here, far away from us, the Universe has a behavior in which dark energy causes a constant acceleration of size. Only the size of the Observable Universe can be said, which is only what is visible from planet Earth.
Definitely nothing beats the mystery of how the Universe formed. It is unknown what its shape is or why it is expanding at such a rapid rate. Dark energy is one of the forces speculated to be causing the expansion of the universe. But what is that energy exactly? Perhaps it is a force like gravity, a force that affects all matter. We do not know.
Whatever it is, many experiments confirm that the Universe is constantly expanding, and ever more rapidly. This brings us back to another mystery: when did this expansion begin? planck space telescope has been a great contributor to astronomers. This telescope detected the light of the first moments of the Universe.
The light detected by Planck made researchers create different layers of that light, which have revealed something truly incomprehensible: all the points at the beginning of the Universe seemed to have more or less the same temperatureThe mystery is perhaps one of the greatest, as it is how and why the Universe has expanded so much while remaining relatively uniform. Perhaps one day the answers to these phenomena will be discovered.
