Astronomers Have Discovered 139 New Trans-Neptune Objects

Astronomers have discovered 139 new Trans-Neptune objects, with astronomers releasing a list of 316 Trans-Neptune objects. Astronomers have released a list of 316 minor Trans-Neptune object planets (TNOs) reaching the far reaches of the solar system since the first four years of the Dark Energy Survey (DES).

The new list includes 245 DES searches, 139 not previously published. The artist’s impression of a trans-Neptunian object. Image from NASA / ESA. The goal of DES, which completed six years of data collection in January 2020, is to understand the nature of dark energy by collecting high-precision images of the southern sky.

Although the survey was not specifically designed with TNO in mind, its breadth and depth of coverage made it particularly adept at finding new objects beyond Neptune. Professor Gary Bernstein of the University of Pennsylvania said:

The number of TNOs you can find depends on how much sky you see and what a ridiculous thing you can find. Because DES was designed to study galaxies and supernovae, astronomers had to develop a new way to track motion.

Dedicated TNO surveys measure with the frequency of every hour or two, making it easier for researchers to track their movements. “Dedicated TNO surveys have a way of moving objects, and are easy to trace,” said University of Pennsylvania graduate student Pedro Bernardinelli.

Some of the key things we talked about in this document were a way to correct those movements. The team analyzed data from the first four years of DES and found 316 TNOs. Including 245 searches conducted by the survey and 139 new items that had not been previously published.

With only 3,000 currently known items, this DES catalog represents 10% of all known TNOs. The most famous TNO, Pluto, is 40 times farther from the Sun than Earth and TNO has found the distance from the Sun to 30 to 90 times Earth using the Dess data range. Some of these objects are in long-distance orbits that will take them far beyond Pluto.

The new list will be a useful scientific tool for research on the solar system. Because DES collects a wide spectrum of data on every known object and astronomers can try to find out where TNO originated, because objects that are most closely related to the Sun are different from what they are?

 Different colors are expected. have originated in more distant and colder places. Places and by studying the orbits of these objects. They may be one step closer to finding Planet Nine, a hypothetical Neptune-sized planet that existed beyond Pluto.

There are many ideas about giant planets that used to be in the solar system and no longer exist, or that have planets that are large and far away but still visible to us,” said Professor Bernstein.

Creating a catalog is the fun part of searching. So when you create this resource; You can compare what you found according to someone’s theory, which you should get. The team’s article was published in the Astrophysical Journal supplement series. More than 100 new planets were found in our solar system.

 The researchers used data from the Dark Energy Survey (DES), an international collaborative effort to map millions of galaxies, detect thousands of supernovae and detect patterns of cosmic structure that characterize the mysterious nature of dark energy. It will expose the universe that is accelerating expansion.

Astronomers have discovered more than 100 new transneptunian objects (TNOs), found on powerful planets in the solar system. For the study published in The Astrophysical Journal Supplement Series. The researchers used data from the Dark Energy Survey (DES). Which seeks international collaboration to map hundreds of millions of galaxies, detecting thousands of supernovae.

And discover patterns of cosmic structure that will reveal the nature of the mysterious dark energy that drives the expansion of our universeThe study also describes a new approach to finding similar types of objects and may aid future discoveries of imaginary planets Nine and other invisible planets.

Professor Gary Bernstein of the University of Pennsylvania in the United States said: “The amount of TNO you can see depends on how much sky you see and what weaker you can find and using the first four years of DES data, Pedro Bernardinelli of the University of Pennsylvania started with a data set of seven billion “dots” that were above the background level of the image of all possible objects discovered by the software.

He then extracted many objects that were present for several nights, including stars, galaxies, and supernovae, looking for nearby pairs or triplets before beginning a great game of “connect the dots” with a “transient” list of 22 million objects to make. To help locate objects to discover where the object will appear on subsequent nights.

The list of some 400 candidates with seven billion points was broken down, which was viewed at least six nights of observation and then the researchers had to verify their results“We have this list of candidates, and then we have to make sure that our candidates are really real,” said Bernardinelli.

To filter the list of their candidates for the actual TNO. The researchers went back to the original dataset to see if they could find more images of the object in question. Bernardinelli developed a way to stack multiple images to create a sharp scene, helping to confirm if a detected object was a real Trans-Neptune object.

They also verified that their method was able to detect known Trans-Neptune objects in the sky regions studied and that they were able to detect spurious objects that were injected into the analysis. After several months of method development and analysis, the researchers found 316 TNOs, including 245 discoveries made by Dess and 139 new articles that had not been previously published.

Astronomers found more than 100 asteroids on the edge of our solar system, the element to map dark energy south of the sky has brilliantly exceeded its parameters. The sky in the southern element has brilliantly exceeded its parameters to map dark energy. It turns out that the Dark Energy Survey has always been good at identifying small objects before Neptune.

In the first four years of data, astronomers have successfully identified 316 asteroids, of which 139 are new. Scientists say the findings are based on a deep new analysis of the previous data and the use of new techniques may help find more asteroids in distant parts of the solar system. They can also help find the mysterious planet Nine, believed to be lurking in the dark.

 The Dark Energy investigation itself has officially ended. It continued to collect near-infrared and near-infrared data on the southern sky for five and a half years, between August 2013 and January 2019. He is studying a series of objects and events, such as supernovae and galaxy clusters, believed to be influenced by dark energy, in an attempt to calculate the acceleration of the expansion of the universe.

But it turns out that the depth, width, and accuracy of the survey are useful for other things: detecting distant asteroids, a class of objects from asteroids to dwarfs with few planets or comets. We know that these celestial bodies are beyond Neptune’s orbit, which is about 4.5 billion km from the Sun, and is 30 times the distance from Earth to the Sun (hence 30 AU, or astronomical unit).

But these trans-Neptune objects (TNO) are hard to find. They are small and distant, and the area in which they roam is very dark, so there is not much reflected light there. READ Apple’s shock Coronavirus reveals it is still used on iPhone. Here, it is very convenient to see the big sky in detail.

“The amount of TNO you can find depends on how much sky you see and what is weaker.” Physicist and astronomer Gary Bernstein spoke about the University of Pennsylvania. Since the movement of TNO is distinct from the movement of galaxies and supernova remnants, the team had to find a way to retrieve these movements from the “Dark Energy Survey” data.

They started with 7 billion digits above the background noise of the data, which could detect potential targets. The team suggested leaving several items in one place at night, suggesting that they not move like TNO. The next step is to identify the grouped objects and discover how they move.

All these steps produced a list of around 400 candidates, who appeared in at least six nights, which then had to be validated. First, the team developed an image overlay method, which can sharpen the image to detect if the spots are TNO or flaws.

They then used their technique to find known TNOs to determine the reliability of their method. It was very careful and hard work, and it was worth it. The research team identified 316 TNOs, of which 139 were never released, from 30 to 90 astronomical units from the Sun.

The velocity of seven new objects exceeds the TNO peak with an average orbital distance (or semi-major axis) of more than 150 astronomical units. (In terms of background, Pluto orbits an average distance of about 40 astronomical units.) If these extreme TNOs can be confirmed, they are one of the farthest solar objects we’ve seen.

Combining these 139 new items, there is a large part in the database of around 3,000 known TNOs. So this is a very effective way to identify these elusive space rocks. The researchers will re-adjust their methods at their own pace. The research team adjusted the detection parameters and applied them to all observations in the 5.5-year dark energy survey.

The modified technology can generate hundreds of TNOs. Hopefully, they can also get evidence of planet Nine, which is believed to be in orbit around 200 AU. Some of the ways TNO orbits around the Sun indicate that a massive substance has affected its orbits under the influence of gravity, but the imaginary planet has yet to be detected.

Bernstein says: There are many ideas about giant planets that existed in the solar system and that are no longer, or are planets that are far away, they are massive, but too weak for us. Creating a catalog is an interesting part of the discovery. Then when you build this resource, you can compare what you should theoretically find with someone.

Our strange solar system becomes strange with 139 newly discovered small planets. Astronomers have discovered 139 new transneptunian objects, small planets that have been orbiting Neptune’s past. The team published their findings in the Astrophysical Journal on March 10. More than 3,000 of these items have been discovered so far. Do you think you know the solar system? think again.

A group of astronomers has located 139 new transneptunian objects, celestial bodies that orbit around the little sun, outside of Neptune in the Kuiper Belt. The most famous of these transneptunian objects is the ancient planet Pluto, but Eris, Humia, and make are also considered transneptunian objects.

There are many ideas about giant planets that used to be in the solar system and that no longer exist, or that have planets that are large and far away but still worth noting, said University astronomer Gary Bernstein Pennsylvania said in a release.

Creating a catalog is the fun part of discovery. So when you create this resource; You can compare what you have found according to a person’s theory. Researchers led by University of Pennsylvania graduate student Pedro Bernardinelli analyzed four years of data collected by the Dark Year Survey.

And also an invaluable resource for minor planets to explore our solar system. The computer software scanned more than 7 billion light sticks in images taken over several nights to find celestial bodies. Stable objects like stars or supernovae have been removed.

This limited the area to 22 million articles. Finally, the team reduced 400 possible Trans-Neptune objects, which were observed for at least six different nights. For the most promising candidates, the team returns to the original dataset to identify at least 25 different nights of the detected items.

Finally, the team observed 300 Trans-Neptune objects, of which 139 were entirely new discoveries. The findings, published March 10 in The Astrophysical Journal, may also lead scientists to the mysterious planet Nine.

A large fictional planet that some astronomers believe the sun was spinning from the far reaches of the solar system. A handful of astronomers believe that planet Nine may actually be a black hole.

So far, astronomers have discovered more than 3,000 of these transneptunian objects, which are suspected to be there. When Vera c. If the Rubin Observatory goes online for years to come, astronomers hope to find even more, expanding our understanding of what’s happening at the edge of our solar system.

Astronomers find 139 new small planets in the outer solar system. A new method of hunting minor planets exposed more than a hundred small and distant countries. And novel techniques can help solve the mystery of Planet Nine.

FarFlungPlanet: The discovery of 139 new miniature planets in the outer solar system, and especially the new method used to find them, may eventually help astronomers determine if planet nine exists.

Astronomers have discovered 139 new small planets that orbit the Sun beyond Neptune by searching for data from the Dark Energy Survey. The new method of detecting the small world is expected to reveal many thousands of distant objects in the coming years, which means they are the tip of the first hundred icebergs.

Taken together, new distant objects, as well as incoming ones, can solve one of the most fascinating questions in modern astronomy: Is there a vast and mysterious world called planet Nine on the outskirts of our solar system?

Mysteries beyond Neptune: Neptune orbits the Sun at a distance of approximately 30 astronomical units (AU, where 1 AU is the Earth-Sun distance). The Kuiper Belt, in addition to Neptune, is a band rich in frozen and rocky object comets (including Pluto) that have a mass dozens to hundreds of times larger than the asteroid belt.

They both cross their outer edge into the Kuiper Belt and enter distant 50-orbiting bodies known as Trans-Neptue Objects (TNO). Currently, we know about 3,000 TNO in the solar system, but the total number is estimated to be close to 100,000.

As more TNOs were discovered over the years, some astronomers, including Constantine Batyagin and Mike Brown of Caltech, have observed that a small subcategory of these objects has peculiar orbits.

They seem to clump together in unexpected ways, as if an invisible object moves these so-called extreme TNOs (ETNOs) to specific classes. Batagin and Brown, among other groups, such as those led by Scott Sheppard of the Carnegie Institution for Science, these ETNOs from strange circles point to the existence of a vast and distant planet from the Nine world.

planet9cluster: Over the past decade, astronomers have discovered many distant objects, all of which have similar perihelia, meaning they reach as close to the Sun at the same location in space. An important theory that attempts to explain the grouping is that a vast and unexplored world, known as Planet Nine, is hidden in the outer solar system.

Having five to 15 times the mass of Earth and orbiting around 400 AU (or far) from the Sun, proposed planet nine will have a gravitational pull that can orbit ENTNO, causing them to cluster. They also get closer to the sun. The problem is that the evidence for Planet Nine is hitherto indirect and scant.

There may be something else that explains explicit orbits, or perhaps researchers have come across some objects that are only for similar orbits. The discovery of more TNOs, particularly beyond the Kuiper Belt, will allow astronomers to find more clues that may indicate the location of the nine proposed planetariums, or deny their existence entirely.

Seven of the 139 recently discovered minor planets found in this study are ETNO, a major addition to a list that hovered around a dozen a few months ago. New camera, new method: University of Pennsylvania astronomers found a new TNO using data from the Dark Energy Survey (DES), which was not originally designed to hunt down distant planets.

Blancotelescope: The main instrument of the Dark Energy Survey is the Dark Energy Camera at the White Telescope at the Cerro Tolo Inter-American Observatory in Chile. Designed to reveal the secrets of dark energy in the universe, the data obtained from the survey can also help solve the mystery of Planet Nine.

Ridar Hahn, Fermilab: University of Pennsylvania astronomer and co-author of the new study Gary Bernstein has been fascinated by TNO since “One Thing Before Planet Nine”, and even before the existence of the Kuiper Belt was confirmed. 1990s. Bernstein told Astronomy: Every time I have a new camera in my hands or something that is technically an advance.

DES, an international effort to understand dark energy, began observing the southern skies in 2013, using a highly sensitive camera mounted on the 4-meter Blanco telescope in the Chilean Andes. Bernstein worked with astronomer Masao Sacco and graduate student Pedro Bernardinelli at the University of Pennsylvania to adapt the DES date to identify the TNO.

Bernardinelli told Astronomy: “Most people, when they try to find TNO, they have a dedicated way of looking at the sky, where they take photos for a few hours and you can move objects very easily.” The DES data did not work that way. .

Bernardinelli had to design novel algorithms that could identify moving objects by connecting dots between DES images, helping to identify if TNOs were present. The researchers then validated their motion detection algorithm against known TNOs and also confirmed that they could filter out fake objects.

To begin with, Bernardinelli analyzes a small subset of DES data. But when you apply your algorithm to the rest, you expect to find 500 or more TNOs. Then, if the same method is applied to even more sensitive survey data on the horizon, such as the new Vera c.

Through the Rubin Observatory, the group awaits thousands of discoveries of new TNOs. And with those numbers, astronomers can finally find a definitive answer on whether a giant planet in our solar system is elusive.

“This is a great example of how a survey designed for an astronomy field, to study the history of the expanding universe, can produce great science even in a completely unrelated field,” said Alexander Mustill, Theoretical Astrophysicist Astronomer at the University from Lund in Sweden.

Planet Nine Question: Batayin, who is still searching for Planet Nine, calls this new method for TNOs to find “a brilliant idea”, saying the research discovered new objects. Which may otherwise be ignored for years.

The fictional world called Planet Nine is expected to have an orbit with a super-Earth or sub-Neptune planet potentially taking off from the Sun dozens of times compared to the dwarf planet Pluto. It has not led up to. Anything decisive about Planet Nine.

The researchers who analyzed the first results revealed whether the orbits of the seven newly discovered ETNOs support a plume pattern targeting Planet Nine, but have not done anything yet. If this were the first dataset to come out, no planet would have presented hypothesis Nine.

Because there would appear to be no clustering [in the orbits of the new, says Sako. However, he says that this planet does not dislike the existence of nine. His method can discover other ENTNOs that support the proposed Planet Nine, or even detect the object itself.

Ann-Marie Madigan, an astronomer at the University of Colorado Boulder, says: “TNO is difficult to detect, so each one we find has a much more intertwined [object] population,” he says. The more TNO we know.

The more we can tell if there is evidence of planet Nine. Or, alternatively, if Madigan’s own theory of collective gravitation of very distant objects eliminates the apparent need for planetary nines.

History of our Solar System: Regardless of whether or not Planet Nine exists, understanding the orbits and properties of TNOs will provide insight into the history of the giant planets, or perhaps the giants of the past, that were on the outskirts of the system solar during its early days. He was kicked Years. Bernstein says that “the remnants of what happened in the solar system long ago are” TNO]. “They are on hold.”

Our strange solar system becomes strange with 139 newly discovered minor planets. They just came out of Neptune’s past. Outer space, planets, universe, celestial object, atmosphere, astronomy, space, galaxy, darkness, celestial phenomena.
