Portuguese explorer wins award for artificial intelligence tool for exploring exoplanets – DNOTICIAS.PT



Portuguese explorer wins award for artificial intelligence tool for exploring exoplanets - DNOTICIAS.PT

The creation of an artificial intelligence tool that allows highly accurate data collection on exoplanets, which contributed to the implementation of the mission of the European Space Agency, won the researcher Louis Simoins in the Ariel Machine Learning Data Challenge.

The award was presented after Louis Simoins improved his ability to detect exoplanets by capturing the light emitted from a star using a highly accurate algorithm.

The task was launched by the European Space Agency (ESA) to provide the necessary conditions for the study of exoplanets (planets that orbit a star but do not belong to the solar system) in the Ariel mission, which will be launched in 2029. …

For the Portuguese researcher who “occasionally competes in machine learning for space,” the competition had the advantage of developing his “ability to solve problems and apply different algorithms” and keep abreast of developments in artificial intelligence. “.

To a problem that he considered “excellent because of its relevance and complexity,” he answered by creating a solution with an average error of 0.00007.

“The specific task – the detection of exoplanets – is solved by different approaches, but the one that turned out to be more successful is associated with the study of light curves, therefore, the light that comes to us from the star, and when the planet passes forward in its orbit, the shape that takes this curve tells us a lot about the planet, ”explained Luis Simoes to Luce.

He admits that this method has already been used to “identify thousands of exoplanets,” “but this mission has a very ambitious goal,” which includes “understanding the chemical composition of the atmospheres of these planets.”

“It will only be possible with tools that are not there today, hence the interest, 10 years ago, to start learning and challenge the community,” added Luis Simoins.

The solution he came up with does not provide any new data, but Luis Simoins created “a model, almost error-free (…) high-precision model.”

This accuracy matters, because “the question of the chemical composition of the atmosphere is the subsequent processing of the data that the algorithm will give.”

“There he already enters into other areas of astrophysics, but the fact is that if an incorrect interpretation is made at this stage of the data interpretation chain, then the next steps will be misled as to what the real characteristics of the planet will be.”, Materialized.

For this, the algorithm is programmed “automatically based on the training data”.

To this end, the team leading the ESA mission “has created synthetic data using simulators that recreate with maximum accuracy at the moment what data the mission will collect in the future.”

This data was distorted “due to data distortions that may arise during the mission – due to thermal fluctuations, due to the whole problem of measuring hundreds of light years, how many photons are coming from different sources”, but knowing what the original data was , it was possible to assess the degree of accuracy of the presented solutions.

“We are several years away, this is not the final model, but it is already a significant step towards achieving the levels of accuracy that the mission wants to have,” the researcher said.

Luis Simoins began working on the use of artificial intelligence for solving space problems, creating “systems for Airbus and ESA to control the landing of ships on other planets.”

In 2008, due to the crisis, he moved to the Netherlands, where he began to cooperate with the ESA.

He returned to Portugal in 2018, where he founded ML Analytics with his wife.

Sniper Elite 5 gets a new cinematic trailer; Find out the details!



Sniper Elite 5 recebe novo trailer cinematográfico; Confira os detalhes! 1

A Insurrection revealed today cinematic trailer your latest game, Sniper Elite 5. It’s been a while since we commented that this logo will get a trailer and the release date has been kept, the same will released later this year for different platforms, from PS4 on PC and will be released on launch day Game Pass neither PC nor Xbox.

In the trailer we see our sniper jump on rooftops Cathedral turned into hidden outpostsv Mission to infiltrate a Nazi base. Check it out below:

Something that we will have as news in Sniper Elite 5 is a new game mode known as Invasion, where a multiplayer mode with different rooms will be implemented; we have to enter campaign mode of other players and we strive for kill the same; this was briefly demonstrated in the trailer, where our character appears aiming for a certain event. This game mode was inspired by Dark souls.

OUR CTO and co-founder yes Rebellion, Chris Kingsley commented mode, check it out: The invasion mode is A fantastic addition to the Sniper Elite 5 gaming experience. A human-controlled attacker can act in such a diverse and unpredictable way that increases complexity e increase the tension even more. The player will be informed that a sniper has entered the Axis joined the game, and from that moment it becomes exclusively a game of cat and mouse. intense and high risk.

For those players who just want to get a gaming experience Single player gamethere will be an opportunity disable intrusion mode, but we encourage everyone to try it out at some point. We had a lot of fun with him in the studio, jump into each other’s games and finding innovative and stealthy ways to defeat each other.

James Webb returned home. Super telescope is ready to reveal the secrets of the universe



James Webb returned home.  Super telescope is ready to reveal the secrets of the universe

OUR James Webb Space Telescope has arrived at its destination and taken another major step in a process that prepares for an unprecedented mission: to unravel some of the universe’s deepest mysteries, such as the origin of life.

According to the plan, the telescope was located in orbit of the second Sun-Earth Lagrange point, also known as L2, about 1.5 million kilometers from Earth, where it would orbit the Sun, in line with the Earth and in the same way as it orbits around L2. L2 is located in the outer part of the Earth’s orbit, along the line connecting the Earth and the Sun.

The position reached after activating the telescope’s thrusters, which ran for almost five minutes (297 seconds to be exact) to correct James Webb’s trajectory with respect to the final orbit, is a very important aspect for the success of the mission. The chosen and already reached point was chosen because of the view of space, and also because it was a place without interference and with adequate temperature, the main ingredients for the onboard instruments to work at their best.

The telescope’s primary mirror segments have already been installed, as has the secondary mirror, but there is still a lot of work to be done before James Webb can send images. In the coming months and before the summer, it will be necessary to adjust all the instruments of the telescope. Three months are provided for optical tuning only.

One of the highlights of the steps already taken was the deployment of the 21-meter protective cover of the super telescope, consisting of five layers, an operation completed at the beginning of the month. The tennis court-sized sun visor was folded to fit in the cone-shaped cargo hold of the nose of the Ariane V missile. mechanical dance for the discovery of its five layers began on December 28 last year, three days after its launch into space.

James Webb, who is commonly referred to as the successor Hubblewill collect data that will help explore all stages of the history of the Cosmos, from the depths of our solar system to the most distant galaxies observed in the early Universe, and everything in between.

The operation, which involves a $10 billion investment, includes NASAEuropean Space Agency (THAT) and the Canadian Space Agency (CSA). The final positioning of the telescope was achieved this Monday, January 24, during a trajectory correction operation that took place at 19:00 Lisbon time. OUR mission start took place on December 25th. Check out or view the images that marked the day in the gallery below.

The new European Samsung Galaxy S22 will be equipped with an Exynos 2200 processor

As the date of the announcement of the new Samsung Galaxy S22 family of smartphones approaches, publications begin to appear on social networks, which in some way confirm many of the rumors that have appeared.

One of the most pressing doubts is related to the new SoC (System-on-Chip) from Samsung. new exynos 2200, which features the new Xclipse 920 graphics controller using the AMD RDNA2 architecture.

According to this Twitter post, which lists the SoCs that will be distributed across different regions, it was created with firmware development in mind, which is being created for the new Galaxy S22.

If proven, the European continent will be the only region where the new Exynos 2200 will be exclusive, and the markets where both SoCs are available, such as Africa, the Middle East, and Southwest Asia, the rest will be Snapdragon 8 Gen1 exclusive. . . .
