A research team led by Sebastian Zieba, a graduate student at the Max Planck Institute for Astronomy (MPIA), has discovered an exoplanet, TRAPPIST-1 c, regarding 40 light years away in the constellation Aquarius. ) has revealed that it does not have a thick atmosphere like that of Venus. According to the research team, when thermal radiation (wavelength 15 μm) from the dayside surface of TRAPPIST-1 c was observed with the James Webb Space Telescope’s Mid-Infrared Observatory (MIRI), the dayside temperature was approximately It turned out to be 110°C (approximately 380 Kelvin). This is up to 390°C lower than that of Venus, meaning that there is no thick atmosphere that produces a strong greenhouse effect, mainly composed of carbon dioxide. 【▲ An artist’s impression of the exoplanet TRAPPIST-1 c (left) reflecting the results of this research (Credit: Illustration: NASA, ESA, CSA, Joseph Olmsted (STScI); Science: Sebastian Zieba (MPI-A) , Laura Kreidberg (MPI-A))]TRAPPIST-1 c is one of the seven exoplanets found in the red dwarf “TRAPPIST-1″, and orbits outside the habitable zone of TRAPPIST-1. doing. With a diameter of 1.10 times and a mass of 1.31 times that of Earth, it is believed to be a rocky planet similar in size to Earth and Venus. The distance to its main star, TRAPPIST-1, is only regarding 1.6% of the distance from the Earth to the Sun. It is believed that In this case, one side of TRAPPIST-1 c is always daytime and the other side is always nighttime. Red dwarfs are smaller than the Sun and have a lower surface temperature, but it has been pointed out that they may strip away the planet’s atmosphere because they emit strong stellar winds and ultraviolet rays. Zieba commented on the motivation for the research, “I wanted to know whether TRAPPIST-1 c might escape the fate of atmospheric dissipation and retain a solid atmosphere, and whether it might resemble Venus.” doing. Regarding TRAPPIST-1 b, which revolves further inside TRAPPIST-1 c, research results have already been announced that it has become clear from observations with the Webb Space Telescope that it is a Mercury-like planet without an atmosphere. It has been. RELATED: Webb Space Telescope measures temperature of exoplanet TRAPPIST-1b No atmosphere possible It is said that the possibility of existence in 1 c still remains. Whether or not TRAPPIST-1 c has an atmosphere will be revealed by additional observations by the Webb Space Telescope or by observations by the European Southern Observatory (ESO)’s Very Large Telescope (ELT), which is scheduled to start observations by around 2030.

A meeting of the National Security Council is planned for the coming days. The SPÖ had previously requested this.
The Nehammer office also said that the chancellor was receiving hourly situation updates from all available channels. This is how you get a constantly updated picture of the situation.
Nehammer and his EU counterparts had already expressed concern on the fringes of the “European Forum” in Göttweig: “Nuclear weapons must not get into the wrong hands,” said the Chancellor. He is in contact with EU colleagues, and the Western secret services are constantly analyzing the situation in Russia.

Power struggle in Russia: Nehammer concerned regarding nuclear weapons
GODWEIG. The events in Russia also occupied the participants of the “Europe Forum” in Göttweig on Saturday.
Power struggle in Russia: Nehammer concerned regarding nuclear weapons
“Very chaotic situation in Russia”
Italy’s Prime Minister Giorgia Meloni, also in Göttweig, said “that we in the EU must not allow ourselves to be distracted from supporting Ukraine.” It is a “very chaotic situation in Russia” that leads to instability and “clearly contradicts Moscow’s propaganda of the last few months.” You can already see “that the propaganda regarding the compactness and cohesion of the Russian regime is wrong,” emphasized Meloni. Immediately following returning to Rome later on Saturday, she scheduled a government meeting with the Italian secret services.
Nehammer emphasized the joint approach with Italy and other EU partners. “What is happening in the Russian Federation is always of the utmost strategic importance because Russia possesses biological, chemical and nuclear weapons.”
At the Europe Forum in Göttweig, Bulgaria’s President Rumen Radev also pointed out the need to quickly take measures to protect the EU member states because of the events in Russia. “If the security situation in Russia continues to deteriorate, what will happen to thousands of nuclear warheads and chemical weapons in Russia?” Radev expressed concern.
In his closing speech, which was briefly interrupted by a statement from a climate activist, Nehammer criticized Russia’s war once morest Ukraine. “A superpower with nuclear weapons has trampled on international law.”
The EU sanctions once morest Russia were necessary. “In Austria, not a single company or bank questioned our sanctions,” said Nehammer. Although Austria has been a neutral country since 1955, it “shows full solidarity with the world community” and also shows solidarity in the EU. It is also important “to name perpetrators and victims”. It is also necessary to counter “Russia’s war narratives”. “Lies are lies,” said Nehammer.

Then Gerardo Zuin (mayor of Justiniano Posse) and Josefina Sandoz, manager of the Córdoba Stock Exchange, the entity directed by Manuel Tagle, would be listed.
In the space of Horacio Rodríguez Larreta and Gerardo Morales, the negotiations continue. Within the framework of the name dance, Pedro Dellarossa sounds like the possible first candidate for national deputy, but there is no confirmation.
It is negotiated that several mayors of the Rodrigo de Loredo sector join this list. Elisa Carrió asked for an expectable place for Laura Sesma, but she is resisted by the other partners. The Civic Coalition puts at stake a seat in Deputies for the Córdoba district, which is occupied by Leonar Martínez Villada.
In this scheme, media entrepreneur Agustín de la Reta is taken as a pre-candidate for regional Parlasur.

Mario Negri unsuccessfully promoted a list of unity in the section of deputies, with a “Y” ballot scheme. Faced with the confrontation, he decided to get off. The novelty is that the current head of the UCR block in Deputies would not be on any list, so he would cease to be a member of the Lower House in December.
He was the head of the Cambiemos interblock during the Mauricio Macri government.
