NASA Discovers Mysterious 'Super-Earth' Planet Sending Repeated Signals
NASA has announced the discovery of a mysterious planet similar to a "super-Earth," known as TOI-1846 b, which is emitting repeated signals from a distance of 154 light-years away.
The agency explained that the planet is twice the size of Earth and has four times its mass.
It orbits a small, cool red dwarf star in a tight orbit, taking only about four days to complete a revolution. This tight orbit causes a strange, repeated dimming of the star's light.
NASA noted that both space-based and ground-based telescopes have identified the planet as belonging to a rare category known as the "radius gap". This group falls between small rocky planets like Earth and larger gas-rich planets like Neptune.
Despite the planet's surface temperature being estimated at around 600°F (316°C), scientists do not rule out the presence of water.
NASA also stated that TOI-1846 b orbits much closer to its star than Mercury does to the Sun in our own solar system. The host star is about 40% the size and mass of the Sun.
NASA scientists hope to use the James Webb Space Telescope (JWST) to study the planet's atmosphere using infrared technology. The goal is to search for signs of water vapor, methane, carbon dioxide, or other gases.

Iran Unveils Breakthroughs in 3D-Printed Concrete, Smart Batteries
Israa Farhan Iranian researchers have developed advanced 3D-printed concrete with enhanced freeze resistance and innovative lithium batteries strengthened by natural compounds, marking significant progress in sustainable construction and energy storage, according to Pars Today, a partner of TV BRICS. The research, conducted at Amirkabir University of Technology, addresses key challenges in both sectors. In the construction field, scientists tackled the vulnerability of 3D-printed concrete to environmental stress, particularly freeze-thaw cycles, by introducing an air-entraining additive. This compound generates micro air bubbles within the concrete structure, dramatically improving its durability and resistance to freezing conditions. In the energy sector, the team focused on improving lithium battery performance and longevity by combating the formation of solid electrolyte interphase (SEI) layers, which typically degrade battery capacity over time. Using curcumin, the active ingredient in turmeric, they developed a natural, stable coating that protects electrodes, boosting the battery's capacity, thermal stability, and lifespan. These dual innovations demonstrate Iran's expanding presence in global scientific research. The freeze-resistant concrete has the potential to accelerate rapid, resilient infrastructure development, while the turmeric-enhanced lithium batteries offer a sustainable and longer-lasting solution for modern energy needs, including portable electronics and electric vehicles. read more Gold prices rise, 21 Karat at EGP 3685 NATO's Role in Israeli-Palestinian Conflict US Expresses 'Strong Opposition' to New Turkish Military Operation in Syria Shoukry Meets Director-General of FAO Lavrov: confrontation bet. nuclear powers must be avoided News Iran Summons French Ambassador over Foreign Minister Remarks News Aboul Gheit Condemns Israeli Escalation in West Bank News Greek PM: Athens Plays Key Role in Improving Energy Security in Region News One Person Injured in Explosion at Ukrainian Embassy in Madrid News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters News China Launches Largest Ever Aircraft Carrier Sports Former Al Zamalek Player Ibrahim Shika Passes away after Long Battle with Cancer Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt Arts & Culture South Korean Actress Kang Seo-ha Dies at 31 after Cancer Battle News "Tensions Escalate: Iran Probes Allegations of Indian Tech Collaboration with Israeli Intelligence" News Flights suspended at Port Sudan Airport after Drone Attacks Arts & Culture Hawass Foundation Launches 1st Course to Teach Ancient Egyptian Language Videos & Features Video: Trending Lifestyle TikToker Valeria Márquez Shot Dead during Live Stream

2025 Global Energy Prize Announces Laureates
Rana Atef According to TV Brics , the Global Energy Prize International Award Committee has announced the names of the 2025 laureates. Among the winners are researchers from China and Russia whose discoveries and innovations offer new solutions for the generation, transmission, and use of energy. The TV BRICS International Media Network served as an international partner of the event. The award in the Conventional Energy category was presented to Jinliang He, chair of High Voltage Engineering Research Institute, professor at China's Tsinghua University (China), for the development of advanced ultra- and extra-high voltage power transmission technologies. Russia's representative, Vladislav Khomich, head of research at the Institute for Electrophysics and Electric Power of the Russian Academy of Sciences (RAS), became the laureate in the New Ways of Energy Application category for his contribution to the development of pulsed energy and plasma technologies. This year, the prize received 90 applications from scientists across 44 countries. The shortlist included 15 nominees from 8 countries. The winners were announced at a ceremony held in Krasnoyarsk. The event was attended by Governor of the Krasnoyarsk Territory Mikhail Kotyukov; President of the Global Energy Association Sergey Brilev; Chairman of the Global Energy Prize International Committee Rae Kwon Chung, as well as jury members from China, South Africa, Russia, and other countries. 'The Krasnoyarsk Territory applied to host the awards announcement ceremony. The prize nominees presented many interesting ideas and projects; this is also a major educational effort,' said Kotyukov. The ceremony also featured a speech by Yulia Nazarkina, Head of the Africa Division at the International Cooperation Department of TV BRICS. 'The Global Energy Prize promotes scientific development and highlights the importance of international cooperation, which is why TV BRICS has long been a media partner of the award,' she emphasised. In addition, international media partners from BRICS countries took part in the event, including Piet Rampedi, Editor-in-Chief of African Times (South Africa); Pawan Kumar, Copy Editor of IANS (India); Liu Hongjie, Chief Correspondent of China Daily (China). A special highlight of the ceremony was a video greeting to the laureates from the International Space Station by cosmonauts Sergey Ryzhikov, Aleksey Zubritsky, and Kirill Peskov. The official award presentation will take place during Russian Energy Week, to be held in Moscow from 15 to 17 October. read more CBE: Deposits in Local Currency Hit EGP 5.25 Trillion Morocco Plans to Spend $1 Billion to Mitigate Drought Effect Gov't Approves Final Version of State Ownership Policy Document Egypt's Economy Expected to Grow 5% by the end of 2022/23- Minister Qatar Agrees to Supply Germany with LNG for 15 Years Business Oil Prices Descend amid Anticipation of Additional US Strategic Petroleum Reserves Business Suez Canal Records $704 Million, Historically Highest Monthly Revenue Business Egypt's Stock Exchange Earns EGP 4.9 Billion on Tuesday Business Wheat delivery season commences on April 15 News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters News China Launches Largest Ever Aircraft Carrier Sports Former Al Zamalek Player Ibrahim Shika Passes away after Long Battle with Cancer Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt News "Tensions Escalate: Iran Probes Allegations of Indian Tech Collaboration with Israeli Intelligence" Arts & Culture South Korean Actress Kang Seo-ha Dies at 31 after Cancer Battle News Flights suspended at Port Sudan Airport after Drone Attacks Arts & Culture Hawass Foundation Launches 1st Course to Teach Ancient Egyptian Language Videos & Features Video: Trending Lifestyle TikToker Valeria Márquez Shot Dead during Live Stream
