Most Distant 'Star' Might Actually Be a Star Cluster
The astronomical object Earendel, which is regarded as the most distant star ever observed, may not be a single star at all.
A new study led by researchers at the University of California suggests that Earendel's light is more consistent with a dense cluster of stars rather than an individual one.
According to lead author Massimo Pascale, the spectroscopic data match what astronomers expect from star clusters formed around 30 to 150 million years after the Big Bang.
Earendel was first detected more than three years ago by the Hubble Space Telescope.
What makes the observation extraordinary is that we are seeing the object less than a billion years after the universe's birth.
This glimpse into the early cosmos was only possible because a massive cluster of galaxies in the foreground acted as a gravitational lens, bending and magnifying Earendel's light on its way to Earth.
Initially, astronomers believed Earendel to be a massive B-type star—roughly twice as hot as our Sun and over a million times brighter.
This assumption inspired Pascale and his colleagues to test whether the object could instead be an entire collection of stars.
While the new analysis strengthens the case for Earendel being a star cluster, the scientific debate remains unresolved.
One of the astronomers involved in its original discovery noted that Pascale's team did not fully explore all possible explanations for the data. Both sides agree, however, that only further observations—particularly with the James Webb Space Telescope—can provide a definitive answer.
The findings have been published in The Astrophysical Journal Letters.

NASA, Google Create AI Doctor for Space
Israa Farhan NASA and Google are jointly testing a new artificial intelligence-powered medical assistant designed to support astronauts during long-duration missions to the Moon and Mars. According to the project aims to help astronauts diagnose and treat medical issues in deep space, where immediate consultations with Earth-based doctors are impossible and returning home is not an option. As part of its Artemis program, NASA is working with Google to trial a prototype called the Crew Medical Officer Digital Assistant (CMODI). The AI-driven system is designed to analyze symptoms, previous diagnoses, and test results before suggesting possible treatments or diagnostic options. The technology would give astronauts the ability to independently manage health challenges beyond low-Earth orbit, ensuring they can address medical concerns during lunar or Martian expeditions without relying on delayed communications with doctors on Earth. highlighted that this digital health assistant could also prove invaluable on Earth, especially in remote or hard-to-reach regions where medical professionals are scarce. read more UAE's Lunar Mission Delayed to Tomorrow Twitter Lifts Trump's Account Ban Scientists Find Evidence Of 10،000 Black Holes Surrounding The Center Of The Milky Way Galaxy Greenhouse In Antarctica Able To Grow Vegetables Without Soil Or Sunlight Moving Over China: U.S. Is Again Home to World's Speediest Supercomputer Technology The 10 most expensive cars in the world Technology Top 10 fastest cars in the world Technology Lasers Could Make Computers 1 Million Times Faster Technology Smart technology taking control of our lives Videos & Features Story behind Trending Jessica Radcliffe Death Video News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters Arts & Culture "Jurassic World Rebirth" Gets Streaming Date News China Launches Largest Ever Aircraft Carrier News Ayat Khaddoura's Final Video Captures Bombardment of Beit Lahia Business Egyptian Pound Undervalued by 30%, Says Goldman Sachs Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Arts & Culture South Korean Actress Kang Seo-ha Dies at 31 after Cancer Battle Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt News The Jessica Radcliffe Orca Attack? 100% Fake and AI-Generated

China Unveils Robot with Artificial Womb
Israa Farhan China has revealed the world's first robot equipped with an artificial womb, designed to carry out the full process of pregnancy and childbirth. The breakthrough, announced by Chinese company 'Kaiwa Technology', has sparked widespread debate among scientists, ethicists, and the public. The innovation was presented at the 2025 World Robot Conference in Beijing. Company founder Zhang Qifeng explained that the robot can replicate the entire journey from fertilization to delivery, maintaining a fetus for up to ten months in an artificial amniotic fluid environment and supplying it with nutrients through a tube mimicking the umbilical cord. The prototype is expected to reach the market by 2026, with an estimated price of under 100,000 yuan (around 13,900 US dollars). It is aimed at people who wish to avoid the physical strain of pregnancy as well as couples facing infertility challenges. The announcement has divided opinion. Some hailed it as a breakthrough for reproductive medicine, while others voiced serious concerns over its ethical and legal implications. Zhang confirmed that discussions are ongoing with authorities in Guangdong province to establish a suitable legislative and regulatory framework. Artificial womb technology is not entirely new. In 2017, researchers at the Children's Hospital of Philadelphia successfully sustained a premature lamb in a so-called 'biobag' until it fully developed. However, experts argue that moving from partial support for fetuses to enabling complete pregnancy remains a major scientific challenge. 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 Videos & Features Story behind Trending Jessica Radcliffe Death Video News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters Arts & Culture "Jurassic World Rebirth" Gets Streaming Date News China Launches Largest Ever Aircraft Carrier News Ayat Khaddoura's Final Video Captures Bombardment of Beit Lahia Business Egyptian Pound Undervalued by 30%, Says Goldman Sachs Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Arts & Culture South Korean Actress Kang Seo-ha Dies at 31 after Cancer Battle Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt News The Jessica Radcliffe Orca Attack? 100% Fake and AI-Generated
