A Rare Interstellar Guest

-

Comet 3I/ATLAS is lighting up the skies as it approaches its closest encounter with the Sun and Earth, offering astronomers a rare chance to study an interstellar visitor in detail.

A Rare Interstellar Guest

Comet 3I/ATLAS is only the third interstellar object ever detected in our solar system, following the famous ʻOumuamua (1I/2017 U1) and comet 2I/Borisov. Unlike comets born within our solar system, 3I/ATLAS originated far beyond, likely ejected from a distant star system long before our Sun formed.

Discovered in July 2025, the comet is estimated to be about 11 kilometers (7 miles) wide and is racing through space at more than 130,000 mph (210,000 km/h). Its unusually straight trajectory and chemical composition confirmed its interstellar origin.

NASA & ESA Capture Stunning Activity

Recent observations from NASA and the European Space Agency (ESA) show that 3I/ATLAS is becoming increasingly active as it nears perihelion (closest approach to the Sun) on October 29, 2025.

  • Gemini South Telescope in Chile captured the comet streaking across the solar system in late August.
  • The James Webb Space Telescope (JWST) revealed a large plume of carbon dioxide (CO₂) venting from its icy surface, a sign of intense sublimation as sunlight heats the comet.
  • The Hubble Space Telescope also caught images of the comet “photobombing” other observations, highlighting its growing brightness.

Astronomers expect its appearance to change dramatically after its solar encounter, possibly shedding material or altering its coma and tail structure.

Why 3I/ATLAS Matters

Studying 3I/ATLAS is scientifically invaluable:

  • Chemical Clues: Its composition may reveal how comets form in other star systems.
  • Evolutionary Insights: Comparing it with solar system comets helps scientists understand differences in planetary system formation.
  • Public Fascination: Interstellar visitors always spark speculation, with some even jokingly suggesting alien spacecraft origins.

Looking Ahead

As 3I/ATLAS continues its journey, astronomers worldwide are watching closely. Its close approach to Earth will not pose any danger, but it provides a unique opportunity to observe an object that has traveled across interstellar space.

This comet reminds us that our solar system is not isolated—it is part of a larger galactic neighborhood where cosmic wanderers occasionally pass through, carrying secrets from distant stars.

The Mysterious Black Fungus of Chernobyl: Nature’s Radiation-Eater

-
In the ruins of Chernobyl, where radiation levels remain dangerously high decades after the 1986 nuclear disaster, scientists have discovered something extraordinary: a black fungus that appears to “eat” radiation . This organism, first noticed in 1991 growing on the walls of the damaged reactor, has fascinated researchers ever since. Its ability to thrive in such a hostile environment challenges our understanding of life and survival. Radiation as Food? The fungus, known as Cladosporium sphaerospermum and related species, contains melanin , the same pigment that colors human skin. But in this case, melanin does more than provide protection—it seems to allow the fungus to absorb radiation and convert it into chemical energy , much like plants use chlorophyll to harness sunlight. This process, sometimes called radiosynthesis , suggests that radiation can be a usable energy source for certain life forms. Scientific Breakthroughs Experiments have shown that these fungi grow faster wh...

Belgium’s “Little Einstein” Achieves PhD in Quantum Physics at Just 15

-
A remarkable milestone has been reached in Belgium: Laurent Simons , a prodigy often referred to as “Belgium’s little Einstein,” has officially earned his PhD in quantum physics at the age of 15. A Record-Breaking Achievement Laurent defended his thesis this week at the University of Antwerp, making him one of the youngest people ever to complete a doctorate in physics. He began primary school at age four , finished by six , and by 12 had already completed a master’s degree in quantum physics. His research explored bosons and black holes , showcasing his advanced grasp of complex theoretical concepts. Extraordinary Talent Laurent reportedly has a photographic memory and an IQ of 145 , placing him in the top 0.1% of the population. Despite his scientific focus, he has expressed a broader ambition: after losing his grandparents at age 11, he set his sights on studying medical science to pursue breakthroughs in extending human life. Historical Context While Laurent’s ac...

41-летняя женщина потратила 120 000 долларов на открытие ресторана замороженных продуктов, а теперь он приносит 4,5 миллиона долларов в год

-
 Генеральный директор Dumpling Daughter Надя Лю Спеллман выросла не в обычном семейном ресторане. Ее родители управляли Sally Ling’s, популярным китайским рестораном изысканной кухни в Бостоне. На протяжении десятилетий она наблюдала, как ее мать и отец служили и принимали таких знаменитостей, как Джулия Чайлд и Йо-Йо Ма. Такое воспитание научило Лю Спеллман ценить настоящую китайскую кухню и вдохновило ее открыть свой первый магазин Dumpling Daughter в 2014 году. Основываясь на рецептах своей семьи, она теперь продает пельмени, которые производятся на фабрике и замораживаются свежими, в своих ресторанах и магазинах. продуктовые магазины. Согласно документам, рассмотренным CNBC Make It, эти замороженные кусочки, а также дополнительные продукты, проданные на Amazon, принесли более 4,5 миллионов долларов с ноября 2022 года по октябрь 2023 года. Лю Спеллман говорит, что три ее ресторана, все в районе Бостона, приносят большую часть этого дохода и продают до 4000 пельменей в день. «Dum...
