London – “The Gulf”
Researchers from the Natural History Museum in Britain have found extraterrestrial water for the first time in a meteorite that fell in the United Kingdom.
The Winchcombe meteorite, which fell in Gloucestershire in February last year, is believed to hold clues regarding the source of Earth’s vast oceans.
Ashley King, a researcher in the Planetary Materials Collection at the Natural History Museum, said 12 percent of the meteorite sample consisted of water.
He added, “The composition of the water in the meteorite is very similar to the composition of the water in the Earth’s oceans, which is evidence that asteroids and meteorites such as “Winckcombe” made a very important contribution to the Earth’s oceans.”
King stressed that “Winckcombe” is the only meteorite that falls to Earth and contains water, noting that it was not contaminated with water and materials on Earth.
He added, “We are trying to match the composition of water meteorites and other materials found outside Earth with the composition of water on Earth.” While most of the meteorites that we find are contaminated.
“One of the big questions we have in planetary science is where on Earth did the water come from,” the museum researchers said. And one of the obvious places is either through comets that have loads of ice in them, or through asteroids, and there is always a debate, were asteroids the main source?”
He explained that the composition of the water in “Winckcombe” is likely the main source of the water of the inner solar system to Earth, and we have data indicating that some asteroids match well with Earth, and “Winckcombe” confirms the same story.
Speaking at De Montfort University, which hosts the festival, Dr. King said the analysis showed that the meteorite came from an asteroid somewhere near Jupiter. It formed 4.6 billion years ago, and its journey to Earth took 300,000 years.
There are approximately 65,000 meteorites known on Earth.

James Webb Telescope stuns the world with pictures of a stellar nursery in the Orion Nebula!
written by Alexandra Hartman Editor-in-Chief
pick up telescope James Webb Astronomers have released new images containing intricate details of a stellar nursery in the Orion Nebula, revealing how stars and planetary systems are formed.
The images shed light on an environment similar to our solar system when it formed more than 4.5 billion years ago. Observing the Orion Nebula will help astronomers better understand what happened during the Milky Way’s first million years of planetary evolution, said an astrophysicist at Western Else University Peters in a press release. .
“We were amazed by the new images of the Orion Nebula. We started this project in 2017, so we have been waiting more than five years for this data. These new observations allow us to better understand how massive stars transform gas and the dust cloud in which they were born.”
Stellar nurseries, like the Orion Nebula, are obscured by large amounts of stardust, making it impossible to study what’s going on inside with instruments like the Hubble Space Telescope, which relies primarily on visible light.
However, Webb detects infrared light of the universe, which allows observers to see these layers of dust, and detect motion occurring deep within the Orion Nebula, making these the most detailed and clear images ever taken of the nebula, which is located in the constellation Orion 1,350 years away. Photovoltaic from the ground.
“Observing the Orion Nebula was a challenge because it is too bright for Webb’s unprecedentedly sensitive devices,” said research scientist Olivier Bernay of the French National Center for Scientific Research at CNRS.
New images reveal many structures within the nebula, including Proplyds, a central protostar surrounded by a disk of dust and gas in which planets form.
“We’ve never been able to see the intricately fine details of how interstellar matter is formed in these environments, and how planetary systems might form in the presence of this harsh radiation,” said Emily Fabart, associate professor at the Space Astronomical Institute. Interstellar medium in planetary systems.
Also visible at the heart of the Orion Nebula is a trapezoidal group of young, massive stars that make up the dust and gas cloud with their intense ultraviolet radiation, according to the news release.

In details.. this is what space flights cause in the bodies of astronauts
written by Alexandra Hartman Editor-in-Chief
Flying in space may cause negative problems for the human body, as astronauts who spend long periods in space suffer from health concerns..
A number of experts have put forward the most worrying effects that space travel can have on the human body.
DNA mutations
A team of researchers looked at astronauts’ blood stored for 20 years to study the effects of space travel, and in a shocking study, they found that astronauts’ blood showed signs of mutation in DNA..
And space experts explained: “The researchers found a higher frequency of somatic mutations in the genes of the 14 astronauts included in the study, compared to the statistics of the population who went to space.“.
muscle atrophy
The absence of gravity weakens the muscles used by astronauts on Earth, but not in space, and this is called muscular atrophy, and these muscles are usually referred to as the anti-gravity muscles and include the calf muscles, thigh muscles, back and neck muscles.
NASA further explains: “Because astronauts work in a weightless environment, our muscles contract too little to support their bodies or move, without regular use and exercise our muscles weaken and deteriorate.”“.
NASA adds: “Studies have shown that astronauts experience up to 20 percent loss of muscle mass in spaceflights lasting five to 11 days.”“.
eye problems
Most of these concerns arise when astronauts are on the International Space Station (ISS) Or wearing space suits, due to the lack of gravity, which can lead to the accumulation of body fluids in the head.
This puts pressure on the eyeballs, causing a condition called neurogenic eye syndrome associated with spaceflight (SANS).
Other eye problems can range from flat eyeballs to enlarged optic nerves and poor eyesight, according to a 2011 study published in the Journal of the American Academy of Ophthalmology. The risk of these problems is especially high for astronauts who spend more than six months in space..
heart contraction
Time in space can cause an astronaut’s heart to shrink, according to a study published in the journals AHAAnd in 2021, it was revealed that the heart of NASA astronaut Scott Kelly shrank following spending 340 days aboard the International Space Station, and Scott’s heart returned to its normal size when he returned to Earth..
Researchers believe that space shrinks hearts because it doesn’t have to pump once morest gravity.
Anemia in space
The effects of zero gravity over time can cause the human body to destroy its own red blood cells, this phenomenon is referred to as “space anemia” and scientists do not know why it occurs.
And a new study published in the journal Nature Medicine Space causes the human body to destroy red blood cells at a faster rate than on Earth.
The researchers worked with 14 astronauts over a period of 6 months, and their results showed that the astronauts were destroying regarding three million red blood cells every second, which is 54% higher than the average rate here on Earth..
The results showed that 5 of the thirteen astronauts whose blood was drawn when they landed on Earth were suffering from anemia, and according to the study, the longer a person stays in space, the longer he suffers from anemia on Earth.

Who names the planets in outer space | nnda-nnlt | TRENDS
written by Alexandra Hartman Editor-in-Chief
The universe is infinite. there are always new discoveries of planets, asteroids and other celestial bodies which should be given a name. Some have been called (8275) Inca, Cusco, Santa María de Colón, Serpiente, TRAPPIST-1d, PSR B1620-26 b, Kepler-186f… Who is in charge of such a task?
Advances in science and technology have recently made it possible to detect more celestial objects, including exoplanets, planets that orbit other stars. The first exoplanets were discovered just three decades ago and more than 5,000 have been identified since then. Naming them, without a doubt, is a marathon task, to whom has it been entrusted?
WHO NAMES THE PLANETS AND CELESTIAL BODIES IN OUTER SPACE?
The International Astronomical Union (UAI). Since 1919 it is the institution in charge of registering all the planets, moons, asteroids, exoplanets, etc. that are discovered and, in addition, uses a rigorous system of nomenclature depending on the type of celestial body. To do this, he has resorted to all kinds of encyclopedias and religions, even his public contests are becoming popular. This 2022, has launched a contest to name 20 exoplanetary systems that the James Webb telescope (JWST) will observe.
WHAT IS THE INTERNATIONAL ASTRONOMICAL UNION?
The International Astronomical Union (IAU) is responsible for studying the objects of space and analyze their characteristics to classify them into categories. In 2016, they decided to reclassify Pluto as a dwarf planet.
Its mission is to promote and safeguard astronomy in all its aspects, including research, communication, education and development, through international cooperation. The IAU brings together more than 12,000 active professional astronomers from more than 100 countries around the world.
