The world of astronomy is excited. Scientists have discovered “galactic bubbles,” large cosmic structures thought to be fossils left over from the “Big Bang.” An international team of astronomers reports a new discovery. That might revolutionize our entire understanding of cosmology. That’s the discovery. The first “Bubble of Galaxies” is an unimaginably gigantic cosmic structure with a diameter of over one billion light years. and is believed to be the fossil remains left following the “Big Bang” or the huge explosion that caused the universe to be born. Scientists develop new energy source To be able to live on the moon Chandrayaan-3, the lunar probe that makes India’s dreams come true What is the “South Pole of the Moon”? Why must powerful nations send spacecraft to explore? The team of scientists who discovered it stated that This space bubble is 10,000 times wider than the Milky Way galaxy in which we live. Callan Howlett from the Faculty of Mathematics and Physics University of Queensland One of the team members who found it said: “This amazing bubble is a fossil from the Big Bang, 13 billion years ago. When the universe was born…we weren’t even looking for it. But this structure is so large that it overwhelms the edge of the sky we are analyzing,” he said, adding, “It dwarfs many of the largest structures we know, such as the Sloan Great Wall. And the Boots cluster of galaxies is actually just one part of this bubble… What’s even more unbelievable is that It’s right behind our house.” This galactic bubble is centered regarding 820 million light-years from our galaxy, which is very close to our Milky Way galaxy. Howlett said. This discovery provides a clearer picture of the universe’s expansion rate. And this discovery might revolutionize cosmology. “Our analysis suggests that This is because the bubble is larger than expected. The universe is therefore likely to expand beyond what was initially predicted… We are now one step closer to a major change in the field of cosmology. The entire model of the universe may need to be re-evaluated,” Howlett said. The discovery also confirms a phenomenon first proposed in the 1970s by Canadian-American cosmologist Jim Peebles. and winner of the Nobel Prize in Physics which theorizes that In the ancient universe which at that time had the appearance of hot plasma The turbulence of gravity and radiation produce so-called sound waves. “Baryon acoustic oscillation” (BAO), when sound waves ripple through plasma. They create bubbles. Until regarding 380,000 years following the Big Bang This process stops when the universe cools. The bubbles formed by BAO then grew larger as the universe expanded. Similar to other fossils formed following the Big Bang, astronomers previously detected signs of BAO in 2005 when looking at data from nearby galaxies. Researchers stated that The newly discovered bubble is a single acoustic baryon oscillation. This was the first time Brent Tully, an astronomer from the University of Hawaii, was found.

Comet Nishimura: A Rare Celestial Discovery and its Historic Passage
2023-09-08 13:10:25
This comet was named Nishimura, following the Japanese amateur astronomer Hideo Nishimura, who first observed it on August 11, 2023. Nicolas Biver, a researcher at the National Center for Scientific Research at the Paris Observatory (PSL), pointed out the rarity of discovering comets like this. Clarity in a very short period of time, as most comets are discovered months or even years before they approach the Sun. The comet has a long orbit, as its last passage near the Sun was not in 437 years, and no historical records have been found of its previous visit in Astronomical records. Experts say that when comets approach the sun, the ice in them begins to melt and releases a tail of dust that reflects sunlight, and this tail is what we will see from Earth. Comet Nishimura will pass its closest point to the sun on September 17, when it will be 33 million kilometers from the sun and 125 million kilometers from Earth. The color of the comet’s tail will be green due to the presence of more gases than dust in it. The most famous comets The history of comets has long been considered to be full of wonderful events and unique astronomical scenes. Scientists and astronomy enthusiasts enjoy following these phenomena with a passion to understand the secrets of the universe and learn more regarding the formation of the solar system and its history. The world has witnessed many comets, the most famous of which in history was Halley’s Comet. This comet is distinguished by the fact that it passes near the Earth approximately every 76 years. The last time it passed near Earth was in 1986, and it will return in 2061. Comet Nison was also one of the brightest comets of the twentieth century. It witnessed its transit of the Sun in 1973. The world also knew regarding Comet Hale-Bopp, which was clearly visible in 1997 and became a subject of public viewing. It was distinguished by its long and clear tail. Comet “ISON” in 2013 showed a very bright and bright tail in the sky in 2013. As for Comet Newchilk, it was clearly visible in 1996 and was amazing because of its huge tail.

NASA thinks it has found the crater formed by the impact of the Russian probe Luna-25
2023-09-01 16:32:00
The photograph was taken by the LRO (Lunar Reconnaissance Orbiter) probe, in orbit around the natural Earth satellite since 2009.
Teams from the US space agency compared images taken before and following the moment of impact, and observed “a new small crater”, explains a press release.
This one “is regarding 10 meters in diameter”, NASA said, and is “regarding 400 km from the planned landing site for Luna-25”.
The American space agency said it had sent commands to the LRO probe to go and observe the area communicated by the Russian space agency Roscosmos as the estimated place of the crash.
Since the crater is “close to the estimated impact point of Luna-25”, NASA teams “conclude that it is likely the result of this mission, and not a natural projectile”.
Nearly fifty years following Moscow’s last successful lunar mission, the nearly 800-kilogram Luna-25 probe crashed into the lunar surface on August 19 following an incident during a pre-landing maneuver .
Only days later, India became the first nation to land a spacecraft near the south pole of the Moon, an unexplored area that is now the focus of all attention, as there is water in the form of ice.
Nasa released an image Thursday evening of a new crater on the Moon, most likely formed by the impact of the Russian Luna-25 probe, which crashed into the lunar surface regarding two weeks ago.
