How an ancient collision with another galaxy transformed the Milky Way

The Hubble Space Telescope has discovered evidence that our galaxy experienced a significant collision and merger with a dwarf galaxy 11.8 billion years ago. Mergers between galaxies are one of the main ways in which galaxies can grow. However, while we can witness mergers taking place in other galaxies, figuring out our Milky Way galaxy's history requires painstaking detective work. Even now, the story is only partly known. "Our home is the Milky Way galaxy, but we do not know how our house was built," Davide Massari of the Astrophysics and Space Science Observatory of Bologna in Italy said in a statement . Massari is lead author of a paper describing the discovery of an ancient galactic merger. "In this paper we discover where the first significant batch of bricks came from: a dwarf galaxy that we call LKH." LKH stands for Low-energy–Kraken–Heracles, which is an obtus...

Scientists find dead star that predicts our sun's future: 'Broken apart and returned to the galaxy'

Image
Astronomers have watched a dead star, in the guise of the Helix Nebula, being recycled back into the interstellar gas from which it originally came, bringing the story of that star full circle. Stars can last for millions, or even billions, of years, but they do not last forever. When a sun -like star reaches the end, it blossoms into a beautiful planetary nebula . The Helix Nebula , located 650 light-years away in the constellation of Aquarius , the Water Bearer, is one such example of a planetary nebula. The Helix's central star has run out of hydrogen needed for nuclear fusion reactions in its core. This caused the core to begin to contract and raised the temperature in the star's outer layers, which ignited fusion reactions there instead. This had the effect of causing the star to bloat into a red giant . Then, eventually, the outer layers of that red giant detached and expanded in...

A little-known protein may be fueling Alzheimer’s — and scientists found a way to block it

An experimental Alzheimer’s compound prevented damaging protein clumps from forming in the brains of mice, helping nerve cells survive longer and reducing amyloid buildup. The treatment also appeared to improve heart health and slow some signs of aging, raising hopes for an entirely new way to combat dementia. from Latest Science News -- ScienceDaily https://ift.tt/3j2Mlpg

COVID-19 awakens dormant viruses — and one is linked to long COVID

COVID-19 can reactivate dormant viruses hiding in the body, including Epstein-Barr, cytomegalovirus, and several herpes viruses. One poorly understood viral family was strongly associated with long COVID and lasting disability, offering a potentially important clue to why some patients struggle to recover. from Latest Science News -- ScienceDaily https://ift.tt/ANrO0pR

'This goes beyond showcasing technological soft power': China's new moon map signals bold space ambitions (video)

Image
Chinese researchers have presented a new map of the moon, updating a previous edition based on new scientific findings and recalibrating the moon's ancient geologic eras. The comprehensive map of the moon , with a scale of 1:5 million, was unveiled by the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS) on Aug. 6. The map is an update of a 2024 edition and puts forward new boundaries for the ancient Aitkenian, Nectarian and Imbrian lunar periods. (The researchers use the term Aitkenian, whereas the term pre-Nectarian is often used to describe the lunar geologic period from roughly around 4.5 billion to 3.9 billion years ago.) The map also uses reprocessed spectral data to update areas of KREEP terrane , which features crustal material enriched in potassium (K), rare-earth elements (REE), and phosphorus (P), and is found to be more continuous and abundant than previously e...
