China deepens international collaboration to push forward deep-space exploration

Ammon27-04-2025

Ammon News - China, with an open stance, is collaborating with the international community to drive breakthroughs in deep-space exploration and foster resource sharing, striving to build a shared future in space.On the occasion of Space Day of China, which is celebrated annually on April 24, the China National Space Administration (CNSA) announced a series of international collaboration initiatives to advance deep-space exploration.Seven institutions from six countries France, Germany, Japan, Pakistan, the United Kingdom and the United States have been authorized to borrow the lunar samples collected by China's Chang'e-5 mission for scientific research.In 2020, the Chang'e-5 mission retrieved samples from the moon weighing about 1,731 grams, which were the first lunar samples in the world in over 40 years, helping advance humanity's knowledge about the moon.
Shan Zhongde, head of the CNSA, said China's lunar exploration program has always adhered to the principles of equality, mutual benefits, peaceful utilization and win-win cooperation, sharing achievements with the international community. Xinhua

Study warns of brain changes from football headers

Ammon News - A recent Australian scientific study has warned that repeated heading of the ball during football matches and training sessions could lead to significant changes in brain chemistry, heightening concerns about a potential link between this practice and increased risk of dementia in the long term. Conducted by the University of Sydney, the study is the first of its kind to use magnetic resonance imaging (MRI) to assess this risk. It found that adult male players who headed the ball 20 times over a 20-minute period showed elevated levels of two proteins associated with degenerative brain injuries. These proteins are considered early biomarkers for the potential development of dementia. The findings come amid growing international moves to restrict heading in younger age groups. The Football Association in England has banned heading in training for children under 12, while the Premier League has issued guidance limiting headers to no more than 10 per training session per week. In response, Football Australia has announced the formation of a research task force comprising medical experts to review existing recommendations on heading and explore appropriate measures to reduce its frequency and intensity, particularly among young players.

Nearby Sculptor galaxy revealed in ultra-detailed galactic image

Ammon News - The Sculptor galaxy is similar in many respects to our Milky Way. It is about the same size and mass, with a similar spiral structure. But while it is impossible to get a full view of the Milky Way from the vantage point of Earth because we are inside the galaxy, Sculptor is perfectly positioned for a good look. Astronomers have done just that, releasing an ultra-detailed image of the Sculptor galaxy on Wednesday obtained with 50 hours of observations using one of the world's biggest telescopes, the European Southern Observatory's Chile-based Very Large Telescope. The image shows Sculptor, also called NGC 253, in around 4,000 different colors, each corresponding to a specific wavelength in the optical spectrum. Because various galactic components emit light differently across the spectrum, the observations are providing information at unprecedented detail on the inner workings of an entire galaxy, from star formation to the motion of interstellar gas on large scales. Conventional images in astronomy offer only a handful of colors, providing less information. The researchers used the telescope's Multi Unit Spectroscopic Explorer, or MUSE, instrument. "NGC 253 is close enough that we can observe it in remarkable detail with MUSE, yet far enough that we can still see the entire galaxy in a single field of view," said astronomer Enrico Congiu, a fellow at the European Southern Observatory in Santiago, and lead author of research being published in the journal Astronomy & Astrophysics. "In the Milky Way, we can achieve extremely high resolution, but we lack a global view since we're inside it. For more distant galaxies, we can get a global view, but not the fine detail. That's why NGC 253 is such a perfect target: it acts as a bridge between the ultra-detailed studies of the Milky Way and the large-scale studies of more distant galaxies. It gives us a rare opportunity to connect the small-scale physics with the big-picture view," Congiu said. Sculptor is about 11 million light-years from Earth, making it one of the closest big galaxies to the Milky Way. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Like the Milky Way, it is a barred spiral galaxy, meaning it has an elongated structure extending from its nucleus, with spiral arms extending from the ends of the bar. Its diameter of about 88,000 light-years is similar to the Milky Way's, as is its total mass. One major difference is Sculptor's rate of new star formation, estimated to be two to three times greater than that of the Milky Way. Could this giant telescope help protect the Earth from asteroid threats? Nearly 30% of this star formation is happening near the galaxy's nucleus in what is called a starburst region, as revealed in colorful emissions shown in the new image. The observations have given information on a wide range of properties such as the motion, age and chemical composition of stars and the movement of interstellar gas, an important component of any galaxy. "Since the light from stars is typically bluer if the stars are young or redder if the stars are old, having thousands of colors lets us learn a lot about what stars and populations of stars exist in the galaxy," said astronomer Kathryn Kreckel of Heidelberg University in Germany, a study co-author. "Similarly for the gas, it glows in specific bright emission lines at very specific colors, and tells us about the different elements that exist in the gas, and what is causing it to glow," Kreckel said. The initial research being published from the observations involves planetary nebulae, which are luminous clouds of gas and dust expelled by certain dying stars. Despite their name, they have nothing to do with planets. These nebulae can help astronomers measure the precise distances of faraway galaxies. The researchers marveled at the scientific and aesthetic value of the new view of Sculptor. "I personally find these images amazing," Congiu said. "What amazes me the most is that every time I look at them, I notice something new - another nebula, a splash of unexpected color or some subtle structure that hints at the incredible physics behind it all."

Giant tortoise celebrates his 135th birthday

Ammon News - A giant Galapagos tortoise has turned 135 – and he's also just become a father for the first time, says Miami Zoo officials. Despite multiple breeding attempts throughout his lifetime, Goliath never successfully fathered any offspring. This all changed with a recent unexpected surprise. After 128 days of incubation, one egg out of a clutch of eight that was laid on January 27 successfully hatched on June 4. 'The hatchling appears to be healthy and has been removed from the incubator and placed in a separate enclosure where it is active and full of energy,' the zoo said. 'Goliath' hatched on the island of Santa Cruz in the Galapagos on June 15, 1890, and later moved to the Bronx Zoo in July 1929. Ultimately, he settled at the Miami Zoo in July 1981. Independent
