The moon'melts down' and scientists are stunned

According to a newly published study month Experts are puzzled by this discovery.

Research published in Scientific advancement, May be the result of water found in the molten moon, but it’s still shocking given the lack of oxygen and water in the Earth’s celestial satellite.

“It’s very confusing,” said Shuai Li of the University of Hawaii, the study’s lead author. statement. “The moon is a terrible environment for hematite formation.”

The massive lava tubes on Mars and the Moon can be homes of life. Researchers

Li was investigating data from the JPL Moon Mineralogy Mapper, and realized that the researchers sensed “spectra (or reflected light from the surface)” and discovered that the lunar pole had a very different composition than the rest.

The abstract of the study showed that the polar surface showed a spectrum consistent with the mineral hematite (Fe2O3).

“It has been speculated that the oxidation process works on the lunar surface and forms iron-containing minerals that contain iron, but it has yet to be revealed to unambiguously detect iron minerals that form under highly reduced conditions on the moon,” the researchers said. Wrote in the abstract of this study. “Analysis of the lunar mineralogy mapper data shows that the iron mineral, hematite, exists at the lunar high latitudes and is mostly associated with the eastern and equatorial planes of the tops of the terrain, and occurs more on the near side than on the far side.”

“At first I didn’t fully believe it, it shouldn’t exist depending on the conditions that exist on the moon,” added research co-author Abigail Fraeman, NASA JPL planetary earth scientist. But since we discovered water on the moon, people have been speculating that if that water reacted with rocks, there could be more different minerals than we think.”

Scientists are bewildered where rust occurs due to the lack of an atmosphere that supplies oxygen to the moon and the solar wind from the sun carrying hydrogen, which should act as a “reductant” to prevent oxidation. However, they believe it could originate from Earth because the Moon has “traces of oxygen” thanks to the Earth’s magnetic field.

The discovered hematite was not so far near the rime found on the moon, adding another complexity to the discovery. Scientists have suggested that dust particles hitting the moon can unlock water molecules and interact with hematite, but further research is needed to see if this is correct.

“The influence of tiny water and dust particles can cause the iron in this body to rust,” explains Fraeman.

“This discovery will change our knowledge of the lunar polar regions. statement. “Earth may have played an important role in the evolution of the lunar surface.”

The moon is much younger than it was initially believed, according to a new study

The moon has been a source of fascination for mankind for many years. Apollo In the mid-20th century, space exploration significantly increased human knowledge of celestial satellites.

Scientists recently Lose water A study published in March 2019 found that when meteors hit the surface.

NASA’s ARTEMIS mission also revealed that solar winds have a significant impact on the lunar surface, scarring the lunar surface and exposing it to the sun’s radiation. Similar to “sunburn”. It is due to the weak magnetic field of the moon.

Separate study published in August 2019 suggestion The moon is 100 million years older than previously believed, and was based on analysis of the lunar rocks taken by Apollo astronauts.

Research published in January 2019 suggestion A lump of 4.1 billion-year-old Earth was discovered month By Apollo Astronaut.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
