Space Controversy: It's Helio-Crescent Not Heliosphere; Astronomers Reveal Earth Lives in Huge Croissant – Tech Times

Published

A new space study was revealed by researchers at Boston University on Mar 16 that might change how space should be studied. According to them, most science experts calling the protective bubble surrounding the Sun ‘heliosphere’ are all wrong. This bubble is not sphere-shaped at all but shaped more like baked good croissant or crescent– which must be called Helio-crescent.

Space Controversy: It’s Helio-Crescent Not Heliosphere; Experts Reveal Earth Lives in Huge Croissant Bubble

According to the research study made by Merav Opher, professor of astronomy and researcher at Boston University’s Center for Space Physics, and her coauthor James Drake of the University of Maryland, there seemed to be wrong information that has been accepted by millions of researchers and people from years ago. This is when the first researchers identified the bubble-like surrounding the Sun and called it ‘heliosphere.’ 

As explained by them, the shape of this bubble is not a sphere at all. Using their created image of the heliosphere, it was more like a croissant or a beach ball-shaped bubble.

For people out there still out of the blue on what is heliosphere, this is the vast space region that casts a magnetic “force field” around all the planets, deflecting charged particles that would otherwise muscle into the solar system and even tear through DNA. It was first thought to be sphere-shaped since the last five spacecraft returned with this data, including Pioneer 10Pioneer 11, Voyager 1, and Voyager 2, and New Horizons launched in 2006.

According to Opher years ago, the bubble-like force field is shaped like a comet, with a round “nose” on one side and a long tail extending in the opposite direction. In 2015, the study was even made clearer when they used a new computer model and data from the Voyager 1 spacecraft. Using the info they acquired, they suggested using the “croissant” model and explained that this image shows how the two jets extend downstream from the nose rather than a single fade-away tail. “That started the conversation about the global structure of the heliosphere,” says Opher. 

“If we want to understand our environment, we’d better understand all the way through this heliosphere,” says Loeb, Opher’s collaborator from Harvard. 

Experts: We can’t accept Helio-crescent image and change space studies quickly

Though the findings of Opher and Drake seemed to be a great research study, some experts in the field said that they could not quickly accept these claims. Especially with how huge this information can affect all space travels and studies made and published years ago.

In fact, two years ago, another study somehow supports Opher and Drake’s claims by saying that the bubble is not a sphere but neither a comet nor a croissant, but more like a beach ball. This is according to the readings from the Cassini spacecraft, which orbited Saturn from 2004 until 2017, that also debunked the original theory.

However, Tom Krimigis, who led experiments on both Cassini and Voyager, said that these theories could not be quickly accepted by the space studies. 

“You don’t accept that kind of change easily,” said him. “The whole scientific community that works in this area had assumed for over 55 years that the heliosphere had a comet tail.”

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.
