Astronomers have detected three asteroids in close proximity to Earth, two of which pose a potential threat as “planet killers” because of their larger and hazardous size, but don’t worry, says a NASA expert, they aren’t expected to hurt us.

According to findings published in the peer-reviewed Astronomical Journal on Monday, the three asteroids – which belong to a group found within the orbits of Earth and Venus – were previously undetectable via telescope due to the glare and brightness of the sun.

However, an international space team of astronomers waited until twilight at an observatory in Chile to examine the asteroids using a dark energy camera from a Víctor M. Blanco 4-meter Telescope, according to the National Science Foundation’s NOIRLab.

The biggest asteroid is the most hazardous object to prompt a significant risk to Earth in the last eight years, researchers say. One of the asteroids, named 2022 AP7, is a little less than one mile wide but has an orbit that could reach Earth’s path in the distant future. A timetable is uncertain, though, according to findings in the journal.

Skyscraper-sized asteroid to pass Earth: Here’s how close it will actually get

The other two asteroids, 2021 LJ4 and 2021 PH27, pose less of a risk to colliding with Earth, researchers say.

“Our twilight survey is scouring the area within the orbits of Earth and Venus for asteroids,” lead study author Scott S. Sheppard, an astronomer at the Earth & Planets Laboratory of the Carnegie Institution for Science in Washington, D.C., said in a statement. “So far we have found two large near-Earth asteroids that are about 1 kilometer across, a size that we call planet killers.”

Scientists from the study determined the asteroid with most likelihood to cross Earth’s orbit will currently “stay well away from Earth,” largely because the sun would block it since its timing of crossing Earth’s orbit would be when Earth is on the opposite side of the sun.

Should an asteroid that’s half a mile long ever connect with Earth, the results to the planet could be “devastating,” according to Sheppard, because of the impact pollutants would have on the atmosphere.

“It would be a mass extinction event like hasn’t been seen on Earth in millions of years,” Sheppard said.

Threat of asteroid hitting Earth ‘is not hazardous’: NASA expert

While the observed asteroids could have devastating impacts on the plant, don’t assume it’ll actually collide with Earth, said Paul Chodas, director of NASA’s Jet Propulsion Laboratory Center for Near Earth Object Studies who was not involved in the study.

“We know this asteroid is not hazardous,” Chodas told USA TODAY. “It remains very far from Earth, kind of locked in a residence that keeps it as being actually one of the most distant of the asteroids that we categorize as potentially hazardous.”

The center tracks all space objects that cross or approach Earth’s orbit around the sun. There are over 30,000 near-Earth asteroids that have been discovered, but 857 of them are just over half a mile wide, per NASA. According to the center’s database, the asteroid 2022 AP7 is only projected to have close approaches to Mars and Jupiter in the next 145 years.

Chodas said the asteroid’s ability to cause destruction took away from the main point of the survey because it’s an excellent example of searching for asteroids that are too close to the sun for us to see, which should continue to be done.

2021 PH27 is the closest known asteroid to the sun, the NOIRLab release said.

He added NASA plans in 2026to send a surveyor into space to observe asteroids in the region, in hopes of detecting any that could be a threat to Earth. By finding those asteroids, the agency could prepare plans similar to the DART mission, where a spacecraft crashed into an asteroid to change its path.

“The most important thing in planetary defense is to find them and to find them with lots of warning time,” Chodas said.

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

Published

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.
