Mountain-size ‘planet killer’ asteroid will make a close approach to Earth today — and you can watch it live – Livescience.com

A massive “planet killer” asteroid will make a very close approach to Earth today (June 27), safely zipping past our planet at around 58,000 mph (93,000 km/h). The “potentially hazardous,” mountain-size object is one of the largest space rocks to pass close to Earth in more than a century — and you can watch the close encounter live.

The asteroid, 2011 UL21, is a near-Earth asteroid, meaning its orbit occasionally puts it within 1.3 astronomical units (AU) of the sun — or roughly 1.3 times the average distance between Earth and the sun.

It orbits our home star once every three years. Based on past observations, the space rock is somewhere between 1.1 and 2.4 miles (1.7 to 3.9 kilometers) wide, according to SpaceReference.org, meaning it’s larger than 99% of known near-Earth asteroids, according to the European Space Agency (ESA).

2011 UL21 is likely at least 10 times smaller than the largest space rock to ever hit Earth, the Vredefort asteroid, and around five times smaller than the rock that wiped out the dinosaurs around 66 million years ago.

However, while any potential impact from 2011 UL21 would be less extreme than these historic collisions, the asteroid still has the potential to cause damage on a continental scale and eject enough debris into the atmosphere to trigger significant climatic changes, which is why it is considered a “planet killer.”

Asteroid 2011 UL21 will zoom past at around 4.1 million miles (6.6 million km) from Earth, which is closer than it’s been to our planet for at least 110 years, according to simulations by NASA’s Jet Propulsion Laboratory (JPL). At this distance, it is considered a potentially hazardous object by NASA. However, this is still around 17 times farther away from our planet than the moon.

Although the space rock poses no threat to Earth — either now or in the future — it is interesting because it’s probably one of the 10 biggest asteroids to pass within 4.7 million miles (7.5 million km) of our planet since 1900, Gianluca Masi, an astrophysicist and director of the Virtual Telescope Project (VTP), wrote in a recent statement.

You can watch 2011 UL21’s closest approach thanks to a free livestream from the VTP, which will share the view of the asteroid from the Bellatrix Astronomical Observatory in Ceccano, Italy. The stream begins at 4 p.m. ET on June 27, with the close approach predicted to occur 15 minutes later.

You may also be able to spot the asteroid in the night sky with a decent telescope. It will be at its brightest on June 28 and June 29 and should be visible from the Northern Hemisphere if you know where to look. At its brightest, it will have a similar brightness to Proxima Centauri — the nearest known star to the sun, according to VTP.

2011 UL21 will not get this close to Earth again until 2089, when the space rock will get to within 1.7 million miles (2.7 million km) of our planet — more than two and a half times closer to us than its current approach, according to JPL simulations.

There is zero chance that any known planet killer asteroid will slam into Earth for at least the next 1,000 years. However, there will be some close calls with smaller asteroids in the next few years. For example, the asteroid Apophis, which is big enough to wipe out an entire city, will zip past Earth closer than some satellites in 2029.

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.
