NASA’s Artemis I goes back to the moon without astronauts, for now

If NASA’s “uncrewed” lunar mission is successful, future Artemis missions plan to land the first woman and first person of color on the moon.

NASA

  • It took 12.9 billion years for light from the star, Earendel, to reach Earth.
  • The most distant star was found thanks to a rare alignment in cluster galaxies.
  • The star is over 50 times bigger and millions of times brighter than the sun.

Astronomers using NASA’s Hubble Space Telescope say they have found the most distant star ever recorded, a giant celestial body that was around when the universe was in the early stages of its existence. 

Light from the star, named Earendel, which means “morning star” in Old English, took 12.9 billion years to reach Earth. In 2013, NASA estimated the universe was an estimated 13.8 billion years old, meaning Earendel was born about 900 million years after the big bang. The stars findings were published Wednesday in the journal Nature.

“We almost didn’t believe it at first,” Brian Welch, astronomer at Johns Hopkins University and lead author of the study, said in a statement. “Earendel existed so long ago that it may not have had all the same raw materials as the stars around us today.”

The previous record for the most distant star ever recorded was the blue star Icarus, which was discovered in 2018. Its light takes about 4 billion years to reach Earth.

Though 12.9 billion years is an almost incomprehensible age, Earendel isn’t the oldest star ever spotted. In 2013, Hubble discovered Methuselah, which confused astronomers because it’s estimated to be older than the universe at 14.5 billion years old. 

The universe was vastly different from 12.9 billion years ago to now. 

“When the light that we see from Earendel was emitted, the universe was less than a billion years old; only 6% of its current age. At that time it was 4 billion light-years away from the proto-Milky Way, but during the almost 13 billion years it took the light to reach us, the universe has expanded so that it is now a staggering 28 billion light-years away,” Victoria Strait, postdoctoral researcher at the Cosmic Dawn Center in Copenhagen and co-author of the study, said in a statement.

New advancements: How the Webb Telescope will build on Hubble’s observations of the universe

What lies beyond our solar system?: Over 5,000 planets including ‘super-Earths,’ NASA says

Bigger, brighter than our sun 

Researchers noted in the study that Earendel is “consistent with a star of mass greater than 50 times the mass of the sun” and is millions of times brighter than our solar system’s center.

But it wouldn’t have been found had the stars not aligned, literally.

Between Earth and Earendel exists a cluster of galaxies named WHL0137-08. That seems as though it would prevent the Hubble from seeing the star, but Albert Einstein’s theory of relativity suggests objects’ mass will warp space and act as a sort of magnifying glass for celestial bodies beyond it. 

Astronomers said the cluster was in a “rare alignment” that allowed Earendel to appear brighter than it would have at other times, magnified a thousandfold. It was discovered at the edge of a ripple in space that resulted in the alignment.

Now that astronomers are aware of the star’s existence, they hope to learn what type of star it is and more of its properties using the James Webb Space Telescope that launched on Christmas Day. The $10 billion telescope is 1 million miles from Earth.

The telescope’s high sensitivity to infrared light could help astronomers understand more about Earendel and offer a glimpse of what the universe was like as it began to expand. 

“As we peer into the cosmos, we also look back in time, so these extreme high-resolution observations allow us to understand the building blocks of some of the very first galaxies,” Strait said. 

Welch hopes the telescope will detect stars that could be even more distant than Earendel.

“We may see stars even farther than Earendel, which would be incredibly exciting,” he said. “We’ll go as far back as we can. I would love to see Webb break Earendel’s distance record.”

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.
