Mars Rover’s Dead, Comet Incoming, JWST’s First Exoplanet

Published

 on

Keep your eyes on the sky for a comet, another Mars rover has died, the leaky Soyuz will be replaced, JWST dominates the American Astronomical Society meeting, and Starship is just around the corner.

 

A Good Comet is Coming

Keep your eyes on the sky over the next few weeks for your first chance to see a comet in 2023. Designated C3/2022 ZTF, the comet was first discovered in March 2022, and it has been getting closer to Earth and brightening. It’s expected to reach its brightest point in early February, taking a path through the sky to bring it close to the Big Dipper and Cassiopea. Astronomers have calculated that it’s on a 50,000-year orbit, so it’s been eons since its last visit. It should look great in a pair of binoculars or a small telescope.

Another One Bites The Martian Dust

The terrible dust on Mars has claimed another victim. This time it’s China’s Zhurong rover, which was supposed to wake up from hibernation on December 26th. China’s Nationational Space Administration has tried to reestablish communications with Zhurong, but they’ve been unsuccessful. The rover was put into hibernation six months ago to help it survive the Martian winter when temperatures get down to -100C. A regional dust storm also cloaked the area, reducing the energy it could use to keep its batteries operational.

The Leaky Soyuz Needs to Be Replaced

The Soyuz MS-22 that was leaking coolant last month will be replaced. This decision was made after inspecting the ship currently attached to the ISS. Roscosmos will launch the replacing MS-23 ship in February in an autonomous mode. Temperatures inside MS-22 can climb into the low 40s. Thus, it is considered unsafe to use in a crewed flight unless absolutely necessary. The other option for the ISS crew is the Crew Dragon which should be able to carry up to 7 people. But let’s hope that it won’t be needed.

James Webb Finds Its First Exoplanet

James Webb confirmed its first exoplanet. It was first discovered and marked as an exoplanet candidate by the TESS telescope. It’s called LHS 475b and it’s located 41 light-years away from us. The interesting part is that the planet has almost the exact diameter of Earth. For now, JWST definitely confirmed the existence of the exoplanet, but it also did observe its atmosphere. Researches will need some more time to determine its exact composition.

Early Galaxies from James Webb

This week the American Astronomical Society is meeting for the first time since the James Webb Space Telescope became operational, so there’s been a mountain of Webb news. One remarkable story is this image of primordial galaxies captured by JWST. These galaxies are just a few thousand light-years across and have so much star formation they’re heating the surrounding gas and dust, so it glows in the ultraviolet (redshifted to infrared after billions of years). Their structure matches newly discovered “green pea” galaxies, which have the same behavior and are much closer, and, therefore, easier to study.

Build your own ELT

Got a little extra time on your hands? Here’s to keeping you busy. The European Southern Observatory has released a paper model of its Extremely Large Telescope. Although the actual telescope will measure almost 40 meters across and can see Earthlike planets orbiting sunlike stars, yours will be much smaller, made of paper, and can’t make any observations at all. Still, it’ll be fun, and you can learn more about the telescope as you craft yours out of paper.

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.
