It’s your chance to view a comet this week

Published

 on

What better way to open the new year than by spotting a hopefully bright comet? It is referred to as comet C/2022 E3 (ZTF) and it could be putting on a decent show in northern skies throughout January.

This will be a great chance to test that new set of binoculars or telescope you may have received for Christmas.

This ice mountain was discovered in March of 2022 by the wide-survey camera operating at the Zwicky Transient Facility. At first, astronomers believed the tiny, distant object was an asteroid. However, it quickly brightened as it passed the planet Jupiter on its way to the inner solar system to round the sun.

At this distance, the sun’s influence begins to react with the comet’s frozen elements, compounds and water ice causing it to sublimate from a solid to a gas. The comet now begins to glow and in most cases forms an ion (gas) and sometimes even a dust tail. Now it was classified as a comet.

The comet appears green in colour and is the result of the breakdown of a reactive molecule called dicarbon and is sporting a faint ion tail only. C/2022 is well placed in northern skies and be seen all night long. It will be close to Polaris (the North Star) at the end of January. Unlike a meteor that streaks for a fraction of a second as it vaporizes in our atmosphere, comets are interstellar visitors that slowly move against the background stars from night to night and are located millions of kilometres away.

C/2022 E3 (ZTF) closest approach to the sun called perihelion occured January 12 at 160 million kilometres distance. Over the next few weeks, the comet will approach our planet (not directly). Its closest approach to the earth will occur on February 2 at a safe distance of 42 million kilometres.

There is a finder chart on my website: www.wondersofastronomy.com.

In general, comets are unpredictable. Even though calculations suggest it will be visible in the dark countryside on a clear moonless night, it could easily fizzle away like Comet Kohoutek back in 1973. Expectations of being the brightest comet of the 20th century and given the name “Comet of the Century”, Kohoutek was bright but much dimmer than predicted. As my long-time friend and comet hunter David Levy says, “Comets are like cats: they have tails, and do precisely what they want.”

Throughout any given year, amateur astronomers can observe a handful of comets but only through telescopes as they are too faint to be seen just by looking up. Hopefully, C/2022 E3 (ZTF) will not disappoint and allow you to see this particular visitor that is estimated to have last returned to our neck of the cosmic woods some 50,000 years ago. This was the period of the early homo sapiens. Unfortunately, the Neanderthals became extinct some 10,000 years after the last approach of this comet.

As the weeks go by, the moon will rise later and later and show less of its illuminated phase meaning less sky glow. The new moon occurs on January 21. This comet is not expected to be as great as Comet Neowise back in July 2020. However, you still have a chance to see a somewhat bright space tourist that will return 50,000 years from now.

You can also try your hand at wide-angle astrophotography with a DSLR camera, cable release and a sturdy tripod. If you do not own an automated telescope, there are good camera trackers on the market that allow you to take long one or two-minute exposures and still have pinpoint stars. The colourful comet would register on the camera’s CCD chip. Experiment with the manual exposure settings, after all, pixels are free.

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.
