Sechelt Skies: Lunar encounters and Regulus, heart of the lion

Published

 on

This month’s article is mostly about our moon’s passes by various objects, with a bit of extra detail about one of them – the star Regulus. The evening series of ISS passes in January end with single views on Feb. 1 and 2, both passing low in the southwest. Morning passes begin about mid-February for all the morning people out there. Check the Heavens-Above website for information on these.

Venus has passed Earth and is moving to the far side of the solar system, appearing closer to the sun as it goes. Mercury did a brief appearance near it in January but that part of the ecliptic is almost level with our horizon so neither planet was very high in the sky before sunrise. Another conjunction of Venus, this time with Mars, occurs on the morning of Feb. 22 at about 06:45, when the two planets are less than a degree apart. This will be a tough one to see, though, since both are very low in the morning twilight and Mars is about one-hundredth as bright as Venus. It would look a lot better from Australia, of course; both planets would be directly above the sun and a lot higher in the sky. Oh well.

The last quarter moon starts off this month, passing about a degree left of Spica in Virgo as it rises after midnight on Feb. 1. By Feb. 4 and 5, it passes Antares in Scorpio and actually occults it. We won’t see it, however, because instead of 30,000 feet of cloud, we’ll have a few thousand miles of rock in the way. Most of Asia should have a better view.

Lunar perigee occurs Feb. 10, one day after the new moon so we’ll have higher than usual spring tide ranges for a few days. By Feb. 14 evening, the moon is about four degrees right of Jupiter. From my understanding of Greek mythology, if I were Selene, the moon goddess, I’d keep my distance from the king of the gods, but who am I to judge. In the evening of Feb. 16, the moon is just a few degrees left of the Pleiades cluster. By Feb. 19 and 20, it passes through Gemini just three degrees below Pollux, one half of the Twins – Castor and Pollux. Feb. 23 brings the nearly full moon just three degrees left of Regulus. Coincidentally, the official full moon at 04:30 the next morning is just about at lunar apogee – it’s farthest point from Earth. Since it’s the smallest full moon of the year, I’d like to nominate it as an UnSuper Moon, okay?

Incidentally, the star Regulus, the brightest and the “Heart” of Leo, is unusual in several ways. First, it’s almost exactly on the Ecliptic, the path in the sky traced by our sun’s apparent motion as we orbit it. That means that most solar system objects pass close to it or in front of it at some time. The first time I saw that was about 40 years ago one night driving in Saudi Arabia, when I noticed the quarter moon getting closer and closer to a bright star. I missed the actual occultation, though, because you don’t take your eyes off the road ever when driving there, but since then I’ve seen a few and the star just blinks out! And that’s how you realize you actually can see the moon moving through the field of stars.

The second weird thing about Regulus is that it’s spinning unbelievably fast. The main pair of stars is a blue sub-giant A (what we see) and a white dwarf companion B (which we don’t). The main star is about 3.8 times the sun’s mass and shouldn’t be long-lived enough to have a white dwarf companion. The current theory is that Regulus A was less massive and slow burning until the companion star aged, burned hotter, swelled into a giant and lost its outer layers to its partner, Regulus A. Conservation of angular momentum means that the orbital momentum of that falling gas was transferred to Regulus A, which added mass and spun it up to its current high speed. It is currently rotating about once every 15 hours compared to 25 days for our sun. That high rotation speed stretches it out such that its equatorial radius is about twice that of its polar radius and its atmosphere at that equator is just about up to orbital velocity. I picture it as what might happen if the guy working in the pizzeria could spin that dough really, really fast as he tossed it in the air.

In news unrelated to the upcoming high tides the SCAC monthly meeting will not be at the Sechelt Library this month because of their recent tsunami event. Please check the club website at: sunshinecoastastronomy.wordpress.com/ for news.

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.
