CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting.

Telescopes on Earth and in space — including Hubble — have teamed up to study the unique explosion of high-energy radiation first observed in July. Astronomers reported Tuesday it’s unlike anything they’ve witnessed before.

The repeated bursts of gamma rays were detected over the course of a day, according to scientists. That’s highly unusual since these kinds of bursts normally last just minutes or even milliseconds — rarely no more than a few hours — as dying stars collapse or are torn apart by black holes.

Scientists said such a long and recurrent gamma ray explosion is puzzling — a cosmic whodunit, at least for now. More observations are needed to confirm its precise whereabouts.

The European-led team announced its findings in the Astrophysical Journal Letters in August.

A Winnipeg man convicted of killing two First Nations women more than a decade ago — with charges stayed in a third slaying — has been sent back to prison less than a year after he left under conditions.

Parole Board of Canada officials revoked 67-year-old Shawn Lamb’s statutory release after a hearing last week.

“Your actions are not beyond your control, yet you continue to wilfully make poor decisions that place the public at risk,” board member Arun Kundu-Thomsen wrote in a decision released this week.

Lamb gained statutory release — a legislated conditional release most federal inmates automatically qualify for after serving two-thirds of their sentence — in November last year and lived in several Ontario facilities for federal offenders.

Transit, roads and city council’s priorities

Erna Buffie 5 minute read 2:00 AM CDT

Did any of you happen to notice that the week of Sept. 14 marked an interesting confluence of events in Winnipeg? First up was the mayoral debate on public transit. Second was an announcement that the city would be undertaking a survey to determine whether their citizens’ “transportation needs” are being met.

The debate on our public bus system, from which our current Mayor Scott Gillingham was tellingly absent, focused primarily on safety rather than the efficiency of the system.

Which, on one level, is no great surprise.

After all unlawful incidents on buses and at transit stops have increased by 280 per cent compared to levels recorded around 2016. Moreover, the candidates were primarily speaking to the bus drivers’ union that organized the event, and bus drivers are often the victims of violent episodes.

Jets new backup Stevenson ‘stoked’ to be in tandem with Skinner

It didn’t take long to get the dirt on the newest member of the Winnipeg Jets.

Meet Clay Stevenson, who has no problem if you prefer to refer to him by his long-standing nickname of “Mud.”

“You know, Clay is in the mud, and there you go. That’s it, right there,” Stevenson said Wednesday with a laugh. “I got it in juniors when I was playing in Coquitlam, and kind of stuck ever since.”

Stevenson is now hoping to make a name for himself in a city that, quite fittingly, translates to “muddy water” in Cree. The 27-year-old from Alberta was placed on waivers by the Washington Capitals and claimed by the Jets, who were looking to clarify a goaltending situation which was as murky as the Red River.

Jets bench boss Arniel talks rebuilding from last season’s struggles

Mike McIntyre and Ken Wiebe 12 minute read Yesterday at 5:42 PM CDT

Scott Arniel has a lot on his plate these days.

But the head coach of the Winnipeg Jets took some time Thursday to sit down with Free Press hockey writers Mike McIntyre and Ken Wiebe to discuss a number of topics on the eve of a new hockey season. This interview has been condensed and edited for clarity.

Wiebe: What was the evaluation of last season like? What did you personally do in an attempt to improve after going from first-overall to 26th-overall?

I just went back and looked at things and made sure my communication was where it needed to be with my players. Was my communication where it needed to be with my boss, with my general manager (Kevin Cheveldayoff)? How our coaching staff worked. How we handled highs and lows. Things I felt I could have done better.
