Toronto's mayor has expressed confidence that the shows will be safe, and that comprehensive security measures will be in place. "In addition to preparing for fun, spend a little time considering concert safety tips which stress situational awareness," writes Rozdilsky. " If something does not seem right to you, it probably is not right." Rozdilsky is also quoted in an article about published in The Week.

If you see something, say something. If something does not seem right to you, it probably is not right.

Ontario grocery stores are saying the new bottle return requirements may make it impossible to participate in Premier Doug Ford's expansion of alcohol sales. Sebastian Prins, the director of government relations for the Ontario section of the Retail Council of Canada, says the majority of the larger stores are planning to add alcohol sales at locations within five kilometres of a Beer Store, meaning they aren't obligated to accept empties right away. The Canadian Press reports that Prins is working with a to assess the costs and logistics.

However, Pilon says that councillors voting on whether to increase their own pay . Professor Joe Mihevc, who served on council for nearly three decades until 2018, tells Toronto Star that councillors are "absolutely" underpaid, estimating that between city hall meetings on weekdays, and community events on evenings and weekends, most regularly work 12-hour days. In a separate op-ed on the subject, Mihevc writes about why politicians deserve a pay raise.

Astronomers find rare galaxy from 11 billion years ago

TORONTO, May 25, 2020 鈥� Researchers have found a rare and massive collisional ring galaxy from some 10.8 billion years ago that is forming stars 50 times faster than the Milky Way, says 91亚色 Postdoctoral Fellow Leo Alcorn of the Faculty of Science.

These kinds of ring galaxies are formed when one galaxy collides with another galaxy that passes through its centre.

鈥淭he aftermath of the collision leaves behind a ring of diffuse light around the galaxy, a density wave of stellar material,鈥� says Alcorn, a co-author on the paper, 鈥淎 giant galaxy in the young Universe with a massive ring,鈥� published today in .

She adds that 鈥渢his collisional ring galaxy is believed to be the most distant collisional ring confirmed to date.鈥�

The discovery could shake up theories about the earliest formation of galactic structures and how they evolve.

Little is known about distant collisional rings, but with this finding the research team, led by researcher of Australia鈥檚 ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions, can provide what it believes is the first detailed study of a ring galaxy from 10.8 billion years ago.

鈥淚t is a very curious object that we鈥檝e never seen before,鈥� says Yuan, who is based at the Centre for Astrophysics and Supercomputing at Swinburne University of Technology. 鈥淢ost of that activity is taking place on its ring 鈥� so it truly is a ring of fire.鈥�

The researchers found the massive collision ring galaxy, named R5519, while searching for spiral galaxies.

鈥淭hese systems are rare in the local Universe but finding one at a lookback time of 10.8 billion years ago, is unexpected,鈥� says Alcorn. 鈥淲e were not expecting to see a system like this so long ago given the rarity of these events in the local Universe.

She says the importance of this finding is it will allow researchers to study significantly more about merger-driven star formation and how disk galaxies evolve and interact with their environment, as well as with neighbouring galaxies.

This galaxy is similar in stellar mass to the Milky Way, but more than one and a half times larger in stellar half-light radius. It also has a clear ring structure and large diffuse disk, resembling a giant donut. It may be the most distant collisional ring confirmed to date. The closest thing to it in the local Universe is the well-known Cartwheel Galaxy, also a collisional ring galaxy.

The hole at its centre is three million times bigger than the diameter of the supermassive black hole in the galaxy Messier 87, which in 2019 became the first ever to be directly imaged.

The team worked with colleagues from Australia, the United States, Canada, Belgium and Denmark. Spectroscopic data was gathered by the WM Keck Observatory in Hawaii and images recorded by NASA鈥檚 Hubble Space Telescope to identify the unusual structure of the galaxy.

TORONTO, July 9, 2019 鈥� 91亚色鈥檚 team is marking that historic day 50 years ago when the first human walked on the Moon as part of the Apollo 11 mission.

To celebrate the successful spaceflight that landed astronauts Neil Armstrong and Buzz Aldrin on the Moon to take their first lunar steps on July 20, 1969, the Observatory team is inviting the public to attend a free three-day event next week on Tuesday, July 16, Wednesday, July 17 and Thursday, July 18.

The event will include viewing of the Moon and other celestial objects using multiple telescopes, a screening of the film Apollo 11, and hourly presentations on lunar exploration. The Observatory team, based in the Faculty of Science, is hosting the nightly event from 8 p.m. to midnight.

The event鈥檚 lead organizer is Professor Paul Delaney, the Observatory鈥檚 director and an expert in astronomy and space exploration.

鈥淭he Moon landing was one of the pinnacles of the 20th century from a scientific and a human endeavors perspective,鈥� said Delaney, a professor in the Faculty of Science鈥檚 Department of Physics & Astronomy. 鈥淚t was something that really brought people together, and now 50 years later we have a new generation of people saying it鈥檚 time to go back to the Moon and beyond.鈥�

WHO: Professor is available for media interviews this week, next week, and while he is attending the three-day event, to discuss the significance of the Moon landing, the need for more space exploration and space tourism.

WHAT: Nightly indoor screening of Apollo 11 at 8 p.m., followed by hourly presentations on lunar exploration starting at 9:30 p.m. An Observatory team member will deliver the presentations, explaining the challenges and successes of the missions leading up to Apollo 11 and afterward. The outdoor public viewing will occur from 9 p.m. to midnight with team members on hand to explain what people are seeing. Check the Observatory鈥檚 Twitter account for a weather posting to see if the telescopes will be set up.

WHEN: From 8 p.m. to midnight each night on Tuesday, July 16, Wednesday July 17 and Thursday, July 18.

WHERE: The film screening will take place in Room 317 of the Petrie Science & Engineering Building, Keele Campus (see or #17 on this ). Observing and the lunar exploration presentations will be on the top of the Arboretum Lane Parking Garage (see聽聽or #80 on this聽).
