What’s a supernova, you might ask?
According to NASA, it’s large explosion of a star that occurs in one of two ways.
In binary star systems, one steals matter from another, leading to an explosion when the one accumulates too much matter.
“The second type of supernova occurs at the end of a single star’s lifetime,” NASA states on its website. “As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force.”
This morning, CBC News posted a story by science journalist Nicole Mortillaro suggesting that a star in the Orion constellation—Betelgeuse—could eventually go supernova.
This star is often referred to as the shoulder of the Orion and it has dimmed considerably over the past two months. The constellation is named after the Greek huntsman god, Orion.
Supernovas don’t happen every day. According to Mortillaro, an explosion of Betelgeuse could happen anywhere from today to 100,000 years from now. And keep in mind that it’s 650 light years away from Earth.
But if a supernova happens over the Christmas holidays, it will give the world’s journalists something to talk about during one of the quietest news periods of the year.
Student at Huntsville public school tests positive for COVID-19 – Muskoka Region News
The first school-related COVID-19 case in the Trillium Lakelands District School Board has been confirmed to be a student.
During the evening of Tuesday, Sept. 22, a Huntsville parent posted a letter they received from the board confirming a positive COVID-19 case at Spruce Glen Public School in Huntsville.
“We have been notified by the Simcoe Muskoka District Health Unit (SMDHU) that a student or staff member at Spruce Glen Public School has tested positive for COVID-19. Our school is working closely with Trillium Lakelands District School Board and SMDHU and is taking necessary steps to prevent the further spread of the virus both in the school and in the community.”
Follow-up communications confirmed that the person is a female student from Huntsville between the ages of 0 and 17. A parent forwarded this newspaper the letter they received from the school on Wednesday, Sept. 23. Their child is in the same class as the siblings of the student who tested positive for COVID-19.
“The students have all taken their role to keep everyone safe, including themselves safe, very seriously. It is a real blessing! This is such a kind, caring, and amazing group of students. I am deeply moved by their considerate actions,” wrote a teacher at the school.
The school remains open at this time.
NASA tweaks space station's position to avoid collision with massive debris – National Post
NASA quickly shifted the position of the International Space Station to avoid a potentially catastrophic encounter with debris that would have passed within less than a mile of the orbital laboratory — a close shave in space terms.
The three-member crew was moved into a Soyuz spacecraft until the station was considered out of danger from the object, which was expected to pass by at about 5:21 p.m. Central time on Tuesday, the National Aeronautics and Space Administration said in a statement.
The agency didn’t reveal the size of the debris, which would have passed within 1.39 km (0.86 mile), forcing the 150-second “avoidance maneuver” burn by Mission Control in Houston. Colliding with orbital debris, or space junk, of even a few centimeters in diameter would be potentially catastrophic to the space station given that objects in low-earth orbit can travel at speeds of roughly 17,500 miles per hour (28,000 kilometers an hour) and higher.
The space station’s move occurred about an hour before the closest approach using thrust from the Russian Progress resupply craft that is docked on the ISS Zvezda service module.
Adjustments of the station’s orbit are fairly routine, although having the crew take shelter in the Soyuz spacecraft isn’t.
