Whats Happening in the World
Australian Open
Roger Federer won the Australian open for tennis after his knee injury in 2016 people were not expecting him to do as well as he did as he took some time off from training.
The Winter Olympics Pyeongchang
ACSS Pros and Cons
Pros:
I would say things like sports,activities and clubs are doing well in this school especially things like the drama and music club.I also like that we have two computer labs as some schools don't even have one.
Cons:
One thing I wish could happen for the school is that things like the weight room and even the gymnasiums would be open after school as it would give students that might not have P.E in their semester and can't exercise outside of school for some physical activity. Yes the students could join one of the school team sports for physical activity. But some students may not have time for the team sports and so maybe leaving the weight room/gymnasiums open for an hour after school would be beneficial for students.

Super Moon

So, what makes a supermoon different?
Some lunar perigees are closer than others. The shape of the Moon’s orbit changes over time (thanks to the gravitational influence of the Sun and the other planets).
Extreme perigees and apogees, or the most distant point in the orbit, happen on a predictable basis. Something that’s out of the ordinary: Having a full moon at the same time as an extreme perigee.

Blue Moon

"Once in a blue moon..." means seldom or absurd.
But, believe it or not, sometimes the moon really does turn blue, usually after volcanic eruptions or major forest fires. Volcanoes and wildfires fill the air with ash and dust. If the airborne particles are just the right size--about 1 micron (one millionth of a meter) wide--they act like a color-filter, tinging the moon blue. Clouds of water droplets, ice crystals or fine-grained sand can do the same thing.
There are other reasons for odd-looking moons, notes atmospheric optics expert Les Cowley. "Our eyes have automatic 'white balances' just like digital cameras. Go outdoors from a cosy cabin lit by an oil lamp (yellow light) and the moon will appear blue until your eyes adjust."

So, why does the Moon turn red?
A total lunar eclipse happens when the Moon travels through the Earth's umbra and blocks all direct sunlight from illuminating the Moon's surface. However, some sunlight still reaches the lunar surface indirectly, via the Earth's atmosphere, bathing the Moon in a reddish, yellow, or orange glow.
As the Sun's rays pass through the atmosphere, some colors in the light spectrum—those towards the violet spectrum—are filtered out by a phenomenon called Rayleigh scattering. This is the same mechanism that causes colorful sunrises and sunsets. Red wavelengths are least affected by this effect, so the light reaching the Moon's surface has a reddish hue, causing the fully eclipsed Moon to take on a red color.
