There is a good new for astrophiles. The last full moon of 2017 is going to appear a little bigger and brighter than most.
Dec. 3 will bring a supermoon, (mean) a full moon that happens at perigee—the same time that the moon is closest to the earth. this particular occasion, the moon will appear 7 percent larger and 16 percent brighter than usual. Not only will this be the only full supermoon of 2017, it's also going to kick off a series of three full supermoons in a row. The full moons on Jan. 2 and Jan. 31 will be super (one) and even they'll be blue super moons, means the second full moon in a single month.
While some moonwatchers might be getting excited, some people think the hype（炒作）around supermoons isn't all it (regard) as being. A scientist slammed（抨击）the term last year as something made up (complete) and a waste of everyone's time. He acknowledged that supermoons would appear bigger and brighter, but that actually an amateur (observe) wouldn't notice the difference. Another scientist (make) a similar (argue) back in 2012.
If the supermoon makes you want to go out and appreciate the sky's beauty, we say “Go for it.”
