Deflated Supermoon | Bad Astronomy | Discover Magazine:

This amazing shot was taken by astronaut André Kuipers from the International Space Station on May 5, 2012, as the perigee full Moon set behind the Earth’s limb. The Earth’s atmosphere bends light from the Moon, acting like a lens, pushing the bottom part of the Moon up into the top.

So, tonight is the so-called Supermoon, when the Moon happens to be full at the same time it’s at perigee, the point in its orbit closest to the Earth. This makes it somewhat larger and brighter than normal, and that’s getting a lot of attention in the press. I pointed out a few days ago that in reality, you almost certainly won’t notice the difference between this full Moon and any other, mostly because the difference is small, and our eyes and brain are terrible at judging things like that without something to directly compare it to.

The Supermoon stuff? AGAIN? | Bad Astronomy | Discover Magazine:


You may’ve seen some folks writing about this weekend’s so-called Supermoon. I suppose I’m not surprised, but it’s still irritating. Why? Because it’s just hype (and to get this out of the way immediately, will have no real effect on the Earth, either). Here’s the scoop.

This weekend, on the night of May 5/6, the Moon will be full. This happens every 29 days or so when the Moon is opposite the Sun in the sky, and we see its face fully illuminated.

As it happens, the Moon’s orbit is elliptical, and so sometimes the Moon is a bit closer to the Earth than other times. Every now and again the Moon is full when it’s also closest to Earth — the point in its orbit called perigee. May 5th is one of those times.

Kryptonite for the supermoon | Bad Astronomy | Discover Magazine:

If you believe the mainstream media, you might think this weekend’s "supermoon" will cause earthquakes, volcanoes, bad weather, halitosis, dust bunnies, and hangnails.

Guess what I think of this idea! Hint: check the name of my blog. Got it? Good.

Supermoon Skeptic Check | Bad Astronomy | Discover Magazine:

Every now and again I chat with astronomer Seth Shostak about some astronomical skullduggery as part of the SETI radio show "Are We Alone". The segment is called Skeptic Check, and the latest is now online, where Seth and I apply a little kryptonite to the idea of the "supermoon" causing earthquakes.

Why does the Moon look so huge on the horizon? | Bad Astronomy | Discover Magazine:

If you’ve ever seen the Moon rising over the horizon, looking so fat and looming that you felt like you could fall right into it, then you’ve been a victim of the famous Moon Illusion. And it is an illusion, a pervasive and persuasive one.

So, how does this thing work? Ah, step right up.
