What is a Supermoon Lunar Eclipse?

We’ve told you that on Sept. 27 a supermoon lunar eclipse will occur in the U.S. And much of the world, but what does that mean?

One important note, is that this event can be referred to in many different ways: 

Supermoon Lunar Eclipse

Super Blood Moon

Harvest Moon Eclipse

Supermoon Eclipse

All slightly different names, but apply to the same spectacular event that will occur this weekend. 

Since it’s rare that both a supermoon and an lunar eclipse occur at the same time, let’s break it down. 

1) Supermoon

A supermoon is a full or new moon that falls closest to the fall equinox, and is at its closest approach to the Earth. This results in the moon appearing up to 14% larger in diameter.

2) Lunar Eclipse 

A lunar eclipse occurs when the moon passes directly behind the Earth into its shadow. This can give the moon a red tint.

3) A Supermoon Lunar Eclipse!

The combination of these two events does not happen very often. In fact, since 1900 a supermoon lunar eclipse has only happened 5 times! The last time this occurred was 1982, and if you miss the event this year, your next opportunity won’t come until 2033.

This year, the event will be visible from the Americas, Europe and Africa on the night of Sept. 27. Here’s a full schedule of the supermoon eclipse:

If it’s cloudy in your area on Sept. 27, don’t worry! NASA Television will be providing a live stream of the event, so you can tune in and enjoy the show.

New video on the Hubble Sequence! Had a lot of fun making this one, enjoy!

For anyone interested, this is a lecture we recently helped organise at the University of Glasgow, “Listening to Einstein’s Universe: the hunt for gravitational waves” by Prof. Martin Hendry. I’d suggest giving it a watch it you’re interested, it’s both fun and informative :)

Blood, Part 1 - True Blood: Crash Course A&P #29

Now that we’ve talked about your blood vessels, we’re going to zoom in a little closer and talk about your blood itself. We’ll start by outlining the basic components of blood – including erythrocytes, leukocytes, platelets, and plasma – as well as the basic process of hemostasis that stops bleeding, and how antigens are responsible for the blood type that you have. By the end of this episode, you should be totally prepared for your next blood drive.
