Perfect magnets

this is a sea angel (clione limacina), photographed by alexander semenov swimming with its wing like fins in russia’s white sea. these translucent pteropods, measuring only a few centimeters in length, are actually sea snails sans shells. lacking this cumbersome but protective shell, sea angels instead synthesize bad tasting compounds that dissuade predators from eating them.

Textile Art + Science = Crocheted Chemistry

Dallas, TX-based textile artist Lauren Espy just completed crocheting the cutest chemistry set we’ve ever seen. Each handmade piece of amigurumi lab equipment, colorful beakers and test tubes, and a fiery little bunsen burner (our favorite), wears a smiling face that clearly says they’re ready to do some awesome science.

Follow Lauren Espy on Instagram to check out more of her crocheted creations. Espy sells some of her pieces via her Etsy shop, where she plans to list smaller pieces of crocheted chemistry equipment in the near future. So stay tuned!

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.
