The Electromagnetic Spectrum Poster
Learn about the different wavelengths in the electromagnetic spectrum, including those that are invisible to the human eye, with this poster, exclusively from Astronomy magazine.
The electromagnetic (EM) spectrum consists of all forms of light. And, as it turns out, most of the universe is invisible to the human eye. Luckily, astronomers can use telescopes to peer into other EM wavelengths — from the radio waves that pierce through dense interstellar dust to the ultraviolet light of stellar nurseries to the gamma rays that stream from supernovae and colliding stars Learn about the wavelengths, frequencies, and visible spectrum of common (and uncommon) things around us.

The Space Store ships packages every business day. We ship worldwide and use US Postal and UPS. We pass on our discounted US Postal and UPS rates to you. We further have set the International US Postal Rates 20% below that rate, to help with shipping costs.
All International shipments may have customs, duties or taxes added, to your order. The recipient of the package is responsible for these costs. Please contact your local customs or Postal Authorities, to know what these fees may be.
Some of our products are shipped directly from the supplier to our customers. Depending on the location of the particular supplier, the shipment may take up to ten days.
For 'oversized packages' and custom models, ACTUAL SHIPPING charges will apply and NOT what the shopping cart shows for shipping. The cart cannot compute over-sized packages. You will be notified what the shipping options and pricing will be.
CUSTOMS / DUTIES / TAXES
International orders likely will have customs, duties and / or taxes imposed on your shipment, before receiving your package. All of these costs are the customers responsibility. We are required to fill out the forms when we ship your package. We ALWAYS lower the price, near or cost, as to help reduce what may be imposed and charged to our customers.
