Theoretical physicists say that space and time are one thing created by the Big Bang. According to them, nothing happened in the time before the Big Bang because time did not exist. The first Crash Course-Big History video in a 16-part...

Imagine what life might be like in a different galaxy. That's the challenge young scientists take on in a warm-up activity designed to prepare them for a close reading of Ruth Stone's poem "In the Next Galaxy." After class members share...

Add a little color to the universe. Learners recreate images of the galaxies using real data and Photoshop software. They display their images in a Hubble tuning fork diagram by classifying and categorizing their shapes.

Just when is the universe's birthdate? Pupils use previously collected spectra data to find the redshift and radial velocity of supernovas. They then calculate the distance before finally creating a Hubble diagram. Finally, individuals...

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

Do you see what I see? Individuals view eight images from the Hubble Space Telescope and then determine exactly what is being shown in the images. The pictures range from the rings of Saturn to views of billions of galaxies that take up...

Could there really be over 200 billion galaxies? It turns out the number may be closer to two trillion galaxies! A video presentation discusses the existence of galaxies in the universe. The narrator explains how scientists make their...

Take a look at astronomy through the light lens. From radio to gamma, light waves exist in every corner of the universe. An enlightening PowerPoint presentation gives an overview of the different categories of light and then discusses...

Once, scientists believed black holes to be rare, but modern technology is proving otherwise. Using data from the Hubble telescope, scientists create computer models of distant galaxies. They discover super massive black holes in the...

Prepare to be amazed! Look deep into the darkest part of the night sky, courtesy of a video from a vast physics playlist. Young astronomers see hundreds of galaxies through the eye of the Hubble Telescope. 

Think you know a lot about the universe? You may, or may not, be right! Aspiring astrologists examine our ever-expanding universe with a video from the Veritasium playlist. The narrator discusses the observable universe, the time it...

Everyone has a different point of view, even when it comes to the enormity of the universe. Two separate text passages explain the scope of a galaxy, prompting young readers to write an essay about each author's argument and how the...

A star is born! Introduce young astronomers to the characteristics of nebulae in a narrated video. Discover what they are made of, why some reflect light and others glow on their own, and the locations of several notable nebulae. The...

There are so many galaxies in the universe that the vast majority of them are too distant for the human eye to perceive. An astronomy video discusses the Hubble Telescope's Deep Field image from 1995 and the eXtreme Deep Field image...

Scientists classify everything from the smallest cells to the largest galaxies, but how do they decide on a classification system? Scholars use 40 pictures of galaxies taken by the Hubble Space Telescope to sort and try creating their...

Was the universe created or has it always existed? Here is a five-part series about the origin and evolution of our universe. To start, part one looks at celestial objects and allows pupils to discuss and share their knowledge about...

The Hubble Telescope is approximately the size of a school bus, but the new Webb Telescope will be approximately the size of a tennis court. The history of the telescope, from its invention to to what it takes to make one, is the focus...

In 1924, Bose and Einstein predicted a fifth state of matter. The prediction proved to be true in 1995 and is referred to as the Bose-Einstein condensation. This video discusses the concept of matter, all five states of matter, and what...

The most sophisticated mirror in the universe is blurry at room temperature. An informative video discusses the five challenges the mirror had to overcome. It addresses each individually and how it was solved. Then it explains the future...

Explore what it takes to service the Hubble telescope. In the set of three activities, groups investigate several aspects of the Hubble telescope, including robotic arms used during repairs, spacesuits, and extravehicular activity (EVA)...

Scholars are more likely to remember a photograph or a diagram than the text on the same page. How have images shaped our understanding of science? The video highlights images from the work of Copernicus, Darwin, Einstein, the Hubble...

Sal gives an example of where the Hubble telescope looks, as well as the level of detail that the camera can see.
