The Achievements of Edwin Hubble

The Achievements of Edwin Hubble

When you hear the name “Hubble,” you might think of the NASA/ESA Hubble Space Telescope. But, decades before this telescope was built, Dr. Edwin Powell Hubble revolutionized the field of astronomy. This video looks at the life and work of this brilliant American astronomer for whom the Hubble Space Telescope is named.

Discovering Exoplanets From Transits

Discovering Exoplanets From Transits

Much can be learned when a planet crosses between its host star and Earth. This video describes how astronomers get information about planets beyond our solar system using such transits. The video also introduces sophisticated technologies that study exoplanets—specifically, the Hubble Space Telescope and James Webb Space Telescope.

Henrietta Leavitt: The Woman Who Measured the Universe

Henrietta Leavitt: The Woman Who Measured the Universe

Born in 1868, Henrietta Leavitt was an astronomer ahead of her time, whose work helped to revolutionize our understanding of the universe. While working at Harvard Observatory, Leavitt began to study stars of fluctuating brightness. This video describes her crucial observation about variable stars, which gave astronomers a new way to measure distances, ultimately leading to such impactful discoveries as the expansion of the universe.

How the First Stars Transformed the Universe

How the First Stars Transformed the Universe

Immediately after the universe started with the big bang, the cosmos was dark. Only the first stars appearing millions of years later brought light. These first stars and their radiation drastically changed the universe during what is known as the epoch of reionization. This video talks about this important time, what the Hubble Space Telescope has shown us so far, the open questions, and what we can expect from future space missions.
