Did galaxies exist 900 million years after the Big Bang?

By analyzing new observations from NASA’s James Webb Space Telescope, a team led by Simon Lilly of ETH Zürich in Switzerland found evidence that galaxies that existed 900 million years after the big bang ionized the gas around them, causing it to become transparent.

How has solar power changed the world?

Yet in that short time, solar power has revealed the Sun’s limitless potential to power an increasingly technological society. Since the 1950s, NASA has harnessed the energy of the Sun to power spacecraft and drive scientific discovery across our solar system. Today, NASA continues to advance solar panel technology and test new innovations.

When were solar panels first used in space?

The first two sets of solar arrays used by NASA’s Hubble Space Telescope in the 1990s and 2000s were designed with solar cells mounted to a flexible blanket-like material so they could be rolled up and stowed to fit inside the space shuttle cargo bay for launch.

How old is solar power?

But the practice of converting the Sun’s energy into electricity — what we now call solar power — is less than 200 years old. Yet in that short time, solar power has revealed the Sun’s limitless potential to power an increasingly technological society.

How does NASA use solar energy?

Since the 1950s, NASA has harnessed the energy of the Sun to power spacecraft and drive scientific discovery across our solar system. Today, NASA continues to advance solar panel technology and test new innovations. A portrait of French scientist Alexandre Edmond Becquerel, taken sometime in the mid 1800s.

How did the universe change over millions of years?

Over hundreds of millions of years, the gas cooled. Then, the universe hit “repeat.” The gas again became hot and ionized – likely due to the formation of early stars in galaxies, and over millions of years, became transparent. Researchers have long sought definitive evidence to explain these transformations.
