The largest telescope in the world is located in the Canary Islands.

Known as the Gran Telescopio Canarias (GTC), this massive telescope boasts a primary mirror measuring 10.4 meters in diameter. Situated at the Roque de los Muchachos Observatory, it provides astronomers with unparalleled views of the universe.

Astronomers study cosmic microwave background radiation to understand the early universe.

Cosmic microwave background radiation is the afterglow of the Big Bang, and by studying its patterns and fluctuations, astronomers can gain insights into the structure and evolution of the universe in its infancy.

Astronomers have calculated the age of the universe to be approximately 13.8 billion years old.

Through meticulous observations and scientific calculations, astronomers have estimated the age of the universe to be around 13.8 billion years, giving us a glimpse into the immense timeline of cosmic history.

The Hubble Space Telescope has captured breathtaking images of distant galaxies.

Since its launch in 1990, the Hubble Space Telescope has provided us with awe-inspiring views of galaxies millions and even billions of light-years away. Its images have deepened our understanding of the vastness and beauty of the universe.

Astronomers use spectroscopy to analyze the composition of celestial objects.

Spectroscopy is a technique that allows astronomers to examine the light emitted or absorbed by stars, galaxies, and other objects. By studying the unique signatures present in the spectra, they can determine the chemical composition and physical properties of these cosmic entities.

The first black hole photo was captured in 2019.

In a groundbreaking achievement, astronomers captured the first-ever image of a black hole in April The black hole, located in the center of the M87 galaxy, was revealed by the Event Horizon Telescope, an international collaboration of observatories.

Astronomers have discovered evidence of dark matter in the universe.

Dark matter is a mysterious substance that does not interact with light but exerts gravitational effects on visible matter. Through careful observations and simulations, astronomers have found compelling evidence for the existence of dark matter, which plays a crucial role in determining the large-scale structure of the universe.

Astronomers are constantly searching for signs of extraterrestrial life.

With the discovery of potentially habitable exoplanets and advances in technology, astronomers are actively engaged in the search for extraterrestrial life. They use various methods, such as studying the atmospheres of exoplanets and listening for radio transmissions from other civilizations.
