We Found One of the Oldest Galaxies Ever!

The video discusses the discovery of one of the oldest galaxies, G 0983808, which formed 12.8 billion years ago. It highlights the role of the Large Millimeter Telescope (LMT) in observing distant galaxies and explains the concept of redshift and gravitational lensing. Additionally, it introduces a new method for finding habitable exoplanets by detecting atmospheric beacons created by stellar storms, which could significantly reduce observation time. This method could help identify planets with Earth-like atmospheres using smaller telescopes.

What is the significance of the galaxy G 0983808 in astronomical studies?

• It is the largest galaxy ever discovered.

• It is the oldest galaxy ever discovered.

• It is the third oldest galaxy ever discovered.

• It is the closest galaxy to Earth.

How does the Large Millimeter Telescope (LMT) contribute to the study of distant galaxies?

• By capturing sound waves from galaxies.

• By measuring the temperature of galaxies.

• By using visible light to observe galaxies.

• By calculating the distance of galaxies using redshift.

What is the role of gravitational lensing in observing distant galaxies?

• It magnifies the galaxy, making it appear brighter.

• It alters the shape of the galaxy.

• It changes the color of the galaxy.

• It increases the speed of light from the galaxy.

What is the new method for finding habitable exoplanets based on?

• Detecting water on the planet's surface.

• Searching for atmospheric beacons of life.

• Measuring the planet's temperature.

• Observing the planet's orbit around its star.

Which molecules are considered atmospheric beacons of life?

• Hydroxyl and nitric oxide

• Helium and hydrogen

• Carbon dioxide and methane

• Sulfur dioxide and nitrogen
