Euclid Space Telescope

Why is it in the news?

  • The Euclid space telescope recently released its first images.

Euclid’s Mission (led by the European Space Agency (ESA))

  • Euclid’s primary goal is to map the distribution of dark matter and dark energy in the Universe. It will achieve this by observing the shapes and distribution of galaxies and galaxy clusters.

Significance

  • Understanding dark matter and dark energy is crucial for comprehending the fundamental properties and fate of our Universe.
  • Euclid’s observations will contribute to advancing our knowledge of these enigmatic components of the cosmos.
Composition of the Universe: The Universe is composed of different components:

路聽聽聽聽聽聽 Normal matter, which includes the visible matter we can observe, constitutes about 5% of the Universe.

路聽聽聽聽聽聽 Dark matter, an invisible substance, makes up about 25% of the Universe.

路聽聽聽聽聽聽 Dark energy accounts for approximately 70% of the Universe’s composition.

 

Dark Matter

路聽聽聽聽聽聽 Unlike normal matter, dark matter does not interact with the electromagnetic force.

路聽聽聽聽聽聽 Dark matter neither absorbs, reflects, nor emits light, making it extremely challenging to detect.

 

Dark Energy

路聽聽聽聽聽聽 Dark energy is a mysterious energy source responsible for the accelerated expansion of our Universe.

路聽聽聽聽聽聽 Its nature and properties remain largely unknown, and it’s the subject of intensive scientific study.
