Hubble telescope finds most distant star ever seen

The video discusses a distant star observed by the Hubble Telescope, located 9 billion years from Earth. The star was seen due to gravitational lensing, where starlight is bent by a galaxy's gravity. The star, a luminous blue supergiant, is similar in size to the sun but much hotter. Researchers confirmed it wasn't a supernova and tested a dark matter theory involving primordial black holes. However, the theory wasn't supported as different light patterns would have been observed if black holes were present.

What phenomenon allows the Hubble Space Telescope to observe distant stars by bending and magnifying their light?

• Stellar Parallax

• Gravitational Lensing

• Cosmic Inflation

• Redshift

What is the star observed by Hubble believed to be?

• A luminous blue supergiant

• A white dwarf

• A neutron star

• A red dwarf

Why was the star not considered a supernova?

• It was too far away

• It was too small

• It was not exploding

• It was not bright enough

What theory did astronomers test using the star's cluster?

• General Relativity

• Quantum Gravity

• Dark Matter Theory

• String Theory

What would Hubble have observed if primordial black holes were present?

• A supernova explosion

• A different light pattern

• A redshift in the light

• A gravitational wave
