Hubble Space Telescope and White Dwarfs

What enabled astronomers to discover the rare ultra-massive white dwarf?

• Radio wave analysis

• Hubble's infrared observations

• Hubble's ultraviolet observations

• Ground-based telescopes

What unusual element was found in the atmosphere of the white dwarf?

• Helium

• Oxygen

• Carbon

• Neon

What is a possible origin for the presence of carbon in the white dwarf's atmosphere?

• A collision between two white dwarfs

• A nearby supernova explosion

• A black hole interaction

• A single star's evolution

What do researchers hope to learn from studying other white dwarfs?

• The size of the Milky Way

• The speed of light

• The frequency of stellar mergers

• The age of the universe

How might this research impact our understanding of supernova explosions?

• By measuring the speed of supernova remnants

• By improving knowledge of stellar evolution paths

• By predicting the location of future supernovae

• By identifying new types of supernovae
