What are some characteristics of stars?

• Characteristics of stars include mass, luminosity, temperature, color, size, and spectral type.

• Density, shape, age

• Distance, speed, composition

• Brightness, rotation, atmosphere

What are some characteristics of galaxies?

• Galaxies do not vary in shape or size

• Characteristics of galaxies include vast systems of stars, gas, dust, and dark matter, various shapes and sizes like spiral, elliptical, and irregular, and organization into clusters and superclusters.

• Galaxies are made up of only gas and dust

• Galaxies are small systems of stars

How does Betelgeuse contribute to the study of stars?

• Betelgeuse is a planet with no relevance to the study of stars

• Betelgeuse is a red supergiant star that is easily observable in the night sky, making it a valuable target for studying stellar evolution, supernova explosions, and the life cycle of massive stars.

• Betelgeuse is a comet that moves too fast to be observed for research purposes

• Betelgeuse is a black hole that absorbs all light, making it impossible to study other stars

What makes Alcyoneus unique among galaxies?

• It is the smallest known galaxy by volume.

• It is the only galaxy with a triangular shape.

• It is the largest known galaxy by volume.

• It is the oldest known galaxy in the universe.

How do exoplanets differ from planets in our solar system?

• Exoplanets orbit stars within our solar system.

• Exoplanets orbit stars outside our solar system, while planets in our solar system orbit the Sun.

• Exoplanets do not have atmospheres, unlike planets in our solar system.

• Exoplanets are not made of the same materials as planets in our solar system.

What technologies are used to discover exoplanets?

• Gravitational waves method

• Thermal imaging

• Spectroscopy

• Transit method, Radial velocity method, Direct imaging, Microlensing, Astrometry
