What is a sentence using astronomer?
The astronomer studied distant galaxies using a powerful telescope.
How do scientist use ultraviolet light to study galaxies?
Scientists use ultraviolet (UV) light to study galaxies because it provides information about the hottest and most energetic processes occurring within them. UV observations can reveal the presence of young, massive stars, as these emit significant amounts of UV radiation. Additionally, UV light helps in understanding the composition and behavior of interstellar gas and dust, as well as the formation and evolution of galaxies over time. Instruments like the Hubble Space Telescope and the upcoming James Webb Space Telescope are equipped to capture UV wavelengths, enabling detailed studies of distant galaxies.
What does the light from distant galaxies show red shift?
The light from distant galaxies shows redshift because the universe is expanding. As the galaxies move away from us, the light they emit gets stretched, causing its wavelength to increase and shift towards the red end of the spectrum. This redshift can help scientists determine the velocity at which galaxies are moving away from us and provide insights into the expansion of the universe.
What is an instrument used observe distant objects with the eyes?
A telescope is an instrument used to observe distant objects, such as stars, planets, and galaxies, with the eyes. Telescopes gather and focus light to provide a magnified view of celestial objects. They come in different types, such as refracting telescopes and reflecting telescopes.
Which instrument has been used to detect the oldest most distant objects in the solar system?
The Hubble Space Telescope has been used to detect the oldest and most distant objects in the solar system. Its powerful cameras and instruments help astronomers study these objects, such as distant galaxies and stars, by capturing their light and providing valuable insight into their formation and evolution.
How can you view the galaxies?
To view any distant object in space you need a basic $150 telescope.

When the ultraviolet light from hot stars in very distant galaxies finally reaches us what form does it reach the Earth in?
visible light
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
What does the light from distant galaxies show red shift?
The light from distant galaxies shows redshift because the universe is expanding. As the galaxies move away from us, the light they emit gets stretched, causing its wavelength to increase and shift towards the red end of the spectrum. This redshift can help scientists determine the velocity at which galaxies are moving away from us and provide insights into the expansion of the universe.
What type of data does a refracting telescope collect?
A refracting telescope collects light data, which is then focused and magnified by the curved lenses or mirrors inside the telescope. This light data allows astronomers to observe distant objects such as stars, planets, and galaxies.
The visible part of distant galaxies is the galaxies what?
The "nucleus".
What is huble telescope?
The Hubble Space Telescope is a powerful telescope that orbits Earth and captures images of distant galaxies, stars, and other celestial objects. It has provided significant contributions to our understanding of the universe and has been in operation since 1990.
Telescope in a sentence?
The observatory had not yet opened, so we waited outside until it did.
