What else can I help you with?
How do radio waves help astronomers?
They are simply one more way to observe distant objects and events.
Why do astronomers find it difficult to locate extrasolar planets with telephones?
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
Reasons why astronomers have difficulty looking at distant stars except?
Light years of dust lanes obscure the view of distant stars in visible light. However, radio telescopes can penetrate the dust and can detect (in the x-ray and infrared spectra) the stars in the core of our galaxy.They don't understand how redshift affects stars.
Which forms of electromagnetic radiation can interfere with the work of astronomers?
Light pollution from urban areas and artificial sources like street lights can interfere with astronomers' ability to observe celestial objects clearly. Additionally, radio waves from telecommunications and other sources can disrupt radio telescopes that astronomers use to study the universe.
What does the Astronomers use to observe the sky?
a stethoscope
Which planet rings were discovered in 1977 when the planet occulted a distant star?
The rings of Uranus were discovered in 1977 when the planet occulted a distant star. This event allowed astronomers to observe a series of fading and brightening of the star's light, indicating the presence of rings around Uranus.
How do astronomers observe the spiral of the milky way?
by eyes
What lab tool is used to observe objects that are far away?
A telescope is typically used to observe objects that are far away. Telescopes use lenses or mirrors to gather and focus light, allowing astronomers to see distant objects such as stars, planets, and galaxies more clearly.
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
What is a device that is used to observe distant objects?
A telescope.
What instrument is used to view objects in space?
A telescope is commonly used to view objects in space. Telescopes collect and focus light from distant objects, enabling astronomers to observe and study celestial bodies such as stars, planets, and galaxies.
