What else can I help you with?
What do you call the kind of telescope that the scientist use?
Scientists typically use optical telescopes to observe and study celestial objects and phenomena in the universe. These telescopes gather and focus light to create detailed images of distant objects, helping scientists to learn more about the universe.
How far away are the farthest objects we can observe?
The farthest objects we can observe are galaxies that are around 13.8 billion light-years away. This distance is governed by the age of the universe, as light from these objects has taken the entire history of the universe to reach us.
Why does electrons happen?
In the first nanoseconds after the big bang there was only light energy in the universe. As the energy spread out and the universe cooled these photons of light energy decayed into a type of lepton called an electron. These are the most common types of lepton we can observe today.
What is the earliest time in the universe that you can directly observe?
The earliest time in the universe that we can directly observe is the cosmic microwave background radiation, which dates back to about 380,000 years after the Big Bang. This radiation provides a snapshot of the universe at that time, when it cooled enough for atoms to form and light to travel freely.
Astronomers use instruments to observe the universe What instruments is used to observe distant stars?
Astronomers primarily use telescopes to observe distant stars. These can be optical telescopes, which capture visible light, or radio telescopes that detect radio waves emitted by celestial objects. Additionally, space-based observatories like the Hubble Space Telescope provide clearer views by avoiding Earth's atmosphere, while instruments like spectrometers analyze the light from stars to determine their composition, temperature, and motion.
What scientific tool do you use to observe organelles?
Either a light microscope or an electron microscope can allow you to observe cell organelles.
How does the fact that light can travel through a vacuum impact our understanding of the universe?
The ability of light to travel through a vacuum allows us to observe distant objects in space and gather information about the universe. This has greatly expanded our understanding of the cosmos, as we can study objects that are millions or even billions of light-years away.
What does observable universe mean?
The observable universe refers to the portion of the universe that can be seen from Earth, limited by the distance light has traveled since the Big Bang, approximately 13.8 billion years ago. This region encompasses all celestial objects whose light has had enough time to reach us, creating a spherical boundary around our planet. Beyond this boundary, there may be more universe that we cannot observe due to the finite speed of light and the expansion of space. The observable universe is estimated to be about 93 billion light-years in diameter.
WHAT TOOL DO YOU USE TO OBSERVE TO MOVEMENTS OF A paramecium?
light mircoscope. you little study island fiend.
About how far away are the farthest observable objects in the universe?
Considering, we can only observe light, the furthest known object is UDFj-39546284 a stellar structure. At the time of observation it was about 13.2 billion light years from us.However, since that time, it is now possibly 32 billion light years from us and getting further away.
What do you observe when the path of light change?
you observe your mom
What instrument would you use if you were in biology class and wanted to observe the nucleus of a cheek cell?
You would use a compound light microscope to observe the nucleus of a cheek cell in biology class.
