What else can I help you with?
What type of star are S.E.T.I. scientists aiming their radio telescopes?
the yellow star
What type of radio sounds do radio telescopes hear?
Stars broadcast from x-rays down through infrared, and radio telescopes take advantage of this by tuning in to the emissions, dubbed "radio" to differentiate from "optical" here, not because the star is necessarily being monitored in our "radio" spectrum.
How does a pulsar star get its name?
Pulsar stars get their name from the pulses of radiation they emit as they rapidly rotate. These pulses are detected as regular intervals of electromagnetic radiation, such as radio waves, X-rays, and gamma rays. The word "pulsar" is a combination of "pulsating" and "star."
How are pulsars detected?
Most pulsars are detected purely through luck. Many organizations have radio telescopes constantly scanning the skies for signals, sometimes one picks up a regular periodic signal, if it is properly periodic, we know it's at least a pulsar or a quasar, further research would discern exactly what.
Why are stars not been found during the day time?
Simply because the daylight totally masks the far fainter star-light. They are still there, and radio telescopes can still track stellar radio sources.
Which wavelength range in the electromagnetic spectrum has been the most fruitful in the search for organic molecules in space?
The radio wavelength range has been the most fruitful in the search for organic molecules in space. Radio telescopes have detected complex organic molecules in regions such as star-forming regions, comets, and interstellar clouds, providing valuable insights into the presence and chemistry of organic molecules in space.
What makes a star visible?
The emission of energy in the form of electromagnetic radiation, such as gamma rays, x-rays, ultraviolet rays, infrared radiation, visible light, microwaves, and radio waves. These emissions are all measurable and are also used to determine how far the star is and how fast/far it is moving away from our galaxy based on the expanding universe theory.
How are microwaves from space detected and what do they tell us about the beginning of the universe?
Microwaves from space can be detected from the use of radio telescopes. Microwaves have been used to test the big bang theory, and this Cosmic Microwave Background (CMB) radiation is a form of microwave that "fills" the universe, that is almost exactly the same in all directions and is not associated with any star or object. The CMB radiation is recognized to be radiation left over from the big bang, or during the early stages of development of the universe.
What are the instruments used by the astronomers to study star?
telescopes
What instrument used to gather information about star?
Telescopes?
What are instruments used to study heavenly bodies aside from telescope?
An inclinometer is a tool used to measure the angle at which a star is above the horizon. Combined with a standard compass, you can define or measure a star's position.Nassif A. Dida-agunLordjean Bhanz C. CerboBonnajio D. OlmidoNestor R. Pilapil Jr.
What are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
