Objects that are not extremely cold, or very hot, but warm (by space standards). This is because those objects emit radio waves with fairly high intensity, but not too much higher energy radiation, which would interfere.
Quasars
RADAR (RAdio Detection And Ranging)
sattelites
Radio telescope, usually a microwave dish with a movable parabolic reflector.
Radio waves are longer on the electromagnetic spectrum and can penetrate objects because they are less dense. Visible light and infrared light are shorter and therefore too dense to pass through objects.
There are various objects that can be responsible for radio emissions in space. These objects are referred to as astronomical radio sources.

Objects such as pulsars, radio galaxies, supernova remnants, and active galactic nuclei are known to emit radio waves in space. These emissions can be detected by radio telescopes and provide valuable information about the nature and behavior of these cosmic objects.
A radio telescope uses an antenna and receiver to detect radio waves emitted by astronomical objects. These telescopes are essential for studying objects that emit radio waves, such as pulsars, quasars, and radio galaxies.
Yes, a radio telescope is an instrument specifically designed to detect and measure radio waves emitted by celestial objects in space. It is used to study and observe radio emissions from various astronomical sources, providing valuable information about the universe.
Radio telescopes can detect and study radio waves emitted by astronomical objects in space, such as stars, galaxies, black holes, and cosmic microwave background radiation. They provide valuable insights into the composition, structure, and behavior of celestial objects that may not be observable through other wavelengths of light.
Radio waves originate from various sources, including natural phenomena like lightning and astronomical objects, as well as human-made devices such as radios, cell phones, and broadcasting towers.
The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.
All Radio Telescopes form images of astronomical objects using a frequency of the electromagnetic spectrum (radio waves) that human eyes can not detect. This tells us things about these regions of space that we cannot learn in other ways.
A radio telescope uses an antenna and receiver to detect radio waves emitted by astronomical objects. Unlike optical telescopes that observe visible light, radio telescopes capture radio frequencies, allowing astronomers to study phenomena such as pulsars, quasars, and cosmic microwave background radiation. The collected data is then processed to create images or spectra of the observed objects.
When several radio telescopes are wired together, the resulting network is called a radio interferometer. This system allows for the combination of signals from multiple telescopes to achieve higher resolution images of astronomical objects, effectively simulating a larger telescope. The technique enhances sensitivity and detail in radio observations.
Radio telescopes and Keck telescopes differ primarily in the type of electromagnetic radiation they observe. Radio telescopes detect radio waves emitted by celestial objects, allowing astronomers to study phenomena like pulsars and cosmic microwave background radiation. In contrast, the Keck telescopes, which are optical/infrared telescopes located in Hawaii, observe visible and infrared light, enabling detailed imaging and spectroscopy of stars, galaxies, and other astronomical features. This distinction in wavelength leads to different techniques and instruments used in their respective observations.
