Difference between Astronomical spectroscopy and Dark matter

Astronomical spectroscopy vs. Dark matter

Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light and radio, which radiates from stars and other celestial objects. Dark matter is a theorized form of matter that is thought to account for approximately 80% of the matter in the universe, and about a quarter of its total energy density.

Similarities between Astronomical spectroscopy and Dark matter

Astronomical spectroscopy and Dark matter have 25 things in common (in Unionpedia): Andromeda Galaxy, Astronomical spectroscopy, Black hole, Electromagnetic radiation, Electromagnetic spectrum, Electron, Fritz Zwicky, Galaxy, Galaxy cluster, Hubble's law, Hydrogen line, Local Group, Milky Way, Planet, Proton, Quasar, Redshift, Solar System, Spectral line, Spectrograph, Spiral galaxy, Star, Supernova, White dwarf, X-ray.

Andromeda Galaxy

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way.

Black hole

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

Electromagnetic radiation

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space-time, carrying electromagnetic radiant energy.

Planet

A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.

Spectral line

A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.

Spiral galaxy

Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae(pp. 124–151) and, as such, form part of the Hubble sequence.
