They are unified by thinking of them as electromagnetic waves, waves of alternating strength in electric and magnetic fields that all move through space at the speed of light (called c) of 300,000 kilometers per second (186,000 miles per second), eight times around the Earth in the tick of a clock.

A neutron star is the collapsed core of a large (10–29 solar masses) star. Neutron stars are the smallest and densest stars known to exist. Though neutron stars typically have a radius on the order of 10 km, they can have masses of about twice that of the Sun. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past the white dwarf star density to that of atomic nuclei.

X-Ray Visible Light Mid-Infrared Far-Infrared Radio Waves. Ultraviolet Light Visible Light Near-Infrared Radio Waves. Messier 81 (above) is a spiral galaxy. In X-rays we see the bright central core of this galaxy as well as a distant quasar, which appears as a bright knot directly below the galaxy's center. Ultraviolet reveals hot, young stars and multiple spiral.

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

All objects emit radiation. The hotter the object is, the more of that emission is at shorter wavelengths. So, many cool objects emit radiation that is at wavelengths longer than the visual spectrum, so we don't see them as emitting light. But very hot objects emit lots of visible light.

We know what the stars are made of, know of their structures and their lives, only because we are able to observe and analyze their spectra. Unbroken starlight allows us to admire a star's external characteristics; its spectrum allows us to look into its very soul. SUBJECTS.

All objects emit electromagnetic radiation, and the amount of radiation emitted at each wavelength determines the temperature of the object. Hot objects emit more of their light at short wavelengths, and cold objects emit more of their light at long wavelengths.

The amount of light produced by an object at each wavelength depends on the temperature of the object producing the light. Stars hotter than the sun (over 6,000 degrees C) put out most of their light in the blue and ultraviolet regions of the spectrum.

March 2, 2005. Astronomers have detected an unusual, powerful burst of intermittent radio waves emanating from the direction of the center of our galaxy. Now the search is on to trace the source of the mystery radio bursts, or at least find more like it. Was it a dying star burping its last radio emissions?

A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names.
