blueshift , auch: blue shift

By then we were getting a detectable blueshift off the drive flame.

With considerable force, I might add-look at the blueshift on that inside shell!

Doppler blueshift is caused by movement of a source toward the observer.

For light, this causes a shift in colour towards the blue end of the spectrum called a blueshift.

Doppler blueshift is used in astronomy to determine relative motion:

Nearby stars such as Barnard's Star are moving toward us, resulting in a very small blueshift.

If the observer is at a lower gravitational potential than the source, a gravitational blueshift can be observed instead.

See the formula section below for some basic interpretations that follow when either a redshift or blueshift is observed.

On the other hand, General Relativity predicts a gravitational blueshift of:

Thus the velocity can be measured from the amount of redshift (or blueshift) of the star's spectrum.

Blueshift is most commonly caused by relative motion toward the observer, described by the Doppler effect.

Instead, the blueshift is thought to be evidence for the large range in velocities of objects within the Virgo Cluster itself.

It displays a blueshift, as it is approaching the Milky Way at 287 km/s.

A spectroscopic comparison shows a large blueshift for the quantum dots of 0.85 eV.

The Doppler effect for electromagnetic waves such as light is of great use in astronomy and results in either a so-called redshift or blueshift.

Pirates of the Great Salt Lake is a film made in 2006 by Blueshift Entertainment.

In astronomy, a blueshift is a decrease in electromagnetic wavelength caused by the motion of a celestial object toward an observer.

A blueshift is any decrease in wavelength (increase in frequency); the opposite effect is referred to as redshift.

Redshift (and blueshift) may be characterized by the relative difference between the observed and emitted wavelengths (or frequency) of an object.

The blueshift was originally used to argue that Messier 90 was actually an object in the foreground of the Virgo Cluster.

After z is measured, the distinction between redshift and blueshift is simply a matter of whether z is positive or negative.

Steelscape released its latest EP titled Blueshift in mid-2009.

When the observer looks forward (right on the grid), points appear green, blue, and violet (blueshift) and grid lines appear farther apart.

Some of the nearest galaxies are moving very slowly towards us (that is, the light from them shows a blueshift) but that is a purely local effect.

Doppler blueshift of distant objects (high z) can be subtracted from the much larger cosmological redshift to determine relative motion in the expanding universe.
