In poetry:

"As waves in stillest waters,
As stars in noonday skies,
All that wakes to noble action
In his noon of calmness lies.

The sky grew dark:
The little bark
Felt all the waves awaking from their sleep.

"Skies with billows closely spun:
"Feeling but the wave that leaps
"Closest to it in the sun."

In the days that had gone by,
I had stood on that bridge at midnight
And gazed on that wave and sky!

No star was in the sky,
The wind it waved the willow boughs,
The stream flowed quietly.

Doth home's green isles descry,
And, vainly longing, gazes o'er
The waste of wave and sky;

In science:

The relative timing offset between the arrival time of a gravitational wave at multiple sites encodes the ma jority of the information about location in the sky (of course additional information is contained in the antenna beam patterns F+,× ).
Bayesian coherent analysis of in-spiral gravitational wave signals with a detector network
All-sky search for periodic gravitational waves in LIGO S4 data, Abbott B et al. (The LIGO Scientific Collaboration), Phys.
On blind searches for noise dominated signals: a loosely coherent approach
An electromagnetic field (EMF) propagating as a transverse plane wave, arriving from any given direction on the sky (cid:126)σ , can be instantaneously characterized by a two-vector of complex amplitudes (cid:126) = (x , y )T .
Element gain drifts as an imaging dynamic range limitation in PAF-based interferometers
The idea of using timing data for a number of pulsars distributed on the sky to detect gravitational waves was first proposed by Hellings & Downs [114].
Binary and Millisecond Pulsars at the New Millennium
An experiment that integrates more deeply on a smaller region of sky can improve the sensitivity to the inflationary gravitational-wave background by almost two orders of magnitude.

An important distinction between gravitational and electromagnetic astronomy is the natural all-sky coverage that gravitational waves provide.

These acoustic waves are seen today in the temperature fluctuations of the microwave background as well as in the distribution of galaxies on the sky.
Lepton Photon Symposium 2005: Summary and Outlook
The other parameters affecting the gravity wave amplitude are the binary inspiral system’s sky position and orbital plane inclination angle, the interferometer orientation, and the polarization of the wave.

This experiment represents the best limit to which the gravitational waves can be detected with the TE correlation. A space-based experiment with access to the full sky is the closest to this experiment.
CMB Temperature Polarization Correlation and Primordial Gravitational Waves II: Wiener Filtering and Tests Based on Monte Carlo Simulations
Gravity wave signals from the reionized plasma have negligible contamination from lensing but, because of the needed full-sky coverage, larger foregrounds to deal with.
The Cosmic Microwave Background for Pedestrians: A Review for Particle and Nuclear Physicists
The accurate measurement of the parameters specifying the relic gravitational waves, e.g. the spectral index nt , depends on the full-sky observations of the CMB B-mode polarization field with the sensitive experiments [35–38].
Testing inflationary consistency relations by the potential CMB observations
For a given gravitational-wave background, the values of S/N and ∆nt mainly depend on two experimental quantities: the total noise level of the experiment and the surveyed sky area.
Testing inflationary consistency relations by the potential CMB observations
It has been noticed that the well detection of gravitational waves needs a full-sky observation by the high-sensitivity detectors.
Testing inflationary consistency relations by the potential CMB observations
LIGO alone, with its two sites which have parallel arms, will be able to detect an incoming gravitational wave, measure one of its two waveforms, and (from the time delay between the two sites) locate its source to within a ∼ 1o wide annulus on the sky.
Gravitational Radiation -- A New Window Onto the Universe
Searches for periodic gravitational wave signals from neutron stars are conventionally classed as blind, directed or targeted. A search is blind if no source parameters (such as sky position or spin evolution) are known a priori, so that the size of the parameter space to be explored is maximal.
