Not exact matches

The puzzle emerged after astronomers measured the cosmic microwave background — a bath of radiation, left over from the Big Bang — and found only slight variations in its temperature across the entire sky.

The next decade, studies of the cosmic microwave background (the relic radiation from the Big Bang) by the Wilkinson Microwave Anisotropy Probe, or WMAP, provided a new way to measure the total amount of dark matter; this is the same technique that the Planck spacecraft built upon to come up with its more precise cosmic bmicrowave background (the relic radiation from the Big Bang) by the Wilkinson Microwave Anisotropy Probe, or WMAP, provided a new way to measure the total amount of dark matter; this is the same technique that the Planck spacecraft built upon to come up with its more precise cosmic bMicrowave Anisotropy Probe, or WMAP, provided a new way to measure the total amount of dark matter; this is the same technique that the Planck spacecraft built upon to come up with its more precise cosmic breakdown.

THE MEANING «Recently the Wilkinson Microwave Anisotropy Probe measured the age of the universe to be 13.7 billion years from the cosmic microwave background,» FreMicrowave Anisotropy Probe measured the age of the universe to be 13.7 billion years from the cosmic microwave background,» Fremicrowave background,» Frebel says.

Researchers used supernovas, cosmic microwave background radiation and patterns of galaxy clusters to measure the Hubble constant — the rate at which the universe expands — but their results were mismatched, Emily Conover reported in «Debate persists on cosmic expansion» (SN: 8/6/16, p. 10).

In its importance for our understanding of — well, everything — measuring such a signal would be even more revolutionary than mapping the cosmic microwave background (CMB), the relic light from when the early universe first cooled to transparency some 380,000 years after the big bang.

The rate of expansion soon after the big bang might also be a little off if we aren't correctly measuring the sizes of fluctuations in the cosmic microwave background.

These gravitational waves we will to detect will almost be the size of visible universe, but we mean, they'll produce signatures, temperature — well, in this case, the polarization of the microwave background — signatures which are at the level, well, the next generation, the best we can imagine doing is getting a 1 [percent] admixture of a signal from gravitational waves compared to the signal of the temperature fluctuations that we, kind of, measure in the universe.

He is not a member of BICEP2, which also measures the cosmic microwave background (CMB), but he had been lecturing on it to his students at Princeton University.

BICEP measures the polarization of the cosmic microwave background and allows scientists to investigate the theory that the universe expanded exponentially in the fraction of a second directly following the Big Bang.

By measuring subtle variations in the cosmic microwave background (CMB), the remnant radiation from the early universe that pervades the sky, WMAP refined the estimated age of the universe (13.7 billion years, give or take), among other key cosmological parameters.

But it turns out we can actually indirectly measure gravity waves by looking out at the cosmic microwave background that's come to us from the big bang and imprinted in there, it turns out for reasons I think I won't talk about here, [is] a signal maybe of the big bang and I've just, in fact, written a bit about how you might be able to entangle that signal.

Recent experiments including BOSS and the Planck satellite study of the cosmic microwave background put the BAO scale, as measured in today's universe, at very close to 450 million light years — a «standard ruler» for measuring expansion.

In addition to measuring the temperature of the cosmic microwave background, Planck can determine its polarization, the direction in which the waves of light vibrate as they move through space.

The UC San Diego scientists measured variations in the polarization of microwaves emanating from the Cosmic Microwave Background — or CMB — of the early universe.

An accurate measurement of the EBL is as fundamental to cosmology as measuring the heat radiation left over from the Big Bang (the cosmic microwave background) at radio wavelengths.

«We are measuring the expansion rate better than at any point since the afterglow of the Big Bang, known as the Cosmic Microwave Background (CMB), and that precision is giving us a hint that maybe we aren't getting what we expected and so maybe the universe isn't quite as we had thought.»

In 2001, the Wilkinson Microwave Anisotropy Probe (WMAP), a NASA spacecraft, began measuring the extremely uniform temperatures of the Cosmic Microwave Background (CMB) radiation from deep space.

But these estimates are rather different from that obtained from the Planck space telescope, which measured radiation from the cosmic microwave background.

NASA's Wilkinson Microwave Anisotropy Probe (WMAP) is currently at this spot measuring the cosmic background radiation left over from the Big Bang.

This program focuses on measuring the polarization of the cosmic microwave background radiation to investigate the first instants of the universe.
