A layer of liquid water may be present at the core-mantle boundary.

Most pallasites are believed to be derived from the core-mantle boundary.

The presence of heterogeneous features along the core-mantle boundary might have a bearing on this theory.

What is the nature and heterogeneity of the lower mantle and core-mantle boundary?

These are postulated to comprise columns of hot material that rise from the core-mantle boundary.

Seismology in particular is heavily relied upon for information about the deep mantle near the core-mantle boundary.

These and other observations have led to the obvious speculation that plumes arise at the core-mantle boundary.

The D" layer at the core-mantle boundary separates the mantle from the core.

The core-mantle boundary is a strong thermal (temperature) discontinuity.

In discussing the core-mantle boundary the two scientists avoided taking sides on whether that is where the plumes originate.

The most prominent thermal contrast known to exist in the deep ( 1000 km) mantle is at the core-mantle boundary.

There is no other known major thermal boundary layer in the deep Earth, and so the core-mantle boundary was the only candidate.

The source of mantle plumes, is postulated to be the core-mantle boundary at 3,000 km depth.

"Nobody's proved that helium-3 is from the core-mantle boundary," Dr. Anderson said in an interview.

One of the hypotheses is this is the so-called D"-layer at the core-mantle boundary.

If the ice contains enough ammonia or other antifreeze, Titania may possess a liquid ocean layer at the core-mantle boundary.

Hot mantle at the core-mantle boundary rises while cool mantle sinks, causing convection cells to form.

One suggests that they are due to hot mantle plumes that rise as thermal diapirs from the core-mantle boundary.

He also worked on determining the depth of the core-mantle boundary as well as other properties of the interior of the earth.

Slabs have been imaged down to the seismic discontinuities between the upper and lower mantle and to the core-mantle boundary.

Seismic data will also give scientists more understanding and insight into the lower mantle and the Earth's core, as well as activity at the core-mantle boundary.

Pallasites were once thought to originate at the core-mantle boundary of differentiated asteroids that were subsequently shattered through impacts.

Because there is little material transport across the core-mantle boundary, heat transfer must occur by conduction, with adiabatic gradients above and below this boundary.

However, seismic tomography rejects this hypothesis, as it shows that the plume beneath the Hawaii hotspot extends to the core-mantle boundary.

Similar comments can be made about the cosmic microwave background.

He found part of the cosmic microwave background radiation in 1964.

We check that against the cosmic microwave background, and it seems to hold.

For more information, see Discovery of cosmic microwave background radiation.

This is far less than the 2.7 K produced by the cosmic microwave background.

Another reference frame is provided by the Cosmic microwave background.

It was designed to measure the cosmic microwave background radiation.

Through their measurements of something called "cosmic microwave background radiation."

It started operations in 1999 to study the cosmic microwave background radiation and ran until 2008.

Other ground and balloon based cosmic microwave background experiments are ongoing.

Called the cosmic microwave background radiation, it was discovered accidentally in 1965.

In 2003, observations of the cosmic microwave background confirmed this discovery.

The light which constitutes the cosmic microwave background comes from the surface of last scattering.

The cosmic microwave background radiation was also first detected using radio telescopes.

The cosmic microwave background radiation observed today is "the most perfect black body ever measured in nature".

The cosmic microwave background was initially thought to be isotropic-it's the same where ever you look.

In some ways it is analogous to the cosmic microwave background, but at shorter wavelengths.

With the formation of neutral hydrogen, the cosmic microwave background was emitted.

This produces a "shadow" in the observed cosmic microwave background at some radio frequencies.

On 21 March 2013, the mission's all-sky map of the cosmic microwave background was released.

The best good guess of the Universe's age is 13.73 0.12 billion years old, based on what was seen of the cosmic microwave background radiation.

Recently the telescope was able to detect tiny fluctuations in the cosmic microwave background radiation.

The cosmic microwave background radiation has proven to be fertile ground for cosmologists.

These photons are still traveling today and can be detected as the "cosmic microwave background radiation."

The accidental discovery of cosmic microwave background radiation is a major development in modern physical cosmology.

It had only 45 seats, compared to the previous 52 in Cmb 13.

The CMB would then turn hard over and get out of its path.

By 1874, most significant deposits in the CMB had been found.

The line received two Cmb 13 diesel multiple units in 1927, and a third in 1930.

Without it, the CMB cannot be seen across all its frequency range.

Oh, and cmb is right, nursery rhymes are evil.

In 1927, Cmb 13 diesel multiple units were taken into use, this increasing the number of halts.

This should be more than enough data to get a very clean picture of the CMB.

This is often taken as the "time" at which the CMB formed.

I'm fairly skeptical about anyone trying to get anything out of the CMB right now.

These called for the CMB to be scanned across the full sky at least twice.

Since then, astronomers have tried to detect and interpret the CMB.

As for inflation, there are some hints that one might be able to see its effects in the CMB.

He is known especially for his work on the cosmic microwave background (CMB).

In addition the CMB provides a measurement of this scale to high accuracy.

CMB experiments have now seen this distinctive scale in temperature and polarization measurements.

"The CMB is isotropic to about one part in a hundred thousand.

Actually CMB had already withdrawn several in the 1990s.

Cosmic inflation is also necessary to address the "horizon problem" in the CMB.

This would leave an imprint on the CMB.

Posted by cmb on July 10th, 2004.

Molybdenum deposits in the CMB are of continuing interest.

The CMB was, in essence, the radiation signature of the early, expanding universe.

Another reference frame is provided by the cosmic microwave background (CMB).

This value can be calculated independently from the detailed structure of CMB fluctuations.
