Sentences with phrase «solar photosphere»

All of the energy produced by interior fusion must travel through many successive layers to the solar photosphere before it escapes into space.

It will do this via high - speed (sub-second timescales) spectroscopic and magnetic measurements of the solar photosphere, chromosphere and corona.

Not exact matches

At its closest it will be within 4 million miles of the roiling solar surface, known as the photosphere.

This interface region between the sun's photosphere and corona powers its dynamic million - degree atmosphere and drives the solar wind.

Just keeping count of the number of spots, for example, led to recognition of the 11 - year sunspot cycle that waxes from «solar minimum,» when very few spots are seen, to «solar maximum,» when great conglomerations of planet - size splotches pockmark the photosphere, or visible surface of the sun.

The older idea that acoustic waves flowing out of lower levels heats the corona was abandoned in the 1970s, when the Orbiting Solar Observatory 8 spacecraft did not see such waves in the chromosphere, the layer just above the photosphere (the apparent «surface» of the sun in visible light).

It has long been suspected that turbulent motions in the lower solar atmosphere are propagated outward as waves in some form, which ultimately shock the thin atmosphere above the surface (the photosphere).

Total solar eclipses, seen from Chile on April 16, 1893 (left) and from Mexico on March 7, 1970 (right), reveal the sun's powerful corona, streaming from its photosphere at temperatures of more than 1,000,000 degrees F.

To see what sunspots looks like using modern instrumentation, here are two images of the sun's photosphere, taken by the Solar and Heliospheric Observatory (a joint project of NASA and the European Space Agency).

HMI is an instrument designed to study oscillations and the magnetic field at the solar surface, or photosphere.

To carry out novel investigations based on spectro - polarimetric observations with ground - based and space solar telescopes, with emphasis on the study of the magnetic field in chromospheric and coronal structures and its coupling with the underlying photosphere.

The corona can be seen only during solar eclipses because it is millions of times fainter than the photosphere.

During solar eclipses it can be seen when the much brighter photosphere is blocked out by the Moon.

The solar atmosphere above that consists of the photosphere, chromosphere, a transition region and the corona.

The solar atmosphere is made up of the photosphere, the chromosphere, a transition region, and the corona.

The parts of the Sun above the photosphere are referred to collectively as the solar atmosphere.

However, in comparison with the solar case, the FIR photosphere of alpha Cen A appears marginally cooler, Tmin = T160mu = 3920 + / -375 K. Beyond the minimum near 160mu, the brightness temperatures increase and this radiation likely originates in warmer regions of the chromosphere of alpha Cen A. To the best of our knowledge this is the first time a temperature minimum has been directly measured on a main - sequence star other than the Sun.

Taking advantage of multi-instrument data sets and building up statistics of these events by correlating the changes of physical parameters will provide a comprehensive picture of these processes from the photosphere to the higher solar atmosphere.

Light at this wavelength originates from the visible solar surface, the photosphere.

This is why (absent sufficient solar or other non-LW heating) the skin temperature is lower than the effective radiating temperature of the planet (in analogy to the sun, the SW radiation from the sun is like the LW radiation, and the direct «solar heating» of the part of the atmosphere above the photosphere may have to due with electromagnetic effects (as in macroscopic plasmas and fields, not so much radiation emitted as a function of temperature).

Region 1263 on the photosphere (the solar surface), near the west limb, produced the event and a few others of lesser magnitude in the past day.

Same for the temperature measurements, what part of the photosphere is the correct solar temperature?
