Sentences with phrase «planet at different wavelengths»

Not exact matches

Since different elements and compounds absorb light at characteristic wavelengths, astronomers can determine what chemicals make up a planet's atmosphere by measuring the relative amounts of light that come in at particular wavelengths.

They determined the planet's radius at 10 different wavelength bands, from 300 - nanometer ultraviolet light to 1000 - nanometer infrared.

The team used the GROND imager at the 2.2 m ESO / MPG telescope of the European Southern Observatory in Chile to observe the planet simultaneously at seven different wavelength bands spanning the optical and near - infrared.

Prior observations of extrasolar planets had detected elements by analyzing light passing through their atmospheres, but Richardson says this is the first measurement of the energy coming directly from the planets at many different wavelengths.

The number of planets discovered at 500 nm (black curve) that could also be detected at longer wavelengths (colored curves), as desired for spectroscopic observations, as a function of telescope aperture size and for two different assumed inner working angles.

The spectrograph produces 18 images at different wavelengths of light, which enables GPI to reject light from nearby stars, which can be up to 10 million times brighter than the planets being studied.

The probes will carry a similar array of spectrometers to those on MESSENGER, and will study the planet at many different wavelengths, including infrared, ultraviolet, X-ray and gamma ray.

[2] Such planets are difficult to observe directly and previous studies at millimeter wavelengths have failed to achieve a sharp view of their inner, planet - forming zones where these different explanations could be put to the test.

I understand the superficial attractiveness behind the proposition that the atmoshpere contains some gases that are largely transparent to incoming solar radiation and therefore the majority of this solar radiation finds its way through the atmosphere to the surface whereupon it heats the surface and this heat is, inter alia, radiated from the surface at a different wavelength at which wavelength the atmosphere (or some gases within the atmosphere) is not transparent such that some of this radiated enerrgy is «trapped» thereby effectively warming the planet.
