Although the emission frequency of the more distant objects becomes lower due to the expansion of the universe, the ALMA Telescope is designed to receive millimeter waves in a frequency range lower than submillimeter waves observed this time, which means this identification method can be applied to objects even 10 billion light years away and will be a competent observation method in the ALMA Era when there will be a dramatic advancement in the research of distant galaxies.

New observations with the Atacama Large Millimeter / submillimeter Array (ALMA) radio telescope in Chile show that the planet, located about 550 light - years away from Earth in the constellation Chamaeleon, is surrounded by a protoplanet - like disk of gas and dust — which is a distinctive feature of young stars, not planets.

Stellar light absorbed by dust is reradiated from the dust as millimeter / submillimeter waves.

That altitude is above the primary part of the atmosphere that blocks infrared light, which means the telescope can observe at wavelengths longer than the ones we see in our Disk Detective WISE data, but shorter than the submillimeter wavelengths we've observed at with the James Clerk Maxwell Telescope.
