The European Southern Observatory's Very Large Telescope (VLT)has a new instrument installed today that will help in observing distant galaxies. The Multi Unit Spectroscopic Explorer will help astronomers view far away objects such as galaxies and determine its properties such as mass and chemical composition. It can also capture images of these objects in high resolution 3D.
MUSE is an instrument that measures properties of light such as wavelengths and intensities and combines it with high resolution imaging. By using a technique called integral field spectroscopy, MUSE can study the properties of different parts of an object, measure its mass, and observe its rotation at the same time. With the advanced technology of MUSE in terms of sensitivity, efficiency and resolution, resulting images and data are far ahead of previous spectroscopic imaging.
With MUSE, astronomers can can move through the data and study different views of an object at different wavelengths, just like tuning a television to different channels at different frequencies.
This image above is of the Orion Nebula as imaged by MUSE early this year.
