Space Travel and Exploration. Happy New Year From Quantum Day! Hubble Space Telescope Calendar 2013. New Space Instrument, K-band Multi-Object Spectrograph (KMOS), Can Observe 24 Objects In Space At The Same Time. A new space instrument was attached to the ESO's Very Large Telescope. The K-band Multi-Object Spectrograph (KMOS) has 24 robot arms that can study and observe 24 objects such as galaxies all at the same time. Space telescopes and instruments study and gather data about the Universe by observing the light emitted by these objects. Stars can be seen by the naked eye because of the light they emit. But as farther the objects are, the light from these objects move from visible light to the infra-red spectrum which is not visible to the eye. This is called the redshift. To explain redshift, it is best to compare it to hearing a police or ambulance siren.

As the siren gets closer, the pitch gets higher, as the siren passes and moves away, the pitch goes lower. This Doppler effect works the same way with light waves, as the object is far away, the wavelength of light gets lower and moves toward the red side of the spectrum. The K-band Multi-Object Spectrograph (KMOS) The James Webb Space Telescope Successor To The Hubble Space Telescope. The James Webb Space Telescope (JWST) to be launched sometime 2018 will be replacing the Hubble Space Telescope. NASA, the European Space Agency, and the Canadian Space Agency have collaborated in the project since 1996. It is built to peer farther into space than the Hubble can and measure and observe objects in space from the early Universe.

Since it's mission is to study objects farther into space, the size, its orbit and the mirrors of the telescope, the instruments on the James Webb Space Telescope are different from those in the Hubble. The mirror of the JWST is 6.5 meters in diameter and will have a five layer sunshield the size of a tennis court. It will be positioned around 1.5 million kilometers (930,000 miles) from the Earth and is designed to work primarily in the infrared range of the electromagnetic spectrum.

Compared to JWST, the Hubble Space Telescope is positioned 353 miles away from the Earth. Four scientific instruments will be placed on the JWST.
