What is the difference betwn Hubble, Chandra, Kepler?

Ayant une révolution autour du soleil légèrement moins rapide que la terre, Kepler s’éloigne donc légèrement de nous. actually orbit the Earth - instead it will sit at the Earth-Sun L2 Lagrange Studying these island worlds will help us understand more about how planetary systems form, evolve, and break apart. “Webb is going to allow us to do this in much more detail and at wavelengths we’ve never explored before. the visible range (in particular in the red and up to the yellow part of the visible spectrum). Son miroir principal a un diamètre de 6.5 mètres (contre 2.5 pour Hubble), et les fans de Star Wars seront immanquablement frappés par sa forme ! as shown in the diagram to the left.

Dans les observations majestueuses d’Hubble, on retrouve également la galaxie M104, aussi surnommée galaxie du sombrero. Nous allons voir leurs différences, mais avant, rapide tour sur les télescopes spatiaux en général. Le principe est simple : Il observe les étoiles, et détecte les infimes variations de luminosité pouvant être causées par le passage d’une planète devant. Because of the time it takes light to travel, the farther away an object is, the farther back in time we are looking. This is the other reason that Webb is not a replacement for Hubble; its capabilities are not identical. This means that the faintest signals from deep space are lost a long time before they even reach us. Ce nouveau télescope est issu d’un partenariat entre la NASA, l’Agence Spatiale Européenne (ESA) et l’Agence Spatiale Canadienne (ASC). Webb will observe mainly in the infrared and will have four research instruments to record celestial source photographs and spectra. Il fait le tour du soleil en 372 jours et se situe derrière la planète bleue. Its larger size also means that the new telescope can detect the faintest amounts of radiation from the farthest reaches of the universe. Also referred to as the successor to the 1990 Hubble Space Telescope, the James Webb Telescope is a big deal. James Webb Telescope vs Hubble: Different Wavelengths. Site Editor: Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Hubble’s sensitive instruments were able to detect light from 13.2 billion years ago – farther than ever before in time and space – and to within 600-700 million years of the Big Bang.

Read on to explore some of the details of what these Our observations are going to tell our community the most efficient way to use Webb.”. This would lend it a superior viewing field, allowing it to see see further back in time. Webb will be a specialist infrared detecting instrument able to delve even further back to within 100-200 million years of the start of our young universe, at a time of great activity. “To go to the earliest galaxies, we needed a bigger mirror, and that bigger mirror had to look at a bigger frequency of light,” astrophysicist Blake Bullock told MSN. The advantage here is that viewing in the near-infrared spectrum can make smaller objects visible and helps us look farther into the universe. Webb will find the first galaxies to form in the early universe, for which it needs extreme sensitivity in the near-IR. Because of the cosmic speed limit, we are always looking at the past form of any celestial object. "Hubble" is a telescope, in the true sense of the word and, again, it operates in space. It tells us that the expansion of the universe means it is the space between objects that actually stretches, causing objects (galaxies) to move away from each other. Hubble is in a very close orbit around the earth,

The wide separation of this young planet from its star means that the team’s observations will be much less affected by the bright glare of the host star. Hubble: James Webb: The Hubble Space Telescope orbits around the Earth at an altitude of ~570 km above it. So it’s going to be vital for understanding how these objects form, and what these systems are like.”.
