Astronomers use this telescope to observe objects in the Solar System and the Milky Way, as well as other galaxies, including the supermassive black holes known as quasars. Astronomers also use the 1. Visit the 1. Astronomers use this telescope to measure the spectrum of light emitted by a wide variety of objects in the Solar System, the Milky Way, and in distant galaxies.

The GMT will consist of seven large mirrors acting in concert as one giant telescope 80 feet across. That large size provides an unprecedented view of the sky and the ability to detect the chemical composition of exoplanet atmospheres. Visit the GMT Website. This observatory will be able to take images of a larger area of the sky in X-ray light with better resolution than any existing telescope, allowing astronomers to study the first supermassive black holes, the hot gas surrounding galaxies as they evolve, and radiation from the earliest stars.
These telescopes are both equipped with instruments to take images and spectra of light from a wide variety of astronomical sources, including exoplanet systems, star-forming regions, supernova remnants, and interacting galaxies.

Pan-STARRS1 data revealed many asteroids, comets, and other previously-unknown moving or variable astronomical objects. SOFIA is a powerful, general-purpose infrared observatory used to study the birth of new stars, planetary nebulas and supernova remnants, the atmospheres of Solar System objects, and many more.
Spitzer Space Telescope Infrared light is the key to studying a wide range of astronomical systems, including newborn stars and planets, dust in distant galaxies, and material swirling around black holes. The Spitzer Space Telescope was launched in and retired in Earth and its neighbors don't orbit within the plane of the galaxy but are instead tipped by about 63 degrees. More than half the stars found in the Milky Way are older than the 4.
Galaxies like ours typically undergo a stellar baby boom , churning out stars in enormous quantities roughly 10 billion years ago. The most common stars in the galaxy are red dwarfs, a cool star about a tenth the mass of the sun.
Once thought unsuitable for potential life-bearing planets because such bodies would have to be too close to meet the criteria, red dwarfs are now considered potential suspects. As late as the s, astronomers thought all of the stars in the universe were contained inside of the Milky Way.
It wasn't until Edwin Hubble discovered a special star known as a Cepheid variable , which allowed him to precisely measure distances, that astronomers realized that the fuzzy patches once classified as nebula were actually separate galaxies.
The mission plans to launch in from McMurdo, Antarctica and should remain in the air between and days, depending on weather conditions.

Now an international This is the first time this detection method has been These rocky worlds have an ultra-thin outer brittle layer and little to no topography. Such worlds These are both important marker of spiral arms in other spiral galaxies we see, so mapping them in our own galaxy can give a clue about the spiral nature of the Milky Way.
There are bright enough that we can see them through the disk of our galaxy, except where the region at the center of our galaxy gets in the way. There has been some debate over the years as to whether the Milky Way has two spiral arms or four.
The latest data shows that it has four arms, as shown in the artist's illustration below. Additional clues to the spiral nature of the Milky Way come from a variety of other properties. Astronomers measure the amount of dust in the Milky Way and the dominant colors of the light we see, and they match those we find in other typical spiral galaxies. All of this adds up to give us a picture of the Milky Way, even though we can't get outside to see the whole thing.
There are billions of other galaxies in the Universe. Only three galaxies outside our own Milky Way Galaxy can be seen without a telescope, and appear as fuzzy patches in the sky with the naked eye. The closest galaxies that we can see without a telescope are the Large and Small Magellanic Clouds.
