What do you get when you put a space telescope into operation with another or two space telescopes? Amazing compilation pictures of our universe.
NASA recently highlighted some collaborations among its own Chandra X-ray Observatory and other telescopes, most notably the Hubble Space Telescope, which shows what kinds of images can be produced when looking at the same object at different wavelengths of light.
Galaxy M82 can be seen onboard from Earth, allowing scientists a great perspective whenever star formation occurs, as there is little that blocks our view. Chandra’s observations, visible in blue and pink, show bursts of high temperatures created when the gas is heated supernova explosions. Optical images from the Hubble Space Telescope (shown in red and orange) reveal the shape of the galaxy.
The galactic cluster Abell 2744 includes a lot of superheated gas that glows brightly on X-rays. X-rays are seen in the Chandra data as blue clouds, juxtaposed with Hubble’s optical light and shown in red, green and blue. Clusters of galaxies they are huge collections of galaxies held together by gravity, and these behemoths teach astronomers about the structure of the universe.
Supernova 1987A (SN 1987A)
A supernova explosion on February 24, 1987 is still producing valuable scientific data a generation later. The telescopes are regularly revisited Supernova 1987A to see how its gas and dust transform over the years. Chandra’s data (in blue) shows the supernova shock wave hitting a shell of material about four light-years in diameter surrounding the exploded star. The Hubble view also shows some of the interactions in the optical wavelengths, shown here in orange and red.
Eta Carinae it is a potential supernova location in the future, as it hosts two massive stars orbiting each other and interacting chaotically through gravity and material. Chandra X-ray data here appears in purple, Hubble optical data is displayed in white, and Hubble ultraviolet data is visible in cyan. “Previous eruptions of this star have resulted in an X-ray-emitting hot gas ring approximately 2.3 light-years in diameter surrounding these two stars,” NASA officials he said in a statement released with pictures.
Astronomers think it has a strange shape Cartwheel Galaxy arose when a smaller galaxy passed through the center of another object. The collision created shock waves of gas that stimulated star formation. Chandra’s X-rays (in purple) show the hot gas that was blown 150,000 light-years away during the collision. Optical data from Hubble (red, green and blue) show where the collision may have caused star formation.
The Helix Nebula shows the future of our sun. In about 5 billion years, the the sun will run out of fuel burn and its outer layers peel off, leaving behind a colder core known as a white dwarf. Chandra shows the X-rays surrounding the white dwarf star (white) and you can view data in optical wavelengths from Hubble (orange and blue), ultraviolet from NASA’s Galaxy Evolution Explorer (cyan) and infrared from NASA Spitzer space telescope (green and red). The scene spans about four light years.
