By combining the visible and infrared capabilities of NASA’s Spitzer and NASA/ESA Hubble space telescopes, a team of specialists at NASA’s Universe of Learning program has created a spectacular, three-dimensional, fly-through movie of the famous Orion Nebula, a diffuse nebula in the constellation Orion.
A star-forming galaxy 12.8 billion light-years away offers insight into the early days of our universe after the Big Bang roughly 13.7 billion years ago.
New Hubble images have now revealed the object is actually two asteroids.
The NASA/ESA Hubble Space Telescope has produced a remarkable new image of a pair of interacting galaxies known as NGC 5765.
Strange beams of plasma that have been observed that seem to defy the laws of physics by moving faster than the speed of light.
