The core of our galaxy, seen in infrared light by the Spitzer Space Telescope. Blue light is from stars, green light is from polycyclic carbon molecules, yellow and red light is from the thermal glow of warm dust. This image spans approximately 1000 light years by 1600 light years. The galactic core is 26000 light years away.
Voyager 1 has entered interstellar space. The NASA spacecraft, which rose from Earth on a September morning 36 years ago, has traveled farther than anyone, or anything, in history. Now Voyager 1 is in the space between the stars
Humility: Andromeda’s actual size, not accounting for the fact it is 2.5 BILLION LIGHT YEARS away, compared with the moon's 238,000 MILES away. It contains a Trillion stars, while our galaxy contains at most a half a billion stars... And some on earth delude themselves that they are the center of Everything.
August 14, 2007: The Hubble Space Telescope captures this rare view of the ring system of the planet Uranus, tilted edge-on to Earth. The rings can only be seen edge-on from Earth every 42 years as Uranus follows a 84-year orbit about the sun. The last time the rings were tilted edge-on to Earth (1965), astronomers didn't know they existed. The rings were discovered in 1977. Credit: NASA/ESA/STScI
The Orion Nebula, 1,340 light-years from Earth, is actively making new stars. The IRAC camera peered through the dust and found a long filament of thousands of stars in their early stages. Some of these stars may host planets.
