![]() ![]() Stapelfeldt (Jet Propulsion Laboratory), and ESO Processing Gladys Kober (NASA/Catholic University of America) Hubble observed a small part of IC2631 in a survey looking at the disks of newly-formed stars.Ĭredits: NASA, ESA, K. In 1912, American astronomer Vesto Slipher understood that light from a nearby star lights nebulae up rather than some intrinsic characteristic of the nebula itself. They even called galaxies nebulae.Īs time went on and telescopes and observations improved, they figured more things out. The word nebula means ‘cloud’ or ‘fog’ in Latin, so early astronomers called anything that appeared cloud-like a nebula. ![]() In the early days of astronomy, astronomers weren’t certain what they saw when they spotted a nebula. Blue light, because of its wavelength, is more easily reflected from grains of dust. ![]() Nebulae are often blue due to the way light scatters. The light from the star scatters through the cloud and reflects off of the gas, creating a beautiful display. There are many clouds of dust out there in space, but it’s the proximity of a star that brings a nebula to life. While searching for young stars and their circumstellar disks, Hubble captured a classic reflection nebula.Ī nebula starts with a cloud of interstellar dust. Nebulae are probably the most beautiful objects out there. But out in space, nature creates extraordinarily dazzling structures called nebulae that can span hundreds of light-years. Here on Earth, we enjoy rainbows, auroras, and sunsets and sunrises. The interplay of energy and matter creates beautiful sights. ![]()
