9 lip 2024 · For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
Newly forming star stretched a light-year long. Hot, bright stars generate harsh stellar winds that are blast ultraviolet radiation toward a protostar, sculpting it into the...
12 lip 2022 · Webb’s exploration of exoplanets is off to an incredible start with this image showing the presence of atmospheric water vapor on WASP-96 b, a hot, gassy planet some 1,150 light-years from...
Rising from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33, which resides roughly 1,300 light-years away. The NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date of one of the most distinctive objects in our skies, the Horsehead Nebula.
28 maj 2020 · The light year (ly) is a unit of length that is the distance light travels in a vacuum in one Earth year. One light year is approximately 9.46 trillion kilometers (9.46 x 10 12 km) or 5.88 trillion miles (5.88 x 10 12 mi).
22 gru 2021 · A light-year is a measure of astronomical distance: Light travels through a vacuum at precisely 983,571,056 feet (299,792,458 meters) per second, making a light-year approximately 6 trillion...
12 lip 2022 · NASA released high-resolution color images from its James Webb Space Telescope. Scientists say the pictures will change the way people see space. Webb began taking its first images a few weeks ago....
