Interstellar distances can also be measured in parsecs. Solar system are usually measured in Astronomical Units (AU). The physical distance from Earth to the astronomical object. One of 88 recognized regions of the celestial sphere in which the object appears.

Credits ImageĪ name or catalog number that astronomers use to identify an astronomical object. NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center. ![]() Spiral galaxies like this are typically dominated by young stars that appear blueish in these wavelengths. Scientists say this particular galaxy, previously unexplored in detail, may be about a billion light-years away. Towards the bottom left of this image, a barred spiral galaxy comes into focus. However, Neptune appears relatively small in a wide-field view of the vast universe. In most portraits, the outer planets of our solar system reflect this otherworldly size. If Earth were the size of a nickel, Neptune would be as big as a basketball. Neptune, when compared to Earth, is a big planet. ![]() In this image by Webb’s Near-Infrared Camera (NIRCam), a smattering of hundreds of background galaxies, varying in size and shape, appear alongside the Neptune system. ![]()
