Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’re going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.<\/p>\n
Good morning. It\u2019s January 25, and today\u2019s image is nothing short of amazing and inspirational.<\/p>\n
Courtesy of the James Webb Space Telescope, this image features a nebula, N79, in the Large Magellanic Cloud, a nearby small galaxy. (Can we call galaxies small?) This is a massive, super-active star-forming region that spans more than 1,600 light-years. So what\u2019s with that bright spot in the middle of the image? It\u2019s a bright young star.<\/p>\n
\u201cThe distinct \u2018starburst\u2019 pattern surrounding this bright object is a series of diffraction spikes,\u201d explains the European Space Agency. \u201cAll telescopes which use a mirror to collect light, as Webb does, have this form of artifact which arises from the design of the telescope. In Webb\u2019s case, the six largest starburst spikes appear because of the hexagonal symmetry of Webb\u2019s 18 primary mirror segments. Patterns like these are only noticeable around very bright, compact objects, where all the light comes from the same place. Most galaxies, even though they appear very small to our eyes, are darker and more spread out than a single star, and therefore do not show this pattern.\u201d<\/p>\n
Webb is looking at this active region to help astronomers understand what star-forming areas may have looked like in the early Universe.<\/p>\n
