Cometary globules are gas clouds with dusty heads and tails, often forming stars. The rupture in CG4’s head is unexplained, and the nearby galaxy is unrelated.

This Image of the Week showcases the stunning Milky Way gracefully arcing over the NSF Víctor M. Blanco 4-meter Telescope at the U.S. National Science Foundation Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF NOIRLab in Chile. CTIO is located at an altitude of 2200 meters (7200 feet) in the remote mountains of Chile. This location, high in the sky and far from city light pollution, allows telescopes like the Blanco Telescope to study the sky in breathtaking clarity. This image encapsulates the beauty of the cosmos and the sophisticated efforts undertaken by astronomers to unravel its mysteries. One such effort in which this telescope has played a major role is the Dark Energy Survey (DES). The survey examined the origin of the accelerating Universe to uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion. Over a six-year period, this telescope, armed with the Dark Energy Camera (DECam) fabricated by the U.S. Department of Energy, observed about two million distant galaxies and found several thousand supernovae. The results of this ambitious survey are being used to trace the history of cosmic expansion and study the nature of dark energy. This photo was taken as part of the NOIRLab 2022 Photo Expedition to all the NOIRLab sites. Petr Horálek, the photographer, is a NOIRLab Audiovisual Ambassador. Credit: CTIO/NOIRLab/NSF/AURA/P.

Another night of observing begins at the U.S. National Science Foundation Cerro Tololo International Observatory (CTIO) in the Chilean Andes, a Program of NSF NOIRLab, as the Moon sets below the horizon. The Moon appears massive and with a mysterious yellowish glow as it retreats behind the SMARTS–GSU 0.9-meter Telescope on the left, the SMARTS–GSU 1.5-meter Telescope in the center, and the Víctor M. Blanco 4-meter Telescope on the right.

Another night of observing begins at the U.S. National Science Foundation Cerro Tololo International Observatory (CTIO) in the Chilean Andes, a Program of NSF NOIRLab, as the Moon sets below the horizon. The Moon appears massive and with a mysterious yellowish glow as it retreats behind the SMARTS–GSU 0.9-meter Telescope on the left, the SMARTS–GSU 1.5-meter Telescope in the center, and the Víctor M. Blanco 4-meter Telescope on the right. Both the SMARTS-GSU telescopes are operated by the Georgia State University Research Foundation. Since ancient times the Moon has been recorded to appear larger when it rests near the horizon. Although some camera lens magic is at work in this Image of the Week, this is a real phenomenon that humans experience, known as the Moon illusion. It is entirely an optical illusion produced by the human brain! To prove the Moon is not actually bigger when it’s near the horizon, extend your thumb towards the Moon when it is high in the sky. The Moon will be around the size of your thumbnail. When the Moon sets or rises, making it appear larger, extend your thumb again towards it and you will find it is still the size of your nail. While there is no definitive explanation yet for why the brain interprets the Moon as larger when it is closer to the horizon, there are many factors that contribute to the illusion. For example, when the Moon is lower in the sky and peeking behind mountains or buildings the brain can perceive the Moon to be closer because of our familiarity with these structures.
