A Two Percent MoonA young crescent moon can be hard to see. That’s because when the Moon shows it’s crescent phase (young or old) it can never be far from the Sun in planet Earth’s sky. And even though the sky is still bright, a slender sunlit lunar crescent is cleary visible in this early evening skyscape. The telephoto snapshot was captured on…Read More

A Dark Veil in OphiuchusThe diffuse hydrogen-alpha glow of emission region Sh2-27 fills this cosmic scene. The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil of wispy interstellar dust clouds draped across the foreground is chiefly identified as LDN 234 and LDN 204 from…Read More

Galaxies, Stars, and DustThis well-composed telescopic field of view covers over a Full Moon on the sky toward the high-flying constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy. The faint but pervasive…Read More

WISPIT 2b: Exoplanet Carves Gap in Birth DiskThat yellow spot — what is it? It’s a young planet outside our Solar System. The featured image from the Very Large Telescope in Chile surprisingly captures a distant scene much like our own Solar System’s birth, some 4.5 billion years ago. Although we can’t look into the past and see Earth’s…Read More

The Meteor and the Star ClusterSometimes even the sky surprises you. To see more stars and faint nebulosity in the Pleiades star cluster (M45), long exposures are made. Many times, less interesting items appear on the exposures that were not intended — but later edited out. These include stuck pixels, cosmic ray hits, frames with bright clouds…Read More
