Comet SWAN puts on a must-see sky show as it becomes visible with binoculars without telescope

A new comet is visible in sky, C/2025 F2, and can be discovered low in the east just before the dawn twilight. Reports said Minor Planet Center officially designated comet SWAN25F as C/2025 F2 on April 8. SWAN is an instrument particularly designed to study the Sun by mapping variations in the solar wind captured images in late March, in which Australian amateur astronomer Michael Mattiazzo spotted the comet. Numerous comet observers poring over images captured by the SWAN camera onboard NASA’s SOHO solar observatory independently spotted what they considered might be a comet moving through them. However, long-exposure images captured through telescopes reveal a slender, whip-like tail extending at least a degree across the sky, besides the comet’s vivid green hue.
