Summary
In this episode of Astronomy Daily, Anna and Avery cover six space and astronomy stories for Saturday, April 18, 2026. Comet MAPS has met its end at the Sun — the pair reflect on what happened and what comes next. Artemis III's SLS rocket stage rolls out of New Orleans on Monday. JWST and ALMA have revealed a stunning monster spiral galaxy hiding behind cosmic dust 11.5 billion years ago. An exoplanet system is changing its orbital architecture in real time. Four planets are gathering in a pre-dawn planet parade visible tonight. And 33,000 hydrogen halos have been found that solve a decades-old mystery about the early universe's fuel supply. Story 1: Comet MAPS — Death of a Sungrazer Comet C/2026 A1 (MAPS), a Kreutz sungrazer discovered on January 13, 2026 by French amateur astronomers at the AMACS1 Observatory in Chile, disintegrated during its close solar approach on April 4. The nucleus — estimated at approximately 400 metres in diameter based on JWST observations — could not survive passage just 160,000 km above the solar surface. A brief dust tail was visible in coronagraph images from SOHO and GOES-19, but the debris cloud has since dispersed. Attention now shifts to Comet C/2025 R3 (PanSTARRS) as the next comet of interest. MAPS was the furthest-discovered Kreutz sungrazer in history, spotted 81 days before perihelion.
