Astronomers are buzzing with excitement over Comet C/2026 A1 (MAPS), a newly discovered sungrazing comet that has the potential to become one of the most spectacular celestial events of 2026. Discovered on January 13, 2026, by a team of four astronomers — Alain Maury, Georges Attard, Daniel Parrott, and Florian Signoret — using robotic telescopes in Chile’s Atacama Desert, this comet belongs to the famous Kreutz sungrazer family.
What makes C/2026 A1 (MAPS) extraordinary is its planned perihelion on April 4–5, 2026, when it will skim just 160,000 kilometers above the Sun’s surface, diving deep into the solar corona. At such a dangerously close distance, the comet faces two possible fates: either it dramatically brightens to outshine Venus, or it shatters under the Sun’s intense heat and gravity.
Early observations show that MAPS is unusually active for a comet discovered this far from the Sun — at about 2 AU (astronomical units). Scientists compare its potential to Comet C/2011 W3 (Lovejoy), which survived a similar close encounter in 2011 and became as bright as Venus. Optimistic projections suggest MAPS could even become visible in daylight.
The comet belongs to a group believed to be fragments of a parent body over 100 km wide that broke apart centuries ago. Its orbital period is estimated at around 850 years, meaning this is a once-in-a-lifetime sky event.
Observers in the Southern Hemisphere will have the best viewing opportunities in mid-to-late April 2026, especially during morning twilight. Solar observatories like SOHO and STEREO will track the comet’s fiery passage regardless of whether it survives.
Skywatchers are advised to follow updates from NASA and ESA as April approaches, as this could be the greatest comet of the decade.
