One week to capture 110 Messier Objects

From March 10-16, 2021, astronomers and space-lovers worldwide are invited to participate in a record-setting world’s largest*Messier marathon:A race to observe all 110 Messier objects in one evening . For space-lovers who can’t spare an over-night,Unistellar has developed numerous mini marathons which can be completed in as little as one hour of observation time.

MOUNTAIN VIEW AND MARSEILLE – February 25, 2021 – Astronomers across North America, Europe and Japan have joined forces for a friendly competition to observe iconic deep-sky objects—all in hopes of getting stargazers curious about astronomy in March.

Messier Marathon Week, hosted by Unistellar and now in its second year, challenges stargazers to observe as many Messier objects as possible in one night. Events take place March 10 – 16, 2021, the only time of year that all Messier objects are visible in one night. If enough stargazers participate, Unistellar hopes to set a world record for the largest Messier Marathon event.

Some of the world’s leading astronomy institutions have signed up for the Unistellar Marathon, giving stargazers across multiple contents and languages access to diverse perspectives on space. Organizations including the SETI Institute plan to participate, either by attempting a Messier marathon or by sharing their best Messier observations.
