The source of the March fireballs may finally have been identified, with scientists saying Earth is currently passing through a newly discovered trail of debris left behind by an asteroid that was broken apart near the Sun. The finding helps explain why so many bright meteors were seen around the world in recent weeks.
Researchers led by NASA scientist Patrick M. Shober analysed millions of meteor observations from all-sky camera networks in Canada, Japan, Europe and California. They found a distinct cluster of 282 meteors that appears to belong to a previously unknown meteor shower.
The newly identified shower has been provisionally named M2026-A1. Researchers say it is active every year from about March 16 to April 7, and that Earth is now moving through debris shed by a crumbling asteroid. That means the fireballs seen in March may not have been random at all. Instead, they were likely part of a larger and newly recognised debris stream intersecting Earth’s orbit.

The Sun is constantly trying to sandblast our atmosphere into deep space. It launches a million-ton stream of plasma at 1.6 million kilometers per hour. When this supersonic wind hits Earth’s magnetic field, it creates a "Bow Shock."

— The Scientific Lens (@LensScientific) April 13, 2026Most well-known meteor showers come from comets, which release dust and ice as they warm near the Sun. However, M2026-A1 is unusual because it appears to come from a dry asteroid behaving like a comet. Scientists describe this kind of object as a “rock-comet.” In this case, intense solar heat may have cracked the asteroid’s surface, released trapped gases and caused it to crumble into a dusty trail.
Scientists Analysed Millions of Meteor Sightings
The discovery came after researchers examined data from global sky-monitoring networks and isolated 282 meteors that stood apart from known showers. That cluster helped them identify what they believe is a newly formed meteor stream. The parent asteroid has not yet been located. Even so, the debris it left behind appears to be enough to produce visible fireballs as Earth crosses its path.

— Michael Bradbury (@MrMBB333) April 15, 2026This finding is notable because it shows scientists may be watching an asteroid actively break apart in near real time. Instead of a long-known comet trail, this appears to be a fresh debris stream created by solar heating and disruption. Researchers describe the process as a hidden asteroid being “baked to bits” by the Sun. That makes the discovery both scientifically unusual and visually dramatic for skywatchers.
Stargazers may continue to see more meteors as Earth finishes crossing the denser part of the debris field. It also notes that the shower is expected to return annually around the same dates, though its intensity may change over time.
