🌌 A STAR IS EXPLODING 45 MILLION LIGHT-YEARS AWAY — AND YOU CAN SEE IT
Something extraordinary is happening in our night sky.
Astronomers have discovered SN 2026aaiv, a Type Ia supernova exploding in the spiral galaxy NGC 7331, about 45 million light-years away in the constellation Pegasus. And remarkably, it has been getting brighter since its discovery on September 1.
But there is something even more incredible to understand:
This explosion happened 45 million years ago.
The light we are seeing tonight began its journey across the universe when Earth was in the early Eocene. The dinosaurs had already been gone for roughly 20 million years, while mammals were beginning to diversify into many of the forms that would eventually shape the modern world.
That ancient light has been traveling through space for 45 million years — and only now is it reaching our telescopes.
And you can actually try to find it.
🔭 Where should you look?
SN 2026aaiv is inside NGC 7331, also known as Caldwell 30, in Pegasus.
After dark, look toward the eastern sky and find the famous Great Square of Pegasus — four bright stars forming a huge diamond. From the northwestern corner, marked by the star Scheat, look just above the square toward the fainter star Matar. NGC 7331 lies nearby.
The supernova is located at:
RA 22h 37m 05.6s
Dec +34° 24′ 35″
You won't see it with your naked eye. NGC 7331 itself requires binoculars or a telescope, while the supernova is considerably more challenging. Observers have already reported seeing it with a 14-inch telescope, and astrophotographers using relatively modest smart telescopes have captured it as well.
And here's one more astonishing coincidence:
NGC 7331 produced another Type Ia supernova just last year.
Two stellar explosions in the same galaxy within roughly a year is an extraordinarily rare occurrence.
So when you look toward Pegasus tonight, you're not simply looking at a distant galaxy.
You're looking at ancient light that has crossed 45 million years of space and time to reach you.
✨ Somewhere out there, a star died long ago.
And tonight, its final light is finally arriving at Earth.
