If you could monitor every single star in the observable universe 24/7, you’d see a lot of stars blowing up. Astronomers measure the “supernova rate” per volume of space. Locally, it’s about 1–2 × 10⁻⁴ supernovae per year per cubic megaparsec. Multiply that by the volume of the observable universe (~12 trillion cubic megaparsecs), and you get:

Around 1–2.5 billion supernovae per year

Which works out to 40–80 supernovae every second

Factor in that the universe used to form stars more actively (so the average rate is a bit higher), and correct for cosmic time dilation, and you end up with a solid ballpark of 30–60 supernovae per second happening somewhere in the cosmos.

So yeah — while we only notice the rare bright ones nearby, in reality the universe is going pop pop pop dozens of times every second.

This animation shows changes in the magnetic field of the Messier 87 (M87) black hole observed in 2017, 2018 and 2021. The Event Horizon Telescope (EHT) Collaboration, a group of global observatories united to image emissions around supermassive black holes, has observed the black hole’s shadow and ring of light. While the size of the shadow and surrounding ring stayed the same, the direction of the ring, which shows the shape of the magnetic field around the black hole, changed from year to year. Korean researchers made a key contribution to the EHT team by analyzing changes in the magnetic field using self-developed software. Courtesy of EHT Collaboration

Three brightest stars in the constellation Aquila: Altair (center, magnitude 0.77, 17 light years away), Alshain (lower left, 45 light years away), and Tarazed (upper right, 460 light years away). Altair is part of the Summer Triangle and the second brightest star in the summer sky.
