Astronomers think that every large galaxy in the universe has a supermassive black hole at its center.

A new study found that 35% of these black holes are heavily obscured, meaning clouds of gas and dust are so thick they block even low-energy X-ray light.

Scientists think the true split should be closer to 50/50 based on models of how galaxies grow.

In addition, black holes influence the galaxies they live, mostly by impacting how they live.

If we didn't have a supermassive black hole in our Milky Way galaxy, there might be many more stars in the sky.

That's just one example of how black holes can influence a galaxy's evolution, says Poshak Gandhi , a co-author of the new study.
