Number of distant galaxies fewer than thought

Number of distant galaxies fewer than thought

The number of distant galaxies could be 10 to 100 times fewer than earlier thought, astronomers estimate.

Massive black holes shut down star formation

All large galaxies have a massive black hole at their centre, each millions of times the mass of a single star.

Massive black holes found in distant galaxies

The find of supermassive black holes growing in surprisingly small galaxies suggest that central black holes form at an early stage in galaxy evolution.
