Black holes are one of the most powerful forces in the universe, swallowing up everything in their wake. A small black hole is considered to have a mass at least six times that of the Sun - but even one just 1mm in size could still wreak havoc, an expert has said. Hypothetically, if one of that size were to form on Earth, its immense gravitational pull could still tear the planet apart.
Hossam Aly, Ph.D Astrophysics, University of Leicester, said a 1mm black hole would still have a mass of 10 percent that of Earth.

NASA news: Supermassive blackhole creating stars at a 'furious rate' found | Science | News |
Galaxy clusters typically consist of thousands of galaxies held together by strong gravitational forces, with the most powerful black holes ever discovered lying at their centres. In the usual galaxy clusters observed the black holes at their centres were so strong they actually prevented the creation of stars, but the “phoenix cluster” just discovered boasts some key differences that have shocked scientists.
If stronger, the black hole at its centre would prevent this cooling and therefore prevent any creation of stars, but these unique circumstances may provide scientists with some answers to some of the greatest questions ever put to them.

The galactic cluster sits approximately 5.8 billion light-years from Earth and is one of the fist clusters where young stars are being born close to the core.
Supermassive black holes typically stifle the rate at which stars are born but the Phoenix Cluster stands out from similar galactic bodies.
NASA said: “For decades, astronomers have looked for galaxy clusters containing rich nurseries of stars in their central galaxies.
Scientist Warns Of How 1-Millimeter Black Hole Could Destroy Earth
An astrophysicist described what would happen if a black hole that's only 1 millimeter wide suddenly appears on Earth. According to the scientist, the black hole's gravitational pull would still completely tear Earth apart despite its tiny size.
Black holes are some of the most powerful forces in space. Due to the immense gravitational force they exert, they are oftentimes regarded as one of the most dangerous cosmic threats that can destroy Earth in an instant.

Black hole shock: Supermassive monsters are ... galaxies to birth new stars
It now appears black holes actually encourage rather than annihilate stars inside a galaxy cluster. Supermassive black holes typically pump out energy via jets, keeping nearby areas too warm to condense and form stars.
Scientists have now discovered a cluster of galaxies, called the Phoenix cluster, where stars form at a furious rate because of a supermassive black hole’s influence.

Where our Milky Way forms one star per year on average, newborn stars are created in this cool gas at a rate of about 500 solar masses per year in the Phoenix cluster.
