Astronomers discover a supermassive black hole that traps 6 galaxies

The most recent supermassive black hole we have detected is located at the center of the SDSS J103027.09 052455.0 quasar. It has a mass of one billion times the mass of the Sun and such a powerful gravity that it traps as many as 6 galaxies closest to it. It should be emphasized that its gravitational tentacles extend over 300 times the diameter of the Milky Way. Interestingly, this black hole is a very old object that was formed only less than a billion years after the Big Bang.

The first effective artificial sun in the US is to be ready in 5 years

Scientists from the Massachusetts Institute of Technology and Commonwealth Fusion Systems said they are in the process of building an experimental artificial sun called SPARC. Their reactor is to be the first in the world to achieve a positive energy balance, which means that it will produce more energy during operation than it will use to keep the plasma heated.

Here is the world's first 3D-printed fiberglass boat

Moi Composites presented at the Genoa Boat Show 2020 the world's first fiberglass boat, which was created with the participation of 3D printing. Mambo, because we are talking about it, is equipped with a powerful engine, it is 6.5 meters long and 2.5 meters wide. Do you admit that it looks great? This is due to its unusual inverted triangle shape, which was based on the famous Arcidiavolo construction by Sonny Levi. It would not have been possible to obtain it using the traditional techniques of building this type of boat.

Spectacular view of Saturn's rings from the perspective of Cassini spacecraft

Kevin Gill, an expert in multimedia data analysis at NASA, has posted another cosmic footage on his YouTube channel. This time we can see all the beauty and mystery of the rings of the second largest planet of the solar system. Although the probe's mission is now over, scientists are still analyzing the data and gaining valuable insight into the history of the rings, their evolution, and the impact on Saturn, its moons and the solar system.

Hackers from the Belarusian opposition began to disclose the exact data of the services

Hackers from the Belarusian opposition began to disclose the exact data of the services

The situation in Belarus has been very tense since the last presidential election - the country is torn by successive waves of protests from citizens who are already fed up with Alyaksandr Lukashenka's regime and subsequent brutal responses from local services. After one of the last ones, the blogger NEXTA announced via the Telegram messenger that he was in possession of the employees of the Belarusian services and that if the situation with the interventions was repeated, he would simply make them public. Unfortunately, this is what happened ... unfortunately, because on Sunday there were more detentions of citizens, this time during the Women's March in Minsk.

Listening to classical music significantly reduces the number of epilepsy episodes

Listening to classical music significantly reduces the number of epilepsy episodes

It all started in 1993, when the psychologist Francis Rauscher conducted a small experiment on a group of 36 students, namely checking their visual-spatial intelligence under 3 different circumstances. Each test was performed immediately after 10 minutes of silence, 10 minutes of vocal relaxation, and 10 minutes of listening to two Mozart pieces. It quickly turned out that the latter variant resulted in an average of 10 points higher results - since then we have been hearing about the so-called the Mozart effect, i.e. a slight improvement in spatial abilities and general intelligence caused by listening to works of baroque and classical music, especially Wolfgang Amadeus Mozart.
