Mysterious signals from a 10-kilometer-wide object

For years, powerful radio signals from space have given rise to speculation about extraterrestrial life. Now the source of the signals has been determined: an object three billion light-years from Earth.

For a number of years, telescopes on Earth have been receiving powerful radio signals that vary in type and length but come from the same place in the universe.

The signals have been baptized FRB 121102 and have led to speculation as to whether intelligent extraterrestrial life is trying to contact us.

Recently researchers from the University of Amsterdam, Leiden University, ASTRON and JIVE have determined the home address of the signals in the universe.

According to the researchers, they are probably from a neutron star with a diameter of 10 kilometers in a dwarf galaxy three billion light years from Earth.

Neutron stars attract their environment

Neutron stars are relatively small objects that carry enormous powers.

They arise when big stars explode like supernova.

After the explosion, the core of the star collapses, resulting in a small but heavy neutron star.

Due to its enormous mass, the neutron star has an extremely high gravity that pulls on the environment.

Neutron star is in an extreme environment

The researchers who discovered the neutron star with a diameter of 10 kilometers write that the object is in an extremely ionized environment and is surrounded by a strong magnetic field.

Living as we know it cannot live in such an environment. Yet the researchers do not entirely reject the hypothesis that the signals come from extraterrestrial life.

However, they still do not know exactly how the signals originate.

Now that the origin of the signals is known, astronomers can better investigate the phenomenon in the future.

New study determines the age of 0

Since 1902, an old manuscript has been in the library of the University of Oxford. It consists of 70 birch bark pages. But that was not what the researchers noticed most when the manuscript was found in 1881 in the village of Bakhshali, now in Pakistan. Much more interesting were the hundreds of zeros on the yellowed bark.

Anatoli was shot in the head by a particle accelerator

When Anatoli Boegorski now looks in the mirror, he sees two different people. One side of his face bears the signs of the 75 years he has lived, but the other side is frozen in time and does not seem to have aged a day since July 13, 1978. On this fateful summer day in 1978, the Russian scientist was the victim of a unique accident in world history.

Who invented our time schedule?

Thousands of years have been planed for our time structure. Around 4,000 years ago, the Babylonians in present-day Iraq introduced a calendar that was divided into years, months, and weeks based on the movements of the great celestial bodies. A year was the time when the earth revolved around the sun once, and a month was the time it took the moon to revolve around the earth.

The book has had many appearances. Already around 3000 BC. wrote the Sumerians with cuneiform script on clay tablets; the Egyptians at the same time wrote hieroglyphs on pressed papyrus strips. Only around the 5th century AD. the book appeared in the physical form that we still know today - so as a number of merged pages, held together by a cover.
