Pulsar is a type of neutron star. Because it will continuously emit electromagnetic pulse signals, it is named pulsar. This is an extremely dense special star body. The size of a piece of sugar cube has reached the mass of the whole human race.

At the "Science and Innovation Pioneer Forum·Future Power" in the 2022 Fudan University School of Management Science and Technology Innovation Week Series Forum, Wang Shen, a postdoctoral fellow at Chi Mingmin's research group and a doctorate at the National Observatory, told the story of how to find the "heartbeat of the universe".

pulsar is called the "cosmic heartbeat".

not only because its pulse signal is similar to the heartbeat, but also because it is closely related to the origin of life.

When people first discovered pulsars,

was surprised by its very regular pulse signals, and

even thought it was a signal from aliens.

The earliest burst record of pulsars was from the Tianguan Gu star recorded in Song Shi . It records a gorgeous supernova burst , and its product pulsar was later confirmed by the observations.

Where do we come from?

This is one of the basic problems of philosophy .

. The research of pulsars,

can help astronomers

better explore the mystery of 's origin of life

pulsars are the benchmark of space-time, like a lighthouse in the universe. We understand the pulsar's life cycle , and we also understand the life of supermassive stars in the late stages.

pulsar can not only answer the question "where to come from", but also answer the question "where to go".

pulsar is very important. Two forward-looking applications are called pulsar navigation and the other is pulsar timing.

The Age of Navigation Bohemian civilization has superb navigation technology, but lacks a bright star as navigation. Assuming that the Bohemian civilization developed optics very early and used optical telescopes to find some bright stars as their navigation targets, perhaps they will not be lost in the vast sea, and the development of civilization and the world pattern may be completely different. The research level of

pulsar,

also represents the heartbeat of a civilization.

pulsar can help detect extremely low-frequency gravitational waves, namely, Nanahtz gravitational waves. Therefore, the more samples are found in pulsars, the deeper we know ourselves.

China's original large scientific device "China Sky Eye" FAST is a hardware support for pulsars. After FAST is completed, can we discover more pulsars? Based on hardware support, an efficient software algorithm is also needed. The average outline diagram of some special pulsars discovered by

FAST The idealized pulsar search program is very complex, and the amount of data generated by " Tianyan " is very huge. It is time-consuming to rely on scientific researchers to handle it themselves. We are already considering adding artificial intelligence .

Perhaps many people think that

Astronomy is a distant science,

unpopular science,

But astronomy is not only an ancient science,

is also a science that keeps pace with the times.

Experimental science, theoretical science, computational science, and data science, these four scientific paradigms can be found in astronomical.

"For humans, exploration will continue to stop, sooner or later,

We will find our friends in the universe."

"We have responded to the universe, and

The universe will definitely respond to us."
