First Signs of the Galaxy with a Heartbeat

"galaxy Messier 87 and its pulses"

Galaxy Messier 87 surprised NASA astronomers with ts heart-beating rhythm.

After a minute research in space, scientists have observed the first signs of the galaxy with a heartbeat. The discovery was made possible due to a series of pulses coming from the stars of the galaxy.

The study was included in the recent number of the journal of Nature. According to scientists’ explanations, it was initially thought that the newly discovered galaxy was dying. It was the pulses coming from the galaxy that gave researchers these impressions.

Pulses are usually specific for old galaxies, which could be dying in a very short period of time. The next step that researchers have made was to determine the exact age of the galaxy and its stars, based on its pulses.

The Messier 87 galaxy is 10 billion years old, according to scientists’ predicaments. This estimation is in keeping with previous research indicating that the galaxy is ancient.

However, the discovery of the galaxy and its age are not the only aspects that thrill scientists. They have been particularly impressed by the efficiency of the new study method. Charlie Conroy, the lead author of the study and assistant professor at the Harvard University has explained that the new pulse-based investigation is a new tool that scientists can use in their research.

Estimating the age of a galaxy can only be done with the help of very few methods. This makes the finding of the new tool all the more important, as Conroy has stated. Thanks to the new pulse-based method, it has become much easier to set the age of ancient galaxies and time is really important in their case.

Conroy has further stated that the M87 galaxy is, indeed, 10 billion years old. This means the galaxy is a fossil relic, which appeared a long time ago in the universe. What’s more interesting about it, is that the galaxy appears to have its own heartbeat.

Its average pulse was set at one beat in 270 days, which means there is a lot of change going on inside the galaxy’s structure. However, this rhythm is not something new for researchers; galaxies are not just beacons in the sky. They have pulsating stars, but the distance makes them appear as continuous lights.
