Scientists are focused on listening for signals at the center of the Milky Way. There are stars and dense exoplanets capable of supporting life.
Can intelligent aliens hide in the center?
We are always on the lookout for extraterrestrial life by listening radio pulse from the center of our galaxy. Narrow frequency pulses are naturally emitted by the star called pulsarbut these pulses are also used by humans in technologies such as radar.

These pulses stand out against the radio noise of space, making them an effective means of communicating over great distances, and an attractive target for our attention when searching for extraterrestrial civilizations on the planet.
In a new study just published on May 30, researchers outline a strategy for hunting aliens. Doctoral student Akshay Suresh from Cornell University, New York, USA, is the leader of the research team.
His team developed software that detects these repetitive frequency patterns and retested them on known pulsars to confirm that the software can pick up chive frequencies. These frequency bands are very small, only 1/10 the width of the frequencies used by FM radio stations.
The team then used this method to search for data from the Green Bank Telescope in West Virginia.
Until now, radio seti (from the TETI Institute – a non-profit organization in the United States specializing in the search for extraterrestrial life) mainly looking for continuously transmitted signals.
This new study sheds light on the remarkable energy efficiency of a pulse train as a means of interstellar communication. It is also the first complete and in-depth study of the signals emitted from the galactic center.
Scientists are focused on listening for signals in this central region because it is densely packed with stars and exoplanets that could harbor life.
Additionally, if the galactic core wants to reach the rest of the galaxy, they can send a sweeping signal through a series of planets through their vantage point at the galactic center.
Ϲresearchers reported using narrow bandwidth and repetitive broadcast patterns will be the primary method used by extraterrestrials to show their existence, as the combination of these two factors is unlikely to occur due to coincidence.
This search method uses an algorithm that can sift through 1.5 million telescope data samples in 30 minutes. Although the researchers found no telltale signs during the first search, they say the speed of the algorithm will help improve search efficiency later on.
This research project has collected an enormous amount of data and the technique the research team has developed offers a new method in hopes ofg “the needle that was in the bag for a long time also came out” and we will find amazing evidence of advanced extraterrestrial life forms.
