A few months ago scientists spotted a red star in deep space from the Arecibo Observatory. But, astronomers are keeping an eye on the star after it emits strange signals.

As part of the scientific campaign, scientists observed a list of stars in space. The observations were conducted from April to May using the Arecibo Observatory situated in Puerto Rico. During this observation scientists acquired information about the magnetic environment and radiation from some stars, the PHL reported. These stars include a strange red star named Ross 128, and scientists observed it on May 12.

Two weeks after the said observations the scientists realized strange signals from the Ross 128 or the red star. They noticed these peculiar signals in a 10- minute data. The signals reveal that the star is pulsing in deep space, though the key reason behind this strange signal is not yet known.

So far scientists could not explore the origin of these strange signals from the red star, but three probable explanations have surfaced. The first explanation indicates that the reason behind the signals from Ross 128 could be the solar flares. The second one says that the emissions could come out from another object. The last or the third explanation hints that the emissions could be the aftermath of a burst from one high orbit satellite.

The important fact is each explanation has own problems. Famous planetary astrobiologist Abel Mendez says through a Twitter message that it is the first time that such strange signals surfaced, Mashable reported. The red star might have the flaring period, but there is no consistency between its frequency and the past similar events. Abel Mendez is the Director of the Planetary Habitability Laboratory and the NASA MIRS Fellow at the University of Puerto Rico. 

Abel Mendez has also hinted the probability of aliens, but only as a last option. He says that the aliens hypothesis must remain at the bottom of other explanations. The red star or the Ross 128 is like other known stars to the astronomers. Now gathering more information about this star will help scientists to know about the vast population of the stars not so distant from the earth.

Abel Mendez and the team once again observed Ross 128 on July 16. This recent observation might help them to clarify the actual nature of the red star's radio emissions. In a word, they could explore whether deep space is the real source of the signal or it is terrestrial. Currently, the scientists are submitting results of their observations about the signals of the red star, and they will probably announce their observations this week.
