An unknown source in space has been sending long radio signals to Earth for at least 35 years, scientists say in a paper published Wednesday in the prestigious science journal. Nature. The characteristics of these signals do not correspond to any of the explanatory models developed by scientists to date, specify, relate the independent.
particularly long signals
This source was only recently identified, but archival analyzes have shown that signals of the same type ranging up to 21 minutes with variable intensity have been regularly captured since at least 1988.
They could be likened to signals emanating from pulsars or “fast radio bursts,” but these sources typically emit radio waves lasting from a few milliseconds to several seconds.
Pulsars are neutron stars that rotate on their axis at very high speed, emitting radio waves through this movement. Radio “bursts” correspond to anomalies in radio frequency readings from space. In both cases, broadcasts lasting several minutes were never recorded.
The trail of a white dwarf
If the emitting object is a pulsar, then it would go beyond the models accepted by the scientific community up to now, even behaving in a way that experts until now believed impossible.
Astrophysicists working with these data also evoke the hypothesis of a “white dwarf” or “magnetar” type star, a star whose magnetic field is particularly strong. The emissions that these types of objects usually send, however, are different from the recently identified signals.
