Astronomers have picked up a radio signal coming from a planet outside our solar system, according to De Telegraaf. The Dutch newspaper reported the detection on Sunday, describing it as the first time such a signal has been traced to an exoplanet.
De Telegraaf did not name the planet or the team behind the work in the material available. The report gives no details on the strength of the signal, the distance involved, or the method used to identify its source.
The claim matters because radio observations have long been used to study objects within our own solar system, including planets with strong magnetic fields. Extending that approach to a world orbiting another star would give researchers a second channel for examining an exoplanet, alongside the light-based techniques that currently dominate the field. Most exoplanet knowledge today comes from measuring how a planet dims or shifts the light of its host star, which reveals size, orbit and in some cases atmosphere, but not much about what happens around the planet itself.
Any single detection of this kind would need to be checked before it is treated as settled. Confirming that a signal originates from a planet rather than from its star, from background sources, or from instruments on or near Earth is a standard part of the process.
What to watch next: whether the team behind the finding releases the data and the identity of the planet, and whether other observatories can repeat the detection independently.
