This is a recently released Hubble's image of the COSMOS field - part of the sky used by astronomers to study the distant universe. It contains pictures of many galaxies, some of them with redshift over 2. That means their light has been stretched by the expansion of the universe into the infrared part of the electromagnetic spectrum.
Astronomers looked at the nearby red dwarfs to analyze radio waves coming from them. In most cases they caught waves from magnetically active stars, which was no surprise, however 4 of the stars generating radio waves were not magnetic. In their newly published study the scientists propose the signals coming from yet unseen exoplanets. If confirmed, radio signals could become a new way for detecting exoplanets.
In several months Vera Rubin observatory in Chile will be finished and receive its first light. Unique technology of this telescope might allow astronomers identify special type of objects - interstellar asteroids or comets.
