Warsaw astronomers discover Milky Way's longest-period classical Cepheid

Astronomers from the Astronomical Observatory at the University of Warsaw have discovered a massive variable star, i.e. a classical Cepheid, with the longest pulsation period in our galaxy. According to researchers, it is not only the brightest, but also probably the youngest known classical Cepheid in the Milky Way. It is 22 million years old.

    Planets form everywhere and are very common, says Toruń astronomer

    ‘Planets form wherever possible and they are very common. Although astronomers already know over 5,000 extrasolar planets, called exoplanets for short - we are still surprised by their diversity and the differences between most planetary systems and our parent system, the Solar System,’ says astronomer Dr. Grzegorz Nowak from the Nicolaus Copernicus University in Toruń.
