    Astronomy

    A son of mine who spends most of his time in the clouds anywayhas expressed an interest in astronomy. Anyone out there know anything about telescopes for beginners? No, the Hubble is out and Patrick Moore is uncontactable so if any of you budding or experienced stargazers can help, I'd appreciate same.

    Not exactly astronomy but just in case someone’s interested. Might be worth a look if it’s a clear morning.

    Earth is a pretty small planet, in relative terms.
    Think of how large Jupiter and Saturn are in comparison and you get an idea for how small our home is.
    Now, Nasa's Spitzer Space Telescope has found a new planet, called OGLE-2016-BLG-1190Lb, which is 13 times the mass of Jupiter

    It's so large that astronomers are contemplating it may not be a planet.
    Researchers at a range of universities around the world have reported the discovery, which they say: raises the question of whether such objects are really 'planets'(formed within the disks of their hosts) or 'failed stars' (low mass objects formed by gas fragmentation).
    They continue: It is precisely measured to be right at the edge of the brown dwarf.

    This is somewhere between 13 and 14 Jupiter masses. OGLE-2016-BLG-1190Lb has about 13.4 Jupiter masses.

    Since the existence of the brown dwarf desert is the signature of different formation mechanisms for stars and planets, the extremely close proximity of OGLE-2016-BLG-1190Lb to this desert raises the question of whether it is truly a 'planet' (by formation mechanism) and therefore reacts back upon its role tracing the Galactic distribution of planets, just mentioned above.
    The planet is around 22,000 light years away - but further observations are encouraged to help shape our perceptions of planets, dwarf stars, and gaseous masses.

    I recorded it and hope to watch it soon.

    Yes watching it now. As I said elsewhere, it's great to see Birr reclaiming its astronomical heritage. It's once again at the center of the Universe.

    Not directly. Can cause CMEs which can come in the direction of the Earth and produce the fantastic Northern and Southern lights.
