**official astrophysics thread** A large supernova is currently visible in the night sky. The closest to earth that astrophysicists have observed in 50yrs at a mere 21million light years away. Situated near Ursa Major 'the Great Bear' aka 'the Plough' or 'the Big Dipper' or as many people know it 'the Saucepan', it can be found by following the natural line of the handle to the second star and extending that line outwards approx x2... |

'This Hubble Space Telescope image of SN 1987A shows a fished-shaped central blob of supernova debris that has begun to brighten. This brightening, due to illumination by X-rays from the surrounding ring of pre-supernova material, marks the shift from a supernova to supernova remnant. The closest supernova explosion seen in almost 400 years, SN 1987A is located in the Large Magellanic Cloud.'

Should appear as a distinct white patch in the sky and be visible for the next 10 days or so. It appears to be affecting my signal too. I want a nightly tv show with Kate Humble, Dr Brian c0x and Sir Patrick Moore,

Brian May could do the theme tune.

It'd take four billion, seven hundred and twenty five million years to walk to that star.

Could u clarify one thing? Surely its visible now and has been for sometime. They can't predict a supernova appearing in a few days or weeks or months in advance. They appear when the light reaches us. There is a bright 'star' in the region u describe but i assumed it was jupiter or saturn as i've not noticed a star there before.

I wondered that myself driver, dunno. It looks like a milky patch, so that probably is a passing planet or maybe the ISS,

Most likely that region of space has just come into view and will disappear back under the horizon at night in 10 days or so!
