    If its gravitational waves you seek come round my place when I have upset my wife, puts warping of space-time and colliding black holes back in their box!

    Sentry Risk Table
    The following table lists potential future Earth impact events that the JPL Sentry System has detected based on currently available observations. Click on the object designation to go to a page with full details on that object.
    Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalog for possibilities of future impact with Earth over the next 100 years. Whenever a potential impact is detected it will be analyzed and the results immediately published here, except in unusual cases where an IAU Technical Review is underway.
    It is normal that, as additional observations become available, objects will disappear from this table whenever there are no longer any potential impact detections. For this reason we maintain a list of removed objects with the date of removal.

    A star is born. Only a prediction, it is has not happened yet.

    "A star created 1,800 years ago after the collision of two distant suns is set to appear in the night sky for the first time – as the light from the crash finally reaches the Earth...."

    Future star collision to let us see 1800 years into the past

    The year's best astronomy photos
    The winning images from this year's competition have now been announced, with Artem Mironov's vibrant clouds of dust and gas in the Rho Ophiuchi Cloud Complex scooping first place.

    The place spacecraft go to die

    China's Tiangong-1 space station is currently out of control and expected to fall back to Earth next year. But not in the remote place where many other spacecraft end their days.

    Explorers and adventurers often look for new places to conquer now that the highest peaks have been climbed, the poles reached and vast oceans and deserts crossed.

    Some of these new places are called the poles of inaccessibility. Two of them are particularly interesting.
    One is called the continental pole of inaccessibility - it's the place on Earth furthest from the ocean. There is some debate as to its exact position but it's considered by many to be near the so-called Dzungarian Gate - a mountain pass between China and Central Asia.

    The equivalent point in the ocean - the place furthest away from land - lies in the South Pacific some 2,700km (1,680 miles) south of the Pitcairn Islands - somewhere in the no-man's land, or rather no-man's-sea, between Australia, New Zealand and South America.

    [thank heavens for that!]

    Tiangong-1's orbit is decaying as it heads towards re-entry. But Chinese engineers have lost control of it and cannot fire its thrusters to bring it down in the South Pacific.

    Instead it will come down somewhere between 42.8 degrees north and south. That's between the latitude of northern Spain and southern Australia, and we won't be able to be more precise than that until just a few hours before it burns up.

    Tiangong-1 is one space station that probably won't join its companions in the remote South Pacific.

    shame the constalations arent joined up with white lines like in the star charts. would make it easier to work out wot I was looking at. I'm in a dark sky area this week & looking at the stars wiv me bins is mind blowing.
