Hubble Spots Star Explosion Astronomers Can't Explain 154

schwit1 writes: The Hubble Space Telescope has spotted the explosion of a star that does not fit into any theory for stellar evolution. "The exploding star, which was seen in the constellation Eridanus, faded over two weeks — much too rapidly to qualify as a supernova. The outburst was also about ten times fainter than most supernovae, explosions that destroy some or all of a star. But it was about 100 times brighter than an ordinary nova, which is a type of surface explosion that leaves a star intact. 'The combination of properties is puzzling,' says Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland. 'I thought about a number of possibilities, but each of them fails' to account for all characteristics of the outburst, he adds." We can put this discovery on the bottom of a very long list of similar discoveries by Hubble, which this week is celebrating the 25th anniversary of its launch.

    It just means there are more things in space that we don't fully understand yet. But every discovery adds knowledge so we can understand it better.

    • A new type of star !
    • Exactly... astonomers love objects like this because that is a chance to learn something new.
    • i think it just means we need to stop all broadcasts immediately, and pray that the star eater hasn't noticed us yet.

      Really, what objects in space do we fully understand? (I'm not being sarcastic!)

      We don't even fully understand the earth yet, and we can perform direct measurements on it.

        My first thought was "death star".

        Mine too. And from TFA:

        The light that Hubble recorded from the newly found outburst left its distant home galaxy 7.8 billion years ago.

        So it was a long time ago in a galaxy far, far away

      • Or, due to a strange quirk in the space-time continuum, we are actually looking at a future version of our own planet exploding. Don't worry about paradoxes ripping the universe apart, though. The fact that we can see it, means that there's no way to avoid it so there won't be a contradiction. Moving right along.

    The host galaxy is quite far from us. At these distances we can only rely on the red shift which I always thought not to be completely accurate.

    So, if that galaxy is a little bit closer to us then there may not be any mystery here.

  • It's quite simple. First, the star underwent a small blast, too small to be detected, in which it expelled a layer of gas. That gas formed a cloud around the star. Then, there was an ordinary blast. What we saw was the gas cloud being illuminated by the ordinary blast.
    • Except that the two blasts were in different locations. It is possible that it was path time differences between two lensed images.

    Supernova, ordinary nova, and inbetween the newly discovered bossa-nova.

    Why do I have to explain everything every time?

  • What if the star was a normal supernovae but had a companion black hole? Wouldn't that make the light fade prematurely?
  • by ecloud ( 3022 )

    It must have been a champagne supernova in the sky.

  • I looked at the picture given in TFA and it looks to me that the host galaxy of this mysterious non-nova, non-supernova explosion is a background galaxy, lensed by the foreground cluster. It does not look like a member of this foreground cluster.

    I would say, distance estimates for such background galaxies are not particularly easy to make.

  • by pr0t0 ( 216378 ) on Thursday April 23, 2015 @08:31AM (#49535563)

    The thing that struck me about those pics, was the distance the star moved from Jan 2014 to Aug 2014. It appeared to cover roughly 5-10% of the outer diameter of the host galaxy (although the star could be very well be deeper inside the galaxy). The Solar System takes about 226 million years to orbit the Milky Way. This thing appears to orbit at 13 years!

    That makes me think their preliminary analysis of these being two separate events is correct. Although, I am not an astrophysicist, so what do I know?

    • by Anonymous Coward

      No, it's not a moving object. The idea is we could be seeing the same event twice. The image of the galaxy is so distorted by the gravity of foreground objects, that the light from the explosion reaches us along two different paths. One of them is a little longer, so we see a "replay" of the event a little later.

I feared something terrible has happened, but dismissed it as the burrito I had for lunch at the Taco Bell. It does really look like some planet *was* destroyed. mm.. Should learn to trust the Force more.
  • This is more a limitation of the researcher than of the science. This type of Short duration hyperbright nova is not unknown and elsewhere in the literature there are several theories as to their Natural origins. They have been a few detected over the last 50 years but because of their rarity a comprehensive analysis is still wanting.

    So this is not a NEW HUBBLE DISCOVERY, more a OH NICE! you saw one too.
