Gravitational wave observatories to join forces

The LIGO project's two observatories, including this one in Hanford, Washington, US, will join forces with the Virgo observatory in Italy and Germany's GEO 600 to hunt for gravitational waves (Image: LIGO Laboratory)

Brightest supernova discovery hints at stellar collision

The brightest supernova ever seen appears as a dark spot (arrow) in this negative infrared image taken by the Palomar 5-metre telescope. The other dark spot at centre is the host galaxy’s core (Image: E Ofek et al/Caltech/Palomar Observatory)

Supernovae make dark matter bloat

Computer simulations showed that dark matter should be densest at the centres of galaxies, like this one, but observations show it is constant over thousands of light years - supernovae could be to blame (Image: NASA/Hubble Heritage/AURA/STScI)

Chinese and Arabic astronomers left historical documentation of a supernova that occurred in our own galaxy in the year 1006 (SN 1006), and another one 48 years later (SN 1054).

THE task of peering into the cosmos and discovering strange new galaxies sounds like a job for astronomers armed with big and very expensive telescopes.

In the latest in a series of supernova firsts, scientists report in Science that they pinpointed a star that flared in the ultraviolet portion of the spectrum for several hours before blowing itself apart in a supernova.

Good to see that this concept is being studied closer - I've long felt the idea that every sun follows a similar path to destruction a little odd.

Astronomers have at last found definitive evidence that the universe's first dust – the celestial stuff that seeded future generations of stars and planets – was forged in the explosions of massive stars.

Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study published in Science Express.
