But on the morning of the second leaders» debate (on Sky News and
Radio 4 at 8 pm tonight) it would
appear that Fleet Street is now moving to
burst the Clegg bubble and bring him back down to earth, not only by putting Lib Dem policy under serious scrutiny for the first time, but also by delving into Clegg's personal record:
An unknown object that
appears close to an expanding cloud of matter from a supernova (top) spat out five strong
radio bursts in 2002 (bottom).
Only a few fast
radio bursts have ever been detected, and most
appear as one - off events.
The change in the
burst's brightness
appears to be exactly the same at
radio and optical frequencies; this can happen, say Garnavich and his collaborators Avi Loeb and Kris Stanek from the Center for Astrophysics in Cambridge, Massachusetts, only if part of the expanding ring passed behind a star located exactly between Earth and the ring itself.
Instead, they found a strange
burst of
radio noise recorded in 2001 that
appeared to originate well beyond one of the satellite galaxies that orbit the Milky Way.

One important clue to understanding the origin of the
radio bursts is that the emission
appears to be «coherent,» Hyman said.
They hope to localize more
bursts to see whether they usually live in dwarf irregular galaxies, and whether they all
appear alongside steady
radio sources, both of which would support the newborn - magnetar theory.
