The mystery at
the heart of an unexplained, bright point of gamma-ray light in the sky has
been solved: There's a deadly spider star flaying a second, wimpier star to
bits, sending out rapid-fire bursts of gamma radiation in the process.
The fastest-spinning among them are millisecond pulsars. When a
millisecond pulsar is locked in a rare, tight orbit with a lightweight star, it
slowly shreds its partner to bits with each rotation. These binary cannibals
are known as black widow or redback stars. Now, with the help of citizen
scientists, a team of researchers has revealed a new redback at the heart of a
bright system known as PSR J2039–5617.
It is lonely in the universe.
Space signals tend to be false alarms. Not even the infamous wow-signal was probably cause by a comet,
not aliens
New Scientist has said
that aliens are more likely than God..
But only if we a priori
rule out the God who in the beginning created
everything.
Life cannot create itself.
