I love astronomy and this is definitely very exciting to hear about! Astronomers
are looking at a merger
of galaxy clusters!
The cluster spans 3 million light-years across and, if it were visible in
the sky, it would cover half of the Moon. It appears to be made up of two smaller
galaxy clusters, one crammed with 1000 galaxies and the other with 300. Shock
waves caused by the merger, which may have begun 300 million years ago. has
heated gas in the clusters to extreme temperatures - about 100 million °C.
Here's something I'm sure you'll learn more about in the very near future...
Spit.
A new plague of unwanted messages threatens internet users, according to
a US company. Spam and spim - spam by instant messenger – are about to
be joined by "spit" - spam over internet telephony. Qovia, based in
Frederick, Maryland, have recently filed two patent applications for technology
to thwart spit.
