The Milky Way’s Tumultuous
Heart Revealed In X-Rays:
Scientists
have captured an image through X- rays that has seized every component in our
galaxy. They include black holes, nebulae, supernovae, young stars, old stars,
dwarf planets, etc. Quite beautiful, isn't it?

New Data From Antarctic Detector
Firms Up Cosmic Neutrino Sighting:
The
word ‘neutrino’ is derived from the Italian word ‘neutron’ meaning neutral. It is
a (neutral) subatomic particle which has a mass of nearly 0. neutrinos rarely
react with normal matter, hence the name. They are high energetic particles
generated in black holes, exploding stars and the cores of galaxies. Since neutrinos
are nearly massless and have no electrical charge, they cannot be detected
directly. They are only detected when they clash with other particles to form
secondary particles. “Those high-energy neutrinos, scientists believe,
are created deep inside some of the universe’s most violent phenomena. The
particles created in these events, including neutrinos and cosmic rays, are
accelerated to energy levels that exceed the record-setting earthbound
accelerators such as the Large Hadron Collider (LHC) by a factor of more than a
million.” This discovery is a
great deal because it kicks starts a new form of astronomy.
