The NOνA (NuMI Off-Axis νe Appearance) experiment

By

 The NOνA (NuMI Off-Axis νe Appearance) experiment is a particle physics experiment designed to detect neutrinos in Fermilab's NuMI (Neutrinos at the Main Injector) beam. Intended to be the successor to MINOS, NOνA consists of two detectors, one at Fermilab (the near detector), and one in northern Minnesota (the far detector). Neutrinos from NuMI pass through 810 km of Earth to reach the far detector. NOνA's main goal is to observe the oscillation of muon neutrinos to electron neutrinos. The primary physics goals of NOvA are:[1]

  • Precise measurement, for neutrinos and antineutrinos, of the mixing angle θ23, especially whether it is larger than, smaller than, or equal to 45°
  • Precise measurement, for neutrinos and antineutrinos, of the associated mass splitting Δm232
  • Strong constraints on the CP-violating phase δ
  • Strong constraints on the neutrino mass hierarchy

Russian parliament passed a bill to revoke its ratification of the Comprehensive Test Ban Treaty

By
Relevance:  Russia revokes ratification of nuclear test ban treaty (CTBT) - ICAN But it affirmed that it will  retain its cooperation with the treaty’s verification system and implementing organisation.  Comprehensive Test Ban Treaty: The Comprehensive Test Ban Treaty (CTBT), which opened for signature in 1996, was intended to prohibit all nuclear weapon test explosions. Over 2,000 nuclear tests occurred between 1945 and 1996: the United States (1,000+), the Soviet Union (700+), France (200+), the United Kingdom and China (45 each). As at January 2013, 183 countries had signed the Treaty, of which 158 have also ratified it, including three of the nuclear weapon states (France, the Russian Federation and the United Kingdom). However, 44 specific nuclear technology holder countries must sign and ratify before the CTBT can enter into force. Of these, eight are still missing: China, Egypt, India , Iran, Israel, North Korea, Pakistan and the US. India , North Korea and Pakistan have yet to

Interstellar space and Interstellar Probes ( Voyager and New Horizons Missions )

By
Interstellar Space: Interstellar space is often called the space between the stars, but more specifically, it’s the region between our Sun’s heliosphere and the astrospheres of other stars. Our heliosphere is a vast bubble of plasma – a gas of charged particles – that spews out of the Sun. This outflow is known as the solar wind. The bubble surrounds the Sun and stretches beyond the planets. Both Voyager spacecraft had to travel more than 11 billion miles (17 billion kilometers) from the Sun in order to cross the edge of the heliosphere. This bubble is moving through interstellar space as the Sun orbits the center of the Milky Way galaxy. As our heliosphere plows through space, it creates a bow wave, like the wave formed by the bow of a ship. Kuiper Belt &  Oort Cloud: The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU. Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from
