Neutron stars, or in the early stages of the Big Bang.
New Horizons Prepares to Zoom to PlutoThe New Horizons mission to Pluto has been called "The First Mission to the Last Planet," and it’s the first mission to venture to a "new" planet since the Voyager missions nearly 30 years ago. While New Horizons includes proven technology and a superior launch vehicle, it could be considered to be a 'throw-back’ mission. Some of the scientific instruments on board are named after characters from the 1950’s television show, "The Honeymooners," and the project’s Principal Investigator, Dr. Alan Stern of the Southwest Research Institute, says the mission makes him feel like he’s back in the heyday 1960’s or 1970’s of Space exploration because this mission is all about exploring planets for the first time.
Physicists at MIT have successfully created a new form of matter in their laboratory; a gas that shows superfluidity at higher temperatures. Superfluid gasses, which can flow without resistance, have been created before, but only at very cold temperatures just above Absolute Zero. matter like this could exist in the Universe's most extreme places, like at the heart of black holes, Neutron stars, or in the early stages of the Big Bang.
The Hubble Space Telescope has taken a detailed image of a narrow, dusty ring around nearby star Fomalhaut. Although they can't see it directly, Astronomers think a planet has been tugging at the ring with its gravity. According to researchers, the shape and position of the ring couldn't exist without a planet. This is similar to the twists and knots that NASA's Cassini spacecraft has photographed in Saturn's rings, which are caused by its shepherd moons.
Astronomers have discovered a binary system of a blue giant and a pulsar that operate as a natural particle accelerator, raising the energy levels of simple photons to some of the highest possible energies. The discovery was made by while watching how the pulsar periodically passes through disk of material ejected by the rapidly spinning blue giant. Each time the pulsar sweeps through this material, its intense magnetic field interacts with the ejected material and boosts photons from regular visible light into the range of super-high gamma rays which blast out in all directions. Some of this radiation interacts with our atmosphere, which is why we can detect it here on Earth.
All three MARSIS booms on Mars Express are now fully deployed, and the spacecraft is ready to begin searching Mars for underground sources of ice and water. The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) consists of two 20-metre (66 foot) and one 7-metre (23 foot) boom. Controllers turned on the radar and performed a brief test, but they're still planning on an extensive commissioning phase until July 4, when the instrument will be ready for full operations.
