The mystery of the IBEX ribbon
Astronomers are a step closer to finally solving the mystery of the IBEX ribbon spotted at the edge of the solar system eight years ago. New computer simulations and data from NASA’s IBEX spacecraft are pointing to ionized solar wind particles streaming back into the solar system after interacting with interstellar space galactic magnetic fields.
Invisible gas clouds appear shaped like dark noodles
Astronomers have been given their best view yet of the giant interstellar gas clouds which make up a significant amount of the Milky Way galaxy’s matter. The invisible structures known as Extreme Scattering Events are high density lumps in the thin electrically charged gas between the stars in our Galaxy and appear to be shaped like noodles, lasagna sheets or possibly even hazelnuts.
New Subatomic particle discovered
Scientists at Fermilab have discovered a new particle—the latest member to be added to the exotic species of particles known as tetraquarks. The new discovery by the DZero experiment is of the first tetraquark candidate composed of four different quark flavours.
Supernova puzzle close to being solved
New observations using the Hubble Space Telescope have confirmed that a supernova which exploded more than three years ago is continuing to shine far brighter than expected. The supernova known as SN 2012cg could have important implications for astronomy’s ability to measure cosmic distances across the universe.
