NASA announced the nine instruments selected for the space probe that will explore Europa, a large Jupiter’s moon. The interest in a mission of this type has grown over the years, since the Galileo space probe found evidence of the existence of Europa’s subsurface ocean. The new mission will try to determine whether that ocean contains life forms.
The most detailed image ever obtained of the Medusa Nebula was taken using ESO’s VLT (Very Large Telescope) in Chile. It reveals in a much better way the filaments of glowing gas that make it up. Those are snake-like filaments that led to the nickname Medusa with which is commonly known, inspired by the myth of the creature with snakes in place of hair. This nebula shows what might happen to the Sun some billion years in the future.
An article published in the journal “Astrophysical Journal” describes the discovery of the brightest galaxy of the universe made using data from NASA’s space telescope WISE. Known as WISE J224607.57-052635.0, it emits light equivalent to that of over 300 trillion suns. It belongs to the ELIRG (Extremely Luminous Infrared Galaxy) class recently identified thanks to WISE.
CERN announced that the Large Hadron Collider (LHC) successfully tested particle collisions at the highest energy level possible after its updates, 13 TeV (13 trillion electron volts). After the restart of the enormous particle accelerator took place at Easter, the energy levels were gradually increased and in Wednesday’s late night the collisions reached the maximum energy.
A little while ago the SpaceX Dragon spacecraft ended its CRS-6 (Cargo Resupply Service 6) mission for NASA splashing down without problems in the Pacific Ocean a little more than 200 km (a little more than 150 miles) off the coast of California. The Dragon left the International Space Station a few hours earlier.
