Galaxy J1135 reveals its water map      (via sciencedaily.com) 

Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.

Researchers put a new twist on graphite      (via sciencedaily.com)     Original source 

Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.

Unusual white dwarf star is made of hydrogen on one side and helium on the other      (via sciencedaily.com)     Original source 

In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of helium.

Giant swirling waves at edge of Jupiter's magnetosphere      (via sciencedaily.com) 

A team has found that NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. The waves are an important process for transferring energy and mass from the solar wind, a stream of charged particles emitted by the Sun, to planetary space environments.

When ET calls, can we be sure we're not being spoofed?      (via sciencedaily.com) 

In the search for extraterrestrial intelligence, alien radio signals would be swamped by interference from radio sources on Earth. To confirm, researchers point away from the source and then back. If it's still there, it may be interesting. Researchers have come up with a new method that looks for evidence the signal has passed through the interstellar medium. The technique will boost confidence in any candidate signal discovered in the future.

Hubble views a galactic monster      (via sciencedaily.com) 

The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.

Rare, double-lobe nebula resembles overflowing cosmic 'jug'      (via sciencedaily.com)     Original source 

A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star.
