Spiral Galaxies May Just be Beginning to Interact Gravitationally

Looking towards the constellation of Triangulum (The Triangle), in the northern sky, lies the galaxy pair MRK 1034. The two very similar galaxies, named PGC 9074 and PGC 9071, are close enough to one another to be bound together by gravity, although no gravitational disturbance can yet be seen in the image. These objects are probably only just beginning to interact gravitationally.

Quasar Helps Study Early Galaxy in Unprecedented Detail

The early galaxies of the universe were very different from today’s galaxies. Using new detailed studies carried out with the ESO Very Large Telescope and the Hubble Space Telescope, researchers, including members from the Niels Bohr Institute, have studied an early galaxy in unprecedented detail and determined a number of important properties such as size, mass, content of elements and have determined how quickly the galaxy forms new stars. The results are published in the scientific journal, Monthly Notices of the Royal Astronomical Society.

New Study Doubles Number of Potentially Habitable Planets Orbiting Red Dwarfs

A new study that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs, the most common type of stars in the universe. This finding means that in the Milky Way galaxy alone, 60 billion planets may be orbiting red dwarf stars in the habitable zone.

Charge-Order Discovered in High-T Superconductor

A recent publication by Johan Chang et al., reports a direct x-ray diffraction observation of charge density wave order in the high-temperature cuprate superconductor YBa2Cu3O6.54.

Common Nonmetallic Solvent Turned into Superconductor

A study led by Washington State University researchers has turned a fairly common nonmetallic solvent into a superconductor capable of transmitting electrical current with none of the resistance seen in conventional conductors.

Researchers Discover Superconductivity in Solid Form of Carbon Disulfide

Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission.

Astronomers Determine True Size and Mass of HD 97658 Exoplanet

Hovering about 70 light-years from Earth –– that's "next door" by astronomical standards –– is a star astronomers call HD 97658, which is almost bright enough to see with the naked eye. But the real "star" is the planet HD 97658b, not much more than twice the Earth's diameter and a little less than eight times its mass. HD 97658b is a super-Earth, a class of planet for which there is no example in our home solar system.
