Transiting exoplanet with longest known year: 704 Earth days
Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods.

Mysterious dance of dwarf galaxies may force a cosmic rethink
The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The researchers believe the answer may be hidden in some currently unknown physical process that governs how gas flows in the universe, although, as yet, there is no obvious mechanism that can guide dwarf galaxies into narrow planes.

Oceans vital for possibility for alien life
Researchers have made an important step in the race to discover whether other planets could develop and sustain life. New research shows the vital role of oceans in moderating climate on Earth-like planets Until now, computer simulations of habitable climates on Earth-like planets have focused on their atmospheres. But the presence of oceans is vital for optimal climate stability and habitability.

Newfound Alien Planet Has Longest Year Known for Transiting World
The newly discovered exoplanet Kepler-421b ? which crosses the face of, or transits, its host star from Earth's perspective ? takes 704 days to complete one orbit. Thus, it has the longest year known for any transiting alien world.

Hubble traces the halo of a galaxy more accurately than ever before
Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.

NASA's Orion spacecraft crew module has been stacked on the service module inside the Operations and Checkout Building at Kennedy Space Center—renamed on July 21, 2014 as the Neil Armstrong Operations and Checkout Building in honor of the legendary astronaut and first man to set foot on the moon, Neil Armstrong.

Simulated 'engine of explosion' observed in supernova remnant
Back in 2003, researchers using the Oak Ridge Leadership Computing Facility's (OLCF's) first supercomputer, Phoenix, started out with a bang. Astrophysicists studying core-collapse supernovae—dying massive stars that violently explode after running out of fuel—asked themselves what mechanism triggers explosion and a fusion chain reaction that releases all the elements found in the universe, including those that make up the matter around us?

Researchers offer possible explanation for lack of radiation flash from gas cloud interaction with Milky Way black hole
(Phys.org) —A team of researchers at the Max Planck Institute in Germany has offered a possible explanation for the lack of fireworks during the interaction between a gas cloud and the black hole believed to be at the center of the Milky Way Galaxy. In their paper uploaded to the prepress server arXiv, the researchers suggest that the expected fireworks didn't happen because the gas cloud is actually a dense clump that is part of a continuous stream of matter and because of that it only brushed the black hole rather than gushed into it.
