Hubble Photographs Corkscrew-Shaped String of Pearls and Winds around Two Colliding Galaxies

NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies.

New Technology Could Make Colder Objects in Deep Space More Visible

Too cool and faint, many objects in the universe are impossible to detect with visible light. Now a Northwestern University team has refined a new technology that could make these colder objects more visible, paving the way for enhanced exploration of deep space.

Friction May be the Key to Survival for Distant Planets Traveling in Dangerous Orbits

As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, computer modeling by NASA scientists shows that friction could be the key to survival for some distant Earth-sized planets traveling in dangerous orbits.

Researchers Make Measurements of How Dust Around Supernova Absorbs Light

The origin of cosmic dust in galaxies is still a mystery [1]. Astronomers know that supernovae may be the primary source of dust, especially in the early Universe, but it is still unclear how and where dust grains condense and grow.

Quasiparticle Excitations in Many-Body Quantum Systems Controlled in Trapped Ultracold Ions

Christian Roos' research team at the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences in Innsbruck has established a new experimental platform for investigating quantum phenomena: In a string of trapped ultracold ions they can precisely initialise, control and measure the states and properties of quasiparticle excitations in a many-body quantum system.

NASA's MESSENGER Spacecraft Detects Solar Neutrons Created In Solar Flares

Understanding the sun from afar isn't easy. How do you figure out what powers solar flares – the intense bursts of radiation coming from the release of magnetic energy associated with sunspots – when you must rely on observing only the light and particles that make their way to near-Earth's orbit?

Controversial Signals not from 'Goldilocks Planets'

Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists at Penn State.

New Textbook on Quantum Field Theory in Condensed Matter Physics

Condensed matter physics, through the discoveries of graphene and topological insulators say, realizes in the laboratory many exotic and non-perturbative phenomena that were proposed during the 70's and 80's to probe the physics beyond the standard model of particle physics but have remained illusive to experimental high-energy physics. To appreciate this connection, it is indispensable to master some tools of quantum field theories.

Mercury May be a Relic Left Behind by Collisions in the Early Solar System

Planet Mercury's unusual metal-rich composition has been a longstanding puzzle in planetary science. According to a study published online in Nature Geoscience July 6, Mercury and other unusually metal-rich objects in the solar system may be relics left behind by collisions in the early solar system that built the other planets.

High-Resolution 3-D Model of Expanding Cloud Produced by Eta Carinae Binary System Eruption

In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a team of astronomers has used extensive new observations to create the first high-resolution 3-D model of the expanding cloud produced by this outburst.
