Early Chemistry of a Star’s Protoplanetary Disc Shapes Life-Friendly Atmospheres

A new study reveals that the chemistry of a star’s protoplanetary disc could influence the later composition of planetary atmospheres. Born in a disc of gas and rubble, planets eventually come together as larger and larger pieces of dust and rock stick together. They may be hundreds of light-years away from us, but astronomers can […]

Amateur Astronomers Combine Data to Reveal New Images of Galaxies

Amateur astronomers and astrophotographers have combined their optical data with the data from some of the world’s most sophisticated space telescopes to reveal new images of galaxies M101, M81, Centaurus A, and M51. Long before the term “citizen science” was coined, the field of astronomy has benefited from countless men and women who study the […]

Astronomers Reveal Relationship Between the Color of a Galaxy and the Size of Its Bulge

Using data from the Sloan Digital Sky Survey to group together over half a million galaxies of all different colors, shapes, and masses, new research reveals a relatively simple relationship between the color of a galaxy and the size of its bulge – the more massive the bulge the redder the galaxy. The universe we […]

Smartphone Readable Microparticles Could Crack Down on Counterfeiting

Smartphone Readable Microparticles

MIT chemical engineers invented smartphone-readable microparticles that can be used to verify goods and crack down on counterfeiting. By encoding these particles with different colored stripes, they can generate vast quantities of unique combinations that can be used to tag products. Some 2 to 5 percent of all international trade involves counterfeit goods, according to […]

Researchers Reveal New Method for Studying Binary Star Systems

Using data from the Kepler spacecraft, researchers from the University of Washington confirm the first “self-lensing” binary star system. What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer. Working with UW astronomer Eric Agol, doctoral […]

Microgravity Mimics Aging in Immune Cells

Human-T-Lymphocyte (T Cell)

Changes in T-cell behavior quickly occur in space, allowing researchers to more effectively study genetic and molecular changes associated with aging-related immune suppression. Telling someone to “act your age” is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to […]

Hubble Views Globular Cluster Messier 5

This newly released Hubble image shows globular cluster Messier 5, which is located 24,500 light-years away. This sparkling jumble is Messier 5 — a globular cluster consisting of hundreds of thousands of stars bound together by their collective gravity. But Messier 5 is no normal globular cluster. At 13 billion years old it is incredibly […]

Quantum Dots Make Photovoltaic Solar-Panel Windows Possible

A new study from Los Alamos National Laboratory and the University of Milano-Bicocca demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy, boosting the output of solar cells and allowing for the integration of photovoltaic-active architectural elements into buildings. A house window that doubles as a solar panel could be […]

SLAC Scientists View Ultrafast Snapshots of Light-Driven Superconductivity

Scientists at SLAC National Accelerator Laboratory’s Linac Coherent Light Source used carefully timed pairs of laser pulses to capture ultrafast snapshots of light-driven superconductivity. A new study pins down a major factor behind the appearance of superconductivity – the ability to conduct electricity with 100 percent efficiency – in a promising copper-oxide material. Scientists used […]

Nearly Completed VPHAS+ Catalog to Include 300 Million Stars

Nearly completed, the VPHAS+ catalog will include stars and nebulae that are as much as 1500 times fainter than the ones in the older catalog, as well as much improved images of all objects. Atomic hydrogen is the lightest and by far most abundant element in the universe. When it is exposed to ultraviolet light, […]

New Technique Provides Near Real-Time Mapping of the Sun’s Interior

Using data from NASA’s Solar Dynamics Observatory, researchers have developed a new technique that opens the door for near real-time mapping of the sun’s roiling interior. Like a balloon bobbing along in the air while tied to a child’s hand, a tracer has been found in the sun’s atmosphere to help track the flow of […]

Kepler Discovers Earth-Size Planet Orbiting a Star in the ‘Habitable Zone’

Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone,” confirming that Earth-size planets exist in the habitable zones of other stars and signaling a significant step closer to finding a world similar to Earth. Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in […]
