Researchers look for dark matter close to home

Mar 27, 2020 (SPX)

A new study from the University of Michigan, Lawrence Berkeley National Laboratory (Berkeley Lab) and University of California, Berkeley has ruled out dark matt...

Advanced 'super-planckian' material exhibits LED-like light when heated

Mar 25, 2020 (SPX)

In 1900, Max Planck first mathematically described a pattern of radiation and ushered in the quantum era with the assumption that energy can only exist in discr...

Shining light on sleeping cataclysmic binaries

Mar 25, 2020 (SPX)

China's FAST telescope identifies 114 pulsars

Mar 24, 2020 (XNA)

The gigantic telescope carried out nearly 1,000 hours of observation from Jan. 1 to March 23, 2020, according to the FAST Operation and Development Center of th...

Star formation project maps nearby interstellar clouds

Mar 24, 2020 (SPX)

We know that stars such as the Sun are born from interstellar gas clouds. These interstellar gas clouds are difficult to observe in visible light, but emit stro...

Photons and electrons one on one

Mar 23, 2020 (SPX)

The quantum concept revolutionised physics. The photoelectric effect, for its part, has been explored in ever greater detail, and is nowadays exploited in appli...

Quasar tsunamis rip across galaxies

Mar 20, 2020 (SPX)

Hubble astronomers found that the region around the black hole emits so much radiation that it pushes out material at a few percent the speed of light (a speed ...

New telescope design could capture distant celestial objects with unprecedented detail

Mar 19, 2020 (SPX)

"A multi-field hypertelescope could, in principle, capture a highly detailed image of a star, possibly also showing its planets and even the details of the plan...

Scientists describe and emulate new quantum state of entangled photons

Mar 19, 2020 (SPX)

The method relies on the analogy: instead of expensive experiments with quantum systems of two or more entangled photons, the researchers have used resonant ele...

'Hypertelescope' camera could revolutionize celestial photography

Mar 19, 2020 (UPI)

The camera would potentially allow hypertelescopes, small units arranged in multi-field patterns, instead of standard telescopes with a single and massive mirro...

Proposals selected to study volatile stars, galaxies, cosmic collisions

Mar 17, 2020 (SPX)

Following detailed evaluations, the agency intends to select two proposals in 2021 to be the next astrophysics missions under the Explorers Program. The selecte...

Scientists discover pulsating remains of a star in an eclipsing double star system

Mar 17, 2020 (SPX)

The discovery of the first ever pulsating white dwarf star in an eclipsing binary by physicists at Sheffield means the team can see how binary evolution has aff...

Astrophysicists utilize polarization to watch quasars

Mar 16, 2020 (SPX)

The authors of the recent study in the Monthly Notices of the Royal Astronomical Society managed to distinguish between the light coming from different parts of...

Citizen scientists enlisted to chart galaxies

Mar 13, 2020 (UPI)

Researchers at the North Carolina Museum on Natural Sciences in Raleigh used software and tracings of known spiral galaxies on paper, and found that no artifici...

Slime mold simulations map the Universe's dark matter

Mar 11, 2020 (SPX)

The single-cell organism, known as slime mold (Physarum polycephalum), builds complex filamentary networks in search of food, finding near-optimal pathways to c...

How big is a neutron star

Mar 11, 2020 (SPX)

Their results, which appeared in Nature Astronomy on March 9, are more stringent by a factor of two than previous limits and show that a typical neutron star ha...

Turbulent convection at the heart of stellar activity

Mar 10, 2020 (SPX)

This process is called convection. At the same time, the star's rotation, which depends on stellar latitude, introduces shear movements. Together, both processe...

'Strange' glimpse into neutron stars and symmetry violation

Mar 10, 2020 (SPX)

The results, just published in Nature Physics, could only be obtained at a powerful ion collider such as RHIC, a U.S. Department of Energy (DOE) Office of Scien...
