Dying stars could seed interstellar medium with carbon nanotubes
Jun 19, 2022 (SPX)
In a paper accepted for publication in the Journal of Physical Chemistry A, researchers from the University of Arizona suggest a surprisingly simple explanation...
Webb set to begin science operations
Jun 16, 2022 (SPX)
But it has taken nearly eight months of travel, setup, testing and calibration to make sure this most valuable of telescopes is ready for prime time. Marcia Rie...
Mysterious 'blue blobs' reveal a new kind of star system
Jun 16, 2022 (SPX)
The new stellar systems contain only young, blue stars, which are distributed in an irregular pattern and seem to exist in surprising isolation from any potenti...
One step closer to understanding the Milky Way
Jun 16, 2022 (SPX)
Gaia observed and measured approximately 1.8 billion celestial objects for this purpose. By the expected end of the mission in 2025, the largest and most accura...
NASA's Chandra catches pulsar in X-ray speed trap
Jun 16, 2022 (SPX)
Pulsars are rapidly spinning neutron stars that are formed when some massive stars run out of fuel, collapse, and explode. This pulsar is racing through the rem...
Tracing The Remnants Of Andromeda's Violent History
Jun 14, 2022 (SPX)
Galaxies grow by accreting material from nearby objects-other galaxies and dense clumps of stars called globular clusters-often in the aftermath of a catastroph...
Probing high-energy neutrinos with an IceCube
Jun 14, 2022 (SPX)
Neutrinos are puzzling particles; they are similar in many ways to electrons, but have no charge and no, or a very tiny mass. Scientists have suggested many ast...
Millisecond Pulsars can explain the Gamma-ray Excess in the Milky Way center
Jun 14, 2022 (SPX)
Back in 2009, gamma-ray data from the Fermi-Large Area Telescope revealed an unexplained, apparently diffuse, signal from the center of the Milky Way. The origi...
Gaia sees strange stars in most detailed Milky Way survey to date
Jun 14, 2022 (ESA)
Gaia is ESA's mission to create the most accurate and complete multi-dimensional map of the Milky Way. This allows astronomers to reconstruct our home galaxy's ...
Twin photons from unequal sources
Jun 14, 2022 (SPX)
Many technologies that make use of quantum effects are based on exactly equal photons. Producing such photons, however, is extremely difficult. Not only do they...
Dark matter: should we be so sure it exists? Here's how philosophy can help
Jun 10, 2022 (SPX)
So how can scientists be so sure it exists? Should they be? It turns out philosophy can help us answer these questions. Back in the 1970s, a seminal study by as...
Breakthrough paves way for photonic sensing at the ultimate quantum limit
Jun 10, 2022 (SPX)
Quantum sensing is poised to revolutionise today's sensors, significantly boosting the performance they can achieve. More precise, faster, and reliable measurem...
NuSTAR marks 10 years studying the X-Ray Universe
Jun 10, 2022 (SPX)
Seeing X-Rays Close to Home Different colors of visible light have different wavelengths and different energies; similarly, there is a range of X-ray light, or ...
Emulator reveals the intricacies of light behavior in complex evolving systems
Jun 10, 2022 (SPX)
In non-Hermitian systems, allowed energy values create self-intersecting surfaces with a unique topology and branch points, which are known as exceptional point...
Newly discovered fast radio burst challenges current thinking
Jun 10, 2022 (The Conversation)
Fast radio bursts, or FRBs, are extremely bright pulses of radio waves that come from faraway galaxies. They release as much energy in a millisecond as the Sun ...
Rapid-fire fast radio burst shows hot space between galaxies
Jun 09, 2022 (SPX)
Fast Radio Burst 20190520B - a prolific repeating burst source - was first observed in June 2019 by the Five-hundred-meter Aperture Spherical radio Telescope (F...
Webb: Engineered to Endure Micrometeoroid Impacts
Jun 09, 2022 (SPX)
Thorough analysis and measurements are ongoing. Impacts will continue to occur throughout the entirety of Webb's lifetime in space; such events were anticipated...
An Unexpected Gamma Ray Burst
Jun 09, 2022 (SPX)
Classifying gamma-ray bursts - rapid phenomena amongst the most energetic in the Universe -on the basis of their duration is the most commonly adopted approach ...
New insights into neutron star matter
Jun 09, 2022 (SPX)
These high-energy, astrophysical phenomena feature such extreme conditions that they produce most of the heavy elements, such as silver and gold. Consequently, ...
Hubble captures largest near-infrared image to find universe's rarest galaxies
Jun 07, 2022 (SPX)
"Since its launch more than 30 years ago, the Hubble Space Telescope has led a renaissance in the study of how galaxies have changed in the last 10-billion year...
