Phys.org / Webb brings dying star's energetic display into full focus
Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from the James Webb Space Telescope. Its rings, which are only detected in infrared light, now look like fuzzy ...
Phys.org / Evidence of dark matter-free dwarf galaxy challenges conventional galaxy formation models
Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. This ultra-diffuse galaxy is located on the outskirts of the Fornax Cluster, ...
Phys.org / In science communication, realistic avatars may foster more trustworthiness than cartoon-like ones
On TikTok there are exceptional "testimonials" like Nikola Tesla or Marie Curie delivering short science-related messages that have garnered millions of views. This is just one of many examples where AI-generated avatars ...
Phys.org / A slowly spinning universe could solve the Hubble tension
A new study in Monthly Notices of the Royal Astronomical Society by researchers including István Szapudi of the University of Hawaiʻi at Mānoa Institute for Astronomy suggests the universe may rotate—just extremely slowly. ...
Phys.org / Scientists observe exotic quantum phase once thought impossible
A team of Rice University researchers reported the first direct observation of a surprising quantum phenomenon predicted over half a century ago, opening pathways for revolutionary applications in quantum computing, communication, ...
Phys.org / New sub-Neptune exoplanet orbiting nearby star detected
Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with ...
Phys.org / Crows can recognize geometric regularity
A trio of animal physiologists at the University of Tübingen, in Germany, has found that at least one species of crow has the ability to recognize geometric regularity. In their study published in the journal Science Advances, ...
Phys.org / Lucy spacecraft prepares for second asteroid encounter
NASA's Lucy spacecraft is six days and less than 50 million miles (80 million km) away from its second close encounter with an asteroid; this time, the small main belt asteroid Donaldjohanson.
Phys.org / ATLAS gets under the hood of the Higgs mechanism
The detection of longitudinally polarized W boson production at the Large Hadron Collider is an important step towards understanding how the primordial electroweak symmetry broke, giving rise to the masses of elementary particles.
Phys.org / Half of the universe's hydrogen gas, long unaccounted for, has been found
Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short of the total matter produced in the Big Bang 13.6 billion years ago. In fact, more than half ...
Phys.org / Live imaging captures DNA folding in sperm cells for the first time
Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University and colleagues have achieved a breakthrough in understanding sperm DNA packaging. Using high-speed atomic force microscopy (HS-AFM), they captured ...
Phys.org / Archaeologists discover historical link between inequality and sustainability
A study led by Professor Dan Lawrence, of Durham University in the UK, found that across 10 millennia, more unequal distributions of wealth correlated with longer-term human settlement. However, the team are keen to stress ...
