Perseverance rover snaps selfie in western frontier of Mars

NASA’s Perseverance Mars rover recently took a self-portrait against a sweeping backdrop of ancient Martian terrain at a location the science team calls Lac de Charmes. Assembled from 61 individual images, the selfie shows Perseverance training its mast on a rocky outcrop on which it had just made a circular abrasion patch, with the western […]

TIME instrument unlocks faint signals from early galaxies across vast stretches of sky

Cornell astronomers are deploying a new instrument that grants them, for the first time, a better view of the universe’s earliest galaxies, which can’t be observed individually with traditional ground- or space-based telescopes.

‘Calm’ galaxy cluster hides a violent cosmic scene that took 4 billion years to settle

The galaxy cluster Abell 2029 is sometimes described as “the most relaxed cluster in the universe.” This moniker does not arise from some sort of mellow vibe, but rather because of how calm and undisturbed the superheated gas that pervades the cluster appears to be.

AI surrogate accelerates nonlinear optics simulations by orders of magnitude

Simulating the nonlinear optical physics that underlies ultrafast laser systems is computationally demanding—a practical bottleneck in settings that require rapid feedback. A study by researchers at Stanford University, University of California, Los Angeles (UCLA), and SLAC National Accelerator Laboratory introduces a deep learning surrogate that delivers orders-of-magnitude acceleration over conventional simulation methods, while maintaining high […]

Gravitational waves from colliding black holes may allow detection of dark matter

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, gravitational waves rippling across space and time could carry an imprint of that dark […]

Brighter red micro-LEDs could help solve full-color display stability challenge

Researchers at The University of Osaka, in collaboration with Ritsumeikan University, have demonstrated that growing europium-doped gallium nitride (Eu-doped GaN) on a semipolar crystal plane dramatically improves red light emission. The team found that this approach selectively promotes the formation of highly efficient Eu luminescent centers, resulting in red emission intensity more than 3.6 times […]

80 years after the Trinity nuclear test, scientists identify new molecule-trapping crystal formed in the blast

Matter behaves strangely under extreme conditions, and often, remnants of these behaviors are left behind even when conditions return to normal. The Trinity nuclear test in 1945 left behind such remnants, and now, 80 years after the explosion, researchers have identified another unique example of what happens when various materials are heated to temperatures exceeding […]

Quantum circuit test finally exposes what has been warping performance

Quantum computers could someday solve pressing problems that are too convoluted for classical computers, such as modeling complex molecular interactions to streamline drug discovery and materials development.

Scientists use AI to interpret the sun’s acoustic heartbeat

A new AI-based approach that can “hear” inside the sun could give vital signs of the solar disturbances that have significant effects in near-Earth space and on human activities. The solar cycle is an approximate 11-year period during which the sun’s magnetic activity rises and falls. The cycle begins relatively calmly. However, as it progresses, […]

Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years

By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the most persistent QPOs detected in the optical band. The finding was reported in a paper published April 30 […]

New quantum protocol breaks distance and speed barriers in fiber networks

Scientists at the University of Science and Technology of China have successfully deployed a multi-mode quantum relay network, achieving matter–matter entanglement over 14.5 kilometers, according to media reports.
