This “forbidden” exoplanet has an atmosphere scientists can’t explain - Science Daily

Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy of measurements or introduce errors in controls. Even at the minute level of quantum phenomena, fluctuations are considered undesirable. But what if some fluctuations can be made useful? A theoretical study from the Indian Institute of Technology Bombay (IIT Bombay) shows that structured quantum fluctuations in light can be used to sense and generate useful quantum optical signals.

The Futura Team represents the pulse of Futura’s editorial department, bringing together a collective expertise dedicated to the dissemination of scientific knowledge. Rather than the work of a single author, every article published under this signature is the result of a rigorous collaborative process involving journalists, editors, and fact-checkers. Specializing in news analysis via desk research and international wire services, the team focuses on transforming raw information into accessible, verified content. This curation and synthesis process ensures constant monitoring of technological innovations and major scientific breakthroughs. By cross-referencing sources and conducting multiple rounds of peer review, the Futura Team guarantees scientific accuracy and pedagogical clarity. This collective signature serves as a hallmark of trust, providing reactive, cross-disciplinary information at the forefront of current events The slope was off-limits because of falling rocks. What the climbers photographed there has split paleontologists ever since.

New research suggests that a perplexing signal created by a pair of colliding black holes may have been warped by a space-time phenomenon known as gravitational lensing. This theory could finally explain the "impossible" size of the merging singularities, but it also poses a new problem.

The EAC-1 (top row), EAC-2 (middle row), and EAC-3 (bottom row) designs shown to relative scale. The left column shows the stowed, launch configuration for each architecture and its fit inside the representative Starship fairing. The middle column is looking down the telescope boresight, and the right column shows the top-down view. A series of well-established deployments are used to transform between the stowed and operational configurations. -- astro-ph. IM [astro-ph. IM]. A wavefront-sensor (WFS) prediction can select the photon measurement before detection or condition its likelihood afterward.

Webb observations reveal a hotter, more extended evening edge in the atmosphere of the giant exoplanet WASP-17b. A method called transmission strings maps atmospheric differences around the planet’s apparent outline during transit. The inferred temperature contrast is about 650 kelvin, while water and carbon dioxide abundances remain broadly consistent around the limb. One edge of WASP-17b stretches farther into space than the other. Around this swollen gas giant, intense heating and atmospheric circulation produce differences that disappear when astronomers treat the entire atmosphere as one uniform ring. A new analysis has recovered some of that missing structure from starlight filtered through the planet’s atmosphere. The findings, published in Nature Astronomy, concern a hot Jupiter roughly 1,300 light-years from Earth. A team co-led by Cornell University and the University of Bristol applied a method called transmission strings to James Webb Space Telescope observations. The approach traces atmospheric properties at different positions around the planet’s apparent edge.
