Published NASA's Webb detects carbon dioxide in exoplanet atmosphere
(via sciencedaily.com) NASA's James Webb Space Telescope has captured the first clear evidence for carbon dioxide in the atmosphere of a planet outside the solar system. This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet. The finding offers evidence that in the future Webb may be able to detect and measure carbon dioxide in the thinner atmospheres of smaller rocky planets.
Published An extrasolar world covered in water?
(via sciencedaily.com) An international team of astronomers has discovered an exoplanet that could be completely covered in water.
Published ESO telescope images a spectacular cosmic dance
(via sciencedaily.com) ESO's Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision -- the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its center lies the closest pair of supermassive black holes ever found, two objects that are destined to coalesce into an even more massive black hole.
Published Black hole collisions could help us measure how fast the universe is expanding
(via sciencedaily.com) Astrophysicists have laid out a method for how to use pairs of colliding black holes to measure how fast our universe is expanding -- and thus help illuminate how the universe evolved, what it is made out of, and where it's going.
Published Ready for its close-up: New technology sharpens images of black holes
(via sciencedaily.com) Using new computational algorithms, scientists have measured a sharp ring of light predicted to originate from photons whipping around the back of a supermassive black hole.
Published Astronomers confirm star wreck as source of extreme cosmic particles
(via sciencedaily.com) NASA's Fermi Gamma-ray Space Telescope confirms one supernova remnant as a launch site for some of our galaxy's highest-energy protons.
Published First stars and black holes
(via sciencedaily.com) Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes. Did primordial black holes help or hinder formation of the universe's first stars, eventually born about 100 million years later?
Published Stars determine their own masses
(via sciencedaily.com) Using new simulations, astrophysicists discovered that star formation is a self-regulatory process. In other words, stars themselves set their own masses. This helps explain why stars formed in disparate environments still have similar masses.
Published Planet formation: ALMA detects gas in a circumplanetary disk
(via sciencedaily.com) Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What's more, the detection also suggests the presence of a very young exoplanet.
Published Signs of disturbance in nearby dwarf galaxies indicate an alternative gravity theory
(via sciencedaily.com) According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth's second closest galaxy cluster -- known as the Fornax Cluster -- are free of such dark matter halos.
Published New chip-based beam steering device lays groundwork for smaller, cheaper lidar
(via sciencedaily.com) Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar systems. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is used in a wide range of applications such as autonomous driving, free-space optical communications, 3D holography, biomedical sensing and virtual reality. Researchers describe their new chip-based optical phased array (OPA) that solves many of the problems that have plagued previous OPA designs.
Published Augmented reality could be the future of paper books, according to new research
(via sciencedaily.com) Augmented reality might allow printed books to make a comeback against the e-book trend, according to researchers.
Published Out with a bang: Explosive neutron star merger captured for the first time in millimeter light
(via sciencedaily.com) Scientists have recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star. The team also confirmed this flash of light to be one of the most energetic short-duration gamma-ray bursts ever observed, leaving behind one of the most luminous afterglows on record.
Published Engineers repurpose 19th-century photography technique to make stretchy, color-changing films
(via sciencedaily.com) A new technique opens a door to manufacturing of pressure-monitoring bandages, shade-shifting fabrics, or touch-sensing robots
Published Scientists reveal distribution of dark matter around galaxies 12 billion years ago -- further back in time than ever before
(via sciencedaily.com) Using Cosmic Microwave Background (CMB) radiation instead of visible light allows scientists to determine the distribution of dark matter several billion years earlier than previously possible.
Published Super-Earth skimming habitable zone of red dwarf
(via sciencedaily.com) A super-Earth planet has been found near the habitable zone of a red dwarf star only 37 light-years from the Earth. This is the first discovery by a new instrument on the Subaru Telescope and offers a chance to investigate the possibility of life on planets around nearby stars. With such a successful first result, we can expect that the Subaru Telescope will discover more, potentially even better, candidates for habitable planets around red dwarfs.
Published Fiddler crab eye view inspires researchers to develop novel artificial vision
(via sciencedaily.com) Artificial vision systems are implemented in motion sensing, object detection, and self-driving vehicles. However, they are not suitable for changing external environments and are limited to a hemispherical field-of-view (FOV). Addressing this issue, researchers have now developed a novel artificial vision with 360-degree FOV that can image both terrestrial and aquatic environments. The system, modeled after the eye structure of the fiddler crab, could help realize the all-weather vision and panoramic object detection.
Published Space study offers clearest understanding yet of the life cycle of supermassive black holes
(via sciencedaily.com) Supermassive black holes with varying light signatures are actually in different stages of the life cycle.
Published Heaviest neutron star to date is a 'black widow' eating its mate
(via sciencedaily.com) Millisecond pulsars spin far more rapidly than expected for a collapsed star. The best chance to study these neutron stars is to find a black widow system where the pulsar has evaporated and eaten much of its companion star. The Keck I telescope was just able to capture spectra of one such companion, allowing astronomers to weigh its pulsar. It's the heaviest found to date, and perhaps near the upper limit for a neutron star.
Published Halos and dark matter: A recipe for discovery
(via sciencedaily.com) About three years ago, a team of astronomers went looking for the universe's missing mass, better known as dark matter, in the heart of an atom. Their expedition didn't lead them to dark matter, but they still found something that had never been seen before, something that defied explanation. Well, at least an explanation that everyone could agree on.
