How to thermally cloak an object
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter......»»
Researchers measure the gravity exerted by a 90 milligram object
We've measured the pull between two gold spheres, each 2 millimeters across. Enlarge / The experimental setup. (credit: Tobias Westphal / University of Vienna) Gravity may feel like one of the most familiar forces, but it's actually among thos.....»»
Most distant quasar with powerful radio jets discovered
With the help of the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a "radio-loud" quasar—a bright object wi.....»»
Hubble captures a wandering comet passing through the Trojan asteroids
Hubble Space Telescope snapped an image of an object called P/2019 LD2 which is part-comet, part-asteroid......»»
FBI Confirms Report of "Long, Cylindrical" UFO "Moving Really Fast" Over New Mex
An anonymous reader shares a PopularMechanics report: An American Airlines flight crew encountered an unidentified flying object over New Mexico on February 21. American Airlines has confirmed the strange incident, during which a "long, cylindrical o.....»»
Comet makes a pit stop near Jupiter"s asteroids
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Tro.....»»
Vertica in Eon Mode Now Supports Scality for Even Greater Choice
We are pleased to announce the general availability of Vertica in Eon Mode for Scality RING S3 object storage on the HPE Apollo 4000 platform The post Vertica in Eon Mode Now Supports Scality for Even Greater Choice appeared first on Vertica......»»
Continental invests in object recognition startup
The German supplier has bought a minority stake in Recogni, which is working on object recognition in real time based on artificial intelligence......»»
NASA"s Swift helps tie neutrino to star-shredding black hole
For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, they traced the neutrino t.....»»
New "metalens" shifts focus without tilting or moving
Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object in view is a single cell, the page of a book, or a far-off galaxy......»»
Research reveals stellar kinematics of the galactic disc
By using a sample of 118945 red giant branch (RGB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, Dr. Wu Yaqian from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) invest.....»»
Comet from edge of solar system killed the dinosaurs: study
Sixty-six million years ago, a huge celestial object struck off the coast of what is now Mexico, triggering a catastrophic "impact winter" that eventually wiped out three-quarters of life on Earth, including the dinosaurs......»»
ASASSN-18aan is an unusual cataclysmic variable, study finds
An international team of astronomers has performed photometric and spectroscopic observations of a binary star system known as ASASSN-18aan and have found that the object is an unusual cataclysmic variable with a relatively long orbital period. The f.....»»
At 132 astronomical units, "Farfarout" is the most distant object we"ve ever found in the solar system
The team has since learned that Farfarout resides 132 astronomical units (AUs) from the Sun. A single AU is defined as the distance from the center of the Earth to the center of the Sun, or about 91.757 million miles. For comparison, dwarf planet Plu.....»»
Moiré patterns facilitate discovery of novel insulating phases
Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can suppress electrical conduc.....»»
Astronomers confirm orbit of most distant object ever observed in our solar system
A team of astronomers, including associate professor Chad Trujillo of Northern Arizona University's Department of Astronomy and Planetary Science, have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the mos.....»»
Physicists finesse the storing of light to create rainbows of color
In nature, as in everyday life, we are surrounded by resonance—the phenomenon that describes how each object has a frequency that it prefers to vibrate at. The note of a guitar string and the sound of Big Ben chiming are examples of resonance......»»
Thick lithosphere casts doubt on plate tectonics in Venus"s geologically recent past
At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the.....»»
Researchers create powerful unipolar carbon nanotube muscles
For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or polymer yarns. When thermally.....»»
Astronomers discover new candidate redback millisecond pulsar
Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting X-ray emission that consists.....»»
Spreading focus for better imaging
Extreme Ultraviolet (EUV) light in microscopy offers the advantage of obtaining a high-resolution image combined with spectral information about the object under study. However, because EUV microscopy uses diffraction instead of lenses, imaging with.....»»
