Could global positioning systems become more precise and provide more accurate details on distances for users to get from point A to point B?
Former Sangamon County Deputy Sean Grayson testified he did not believe a TASER would be effective against Massey and his gun was “the only thing [he] had to stop the threat”
Astronomers have used simultaneous ground-based and space-based observations to measure the temperature and velocity of gas ejected from a young sun-like star. The result showed a two-component ejection consisting of a hot fast component followed by a slower, cooler component. This result is important for understanding how young stars affect their surrounding environment where planets and life may first be forming, and by extension provides insights into the early days of the solar system, Earth, and life on Earth.
In a paper published in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of 2024 with unusual black hole spins. This observation adds an important new piece to our understanding of the most elusive phenomena in the universe.
Meng Dezhao, a Ph.D. student from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, together with his collaborators, has conducted a systematic study of the filamentary structure within the G53 molecular cloud. By combining multi-wavelength observations and simulations, they revealed for the first time that the filament is undergoing an “end-dominated collapse” (EDC), a process that is driving star formation. The paper is published in Astronomy & Astrophysics.
San Bernardino Deputy Andrew Nunez, a six-year employee of the department, was fatally shot while responding to a call of an armed suspect
So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of galaxies and supermassive black holes. But all of it is invisible to us.
Could scientists find life in the clouds of exoplanet atmospheres? This is what a manuscripton the arXiv preprint server hopes to address as a team of researchers investigate how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds.
A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical Review Letters, shows that quantum emitters spaced at subwavelength distances can constructively synchronize their photon emission to produce a bright, very narrow-band light beam, even in the absence of any optical cavity.
Some of these cities existed before written history, and before mankind existed on Earth, at least according to the Bible. But before religion, and before written history, ancient cultures around the world built massive cities, extremely old cities. And when we talk about the oldest cities on Earth, we mean the oldest continuously inhabited cities. Note that different sources have different dates for the cities. Starting off with what many claim is to be the oldest city on the surface of the planet: Jericho.
Traces of habitation: 9000 BC.  Fortifications date to 6800 BC (or earlier), making Jericho the earliest known walled city on the surface of the planet. Jericho is believed to have been continuously inhabited from 9,000 BC. Archaeologists have unearthed more than 20 remains of successive settlements, which are said to go back as far as 11,000 years. Jericho is mentioned in the biblical and is located on the banks of the Jordan River, at the bottom of the slope that leads to the mountainous plateau of Judah, about 8 km from the northern coast of the Dead Sea dry basin, almost 240 m below the level of the Mediterranean Sea and approximately 27 km from Jerusalem. Some say it isn’t Jericho, but Damascus the oldest city on Earth. This ancient city was established sometimes between 10,000 and 8,000 BC, and many authors argue Damascus is the oldest continuously inhabited city on Earth. Consisting of a maze of narrow alleys, the walled city of Damascus characterized by stunning ancient doors leading into radiant courtyards and blank-faced houses. Damascus is commonly known in Syria as ash-Sham and nicknamed the “Jasmine City” it is the capital and the second largest city in Syria after Aleppo. Byblos is believed to have been inhabited since 5,000 BC and is considered by many authors the third oldest continuously inhabited city on Earth. It is believed that it was founded around the year 5000 BC, and according to sources attributed to the Phoenician historian Sanjuniatón, was built by Crono, and was the first Phoenician city. This ancient metropolis was founded by the Phoenicians, despite the fact that its name was given to it by Greeks, who imported large amounts of papyrus from it. In fact, the English word ‘bible’ derives from Byblos. Aleppo in Syria is another ancient city worth including in our list of the oldest continuously inhabited cities on Earth.  According to scholars, this ancient city was inhabited from around 4,300 BC. It’s currently Syria’s most populated city with around 4.4 million inhabitants. The ancient city was founded around 4,300 BC as Halab, and the ruins of the ancient city have not been excavated nor studied by experts. https://twitter.com/historyinpix/status/772677650401943552 During the city’s long history, Aleppo was under Hittite control until around 800 BV, after which it passed to Assyrian, Greek, and Persian hands. It was also occupied by the Romans, Byzantines and Arabs. The city of Aleppo was besieged by the Crusaders and was also invaded by the Mongols and Ottomans. In modern times, the city is a war zone, and most of its history has been lost in conflict. The ancient city of Sidon, another wonder of the ancient world. Considered as one of the most important ancient Phoenician cities, Sidon is located some 40 kilometers south of Beirut. According to experts, archaeological excavations have found evidence of human occupation since 4,000 BC. Before being captured by the Assyrians, this city was the capital of the Elamite Empire. It was also ruled by Cyrus the Great. It currently has a population of around 65,000 people.

An international team of astronomers have employed the James Webb Space Telescope (JWST) to observe a nearby M-dwarf star known as TWA 20. As a result, they detected a large debris disk around this star. The finding was reported in a paper published October 23 on the arXiv pre-print server.
In the beginning, Earth was a violent place with no atmosphere to soften the blow.
In a new milestone for space-enabled semiconductor research, the University of Florida, in collaboration with NASA, MIT, Vanguard Automation, AIM Photonics and Germany’s Fraunhofer Heinrich Hertz Institute, launched a suite of photonic AI chips to the International Space Station aboard JAXA’s HTV-XI spacecraft this weekend.
Astronomers have generated the first three-dimensional map of a planet orbiting another star, revealing an atmosphere with distinct temperature zones—one so scorching that it breaks down water vapor, a team co-led by a Cornell expert reports in new research.
