Look no further than the missions racing to unlock dark matter and the mysterious force known as dark energy, both so named precisely because science has yet to explain these phenomena.

Astronomers have never detected dark matter, but they believe it makes up about 85% of the total matter in the universe. Meanwhile, the existence of dark energy helps researchers explain why the universe is expanding — and why that expansion is speeding up.
Extraordinary new scientific instruments are churning out trailblazing data, ready to reshape how scientists view the cosmos.

A prime example is the European Space Agency’s wide-angle Euclid telescope that launched in 2023 to investigate the riddles of dark energy and dark matter.

Euclid this week delivered the first piece of a cosmic map — containing about 100 million stars and galaxies — that will take six years to create.

These stunning 3D observations may help scientists see how dark matter warps light and curves space across galaxies.

Meanwhile, on a mountaintop in northern Chile, the US National Science Foundation and Stanford University researchers are preparing to power up the world’s largest digital camera inside the Vera C. Rubin Observatory.

Unearthed
In the mountains of Uzbekistan, a research team used lasers strapped to a flying robot to uncover two cities buried and lost for centuries.

The anthropologists said they had mapped these forgotten medieval towns for the first time — located at a key crossroad of ancient silk trade routes — using a drone equipped with LiDAR, or light detection and ranging equipment.

When nature reclaims what’s left of once thriving civilizations, scientists are increasingly turning to remote sensing to peer through dense vegetation.

The images revealed two large settlements dotted with watchtowers, fortresses, complex buildings, plazas and pathways that tens of thousands of people may have called home.

Europe’s secret season for travel starts now
Площадка кракен

Summer might be the most popular season for tourism to Europe, but it hardly promises a calm, cool and collected experience.

Who can forget this summer’s protests against overtourism in Barcelona and Mallorca, the wildfires that raged across Greece during the country’s hottest June and July on record and selfie stoplights to help control crowds on the clogged streets of Rome and Florence?

For travelers looking to avoid all that — as well as break less of a sweat literally and financially — welcome to Europe’s secret season.

From roughly mid-October to mid-December, shoulder season for travel to Europe comes with fewer crowds, far more comfortable temperatures in places that skew scorching hot during the summer months and plunging prices on airfare and accommodation.

Plunging prices
“The cheapest time to fly to Europe is typically from about the middle point of October to the middle point of December,” said Hayley Berg, lead economist at travel platform Hopper. “Airfare prices during those eight or nine weeks or so will typically be about an average of 40% lower than prices in the peak of summer in June.”

Hopper’s data shows that airfare to Europe from the United States during the period between October 20 and December 8 is averaging between $560 and $630 per ticket — down 9% from this time last year and 5% compared to the same timeframe in 2019.

Balanset-1A: El Instrumento Perfecto para la Balanceo de Rotores



La balanceo de rotores es un proceso crucial en la industria, ya que garantiza el funcionamiento eficiente de diversas máquinas. El Balanset-1A es un dispositivo innovador que permite realizar esta tarea con precisión, mejorando la vida útil de los equipos y reduciendo costes de mantenimiento. En este artículo, exploraremos las características de este instrumento y el proceso de balanceo de rotores en una y dos platas.



¿Qué es el Balanset-1A?



El Balanset-1A es un equipo diseñado para equilibrar rotores en una o dos planos, adaptándose a las características constructivas de la máquina en cuestión. Este dispositivo es ideal para una variedad de aplicaciones industriales, incluyendo motores eléctricos, generadores, y compresores.



Tipos de Balanceo



El proceso de balanceo puede realizarse en una o dos planos:





Balanceo en una planca (estático): Este método se utiliza para rotores delgados y discoidales que no presentan un desbalance axial significativo. Ejemplos típicos incluyen discos de rectificado, poleas y acoplamientos.

Balanceo en dos planos (dinámico): Este es el método preferido para rotores largos y de doble apoyo, como los rotores de motores eléctricos, bombas y turbinas.





Componentes del Balanset-1A



El Balanset-1A viene equipado con:





2 vibrómetros

1 sensor de ángulo de fase (taquímetro láser)

1 unidad de medición (Balanset)

1 soporte magnético

1 balanza electrónica

1 maletín para transporte

Software en un pen drive





El precio del Balanset-1A es de 1751 euros.



Proceso de Balanceo con Balanset-1A



El proceso de balanceo de un rotor con el Balanset-1A incluye varias etapas clave:



1. Preparación del Equipo

Coloque los sensores de vibración perpendicularmente al eje de rotación del rotor. Fije el taquímetro láser en el soporte magnético, alineándolo con la cinta reflectante adherida a la polea. Conecte los sensores al dispositivo y vincule este último a un ordenador a través de USB. Inicie el software Balanset, seleccionando el modo de balanceo en dos planos.



2. Medición Inicial de Vibraciones

Pesé el peso de prueba y registre su peso y radio de instalación. Haga girar el rotor y mida el nivel de vibración inicial para determinar la amplitud y fase del desbalance inicial.





3. Balanceo en la Primera Placa

Instale el peso de prueba en la primera placa de balanceo, correspondiente a la ubicación del primer sensor. Haga girar el rotor y mida el nivel de vibración. Es importante que la amplitud o fase cambien al menos un 20%, lo que indica que el desbalance se ha corregido parcialmente.





4. Balanceo en la Segunda Placa

Traslade el peso de prueba a la segunda placa (donde se encuentra el segundo sensor), vuelva a encender el rotor y realice otra medición. Estos datos ayudarán al software a calcular la ubicación y el peso exactos de los pesos correctores.





5. Corrección del Desbalance

Basándose en los datos obtenidos, el programa Balanset sugerirá los pesos correctores y los ángulos de instalación para ambas placas. Retire el peso de prueba y prepare los pesos correctores según las recomendaciones del programa. Colóquelos en el ángulo adecuado en la dirección de rotación del rotor desde la posición inicial del peso de prueba.







6. Verificación y Finalización del Balanceo

Haga girar el rotor para una verificación final del balanceo. Si la vibración ha disminuido a un nivel aceptable, el proceso está completo. En caso de necesitar correcciones adicionales, el software indicará dónde y cuánto peso más debe instalarse.



Conclusión



El Balanset-1A se presenta como una solución eficiente y precisa para la balanceo de rotores, fundamental para el mantenimiento adecuado de maquinaria industrial. Con su capacidad de operar en una y dos planos, este dispositivo se adapta a las necesidades de diferentes industrias, asegurando un rendimiento óptimo y prolongando la vida útil de los equipos.

‘We barely made it out’: Californians desperately flee their homes amid raging wildfires
омг вход
Terrie Morin, 60, and her husband, Dave, were at the barber shop when they heard about a raging wildfire making headway toward their Camarillo home on Wednesday morning.

The couple were hosting two guests at the time, but because their guests worked late, Morin suspected they slept through the residence’s fire alarms.

“I run in the house, and I’m banging on the door, and they did not hear me. They were knocked out,” Morin told CNN. “Get the dog. Get out of here. You don’t have time, just get out!” she recalled telling them.

Ten minutes later, Dave noticed sparks in their backyard. The temperature was also picking up.

“It was hot. It was so hot,” Morin recalled.

Dozens of homes in California’s Ventura County were set alight in a sweeping wildfire that burned through thousands of acres of land in just a matter of hours midweek –– prompting authorities to send more than 14,000 evacuation notices across the region.

The Mountain Fire began early Wednesday and was driven by winds gusting over 60 mph. The flames have seared through more than 20,485 acres of land, according to Cal Fire.

The families who evacuated at a moment’s notice, some who say they have now lost their homes, must deal with other losses that can also be devastating, from daily essentials like medications and shoes to meaningful possessions such as sculptures and artwork, to treasured keepsakes from the birth of a child or the life of a parent.

At least 132 properties have been destroyed by the fire, while 88 have been left damaged, Ventura County Fire Department officials said Thursday evening. Ten damage inspection teams have been deployed to inspect structures along the path of the blaze.

Ten people endured non-life-threatening injuries from the Mountain Fire, which are mostly related to smoke inhalation, Ventura County Sheriff Jim Fryhoff said.

Family hasn’t heard from Hawaii woman in over a week after she misses flight to New York
kra17 cc

It’s been more than a week since Hannah Kobayashi missed a flight connection in Los Angeles. After a series of suspicious texts from her phone, the 30-year-old Hawaii woman has gone silent – and her family is desperately trying to find her.

Kobayashi was traveling from Maui, Hawaii, to New York and had a connecting flight at Los Angeles International Airport, her sister, Sydni, told CNN by phone Monday. She had the same itinerary as an ex-boyfriend; the pair decided to keep their flights since they couldn’t get a refund but would be going their separate ways once they landed at John F. Kennedy International Airport.

Hannah was going to spend time in upstate New York with her aunt, Sydni said. But November 11 was the last day anyone heard from her.

Sydni said text messages from Hannah in the lead-up to her disappearance did not sound like her. Hannah used words like “hun,” “love” and “babe.”

“I personally don’t think that was my sister,” Sydni said. “She doesn’t use the word ‘hun.’ ‘Love’ and ‘babe,’ but never ‘hun.’ Even her close friends have said the same.”

Sydni added, “The reason why it’s so concerning is because we’re so close and I’ve known her to always be very grounded and she’s always had a calm and collected demeanor. Yes, she’s a free and independent spirit and she likes to travel, she’s a writer and photographer, but she’s never done anything like this on purpose.”
