China está construyendo una planta de energía solar en el espacio

China está construyendo una planta de energía solar en el espacio
China es un país ambicioso cuando se trata de proyectos tecnológicos y espaciales. Pero el más reciente rumor en torno a ellos y una planta de energía solar espacial parece materia de ciencia ficción. De acuerdo con reportes del The Sydney Morning Herald y Futurism, la Academia de Tecnología Espacial de China estaría trabajando actualmente en el desarrollo de una planta de energía solar orbital. La cuál capturaría la energía del sol allá arriba en el espacio para luego enviarla a la Tierra...

Dormir puede ser más eficaz que una medicina: mejora el sistema inmunológico

Dormir puede ser más eficaz que una medicina: mejora el sistema inmunológico
El sueño mejora la capacidad potencial de algunas de las células inmunitarias del cuerpo, según un nuevo estudio publicado en Journal of Experimental Medicine. El estudio, dirigido por Stoyan Dimitrov y Luciana Besedovsky en la Universidad de Tübingen, en Alemania, ayuda a explicar cómo el sueño puede combatir una infección, mientras que otras condiciones, como el estrés crónico, pueden hacer que el cuerpo sea más susceptible a las enfermedades...

Probablemente, a más de 600 km de profundidad existen montañas más altas de media de las que hay en la superficie de la Tierra
Las capas profundas de la Tierra son tan complicadas como lo que observamos en la superficie. También son mucho más ignotas: solo hemos logrado hacer excavaciones de 11 kilómetros de profundidad, como máximo, y el resto de información que tenemos de las entrañas de nuestro planeta se basan en mediciones indirectas y suposiciones. Una de las más novedosas sugiere que bajo la superficie de la Tierra podrían haber montañas incluso más elevadas que las que encontramos en la superficie, es decir, cambios de elevación de 1-3 kilómetros en un límite que tiene más de 660 kilómetros de profundidad...

SpaceX files protest of NASA’s Lucy launch contract awarded to ULA

SpaceX files protest of NASA’s Lucy launch contract awarded to ULA
SpaceX has filed a protest challenging a nearly $150 million NASA contract awarded to United Launch Alliance last month to send a robotic asteroid probe into space. The protest submitted to the Government Accountability Office on Feb. 11 questions a launch contract for NASA’s Lucy science mission to United Launch Alliance. NASA announced Jan. 31 that ULA won the launch contract for the Lucy mission, set for liftoff in October 2021 from Cape Canaveral aboard ULA’s Atlas 5 rocket...

A river of stars in the solar neighborhood

A river of stars in the solar neighborhood
Night sky centered on the south Galactic pole in a so-called stereographic projection. In this special projection, the Milky Way curves around the entire image in an arc. The stars in the stream are displayed in red and cover almost the entire southern Galactic hemisphere, thereby crossing many well-known constellations...

A river of stars in the solar neighborhood
Astronomy & Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago. Due to its proximity to Earth, this stream is a perfect workbench on which to test the disruption ...

An Asteroid Will Block Our Brightest Star on Monday, And Astronomers Need Your Help

An Asteroid Will Block Our Brightest Star on Monday, And Astronomers Need Your Help
Sirius, a double-star system and the brightest object in the night sky, will briefly blink out of existence for parts of Earth on Monday evening. In an event called an occultation – when one object in space blocks the light of another behind it – a small asteroid known as (4388) Jürgenstock will slip in front of the star for a fraction of a second and, like an eclipse, cause it to briefly dim or even disappear...

“Neutron Sirens” –Will Solve ‘Hubble’s Conundrum’ About Our [ NOT ] Expanding Universe
“The Hubble Constant is one of the most important numbers in cosmology because it is essential for estimating the curvature of space and the age of the universe, as well as exploring its fate,” said Hiranya Peiris, at University College London [ BUT THE ASSUMPTIONS OF ASTRONOMERS ARE ALL WRONG: THE BIG BANG DIDN'T EXISTS ]. Peiris, a British astrophysicist best known for her work on the cosmic microwave background radiation, was one of 27 scientists who received the Breakthrough Prize in Fundamental Physics in 2018 for their “detailed maps of the early universe.”...

New Map of Dark Matter Spanning 10 Million Galaxies Hints at a Flaw in Our Physics

New Map of Dark Matter Spanning 10 Million Galaxies Hints at a Flaw in Our Physics
An invisible force is having an effect on our Universe. We can't see it, and we can't detect it - but we can observe how it interacts gravitationally with the things we can see and detect, such as light. Now an international team of astronomers has used one of the world's most powerful telescopes to analyze that effect across 10 million galaxies in the context of Einstein's general relativity. The result? The most comprehensive map of dark matter across the history of the Universe to date...

Western Digital’s RISC-V “SweRV” Core Design Released For Free

Western Digital’s RISC-V "SweRV" Core Design Released For Free
Western Digital has published a register-transfer level (RTL) design abstraction of its in-house designed SweRV RISC-V core. The SweRV core is one of several RISC-V projects the company as undertaken as part of their effort to spearhead the ISA, its ecosystem, and foster their own transition away from licensed, royalty-charging CPU cores. In accordance with the more open design goals of RISC-V, the publication of the high-level representation of SweTV means that third parties can use it in their own chip designs, which will popularize not only the particular core design, but also the RISC-V architecture in general...
