Mysterious Space Plane X-37B to Try ‘First of a Kind’ Maneuvers in Orbit

Posted by in category: space

The X-37B Orbital Test Vehicle (OTV) has been shrouded in mystery since its maiden flight in 2011.

Designed by Boeing and operated by the US Space Force (USSF), this remotely operated, reusable space plane is designed to operate in Low-Earth Orbit (LEO), 240 to 800 kilometers (150 to 500 miles) above the Earth, and test reusable vehicle technologies that support long-term space objectives.

On December 29th, 2023, the X-37B began its seventh mission (OTV-7) and has reportedly been conducting experiments on the effects of space radiation and testing Space Domain Awareness (SDA) technologies.

Google Pivots to Nuclear Reactors to Power Its Artificial Intelligence

Posted by in categories: climatology, nuclear energy, robotics/AI

Google on Monday signed a deal to get electricity from small nuclear reactors to help power artificial intelligence.

The agreement to buy energy from reactors built by Kairos Power came just weeks after word that Three Mile Island, the site of America’s worst nuclear accident, will restart operations to provide energy to Microsoft.

“We believe that nuclear energy has a critical role to play in supporting our clean growth and helping to deliver on the progress of AI,” Google senior director of energy and climate said during a briefing.

From $8,000 to $3: OpenAI’s Revolutionary Impact on Legal Work

Posted by in categories: law, robotics/AI

OpenAI CPO Kevin Weil says their o1 model can now write legal briefs that previously were the domain of $1000/hour associates: “what does it mean when you can suddenly do $8000 of work in 5 minutes for $3 of API credits?” pic.twitter.com/MotT9Oo9rv

ESA: First piece of great cosmic map features 100 mn celestial objects

Posted by in category: cosmology

The universe’s structure spans a vast network 500 times the size of the moon.


According to ESA, “This first piece of the map already contains around 100 million sources: stars in our Milky Way and galaxies beyond. Some 14 million of these galaxies could be used to study the hidden influence of dark matter and dark energy on the Universe.”

Scientists Have Mapped 1 Million New Galaxies In Just 300 Hours

Posted by in category: space

Australian scientists say they have mapped a million new galaxies using an advanced telescope in the desert.

Astronomers mapped 83% of the sky and discovered 1 million new galaxies in just 300 hours.

The CSIRO, the national science agency, said its new telescope had created “a new atlas of the Universe” in record time – showing unprecedented detail.

The Rapid ASKAP Continuum Survey I: Design and first results

Posted by in categories: futurism, space

The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope. RACS will provide a shallow model of the ASKAP sky that will aid the calibration of future deep ASKAP surveys. RACS will cover the whole sky visible from the ASKAP site in Western Australia and will cover the full ASKAP band of 700‑1800 MHz. The RACS images are generally deeper than the existing NRAO VLA Sky Survey and Sydney University Molonglo Sky Survey radio surveys and have better spatial resolution. All RACS survey products will be public, including radio images (with $\sim$15 arcsec resolution) and catalogues of about three million source components with spectral index and polarisation information. In this paper, we present a description of the RACS survey and the first data release of 903 images covering the sky south of declination $+41^\circ$ made over a 288-MHz band centred at 887.5 MHz.

Light From Behind A Black Hole Observed For The First Time, Confirming Einstein’s Theory

Posted by in categories: cosmology, physics

All our science, measured against reality, is primitive and childlike – and yet it is the most precious thing we have. – Albert Einstein (1879−1955)

Astronomers have observed light bending around a black hole, a phenomenon predicted by Einstein’s theory of general relativity. By studying X-rays from a black hole in the Zwicky 1 galaxy, scientists detected unexpected “light echoes” coming from behind the black hole, proving that the black hole’s gravity was curving space-time and allowing light to bend around it.

Although this effect was predicted over a century ago, it’s the first time astronomers have witnessed it. The researchers now aim to investigate how black hole coronas produce intense X-ray flares and continue studying space-time distortion.

Astronomers Witness A Star Dragging Space-Time Around With It

Posted by in categories: physics, space

A spinning white dwarf drags space-time around it 100 million times more powerfully than Earth.

Astronomers have recently provided compelling evidence of a star dragging space-time, showcasing one of Einstein’s lesser-known predictions. This phenomenon, known as “frame-dragging,” describes how a spinning object distorts the very fabric of space-time around it. While this effect is nearly imperceptible in everyday life, even on a planetary scale, certain cosmic conditions make it much more noticeable. A study published in Science details these observations using a radio telescope to study a rare pair of compact stars.

NASA Shuts Down Quantum Computer After Unexpected Results

Posted by in categories: computing, quantum physics, space travel

NASA has temporarily halted operations of its quantum computer after it produced unexpected results. The computer, which is still under development, is designed to simulate complex systems such as those found in space. However, during a recent test, the computer-generated results that were inconsistent with known physical laws.

NASA scientists are currently investigating the cause of the anomaly. They are also working to develop safeguards to prevent similar incidents from happening in the future.

The shutdown of the quantum computer is a setback for NASA’s efforts to develop new technologies for space exploration. However, it is also an opportunity to learn more about the potential of quantum computing.
