LISA is a groundbreaking mission, led by the European Space Agency (ESA) in collaboration with NASA, to develop the largest observatory ever built. It consists of three satellites in a triangular formation, each 2.5 million kilometres apart, and aims to detect gravitational waves. Gravitational waves are formed by extreme cosmic events such as the merger of black holes and create ripples in the fabric of space-time. LISA stands for Laser Interferometer Space Antenna. Each satellite will emit a laser towards the other two and measure tiny changes in the distance between satellites due to gravitational waves. Despite the enormous distance between the satellites (six times the distance from the Earth to the Moon), the sophisticated optical instruments on board can pick up changes smaller than the size of a helium atom and hence detect gravitational waves. The results from the mission will shed light on what happens when black holes collide and provide insight into the origins of the universe, immediately after the Big Bang. Two Galway-based companies, ATG Innovation and EireComposites, will play key roles in the LISA mission. ATG will design the central tube (the chassis of the satellite) based on its patented lightweight, high-stiffness, grid-stiffened structural architecture, and EireComposites will manufacture and assemble the structure. This work will encompass everything from the manufacture of test components and structural assemblies to autoclave curing, bonding, and precision machining. Detailed inspections will be carried out to make sure each part meets strict aerospace standards, using non-destructive testing and dimensional checks throughout the build. By combining advanced computational modelling, hands-on manufacturing, and meticulous quality control, the partners will deliver reliable, high-performance structures that are central to the success of the LISA project. Jacob Pasqualotto, Director of Operations at ATG Engineering, commented, "Leading the Irish contribution to LISA alongside OHB and ÉireComposites is a privilege and a responsibility we embrace with pride. This mission takes gravitational-wave astronomy beyond Earth, extending our reach into the vast low-frequency universe where supermassive black holes and cosmic giants reveal their secrets. For us, this is more than engineering; it is Ireland's signature on the future of astrophysics. Tomas Flanagan, CEO of ÉireComposites, added, "Nearly everything we know about the universe comes from telescopes; LISA provides a completely different approach by focusing on gravitational waves instead of light. It's hard to believe that we'll be making structural carbon-fibre components for the largest machine that humanity has ever built and that we will be seeking evidence to support Einstein's general theory of relativity. The fact that we've been chosen by ESA to partner with ATG for this mission is a huge endorsement of EireComposites, ATG and the Irish Space industry in general."

fWotD Episode 3093: Redshift Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles.The featured article for Thursday, 23 October 2025, is Redshift.In physics, a redshift is an increase in the wavelength, or equivalently, a decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and increase in frequency and energy, is known as a blueshift. The terms derive from the colours red and blue which form the extremes of the visible light spectrum.Three forms of redshift occur in astronomy and cosmology: Doppler redshifts due to the relative motions of radiation sources, gravitational redshift as radiation escapes from gravitational potentials, and cosmological redshifts caused by the universe expanding. In astronomy, the value of a redshift is often denoted by the letter z, corresponding to the fractional change in wavelength (positive for redshifts, negative for blueshifts), and by the wavelength ratio 1 + z (which is greater than 1 for redshifts and less than 1 for blueshifts). Automated astronomical redshift surveys are an important tool for learning about the large scale structure of the universe.Examples of strong redshifting are a gamma ray perceived as an X-ray, or initially visible light perceived as radio waves. The initial 3000K radiation from the Big Bang has redshifted far down to become the 3K cosmic microwave background. Subtler redshifts are seen in the spectroscopic observations of astronomical objects, and are used in terrestrial technologies such as Doppler radar and radar guns. Gravitational waves, which also travel at the speed of light, are subject to the same redshift phenomena.Other physical processes exist that can lead to a shift in the frequency of electromagnetic radiation, including scattering and optical effects; however, the resulting changes are distinguishable from (astronomical) redshift and are not generally referred to as such.This recording reflects the Wikipedia text as of 01:13 UTC on Thursday, 23 October 2025.For the full current version of the article, see Redshift on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Bluesky at @wikioftheday.com.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm generative Danielle.

In this episode of SpaceTime, we delve into the intriguing world of near-Earth asteroids, the evolution of our universe, and the remarkable discovery of a rogue planet experiencing unprecedented growth.Invisible Asteroids Near Venus: A Hidden ThreatRecent computer simulations published in the journal Astronomy and Astrophysics have raised alarms about a population of near-Earth asteroids that remain undetectable due to their proximity to Venus. These Venusian co-orbital asteroids, which share an orbital resonance with Venus, could pose a collision risk to Earth within a few thousand years. The study's lead author, Valerio Carumba, explains the challenges of observing these asteroids, as they are obscured by the Sun's glare. With a size of around 300 metres, these asteroids could create impact craters several kilometres wide, highlighting the need for dedicated space missions to monitor this potential threat.The Universe's Evolution: New Insights from the Epoch of ReionizationAstronomers have made significant strides in understanding the universe's early days, revealing that it was warmer than previously thought before the first stars ignited. Research based on observations from the Murchison Wide Field Array in Western Australia indicates that the gas between galaxies was heated around 800 million years after the Big Bang, contradicting earlier theories of a cold universe. This heating, likely driven by early X-ray sources, set the stage for the epoch of reionization, which transformed the cosmos from opaque to transparent, allowing light to travel freely.A Richie Planet's Remarkable Growth SpurtIn a groundbreaking discovery, astronomers have identified a rogue planet, catalogued as char 11 oh 7 minus 7626, that is not bound to any star and is growing at an astonishing rate of 6 billion tonnes of gas and dust per second. Located approximately 600 light years away in the constellation Chameleon, this planet challenges conventional notions of planetary stability. Observations reveal that its accretion rate fluctuates dramatically, highlighting the dynamic processes at play in the formation of rogue planets and blurring the lines between planets and stars.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstronomy and Astrophysicshttps://www.aanda.org/Astrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Invisible Asteroids Near Venus: A Hidden ThreatThe Universe's Evolution: New Insights from the Epoch of ReionizationA Richie Planet's Remarkable Growth Spurt(00:00) The threat posed by invisible asteroids near Venus(10:30) New findings on the universe's warm early phase(19:00) Discovery of a rogue planet growing at record rates(27:15) Science Robert: 2025 Nobel Prize announcements

The future belongs to organizations that engineer ecosystems with spacecraft-level precision. Carol Erikson reveals the breakthrough: applying aerospace systems engineering to organizational transformation unlocks exponential performance gains across speed, cost, and effectiveness.After 30 years leading aerospace missions and digital transformation at Northrop Grumman, Erikson discovered the paradigm that will define next-generation ecosystems: simultaneous execution of seemingly contradictory strategies. Aerospace-grade systems thinking creates adaptive networks that thrive under pressure, delivering breakthrough results while traditional approaches stagnate.Paradigm Shifts:→ Vision as Gravitational Force: Common vision doesn't just align - it functions as engineered gravity in human systems. Erikson reveals how aerospace teams design a "gravitational pull" that keeps ecosystem components in an orbital relationship, even when individual motivations diverge.→ The Common Good Framework Revolution: Notre Dame researchers are developing the first systematic merger of DARPA's decades-proven AI "Common Test Framework" with ethics and trust mechanisms. This could become the universal operating system for human-AI ecosystem governance.→ Systematic Insensitivity Protocol: Mission-critical ecosystems engineer deliberate "noise immunity" - systematic insensitivity to geopolitical chaos while maintaining collaborative urgency. Organizations that master this protocol gain a significant advantage during periods of fragmentation.→ Big Rocks/Little Rocks Simultaneity: The counter-intuitive discovery that breakthrough transformation requires engineering for massive multi-year "big rock" changes AND rapid "little rock" wins simultaneously - with mathematical precision about which rocks to move when in the system architecture of change itself.Ecosystem Impact:→ Competition as Engineered Energy Source: Erikson reveals how to design "healthy competition" as a system component - transforming competitive dynamics from problem to managed energy that accelerates ecosystem performance→ Interface Checkpoint Architecture: Human-AI collaboration designed with spacecraft-level interface specifications - measurable checkpoints, defined limits, and systematic trust mechanisms rather than hoping for organic adoption→ Duplication-of-Effort Diagnostic: When transformation pilots proliferate in isolation, it signals the need for systematic integration. Organizations can now engineer transformation rather than managing random change initiatives→ The Data-First Cascade Effect: Digital transformation follows aerospace assembly sequences - data quality and infrastructure must precede AI deployment, creating predictable transformation timelines and success metrics Innovation: Applying aerospace systems engineering methodology to organizational transformation - treating culture change, digital infrastructure, and stakeholder alignment as integrated system components with defined interfaces, requirements, and failure modes. First systematic approach to engineering human ecosystems with spacecraft-level reliability. Strategic Application: Any mission-critical ecosystem facing simultaneous pressure for speed, cost reduction, and performance improvement. Particularly powerful for regulated industries, defense contractors, healthcare systems, and infrastructure organizations where failure isn't an option.Strategic Reframe: The most adaptive ecosystems will shift from asking "How do we manage organizational change?" to engineering the question: "What are the mathematical interface specifications for human-system collaboration at ecosystem scale - and how do we systematically design predictable behavioral outcomes using aerospace-level precision rather than hoping for emergent organizational alignment?"The Hidden Revolution: Erikson reveals the birth of "Human Systems Engineering" - a new discipline treating human ecosystems as designable systems with engineered interfaces, quantifiable performance metrics, and predictable behavioral outcomes. Organizations that master this approach don't just transform faster; they engineer a sustainable competitive advantage through systematic human-system integration.Guest: Carol Erikson, Founder & President, Erikson Mission Solutions | Former VP Digital Transformation, Northrop GrummanHost: Marco Annunziata, Co-founder, Annunziata Desai AdvisorsSeries Hosts:Vikram Shyam, Lead Futurist, NASA Glenn Research CenterDyan Finkhousen, Founder & CEO, Shoshin WorksEcosystemic Futures is provided by NASA onvergent Aeronautics Solutions Project in collaboration with Shoshin Works.

Gravitational waves show two black holes merge just how Hawking predicted. Plus, a space mission without a target. And a Space probe without a confirmed budget.In January 2025 the LIGO gravitational wave observatories witnessed two distant black holes spinning into each other. In the ten years of LIGO's operations, that's not a first. But the instruments have been improved to such an extent that this time some very important predictions of General Relativity and out understanding of black holes could be tested. As Birmingham University's Alberto Vecchio says, the elegant simplicity of the mathematics of black holes has passed a test, in particular Stephen Hawking's prediction that the surface area of merging black holes can only be increased.Space craft have met comets before. But because spaceflight takes so long to plan and fund, we've only sent them to comets with human-lifetime orbital periods so far, because we know when they're arriving. ESA wants to meet one we've never seen before, one that has never or seldom been in close to the sun, and never been barbecued and seared by the radiation. Colin Snodgrass of the University of Edinburgh explains the plan to launch and park a comet chaser in space to wait for one of these elusive extraterrestrial objects to come in from the cold.That, says Meg Schwamb of Queen's University Belfast, is going to be much easier in the next few years as the Vera Rubin Telescope begins its ten year survey cataloguing anything in the sky that changes. The type of sky survey it will provide will identify, it is hoped, many candidate first-time comets for the small fleet of spacecraft to intercept.Having a spacecraft ready in position rather than having to launch a new one anytime you want to do some science is a good place to be, one would think.NASA's Juno mission has been delivering science from Jupiter since its launch, and is still functioning and able to deliver more. Yet NASA funds are under considerable threat, and as Scott Bolton tells Roland, at the end of this month Juno could be left slowly spiralling into the gas giant, silently collecting data but with no budget to keep the science going.Presenter: Roland Pease Producer: Alex Mansfield Production Coordinator: Jana Bennett-Holesworth

Win/win!In this episode of SpaceTime, we uncover groundbreaking discoveries in planetary science and solar physics, including the remnants of ancient asteroids on Mars, the recovery of the Mother's Day meteorite, and new insights into solar energetic particles.Asteroid Remnants Found in Martian MantleA new study reveals that fragments from ancient asteroids, which significantly impacted Mars around 4.5 billion years ago, are now trapped within the planet's mantle. Data from NASA's Mars Insight lander has provided unprecedented insights into the Martian interior, showing that these remnants, some up to four kilometres wide, offer a unique glimpse into Mars' geological history. The findings suggest a sluggish evolution of the Martian mantle, contrasting sharply with Earth's dynamic tectonic processes.Mother's Day Meteorite DiscoveryIn an exciting expedition, scientists from Curtin University have successfully recovered a meteorite that lit up the skies over Western Australia on Mother's Day. Using the Desert Fireball Network, researchers pinpointed the meteor's landing site and undertook a challenging journey to retrieve samples. Preliminary analysis indicates that the meteorite is an ordinary chondrite, providing valuable insights into its origins and the solar system's history.Tracing Super Fast Electrons from the SunAstronomers have identified two distinct origins for energetic particles emitted by the Sun, thanks to observations from the European Space Agency's Solar Orbiter mission. The research highlights the difference between solar energetic electrons linked to solar flares and those associated with coronal mass ejections. Understanding these two types of solar energetic particles is crucial for predicting space weather and protecting satellites and astronauts from radiation hazards.www.spacetimewithstuartgary.com✍️ Episode ReferencesNASAhttps://www.nasa.gov/Curtin Universityhttps://www.curtin.edu.au/European Space Agencyhttps://www.esa.int/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.

The Elephant in the Universe: 100-year search for dark matter Author: Govert Schilling Challenging Dogma: MOND and the Exclusion of MACHO Headline: Alternative Gravity, MOND, Contests Dark Matter Theory as MACHOs are Ruled Out Amidst the elusive search for dark matter, alternative theories have emerged. Mordehai Milgrom and his colleagues developed Modified Newtonian Dynamics (MOND), proposing that our understanding of gravity is flawed at galactic scales, thereby explaining rotational curves without needing dark matter. While some like Jeremiah Ostriker dismiss it, others such as Stacy McGaugh acknowledge its surprising success in fitting observational data. Gravitational lensing, as demonstrated by the Bullet Cluster, offers strong evidence for dark matter by showing separate distributions of mass and gas during galaxy collisions, challenging MOND. Meanwhile, another dark matter candidate, Massive Compact Halo Objects (MACHOs)—very massive, compact objects in galactic halos—was extensively searched for in the 1990s using gravitational microlensing. Despite significant effort, these searches yielded no detections, effectively ruling out MACHOs as the primary form of dark matter. 1958

In this episode of SpaceTime, we explore the latest revelations from the cosmos, featuring the intriguing interstellar comet 3I Atlas, a groundbreaking theory about our place in the universe, and the safe return of SpaceX Crew 10.The Enigmatic Comet 3I AtlasAstronomers utilizing NASA's Hubble Space Telescope have captured the sharpest images yet of the interstellar comet 3I Atlas, revealing a solid icy nucleus estimated to measure between 320 meters and 5.6 kilometers in diameter. This comet, traveling at a staggering 209,000 kilometers per hour, is believed to have been journeying through interstellar space for approximately 7 billion years. Observations from multiple telescopes are enhancing our understanding of this ancient visitor, including its size, chemical makeup, and physical properties. With a dust plume and tail reminiscent of solar system comets, 3I Atlas offers a unique glimpse into the history of our galaxy as it approaches the sun.Earth's Position in a Cosmic VoidA new hypothesis suggests that Earth and the Milky Way may reside in a vast cosmic void rather than along a filament of the universe's cosmic web. This idea could help resolve the Hubble tension, a discrepancy in the rate of the universe's expansion. The study, presented at the Royal Astronomical Society's National Astronomy Conference, posits that our galaxy might be near the center of a local void, influencing the observed expansion rate of the universe.

In this episode of SpaceTime, we uncover the latest astronomical marvels and pressing concerns in space science.The Cosmic Horseshoe: A Supermassive DiscoveryAstronomers have potentially identified the most massive supermassive black hole ever discovered, dubbed the Cosmic Horseshoe, which is estimated to be around 36 billion times the mass of our Sun. Located approximately 5 billion light years away, this colossal black hole distorts space-time and creates a stunning Einstein ring effect by gravitationally lensing light from distant galaxies. The measurement of its mass combines gravitational lensing and stellar kinematics, providing a rare glimpse into the formation and evolution of galaxies and their central black holes.Possible New Planet in the Alpha Centauri SystemExciting news emerges from the Alpha Centauri star system, where astronomers may have discovered a new planet orbiting Alpha Centauri A, the closest star system to our own at just 4.25 light years away. Using data from NASA's Webb Space Telescope, researchers suggest this Saturn-sized gas giant could be located in the habitable zone of a sun-like star. While the planet's gaseous nature may not support life, its proximity offers a unique opportunity to study planetary systems beyond our own, challenging existing theories on planet formation in binary star systems.The Satellite Proliferation DilemmaAs the number of satellites in Earth orbit continues to rise, astronomers are sounding alarms over the interference these satellites cause to vital scientific research. A study has highlighted the impact of Starlink's megaconstellation on radio astronomy, with significant radio emissions masking faint signals from the universe. This growing concern emphasizes the need for regulatory measures to mitigate interference and protect the integrity of astronomical observations.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical Societyhttps://academic.oup.com/mnrasAstrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Astronomy and Astrophysics Journalhttps://www.aanda.org/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.
