Solsystemet: solen og planeterne

Der sker hele tiden noget nyt og spændende inden for rumforskningen. I 2022 lykkedes det forskerholdet Event Horizon Telescope Collaboration at optage et billede af det sorte hul i Mælkevejen. James Webb Teleskopet leverer billeder af galakser, der ligger 13 milliarder lysår borte. De opdagelser, som den danske forsker Albert Sneppen har gjort omkring neutronstjerners sammenstød, kan måske bruges til at beregne universets udvidelseshastighed. I ”Det gådefulde univers” giver Danmarks mest anerkendte astrofysiker et overblik over himmelrummet fra Solsystemet og ud til de fjerneste galakser og over universets udvikling fra Big Bang frem til i dag.Universet blev skabt for 13,7 milliarder år siden. Et lysår er ca. 9,5 billioner kilometer, og afstanden til de fjerne kvasarer er 12 milliarder lysår. Når man beskæftiger sig med universet, handler det om svimlende tidshorisonter og afstande; men Anja C. Andersen formår at gøre det uoverskuelige begribeligt. Stor gavebog med fantastisk billedmateriale.

Teorien om Big Bang er den bedste model, vi i øjeblikket har om universets skabelse; men det betyder ikke, at det er den endelige sandhed. Men hvorfor er der stort set enighed om, at universet for 13,7 milliarder år siden blev skabt af en tætpakket klump, der rummede al energi og alt stof? Og eksisterede der noget inden Big Bang? Astrofysikeren Anja C. Andersen formidler teorier og forskningsresultater udogmatisk og letforståeligt.

Der er ikke otte, men milliarder af planeter i Universet, og mange af dem ligger i et lunt smørhul, hvor de potentielt kan huse liv. Den opdagelse er en af de største i den moderne astronomi, og vi er kun lige begyndt at forstå, hvad der egentlig gemmer sig derude i kosmos af bizarre kloder. 'Fjerne kloder' beskriver erkendelsesrejsen, fra Giordano Bruno blev brændt på bålet i år 1600 for sin kætterske idé om uendelig mange planeter – og til konstruktionen af små satellitter, som måske kan besøge de nærmeste af disse exoplaneter og lede efter livstegn på dem. Undervejs møder vi forskerne ved fronten, som kigger hinsides solsystemet og kæmper for at besvare det ultimative spørgsmål: Er vi alene?

Vi vover at forestille os en tid før Big Bang, hvor hele universet var presset sammen til et område mindre end et atom. Og nu kan vi, som Brian Cox og Jeff Forshaw viser, gøre mere end blot at forestille os: Vi kan forstå. Gennem århundreder har den menneskelige trang til at opdage afdækket en utrolig mængde viden. Hvad den afslører for os, gør os åndeløse.UNIVERSEL tager os med på en storslået videnskabelig opdagelsesrejse og afslører undervejs, hvordan vi kan forstå nogle af de mest grundlæggende spørgsmål omkring vores Jord, Sol og solsystem og de stjernefyldte galakser længere væk. Nogle af disse spørgsmål – hvor stort er vores solsystem? Hvor hurtigt udvider rummet sig? - kan besvares fra vores baghave; svarene på andre – hvor stort er universet? Hvad er det lavet af? - trækker på forbløffende informationer, som netop nu indsamles af hold af astronomer, der arbejder i grænselandet af det kendte univers.I centrum af alle disse spørgsmål – fra de tidligste forsøg på at måle tyngdekraften til vores bestræbelser på at forstå, hvad mørkt stof er, og hvad der virkelig skete ved universets fødsel – står den videnskabelige proces. Videnskaben afslører en dybere skønhed, forbinder os med hinanden, med vores verden og med vores univers, og rækker ved at forstå andres banebrydende arbejde ind i det ukendte. Ydermere viser UNIVERSEL os, at hvis vi tør bruge vores forestillingsevne, kan vi alle gøre det.

Hvorfor er vores univers, som det er? Hvordan begyndte alting? Hvordan vil det ende? Fysikeren Thomas Hertog granskede disse store spørgsmål sammen med Stephen Hawking og fik derved et helt særligt kendskab til de forbløffende indsigter, som Hawking, trods enorme fysiske udfordringer, arbejdede med sent i livet. Denne yderst velskrevne bog af Hawkings tætteste samarbejdspartner gennem 20 år giver et unikt indblik i et ekstraordinært menneske, hvordan kreative processer fungerer, samt omfanget og begrænsningerne af vores nuværende forståelse af kosmos. Tidens oprindelse er en tankevækkende beretning om videnskaben og de personligheder, der medvirkede i Stephen Hawkings ihærdige forsøg på at forstå kosmos.

Every night, above our heads, a drama of epic proportions is playing out. Diamond planets, zombie stars, black holes heavier than a billion Suns. The cast of characters is extraordinary, and each one has its own incredible story to tell.

Mennesket har altid været optaget af Mars. Planeten kan som én af de eneste ses med det blotte øje fra Jorden, og helt fra Galileis opfindelse af teleskopet i 1600-tallet og frem til nu er det blevet debatteret, om der er eller har været liv på Mars.Mars er afbildet på 70.000 år gamle hulemalerier i Botswana og fascinerer stadig den dag i dag, hvor 600.000 danskere i 2021 fulgte med i live-sendingen af roveren Perseverances landing på Mars.I den rigt illustrerede bog gennemgår Tina Ibsen myterne om den røde planet, Mars-forskningens historie, de unikke geologiske og atmosfæriske forhold på planeten, vores missioner til Mars og den imponerende teknologi, der ligger bag opsendelserne af rumsonder og rovere - og ikke mindst det store spørgsmål: Er der liv på Mars - og kan mennesket bo der engang i fremtiden?I bogen er der interview med tre danske forskere:Morten Bo Madsen, der er lektor på Niels Bohr Instituttet og har deltaget i seks af NASAs Mars-missioner.Jens Frydenvang, der er adjunkt ved Globe Institute på Københavns Universitet og deltager i både Perseverance- og Curiosity-missionerne.Line Drube, der er ph.d. i astrofysik fra Niels Bohr Institutet og har deltaget i Phoenix-Marsmissionen, hvor hun styrede landerens robot-arms kamera fra NASAs kontrolcenter i Tucson."Mars - myter, magi og missioner" er skrevet af astrofysiker Tina Ibsen, kendt fra den populære podcast Rumsnak.

New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it aboutA Penguin ClassicIn the late fifteenth century, the earth stood motionless at the center of a small, ordered cosmos. Around us, it was believed, the moon, the sun, and the planets revolved in crystalline spheres, their orbits perfect, eternally unchanging circles. Just over a century later, the sun was now the center of creation; the earth just another planet hurtling through empty, near-infinite space. This is the story of an astonishing change, a transformation in human thought, about both the universe and our place within it, told through the words of the astronomers and mathematicians at its heart. Encompassing the most evocative excerpts from the works and letters of Copernicus, Galileo, Kepler, Descartes, Newton, and others, and including guiding notes from renowned historian of science, Aviva Rothman, The Dawn of Modern Cosmology is the definitive record of one of science's greatest achievements.

Terraforming af Mars – Science eller fictionTerraforming er et kontroversielt begreb, fordi det synes uden for de tekniske muligheder i dag. Men der er tradition for at overveje og udregne mulighederne inden for den verden, som både Dansk Selskab for Rumfartsforskning og British Interplanetary Society er vokset ud af.Dansk Selskab blev grundlagt i 1949 – otte år før den første kunstige satellit Sputnik. Den gang var rumfart noget forholdsvis hypotetisk baseret på udregninger ud fra fysikkens love. Det samme kan man sige om terraforming i dag. Men hvordan ser det så ud? Bogen gennemgår en række problemstillinger i den forbindelse.

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe. At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes.Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole ? heating it to millions of degrees as it is shredded at the event horizon.They have the power to wipe out any of the universe's other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole ? a link through space and time. It seems outlandish, but today's physicists are daring to think the unthinkable ? that black holes could connect us to another universe.At their very heart, black holes are also where Einstein's Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes.Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered.

Gas monsters, otherwise called gas goliath planets, are enormous planets fundamentally made out of hydrogen and helium, with hints of different gases and unpredictable mixtures. These enormous divine bodies, like Jupiter and Saturn in our nearby planet group, have one of a kind qualities that make them charming subjects for energy investigation. While the essential focal point of current space investigation is on understanding these far off planets, the idea of outfitting energy from gas monsters remains generally speculative and hypothetical. The tremendous gravitational powers and environmental states of gas goliaths present huge difficulties to any potential energy investigation attempts. Jupiter, for instance, is a goliath planet with a measurement of around 86,881 miles, and its climate is made predominantly out of hydrogen and helium. The extreme strain and tempestuous atmospheric conditions, including strong tempests like the Incomparable Red Spot, present impressive impediments for space apparatus and tests. One speculative thought for gas monster energy investigation includes taking advantage of the immense measures of hydrogen present in their airs. Hydrogen, in its sub-atomic structure, is a possible wellspring of clean energy through processes like combination. Combination responses, like those happening in the center of stars, discharge gigantic measures of energy. While current innovation faces various difficulties in tackling combination for viable use on The planet, the idea of extricating hydrogen from gas goliaths and using it for energy creation stays an entrancing idea for the far off future. One more charming part of gas goliath investigation is the potential for using their moons as stages for energy-related exercises. For example, certain moons of gas monsters, like Europa and Titan, have caught the interest of researchers because of the chance of subsurface seas and extraordinary air conditions. These moons might offer assets like water ice and hydrocarbons, which could be utilized for different energy applications. The possibility of gas monster energy investigation is at present inside the domain of logical hypothesis and advanced ideas. Trend setting innovations and forward leaps in space investigation would be important to conquer the considerable difficulties introduced by the outrageous states of gas monsters. As how we might interpret these far off planets extends and our mechanical capacities advance, the fantasy about taking advantage of the energy assets of gas monsters might turn into a reality, adding to the development of humankind's venture into the universe.

The gas world, an extensive domain of undetectable components and mixtures, holds ponders that shape the actual texture of our reality. From the life-supporting oxygen we inhale to the air gases that oversee weather conditions, the gas world is a quiet orchestrator of normal peculiarities and a vital participant in the unpredictable equilibrium of Earth's biological systems. At the core of the marvels of the gas world is the air we inhale, a powerful mix of gases fundamental forever. Nitrogen, involving most of Earth's air, gives the latent setting to the oxygen that supports high-impact living things. Oxygen itself, delivered through the course of photosynthesis by plants and green growth, fills the cell cycles of creatures and people, framing the foundation of breath. The ozone depleting substances, including carbon dioxide, methane, and water fume, add to the sensitive guideline of Earth's temperature. Behaving like a characteristic cover, these gases trap heat from the sun, keeping it from getting away from once more into space. This nursery impact keeps a tenable environment, considering the different biological systems that describe our planet. Nonetheless, human exercises, like the consuming of petroleum products, have prompted an expansion in ozone harming substance fixations, adding to environmental change and adjusting the fragile equilibrium of the gas world. Past the bounds of Earth, the gas world reaches out into the endlessness of room. Clouds, made out of ionized gases, act as heavenly nurseries, bringing forth new stars and planetary frameworks. The interstellar medium, a diffuse breadth of gas and residue, shapes the infinite scene and impacts the development and development of universes. In the domain of industry and innovation, gases display striking properties that fuel advancement and progress. Hydrogen, a flexible gas, powers energy components and holds guarantee as a spotless energy transporter. Respectable gases, like helium, track down applications in cryogenics, cooling advancements, and, surprisingly, as fundamental components in clinical diagnostics. The gas world additionally holds secrets yet to be completely unwound. Exoplanetary environments, made out of a bunch of gases, offer hints about the expected tenability of far off universes. The investigation of dull matter, a baffling part of the universe, includes grasping its connections with normal matter, including gases, to understand the grandiose powers at play. In synopsis, the marvels of the gas world are both earthly and astronomical, molding the circumstances that help life on The planet and impacting the elements of the universe. From the imperceptible breath of life to the infinite artful dance of heavenly gases, the gas world enraptures researchers, stargazers, and travelers the same, welcoming us to wonder about its intricacy and embrace the significant effect it has on the excellent embroidered artwork of presence.

The book presents a broad and in-depth overview of recent achievements and the current state of research in magnetohydrodynamic (MHD) oscillatory and wave phenomena in the coronae of the Sun and stars. Major progress in coronal wave studies has been achieved thanks to the combination of high-precision multi-wavelength observations with spaceborne and ground-based facilities, elaborated theory of the interaction of MHD waves with plasma non-uniformities, state-of-the-art numerical simulations, and novel data analysis techniques. It has allowed the research community to reach a new look at the role played by MHD wave processes in the enigmatic phenomena of coronal plasma heating and wind acceleration as well as powerful energy releases such as flares and coronal mass ejections. In addition, the waves are intensively used as natural probes in the remote diagnostics of the coronal plasma parameters and physical processes operating in solar and stellar coronae via the method of MHD seismology. Individual chapters cover recent cutting-edge results obtained on the analysis and theoretical modelling of several most intensively studied coronal MHD wave phenomena, namely, kink and sausage oscillations of coronal loops and other field-aligned plasma structures, plus running and standing slow magnetoacoustic waves. A dedicated chapter assesses the reliability of proposed theoretical mechanisms for heating of the coronal plasma by MHD waves. Another chapter summarizes the current state of our understanding of the physical mechanisms and observational properties of quasi-periodic pulsations in solar flares, considers their analogy with similar processes detected in stellar flares, and thus establishes solid ground for the further exploitation of the solar-stellar analogy. An important discussion of novel data analysis techniques designed recently for MHD seismology applications is presented in a devoted chapter. The direction of future advances in the designated research areas are discussed.The book is a spin-off from the Topical Collection "Oscillatory Processes in Solar and Stellar Coronae" of the journal Space Science Reviews.

The main theme of the book is the presentation of techniques used to identify chaotic behavior in the evolution of conservative mechanical systems and their application to astronomical systems.

In today's rapidly changing world, the importance of renewable energy, particularly solar energy, cannot be overstated. As concerns about climate change, air pollution, and dwindling fossil fuel reserves continue to grow, the adoption of renewable energy sources has become a global imperative. This subchapter aims to shed light on the significance of renewable energy, with a particular focus on solar power, as a solution for powering commercial buildings.First and foremost, renewable energy is clean and sustainable. Unlike traditional sources such as coal and oil, solar energy produces no greenhouse gas emissions or harmful pollutants when converted into electricity. By harnessing the power of the sun, commercial buildings can significantly reduce their carbon footprint, contributing to a healthier and more sustainable environment for everyone. Moreover, solar energy is an abundant resource that will never run out, ensuring a long-term and reliable energy supply.From an economic perspective, the adoption of solar energy can bring substantial benefits. Commercial buildings that utilize solar power can drastically reduce their dependence on expensive fossil fuels, resulting in significant cost savings over time. As the cost of solar technology continues to decline, the return on investment for solar installations has become even more appealing. Moreover, solar energy systems require minimal maintenance, offering long-term financial stability and predictability in energy costs for commercial building owners.Furthermore, solar energy promotes energy independence and resilience. By generating electricity on-site, commercial buildings can become less reliant on the grid, reducing the risk of power outages and disruptions. This is particularly crucial during times of natural disasters or emergencies, when reliable access to electricity is vital.The importance of renewable energy, specifically solar power, extends beyond environmental and economic considerations. It also presents an opportunity to foster innovation and create jobs. The growing demand for solar installations has led to the emergence of a thriving industry, creating employment opportunities and driving economic growth. By investing in solar energy solutions for commercial buildings, we can stimulate technological advancements and contribute to a more sustainable and prosperous future.

The Importance of Environmental JusticeIn recent years, the concept of environmental justice has gained significant attention worldwide. It refers to the fair distribution of environmental benefits and burdens among all members of society, regardless of their race, ethnicity, or socio-economic background. As students, it is essential for us to understand the significance of environmental justice in order to build a sustainable future for our planet.Environmental justice is crucial because it directly affects our well-being and the health of our ecosystems. It addresses issues such as pollution, climate change, and the depletion of natural resources, which have severe consequences for both humans and nature. By promoting environmental justice, we ensure that everyone has an equal opportunity to live in a clean and healthy environment.One of the key reasons why environmental justice is essential is its impact on public health. Many communities, especially those marginalized and economically disadvantaged, are disproportionately exposed to harmful pollutants and contaminants. This unequal distribution of environmental hazards leads to higher rates of respiratory diseases, cancer, and other health problems. By advocating for environmental justice, we can work towards reducing these disparities and improving the overall well-being of all individuals.Furthermore, environmental justice is closely linked to social justice. The communities most affected by environmental degradation are often those with the least political power and resources to fight against it. By addressing environmental injustices, we can also address underlying social inequalities and work towards a more equitable society.By studying environmental justice, students can gain a deeper understanding of the complex and interconnected nature of environmental issues. We can learn about the historical and social factors that contribute to environmental injustices, and how we can take action to mitigate them. This knowledge empowers us to become informed advocates and environmental stewards, capable of creating positive change in our communities.
