Der er kommet masser af ny viden ud af Planck-missionen, som nu er fordelt på over 900 videnskabelige udgivelser.
The Planck mission has provided a large amount of new knowledge, which has now been distributed on more than 900 scientific publications.
Da Big Bang fandt sted for de 13,8 mia. år siden var universet så tæt, at lys ikke kunne slippe igennem.
When the Big Bang happened 13.8 billion years ago, the universe was so dense that light could not pass through.
Først efter cirka 380.000 år kunne det udsendte lys fra Big Bang, bevæge sig gennem rummet.
It was not until some 380,000 years later that the light emitted from the Big Bang could move through space.
Og det er dette lys, der nu er kortlagt i højere detaljeringsgrad, end de få tidligere missioner har været i stand til.
And it is this light which has now been mapped to a higher level of detail than the few previous missions have been able to.
Udover at fastslå universets alder, er der også blevet arbejdet på at beregne, hvor hurtigt det udvider sig og forstå dets tilblivelse.
In addition to determining the age of the universe, work has also been done to calculate how quickly the universe is expanding and to understand its origins.
DTU-forsker påviser ekstrem udvidelse af universet
DTU researcher demonstrates extreme expansion of the universe
Den fremherskende teori i dag er, at universet begyndte med en fase, der kaldes inflation - en ekstrem udvidelse af universet på brøkdele af et sekund.
The prevailing theory today is that the universe started with a phase called inflation-an extreme expansion of the universe for a fraction of a second.
Det er så vokset til det gigantiske, synlige univers, vi kender i dag, og som stadig udvider sig.
It then grew to the gigantic, visible universe we know today, and which is still expanding.
Denne teori kan eftervises med konkrete målinger af et fænomen, der kaldes B-modes.
This theory can be confirmed through specific measurements of a phenomenon called B-modes.
Dette fænomen kan ifølge teorien kun opstå i forbindelse med inflation.
According to the theory, this phenomenon can only occur in connection with inflation.
Og faktisk er det i to omgange lykkedes for Hans Ulrik Nørgaard-Nielsen at detektere B-modes i datasættene fra Planck.
And, in fact, Hans Ulrik Nørgaard-Nielsen has succeeded in detecting B-modes in the data sets from Planck on two occasions.
Der er dog ikke bred enighed blandt astronomer om, hvorvidt der er tale om entydige B-modes og eftervisning af inflation.
However, there is no broad consensus among astronomers as to whether the B-modes and the demonstration of inflation are unequivocal.
Det sidste datasæt fra Planck-missionen blev udsendt af ESA tidligere på sommeren.
The last data set from the Planck mission was released by ESA earlier this summer.
Det kaldes 'The Planck Legacy Data Release' .
It is called ‘ The Planck Legacy Data Release '.
Dermed afsluttes en af dette årtusindes mest markante rummissioner, som DTU Space har sat et stort aftryk på.
This completes one of this millennium's most significant space missions, on which DTU Space has made a big mark.
Billedet øverst i artiklen viser fordeling af varme i universet i form af små afvigelser.
The illustration shows the distribution of heat in the universe in the form of small deviations.
Kortet er sammensat på baggrund af Plancks målinger af variationer i den kosmiske baggrundsstråling i form af rester efter lys udsendt i forbindelse med Big Bang, som er omsat til små temperaturforskelle.
The map has been composed on the basis of Planck's measurements of variations in the cosmic microwave background in the form of remnant light emitted in connection with the Big Bang, which has been converted into small temperature differences.
De røde områder er varme steder i universet, mens de blå er kolde steder.
The red areas are hot spots in the universe, while the blue are cold spots.
Det er især de blå, kolde områder, der er interessante.
Especially the blue, cold areas are interesting.
Den blå farve viser, at tætheden var større her end den gennemsnitlige tæthed i det tidlige univers.
The blue colour shows that the density was higher here than the average density in the early universe.
Dermed kan dannelsen af stjerner og galakser starte.
The formation of stars and galaxies can thus begin.

Såkaldt geo-engineering er en vej at gå, men der skal mere til.
So-called geo-engineering is one way to go, but more needs to be done.
Kemiingeniører er en uundværlig del af løsningen.
Chemical engineers are an indispensable part of the solution.
En ny opfindelse har fanget nyhedsmediernes opmærksomhed: Det schweiziske firma Climeworks' maskine, som kan trække CO2 ud af luften og binde den i undergrunden.
A new invention has caught the attention of the news media: The Swiss company Climeworks' machine that can draw CO2 out of the air and bury it underground.
Dette har fået mange medier til at kontakte en ekspert på området: Philip Loldrup Fosbøl, lektor ved DTU Kemiteknik.
This has led many media outlets to get in touch with an expert on the area: Philip Loldrup Fosbøl, Associate Professor at DTU Chemical Engineering.
”Hvis vi vil indfri målene i Paris-aftalen, så skal hele verden have negativ CO2-udledning omkring 2050 - ved at fjerne mere CO2 end der udledes - og dermed har vi brug for en teknologi, som kan trække CO2 ud af atmosfæren.
“If we want to meet the goals of the Paris Agreement, then the entire world needs to have a negative CO2 emission by around 2050-removing more CO2 than we emit-we need a technology which can draw CO2 out of the atmosphere.
Men én ny opfindelse er ikke en hurtig løsning på alle klimaudfordringer.
However, one new invention is not a quick fix to all climate-related issues.
Udover det faktum at særlige omstændigheder skal være til stede for, at man kan bruge Climeworks' teknologi (som tilstedeværelsen af geotermiske energiressourcer som på Island), så er det også nødvendigt, at udledningerne bliver reduceret på en bred skala, og meget mere forskning er et must:
Besides the fact that special conditions are needed for the new Climeworks technology (like the presence of geothermal energy resources, as, for instance, found on Iceland), emissions still need to be broadly reduced, and more research needs to be done:
Maskiner der kan fjerne CO2 fra atmosfæren kan være en del af løsningen, men vi skal først fokusere på at reducere udledningen,” siger Philip Fosbøl.
Machines to remove CO2 from the atmosphere could be a part of the solution, but we should first focus on reducing our emissions,” says Philip Fosbøl.
CO2-relaterede projekter på DTU Kemiteknik
CO2-related projects at DTU Chemical Engineering
Et andet forskningsprojekt, ‘ Sustainable process design with process intensification ', af ph.d.-studerende Rebecca Frauzem fra KT Consortium, arbejder også for en fremtid med begrænset CO2-udledning.
Another research project, ‘Sustainable process design with process intensification' , by PhD student Rebecca Frauzem at KT Consortium, also works towards a future with less CO2 emission.
Projektet, der afsluttedes i år, har udviklet et bæredygtigt design til at opfange og udnytte CO2 - en måde at imødegå udledningsproblemerne, der ikke er ulig Climeworks' maskine.
The project, completed this year, has developed a sustainable design for capturing and utilizing CO2 - a way of meeting the emission challenge not unlike the case of the Cilmeworks machine.
Rebecca Frauzem forsvarer sin ph.d.-afhandling i januar.
Rebecca Frauzem is defending her PhD thesis in January.
Og på CHEC-centret sigter projektet ‘ Thermally driven processes for CO2 reduction to fuels and chemical chemical building blocks ' - et samarbejde mellem DTU og Stanford University, der løber fra 2016 til 2024 - efter at udvikle en katalysator, som kan omdanne CO2 til ethanol ved lavt tryk og temperatur.
And at the CHEC centre, the project ‘Thermally driven processes for CO2 reduction to fuels and chemical chemical building blocks' - a collaboration between DTU and Stanford University, running from 2016 to 2024 - aims at developing a catalyst which can convert CO2 into ethanol at a low pressure and temperature.
”Næsten alle brændsler og kemikalier indeholder kulstof, der i dag fås fra fossile brændsler.
“Almost all fuels and chemicals contain carbon which today is obtained from fossil fuels.
Men CO2 er også en mulig kilde til kulstof.
However, CO2 is also a possible source of carbon.
Så når vi ikke længere ønsker at bruge, eller ikke er i besiddelse af, fossile brændsler, kan evnen til at omdanne CO2 til kemikalier vise sig at have stort potentiale i det lange løb,” siger Anker Degn Jensen, professor ved CHEC.
So, when we no longer wish to use or do not have any more fossil fuels, the ability to effectively convert CO2 into chemicals could prove to hold great potential in the long run,” says Anker Degn Jensen, Professor at CHEC.
Kemiingeniører: En uundværlig del af løsningen
Chemical engineers: An indispensable part of emission solutions
Philip Fosbøl er en ledende ekspert i geo-engineering-teknologier i Danmark, men, som han siger, geo-engineering er kun én del af et større billede:
Philip Fosbøl may be a leading expert of geo-engineering technology in Denmark but, as he says, geo-engineering is only one part of a greater scheme:
”Geo-engineering-teknologier som kan indfange og binde CO2 er én ting, men kemi- og biokemiingeniører kan beskæftige sig med alle dele af ”fødekæden” af drivhusgasudledning: I processerne før, under og efter udledning.
“Geo-engineering technologies that can capture and bind CO2 is one thing, but chemical and biochemical engineers can work in all parts of the greenhouse gas “food chain”: In the processes before, during and after emission.
Philip Fosbøl peger på et BioCO2-projekt på CERE med titlen ‘ Biogas upgrading for high-purity CO2 distribution '.
Philip Fosbøl points to a CERE BioCO2 project, ‘Biogas upgrading for high-purity CO2 distribution' .
I dag er den relativt rene CO2 fra opgradering udledt som et spildprodukt og ind i atmosfæren.
Today the relatively high-purity CO2 from the upgrading is emitted as a waste product into the atmosphere.
I stedet for at udlede CO2'en vil projektet forsøge at omdanne det til et værdifuldt grønt produkt, BioCO2, som kan sælges som et kommercielt produkt af biogasproducenter.
Instead of emitting the CO2, the aim of the project is to turn it into a valuable green product, BioCO2, which can be sold as an additional commercial product by the biogas producer.
Dette viser, at kemi- og biokemiingeniører har mange kort på hånden, når udfordringer relateret til klimaforandringer og udledning af drivhusgasser skal takles.
This goes to show that chemical and biochemical engineers have many cards on their hands in tackling issues related to climate change and emission of greenhouse gasses.
Som Philip Fosbøl formulerer det:
As Philip Fosbøl puts it:
”Den CO2 som et projekt som BioCO2 forsøger at producere kan være anvendelig i mad, biobrændsel, medicin, produktion og svejsning.
“The CO2 that a project such as BioCO2 is aiming to produce could be suitable for food, biofuel, medicine production, and welding purposes.
Mennesker bliver dog typisk udsat for en blanding af flere pesticider på én gang.
However, in the real world, humans are exposed to multiple pesticides at once.
Forsøg har vist, at mange pesticider forårsager nedsat fødselsvægt.
Studies have shown that certain pesticides can cause reduced birth weight.
I dette forsøg har rotter fået en cocktail af seks forskellige EU-godkendte pesticider ved doser, der hver for sig ikke ser ud til at medføre nedsat fødselsvægt.
They tested the effect of combining six EU-approved pesticides at doses that individually do not cause reduced birth weight.
Tre af pesticiderne er godkendt til brug i Danmark.
Three of the pesticides are approved for use in Denmark.
I to forskellige forsøg indgik hvert pesticid i cocktailen i en dosis, som i sig selv ikke har vist sig at have en skadelig effekt.
In two different studies, each pesticide was added to the cocktail at a dose that in itself is not harmful.
Rotteungerne blev udsat for cocktailen både før fødslen via moderkagen og efter fødslen via modermælken.
The rat offspring were then exposed to the cocktail both before birth via the placenta and after birth via the mother's milk.
Begge forsøg viste klart, at blandingen medførte nedsat fødselsvægt ved markant lavere doser end NOAEL for denne effekt for de enkelte pesticider.
Both studies showed that the mixture reduced the birth weight even with individual pesticide doses significantly lower than NOAEL.
Derved støtter resultaterne op om tidligere dyreforsøg, som viser, at udsættelse for blandinger af hormonforstyrrende stoffer - inklusive pesticider - kan medføre markante kombinationseffekter ved doser, hvor de enkelte stoffer ikke har nogen skadelig effekt.
The study results support previous findings from animal studies, which show that exposure to mixtures of endocrine disruptors-including pesticides-can cause significant combination effects at doses where the individual substances have no adverse effect.

DTU Space forsker i Mars' magnetfelt og har udviklet et magnetometer, der skal med ombord på den europæiske mission ExoMars.
DTU Space conducts research into Mars' magnetic field and has developed a magnetometer which will be aboard the European ExoMars mission.
Instituttets forskere bruger blandt andet målinger af magnetfeltet til at lede efter vand og is i Mars' undergrund.
For example, the Institute's scientists use measurements of the magnetic field to look for water and ice in the Martian substratum.
Forskningen er indtil videre baseret på magnetiske målinger fra forskellige internationale satellitmissioner som for eksempel Mars Global Surveyor.
The research so far is based on magnetic measurements from various international satellite missions such as Mars Global Surveyor.
I 2015 får DTU Space dog sit eget magnetometer på overfladen af Mars.
In 2015, however, DTU Space will have its own magnetometer on the surface of Mars.
Forskerne har nemlig udviklet et magnetometer, som skal med på den europæiske mission ExoMars, og det bliver det første magnetometer nogensinde, der lander på Mars.
Scientists have developed a magnetometer which will be aboard the European ExoMars mission, and this will be the first ever magnetometer to land on Mars.
Fakta om Mars' magnetfelt
Facts about Mars' magnetic field
Mars har, i modsætning til Jorden, ikke nogen intern dynamo, der skaber et stort globalt magnetfelt.
Unlike the Earth, Mars has no inner dynamo to create a major global magnetic field.
Dette betyder dog ikke, at Mars ikke har nogen magnetosfære, blot at den er mindre omfattende end Jordens.
This, however, does not mean that Mars does not have a magnetosphere; simply that it is less extensive than that of the Earth.
Mars' magnetosfære er meget mere simpel og mindre omfattende end Jordens.
The magnetosphere of Mars is far simpler and less extensive than that of the Earth.
Bagved bow shock'et ses MPB (Magnetic Pileup Boundary), som er grænsen til et område, hvor elektriske partikler bliver oplagret, og hvor magnetfeltet derfor er meget kraftigt.
Behind the bow shock is the MPB (Magnetic Pileup Boundary) which marks the outer boundary of the area where electrical particles are stored and where the magnetic field is therefore extremely strong.
Under MPB'en ligger ionospausen eller PEB (Photo-Electron Boundary), som er grænsen, der skiller de partikler, der kommer fra planeten fra de partikler, der kommer fra solvinden.
Below the MPB is the ionosphere or PEB (Photo-Electron Boundary), which is the boundary separating the particles travelling from the planet from those borne by the solar wind.
Disse skorpefelter på Mars giver anledning til små lokale minimagnetosfærer, dvs små områder hvor magnetfelts linier lokalt beskytter overfladen fra elektrisk ladede partikler.
The presence of these crustal fields gives rise to local mini-magnetospheres, i.e. small areas where the lines of the magnetic field locally protect the planet surface from electrically charged particles.
Mellem disse "bobler" kan feltlinier være forbundet til planeten i den ene ende og det interplanetare magnetiske felt (IMF) i den anden ende.
Between these ‘bubbles', one end of the magnetic field lines can be connected to the planet and the other to the interplanetary magnetic field (IMF).

The Danish PhD Dennis Valbjørn Christensen from DTU Energy was one of PhD students who received the Materials Research Society's Graduate Student Awards 2017.
”Det er meget fascinerende, især fordi man kan twiste egenskaberne på en række forskellige måder ved blandt andet at påtrykke en elektrisk spænding, sætte prøven ind i et magnetfelt eller deformere prøven”, fortæller Dennis, der i løbet af sin ph.
"It's very fascinating, especially as you can twist the properties in a variety of ways, for example by applying an electrical voltage, putting the sample into a magnetic field or deforming the sample," Dennis says.
d. besøgte flere internationale forskningsinstitutter.
He visited several international research institutes during his PhD studies.
Hans forskning, som på sigt gør det muligt at udnytte oxid-systemernes spændende egenskaber i elektroniske komponenter, bliver vurderet så banebrydende, at både Materials Research Society og American Physical Society valgte at anerkende ham med deres respektive graduate student awards for hans ”outstanding research”, som American Physical Society beskriver det i begrundelsen.
His research makes it possible to exploit the properties of oxide systems in electronic components, and it is assessed as having such high standards that both the Materials Research Society and the American Physical Society chose to acknowledge him with their graduate student awards.
American Physical Society (APS) er verdens næststørste organisation for fysikere, som udgiver videnskabelige tidsskrifter, herunder de prestigefyldte Physical Review og Physical Review Letters, arrangerer konferencer og uddeler priser for at promovere og støtte materialeforskningen.
The American Physical Society (APS) is the world's second largest organization for physicists who publish scientific journals, including the prestigious Physical Review and Physical Review Letters, as well as organizing conferences and awarding prizes to promote and support material research.
De er mest af alt et godt klap på skulderen, og jeg er ret stolt over at have modtaget dem”, fortæller Dennis, der præsenterede sit arbejde ved MRS ceremonien.
They are most of all a pat on my shoulder for my good work, and I'm quite proud to have received them," says Dennis, who presented his work at the MRS ceremony.
Programmet skulle ellers have været, at jeg skulle give et inviteret foredrag som prisvinder og have modtaget prisen til deres såkaldte GMAG business meeting, men nu bliver prisen sendt med posten i stedet.”
"I was supposed to give an invited lecture as prize winner and receive the prize at their GMAG business meeting, but now the prize will be sent by mail instead."

Xnovos GrainMapper3D™
Xnovo's GrainMapper3D™
En kombination af avanceret røntgenudstyr fra Carl Zeiss og specialudviklet software fra Xnovo muliggør analyser af materiale som metal og beton - helt ned til mindste kornstørrelse.
The combination of state-of-the-art X-ray equipment from Carl Zeiss and specially developed software from Xnovo enables analyses of material such as metal and concrete down to the smallest particle size.
Resultatet vises i 3D.
The result is displayed in 3D.
Forskerne har i mange år haft adgang til elektronmikroskopi, der kan analysere overflader af materialer.
For many years, researchers have had access to electron microscopy which can analyse surfaces of materials.
Hvis man lag for lag sliber materialet ned, kan man få et billede af strukturen i 3D.
If you grind the material down layer by layer, you get a 3D image of the structure.
Med denne teknologi går prøven altså til, og derfor er det umuligt at følge samme materialeprøve over tid og undersøge udviklingen.
This technology thus destroys the sample, and it is therefore impossible to follow the same material sample over time and study the development.
GrainMapper3D™ ødelægger ikke prøvematerialet under analysen.
However, GrainMapper3D™ does not destroy the sample material during the analysis.
Mikroskopet kan kigge på alt krystallinsk.
The microscope can look at everything crystalline.
Foruden metal og beton bliver det også benyttet til f.eks. mineraler og halvledermaterialer.
In addition metal and concrete, it is also used for, e.g., minerals and semiconductor materials.
