LISA Pathfinder en route to gravitational wave demonstration

"

{lang en} ESA’s LISA Pathfinder lifted off earlier today on a Vega rocket from Europe’s spaceport in Kourou, French Guiana, on its way to demonstrate technology for observing gravitational waves from space. Gravitational waves are ripples in the fabric of spacetime, predicted a century ago by Albert Einstein’s General Theory of Relativity, published on 2 …

In search of the biggest bangs after the Big Bang

On 2 December 2015 the European Space Agency ESA will launch the satellite LISA Pathfinder, an important technology demonstration mission for measuring the gravitational waves in space predicted by Einstein. With gravitational waves scientists expect to be able to make new discoveries about objects such as compact binary stars and merging supermassive black holes, which …

Black holes behave like Matryoshka dolls

An international team of astrophysicists has established that supermassive black holes behave like small stellar black holes. They made their discovery by observing a supermassive black hole that has torn apart a star, causing a surge of gas towards it. Normally such a change in the gas flow takes too long to detect. But this …

Dark matter or the smell of sulphur?

An international team of astronomers has found a new explanation for enigmatic X-rays in clusters of galaxies, the largest bound objects in the Universe. These X-rays, at very specific energies, may come from an electric charge exchange between cold hydrogen gas and bare sulphur ions. Previously these X-rays were attributed to sterile neutrinos, a possible …

Gelderland invests in space cluster

De Provincie Gelderland zet € 195.000 in voor de opzet van een Smart Space Cluster, dat innovatieve producten ontwikkelt voor de ruimtevaart. In het cluster – waaraan SRON deelneemt – werken aerospacebedrijven samen met kennisinstellingen. De hoogwaardige technologie moet eveneens toepasbaar zijn in de gezondheidszorg, voeding- en maakindustrie. Gedeputeerde Michiel Scheffer: ‘Smart Industry is de …

Count down has started for balloon mission on Antarctica

Vandaag zijn twee SRON-onderzoekers aangekomen op Antarctica, waar ze een ballonmissie van de NASA voorbereiden. Half december tilt deze ballon infrarood-detectoren van SRON/TU Delft naar de stratosfeer, om daar vanaf de rand van de ruimte onderzoek te doen naar het ontstaan van sterren en planeten. Systems engineer Wouter Laauwen doet hier in blogs regelmatig verslag …

European research grant for exoplanet researchers

 De exoplaneet-onderzoekers dr. Jean-Michel Desert (Universiteit van Amsterdam/SRON) en dr. Ir. Frans Snik (NOVA/Universiteit Leiden) krijgen een Starting Grant van de European Research Council (ERC). Deze prestigieuze beurs van 1,5 miljoen euro is bedoeld voor aanstormend wetenschappelijk talent om hun eerste onderzoeksgroep te vormen. Jean-Michel Desert (Universiteit van Amsterdam/SRON) gaat de komende jaren de verscheidenheid …

Black hole caught feasting on a star

A group of astronomers with SRON researchers have detected the last ‘cry’ from a star that passed too close to the central black hole of its host galaxy and was being destroyed and ‘swallowed’ – a phenomenon known as a tidal disruption event. The study, based on the observations of X-rays emitted by leftover material …

Heel Nederland kijkt weer sterren

Op woensdag 21 oktober om 21.25 uur zendt omroep MAX op NPO 1 weer het tv-programma Heel Nederland Kijkt Sterren uit. Live vanuit de Oude Sterrewacht in Leiden nemen Jeroen Latijnhouwers en Govert Schilling de kijker mee op een bijzondere ruimtereis tussen hemel en aarde. SRON sponsort dit programma. Naar aanleiding van het succes van …

Herschel-HIFI probes skin of Orion

The Herschel Space Observatory has revolutionised our understanding of what star forming clouds look like. Photometric images of the dust emission, obtained at far-infrared wavelengths, have revealed spectacular networks of filamentary structures where stars are born. Those newborn massive stars (more massive than 8 solar masses) release large quantities of energy as ionizing UV radiation and …
