Planetary researchers from SRON Netherlands Institute for Space Research and the University of Amsterdam have calculated that an exoplanet with water clouds reflects starlight that can be very strongly polarized. This ‘rainbow signal‘ can be used to recognize water clouds. Clouds of water droplets in the planet’s atmosphere enormously increase the chances of liquid water …
Hypergiant star turns out to be ‘missing link’ after 30 years
{multithumb thumb_width=200} A team of scientists from six European countries reported today they have finalized a thirty years long investigation of a hypergiant star that crossed the Yellow Evolutionary Void. In that period the star’s surface temperature quickly rose from five to eight thousand degrees. With this discovery a crucial ‘missing link’ in the evolution …
iSPEX wins Dutch prize for public outreach
{multithumb thumb_width=200} Het team van iSPEX neemt de prijs in ontvangst Het team van de Universiteit Leiden – waarin SRON deelneemt – heeft met het iSPEX-project (‘Meet fijnstof met je smartphone’) de Academische Jaarprijs 2012 gewonnen. Tijdens een spannende finale liet iSPEX woensdagavond in de Leidse Stadsgehoorzaal de twee andere teams, uit Groningen, achter zich. …
Large water reservoirs at the dawn of stellar birth
{multithumb thumb_width=200} ESA’s Herschel space observatory has discovered enough water vapour to fill Earth’s oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star. Stars form within cold, dark clouds of gas and dust – ‘pre-stellar cores’ – that contain all …
The Hague sets 68 million aside for Dutch space sector
Good news from The Hague! Today was announced that the intended cuts on the Dutch space sector (30 million euros) have been cancelled for the greater part. In answer to requests from a.o. the Parliament, the Dutch government has now set aside 68 million euros for Space in the years 2012-2015. sentinel4 See the full …
Human contribution to emission of hothouse gases dates back to the Roman Empire
Air bubbles in old ice cores render proveResearchers from the Universiteit Utrecht, SRON and other international institutes have found that humans have contributed to the emission of the hothouse gas methane since the time of the Roman Empire. That is a lot sooner than researchers have always thought. The results appear on 4 October in …
Cold crystals shed light on the formation of our planetary system
{multithumb thumb_width=200} An international team of astronomers found that the building blocks for planets in a baby brother of our solar system probably formed under circumstances that closely resemble the circumstances in our early Solar System. The discovery suggests that a planetary system like ours can form around very different stars. The results are published …
Open Days SRON
{multithumb thumb_width=280} SRON Netherlands Institute for Space Research will be opening its doors again to the public. On Sunday 7 oktober 2012 visitors are most welcome in Utrecht and on Sunday 21 oktober 2012 in Groningen. There will be prsentations, demonstrations, lectures and films on the latetst developments in space science. Children can enjoy a special programme. At both locations …
Fireworks in the early Universe
{multithumb thumb_width=300} Galaxies in the early universe grew fast by rapidly making new stars. Such prodigious star formation episodes, characterized by the intense radiation of the newborn stars, were often accompanied by fireworks in the form of energy bursts caused by the massive central black hole accretion in these galaxies. This discovery with the Herschel …
ALMA Band-9 receivers detect sugar near Sun-like star
{multithumb thumb_width=250} With the help of the ALMA Band-9 receivers built by SRON and other parties, sugar molecules have been detected in the gas around a young Sun-like star. This is the first time sugar has been detected in the space around such a star. The discovery shows that the building blocks for life are …
