An international team of researchers led by SRON and TU Delft have successfully demonstrated a superconducting heterodyne receiver with an unprecedented high sensitivity at 4,7 THz in frequency or 63 micrometers in wavelength. The so called super-terahertz heterodyne receiver – about 85 times more sensitive than its predecessor, operating near the quantum noise limit – …
SRON astronomers have been awarded four weeks of observation time at the European X-ray telescope XMM-Newton (ESA) to study a black hole and the origin of chemical elements in the universe. It is exceptional that the astronomers have received so much time on this workhorse of X-ray astronomy. Due to the huge international interest in …
{multithumb thumb_width=300} As we are getting ready for the winter in the northern hemisphere, seasonal changes on Saturn’s biggest moon are also starting to be rapidly noticed. An international team of scientists has observed the most dramatic increase in concentrations of trace gases since the Cassini satellite arrived at Saturn in 2004. These changes are …
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 …
{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 …
{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. …
{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 …
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 …
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 …
{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 …
