Trying to solve the global methane puzzle
A group of international scientists have joined forces to synthesize the scientific evidence on intriguing decadal trends in the greenhouse gas methane. They.48 Scientists from 34 Institutions worldwide, including SRON, cooperate under the umbrella of the Global Carbon Project (GCP), trying to solve the complicated global methane puzzle. The aim is to reevaluate the recent scientific literature in support of the contribution of IPCC Working Group 1 to its, soon to be released, 5th Assessment Report. |

Second iSPEX Measurement Day
Donderdag 5 september vindt de tweede Nationale iSPEX-meetdag plaats. De succesvolle eerste meetdag op 8 juli, leverde bijna 6000 metingen op van deelnemers die met behulp van het iSPEX-opzetstukje op hun smartphone-camera opnamen maakten van de blauwe lucht en het fijnstof daarin. De dag erna kwamen nog eens enkele duizenden metingen binnen. |

Thousands of measurements on Dutch iSPEX Measurment Day
De eerste Nationale iSPEX-meetdag heeft 5000 metingen opgeleverd. Daarmee zijn genoeg gegevens gegenereerd om de iSPEX-meetdag een valide wetenschappelijk experiment te noemen. iSPEX-teamleider Frans Snik is blij dat de respons zo massaal was, ondanks het lange wachten op mooi weer en de aangebroken vakantieperiode. |

Today first National iSPEX Measurement Day
Na lang wachten op mooi weer is het eindelijk zover: duizenden Nederlanders gaan met behulp van het iSPEX-opzetstukje op hun smartphone-camera metingen verrichten aan fijnstof in de lucht. Voor het wetenschappelijke experiment is boven heel Nederland een grotendeels blauwe lucht noodzakelijk, en dat is vandaag het geval. |

Thousands of citizens have enlisted for the national iSPEX Measurement Day
Op een zonnige dag tussen medio mei en eind juni gaat Nederland massaal met behulp van het iSPEX-opzetstukje op de smartphone-camera metingen verrichten aan fijnstof in de lucht. Sinds februari van dit jaar hebben al duizenden Nederlanders zich aangemeld voor deelname aan de landelijke iSPEX-meetdag. De productie van 10.000 opzetstukjes is in volle gang; ze worden rond half mei verstuurd, en dan is ook de bijbehorende gratis app klaar. De inschrijvingstermijn van iSPEX loopt tot eind april en de komende twee weken hebben geïnteresseerden dus de laatste mogelijkheid om een opzetstukje via longfonds.nl/ispex te bestellen. |

New type of telescope can possibly discover extraterrestrial life
A team of Dutch astronomers has shown that with a new type of telescope it might be possible to find signs of extraterrestrial life within the next 25 years. Certain gases exhaled by organisms can, in principle, be observed in the atmospheres of exoplanets – planets orbiting stars other than our sun. This idea, which was developed back in the 1960s, has now been linked to a new observation technique that makes use of relatively cheap flux collectors, large reflecting telescopes that cannot make sharp images but collect enough light for accurate spectroscopy to be performed. This study will soon be published in The Astrophysical Journal. |

HIFI strives for the best and cures its last frequency problem
In an attempt to take the scientific output of the molecule hunter HIFI to the limit, the HIFI-team has cured a small frequency range (band 3B). Knowing that there was a possibility of losing this band the team had postponed the attempt until the very end of the operations, due in April 2013. HIFI - onboard ESA's Herschel Space Observatory - has been producing lots of scientific data now for the past three years, after a careful commissioning of the highly complex instrument. With the band 3B observations the team hopes to finalize its survey of molecular complexity in the richest chemical sources in our Milky Way. |

Chameleon pulsar baffles astronomers
An international team - led by Dutch astronomers (SRON, NOVA and ASTRON) - has made a tantalizing discovery about the way pulsars emit radiation. The emission of X-rays and radio waves by these pulsating neutron stars is able to change dramatically in seconds, simultaneously, in a way that cannot be explained with current theory. It suggests a quick change of the entire magnetosphere. In their research the team combined observations from the X-ray space telescope XMM-Newton and the radio telescope LOFAR (among others); the research results appear in the journal Science tomorrow. |

Breakthrough in super-terahertz detection technology
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 - is able to operate at the exact frequency that is needed to enable the detection of the astrophysically important neutral atomic oxygen (OI) line. This is very good news for astronomers who need to study the oxygen lines from different astronomic sources to trace star formation and galactic evolution. It is also an important milestone in the development of the technology for the candidate balloon mission GUSSTO (NASA). The research results appeared this month in Applied Physics Letters. |
