In de week van 6-10 mei komen sterrenkundigen uit de hele wereld samen in Amsterdam voor een symposium over neutronensterren. In debatcentrum Felix Meritis bespreken zij de jongste resultaten van het onderzoek aan neutronensterren, ineengestorte kernen van reuzensterren die als supernova’s zijn geëxplodeerd. Vanwege hun extreem samengebalde materie kunnen neutronensterren uitstekend dienen als laboratoria om …
HIFI opened up new window on Molecular Universe Today, after more than 3,5 years in space, the liquid helium coolant on board the Herschel space observatory (ESA) has finally run out. This means that the Dutch molecule hunter HIFI – one of its three instruments – has ceased to collect spectra. But the scientific heritage …
ESA’s Herschel space observatory has solved a long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994. Water in Jupiter’s atmosphere. During the spectacular week-long collision, a string of 21 comet fragments pounded …
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 …
ESA’s Herschel space observatory is expected to exhaust its supply of liquid helium coolant in the coming weeks after spending more than three exciting years studying the cool Universe. Herschel was launched on 14 May 2009 and, with a main mirror 3.5 m across, it is the largest, most powerful infrared telescope ever flown in …
iSPEX1 The registration for the great citizen science project iSPEX, “Measuring aerosols with your smartphone”, is open. From today you can order an add-on for you smartphone, to change this everyday tool into a scientific instrument. Anyone with an iSPEX add-on can participate to the large measurement day scheduled for late spring. Please click here …
On Tuesday, February 12 State Secretary Dekker received the Strategic Plan for Astronomy in the Netherlands 2011-2020 from the hands of Professor Ralph Wijers, Chairman of the National Committee Astronomy. Click here to read more in Dutch.
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 …
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 – …
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 …
