Every second, something new in the heavens
| Submitter: | Jason Hessels |
| Description: | The sky is constantly changing. By exploring the heavens in the 4th dimension of time we can learn a lot about how stars are born, die, and shape the Universe we live in. That's the focus of a recent article in the Dutch newspaper NRC, which featured a 3-page spread about "time-domain" astronomy in its weekend science section. LOFAR featured prominently in the article: "LOFAR 2.0, de door ASTRON ontwikkelde aanstaande upgrade van de radiotelescoop met nieuwe software en meetstations, zal veel nieuwe `sterrenfilms' opleveren met een nog hogere resolutie in ruimte en tijd." ("LOFAR 2.0, the upcoming upgrade of the radio telescope developed by ASTRON with new software and measurement stations, will also provide many new `star films' with even higher resolution in space and time.") Astronomers are probing the ever-changing sky on timescales from nanoseconds to decades and more, as beautifully illustrated in the article. They're discovering unexpected phenomena that reveal the extremes of the Universe. LOFAR provided a breakthrough in our understanding of long-period transients; we're excited to see what LOFAR 2.0 will discover! |
