LOFAR is the Low-Frequency Array for radio astronomy, built by the Netherlands astronomical foundation ASTRON and operated by ASTRON's radio observatory.
LOFAR will be the largest connected radio telescope ever built,[citation needed] using a new concept based on a vast array of omni-directional antennas. The project is based on an interferometric array of radio telescopes using about 20,000 small antennas and at least 48 larger stations. 40 of these stations are distributed across the Netherlands, five stations in Germany, and one each in Great Britain, France and Sweden. Further stations may also be built in other European countries. The total effective collecting area is up to approximately 300,000 square meter, depending on frequency and antenna configuration. The data processing is performed by a Blue Gene/P supercomputer situated in the Netherlands at the University of Groningen.
LOFAR was conceived as an innovative effort to force a breakthrough in sensitivity for astronomical observations at radio-frequencies below 250 MHz. Astronomical radio interferometers usually consist either of arrays of parabolic dishes (e.g. the One-Mile Telescope), arrays of one-dimensional antennas (e.g. the Molonglo Observatory Synthesis Telescope) or two-dimensional arrays of omnidirectional antennas (e.g. Antony Hewish' Interplanetary Scintillation Array).
A slap to the face when you don't get your way
You tell me all about your situation Please keep to
Yourself
I don't want to hear you but you keep on telling me
I'm sick of you
Don't worry about me
You think about yourself so much
You always think it's all about you, Don't worry about me
You think about yourself, so much.
Do you like what you have?
Now I'm taking it back
I wonder if you even know what you say
You bore me with your selfish conversation
Please keep to yourself
No one wants to hear you but you keep on telling me
I'm sick of you
Don't worry about me
You think about yourself so much
You always think it's all about you, Don't worry about me
You think about yourself, so much.
Do you like what you have?
I'm gonna take it away
If you come back down
Will you listen to me?
When you come back down
