One of the most prestigious projects is about to take place in south Africa called the SKA (Square Kilometer Array). SKA is a group of smaller parabolic antennas which together combined will create a huge telescope array that is 3000 km in diameter and will occupy 12.5 million hectars.
The sensitivity of this array of telescopes will exceed 50-100 the sensitivity of current radio telescopes around the globe. The building project itself it about to cost 1.5 billion euros (1.5 followed by 9 zeros €)!
This is a major breakthrough for astronomy. Astronomers will have now a big advantage in order to uncover the secrets from the big bang aftermath shortly after it took place.
The SKA is about to be operable in year 2025. Let us cross our fingers and wish all involved project members congratulations for this opportunity and good luck during the assembling period.
For almost a week ago we received our radio telescope which was originally owned by the institute of astronomy at Lund’s university. The telescope was used primarily by astronomy students. It weights around 200 kg and is 1,20 m across in diameter. With this telescope we will be able to observe regardless weather conditions and even at daytime the sun, some strong radio sources in Milky way and many other things.
At the same time we have spoken with the architects from the municipality office regarding an extension building northside from our observatory. I will publish soon some blueprints which will give a clear picture of how our future observatory will look like. Because the building plans are not official yet, I’ll have to wait from publishing any further information regarding construction plans until all plans are set.
Last night I held a lecture about Galileo’s telescope for members in our Tycho Brahe astronomy society here in Skåne. I would have kept going with my entire presentation for more then a hour but my time was limited to half. The lecture was describing the difficulties Galileo encountered in order to build his first telescope and the differences and achievements with later versions of his telescopes, as well as his first observations based on Jupiter, Venus and the moon that changed the world’s view.
Unfortunately Bengt Rosengren a member in our astro-society felt ill and couldn’t attend our meeting. He has created a Galileo telescope replica which would be available for our attendees to study. I am providing an image from his replica here.
