Solar System discovered 127 light-years away

Well, I suppose it wasn’t suddenly discovered. There was some work for about 6 years studying the star HD10180 using a planet-finding instrument called “the HARPS spectrograph”, attached to ESO’s 3.6 metre (11.8ft) telescope at La Silla, Chile.

Scientists say it has about 7 planets, which makes this solar system hold the record on the number of planets so far.

Astronomers spotted the planets using spectroscopic analysis and the “wobble method,” where they look at slight wobbles in a star. These wobbles are caused by the gravitational forces from planets rotating the star, and researchers can extrapolate probable size and mass of the planets

Sadly, from what scientists have calculated, there are no planets that could sustain life or be hospitable enough for colonization, which makes this solar system improbable to colonize.

DIY CD Solar Concentrator -attempt

Well, I thought of building a solar concentrator out of cds, but it ended up being just a … “reflector”.

It could work by having something painted in black and placed in the center of this thing, but I’ll try to build a concentrator some time.

Here are the pictures:

Actually, just before sunset, a couple of the cds( I think about 3-4, but they are 12 !) reflected the light into one spot: it was super bright. Now I know that if I build this correctly, I can have a powerful concentrator that can heat things so much they can catch fire !

Fresnel Lens- Dangerous solar power! :))

This is the most awesome solar-powered project I’ve ever seen in terms of the effects of such a contraption.

These fresnel lens are very practical due to their design.They’re very compact for their light focusing power.

Focusing power, you ask? That’s just my word for this:

You’ll see cement turning red hot, melting glass, and water turning boiling hot in a matter of seconds!!!

They’re available for buying on ebay\amazon. Just search for “fresnel lens”. They’re very cheap.

Make a solar marshmallow roaster(or, if you really want, a solar penny melter :)) )

I discovered a guide on how to make a marshmallow cooker(just for fun ), that is solar powered.

The funny part is, if you improve this, you can melt coins .
