Very Large Telescope Interferometer

Yeah.

VLTI, so the Very Large Telescope Interferometer.

Mm-hmm.

Now, this new star is called S301.

They reckon it's gonna be 10 years of observations-

Mm-hmm

... using the VLTI and the Extremely Large Telescope-

Yeah, yeah, yeah, yeah

VLT or something, isn't it?

VLT! Yeah, VLTI.

So the Very Large Telescope Interferometer.

Now, this new SAR is called S301.

And this is what's so exciting because this star is giving us the opportunity to actually directly measure the spin of the supermassive black hole at the centre of our galaxy.

Wow.

So when you're going to be able to do it for a number of years, they reckon it's going to be 10 years of observations using the VLTI and the extremely large telescope that is being built.

But it should be doable.
