SOPA Cabana (by Dan Bull)

New Space Telescope launched, 1000 times sharper than Hubble

>> ^eric3579:

The very high angular resolving power will be achieved when used in conjunction with a ground-based system of radio-telescopes and interferometrical methods, operating at wavelengths of 1.35–6.0, 18.0 and 92.0 cm. With its Earth-based companions, it will form a network able to provide detailed images of the universe at 1,000 times the resolution attainable using the Hubble Space Telescope. -wiki

The title is quite misleading. Hubble is a visible/UV telescope, where this one is a radio telescope. They image completely different parts of the spectrum. Think of the comparison of the ground-based VLA and VLT telescopes: quite different instruments.

Yeah, how can any radio telescope be remotely as sharp as a visible light telescope? At that frequency it's hard to get high angular resolution from a single dish.



Ok, that's believable. But the title and summary clearly imply that this single instrument will be 1,000 times sharper than the HST.

New Mexico - The best place in the Universe...

Comment hidden because you are ignoring dag. (show it anyway)

I liked it.

I visited Roswell a few years ago. I have to say I was pretty disappointed. The alien "museum" was a gift shop.

I was much more impressed by the VLA just down the road. (I had seen Contact recently).

My parents live in Las Cruces and there are many, many aliens there. But it is a border town.

Hubblecast: Unveiling the Veil nebula

Was watching Cosmos just last night, Episode 11 where they feature the VLA in New Mexico. Interestingly, the radio energy that the VLA measures is so faint, all of the energy the VLA has ever detected over the years still doesn't equal the amount of energy that a snowflake releases when hitting the ground. That's just...wow.
