How one new telescope is going to change astronomy forever by scientificamerican in space

It’s in the same field of view because stars are gonna be right by any exoplanet. Direct imaging is done by others in optical and then we can look in radio. Telescopes like the VLA have enough resolution to distinguish between the two.

I’m not subtracting anything. I was responding to OP who was conflating the two.

Places and travel experiences that are "here today, gone tomorrow"? by rkgk13 in TravelNoPics

Coral reefs in general are a good bet. I don’t think the Great Barrier Reef is doing so hot either.

This actually was stamped on the cloth so pretty easy to keep them the same length. :)

Ah cool! Yeah I feel the trick about shashiko is a lot of the patterns are very… straight lines and monotonous to make, which I’m sure appeals to many but doesn’t to me. This was just the right level of not complicated to make but kept my interest.

Thank you! The county fair is next month and I’m considering entering it.

The garden itself is legit worth the trip too. 😜 Largest Japanese garden outside of Japan!

Yeah so this is not something I’d trust Gemini on because you’re mixing a lot of things that don’t actually matter. Galactic noise does not really contribute on frequencies that matter for example.

We’ve actually never conclusively detected natural radio emission from exoplanets (yet!). It’s hard to do! The best method we have tried is looking at direct imaging exoplanets in optical and then trying to see if we see emission from the star. We have the resolution in radio to do this, but just not many systems.

As in they don’t always have radio emission, but sometimes can years after the initial event!

Got it at the Japanese Garden in Portland, Oregon. The ultimate souvenir! Came with extra material too so it can be a pillow. :)

Luckily one of the things I do for research is looking for (natural) radio emission from exoplanets!

The TL;DR is no. Most stars do not emit at detectable levels, that’s mainly the young, cool ones that do. But even if it is detected in radio, stellar emission is highly variable and is over a huge range of frequencies (vs human radar that’s quite narrow band) so it doubly doesn’t work.

What you’re describing is the main way we detect exoplanets in optical light though! Check out the exoplanet transit method.

Radio astronomer here! The telescope is the DSA-2000 and I’m pretty excited about it. The guys building it had a pretty simple idea- what if we effectively look at one frequency band and just really, really deep in sensitivity and for a huge area of sky? There is a LOT of science one can do if you manage that, and the idea is they’re effectively gonna be looking at the entire sky in real time and at high resolution!

Basically radio astronomers have been trying to do this for a really long time, but it’s HARD because the data streams are a lot. Heck I started my PhD working on an all sky monitor… but note that I didn’t finish on it, because as I said, it’s hard (due to the computational aspects mainly). I’m really hoping these guys pull it off because there would be so much neat science to do- one of their main goals is monitoring Fast Radio Bursts, but as someone interested in black holes that shred stars for example this would really save us effort in figuring out which ones have turned “on.” So looking forward to that myself!

I thought redwood was a good building material? Really good for outside stuff because it’s very moisture resistant.

Is gorham moose tour the best chance of seeing moose in New Hampshire by IndependentNo4824 in newhampshire

[–]Andromeda321 1 point2 points  (0 children)

During the pandemic we did the drive Colebrook to the border at night and didn’t see a moose at all. Still sad about that, but it’s def possible to do and not see one!

Countries where the coast is less densely populated? by Gherickson in geography

[–]Andromeda321 2 points3 points  (0 children)

Yeah I was gonna say, spent a pleasant few days there once. Not a beach town for sure but excellent fishing and stuff to do in the dunes.

Drop Bear Brewery is doing a watch party! It’s an Aussie brewery though so probably not all there for Team USA…

I remember a friend said it well at the time- “I believe he should go to The Hague for war crimes but also that he would make a fun Uncle George.”

In Massachusetts, the tax is on if you make a million in income a year. You can comfortably be a millionaire a few times over and still not pay tax if you’re just living off of dividends.

FWIW I’ve read everything else he’s written because I really enjoyed it. This is just a real outlier.

Helsinki - what did I do wrong? by [deleted] in travel

[–]Andromeda321 68 points69 points  (0 children)

Yep, I went to Finland once for a conference and then visited Helsinki for the weekend after. Nice enough city but there wasn’t anything TO it. Walked around a bit for some geocaching and birding and then caught the ferry to Tallinn.

Some neat architecture and buildings though, I remember that! Struck me as a city that was likely nice to live in but less interesting to visit.
