Space and Astronomy in general

Cloudy all night here. Can't see any of the explore eclipse. NASA show on YouTube has been fun though

Voyager 1 is starting to act weird. No word yet when it'll come back searching for the Creator.

Clearly it’s just reaching the edge of the simulation.

Many years ago I read a SF novel that used this as a plot point - people discover they're living in an artificial universe when their first interstellar probe hits the edge. Trying to remember which book it was - I have a vague idea it might have been one of Philip Jose Farmer's World of Tiers series.

It’s basically a spacecraft’s equivalent to Tom Brady winning a Super Bowl at 43.

So it was depressingly likely, is what they're saying.

This image of the Milky Way is 9 gigapixel's and contains roughly 84 million stars

Best comment I have seen

Spoiler:
But by all means, God created only us and don't masturbate otherwise she made all this for nothing.

I get chills from images like those. They freak me out, especially the ones like the massive nebulae. It just makes me feel so miniscule it can petrify me.

And the Milky Way as we see it is just one arm of our galaxy... It's not even the big show.

When this video first started to load I thought the movement was an optical illusion and I had the sensation of sort of falling into it. Weird!

Or look at the source, and scroll/zoom to your heart's content.

Any ideas why they would paint over parts of that image?

If you get up early maybe look for this... See 5 planets at once

Won't happen again until 2040.

Oh cool, I actually looked up this morning and wondered if I was looking at Mars and Jupiter. I missed their conjunction with Venus a few weeks ago. Mars had already moved on when I was up early enough.

We have a date to see the first full-color images and spectroscopic data from the James Webb Space Telescope!

10:30 a.m. EDT on Tuesday, July 12

NASA, in partnership with ESA (European Space Agency) and CSA (Canadian Space Agency), will release the James Webb Space Telescope’s first full-color images and spectroscopic data during a televised broadcast beginning at 10:30 a.m. EDT on Tuesday, July 12, from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Apparently the images next week will be pretty good.

The images are being taken right now. There is already some amazing science in the can, and some others are yet to be taken as we go forward. We are in the middle of getting the history-making data down. It’s really hard to not look at the Universe in a new light and not just have a moment that is deeply personal. It’s an emotional moment when you see nature suddenly releasing some of its secrets, and I would like you to imagine and look forward to that.

(just kidding about that last one, I hope)

CANNOT WAIT

(I am squeeing right now)

I hope everyone has seen the teaser image taken with JWST's Fine Guidance Sensor. This is a mosaic of ~30 hours of exposure. The filter on the FGS is clear, so it includes a broad range of wavelengths (and hence goes pretty deep!). It's not really one of the main imaging cameras, so the image quality will be at least as good on Tuesday...

This may be a stupid or obvious question:
are the spots black holes?

If so, that is completely nuts!

edit: it looks like those are stars... They must have black centers because the heat is out of range.
I see, based on the blog's criteria, 12 stars not counting partial ones off screen. Everything else is a galaxy

NM it looks like a possible 27 stars in that image:

Here's a comparison between that JWST teaser image and a more traditional terrestrial 'scope with a 6-hour long exposure:

This is what's making me so hyped for JWST.

The stars are bright enough that the “saturate” the detector. It can only count so many photons in a given pixel before it has a number too high for the number of bits it allots each pixel.

So it’s an artifact of the digital detector.

Thank you for wording that more accurately than I did

Dang it I'm at the dentist tomorrow

Also K2 comet closest approach to earth on July 14 this week.

Can watch live on virtual telescope if you don't have your own.

Closest approach to sun not until Dec so I guess coma will continue to grow? This thing is huge

They’ve moved things up a bit: the first image will be released Monday at 5 pm by President Biden!

Looks like 530 now according to the feed on NASA TV on YouTube.
