Haha, not my title, the article’s. I don’t change them too often because it disrupts my flow going through my RSS feeds while I select things I want to get into in depth myself, and I know publishers make these decisions for a reason. The text is pretty ok though. Feel free to downvote them.
Habitability in this usage means "a place where humans can live, either with or without technological assistance". In terms of temperature, this means the range of temperatures where machinery can reliably function. Of the temperatures found in the universe, this machinery-functionable range is actually extremely narrow
There’s not really any data other than a rough distance from its star. The atmosphere could be thick enough and with the right combination of greenhouse gases that the temperature at the equator is 23°C year round. We do know that it’s only receiving ~30% of the energy from its star as earth does from the sun, which is what they’re basing the low temperature estimates on.
And it’s not like once we have the technology needed to travel 146 light years that we couldn’t do something insane like deploy mirror-film solar cells or something to capture extra heat in orbit around the planet and warm the entire planet and terraform it for our usage.
Headline suggests that this is an observed fact, rather than the result of a simulation based on a model created by several EU scientists.
Furthermore the article asserts that “The observed motions … can only be properly explained with this “flat” mass distribution.” That premature assertion, based on this paper
Thanks! My opinion is that images from NASA, ESA etc should always link to the source. They always include interesting information about what is in the image. It is also nice if I don’t need to search the database for ages.
Yeah… I kind of wish it was a request of the channel. I’ve found a few of the sources now and it’s mostly on this channel people seem to post other people’s images with no references
I guess OP found this in yesterday’s ‘Astronomy Picture of the Day’, which includes the link you sent. Would’ve cost a second to include it in the post.
This color mosaic uses the near-infrared, green and violet filters (slightly more than the visible range) of the spacecraft’s camera and approximates what the human eye would see.
It’s the TRMNL. I plan to share my plugin eventually too, but need to develop a few different layouts for different display options before I can submit it, so it’s just a private plugin for now.
I like it a lot! As a software developer that stares at LCD screens all work day, I’m really into e-ink/single-purpose tech outside of work. I found their UI framework docs for custom plugins a bit lacking, but eventually got everything working.
The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it’s sensed light from a galaxy only 280 million years after the Big Bang, the most distant galaxy ever detected.
Prior to the JWST, we had no infrared telescopes with large enough mirrors to detect light from the early galaxies. The Hubble can see near-infrared light, but only has a 2.4-meter mirror. It found only one galaxy from the Universe’s 500 million years. The Spitzer Space Telescope was a dedicated infrared telescope, but it only had an 85 cm mirror. Not only does the JWST have a much larger mirror, but detector technology has advanced so much that the veil obscuring the early Universe is being lifted one ancient galaxy at a time.
Those numbers are interesting but what is the result of this? eg. because NASA has approximately 35% women and 30% minorities, it has what level of increased productivity? what has actually come out of this?
