Well well well, if it isn't the consequences of my actions


🔴 LIVE NOW
Tune in to learn what it took to design, build, test, and launch the @NASAMars Spirit and Opportunity rovers. (Spoiler: It wasn't easy!)

For fans of the recently released #GoodNightOppy, this is definitely a must watch! ⬇️

Commander Moonikin Campos here. I’ve had a very busy day, taking selfies with the #LunaTwins, writing Tweets, capturing data from lunar orbit…

Sadly, I’ve got to let the #Artemis social media nerds have their account back.
#NASAArtemis #Artemis



Aside from me taking over the #Artemis @Twitter account, today was exciting for another reason — @NASA_Orion has hit its maximum distance from Earth, at over 270,000 miles!

I have accomplished so much. 🥹

Listen to (another!) black hole 🔊
This one bangs. Literally. Material surrounding a black hole can produce intense bursts of electromagnetic radiation that can bounce off clouds of gas & dust in space. @chandraxray's sonification turns these ''light echoes'' into sound.

LIVE NOW: The @NASA_Orion spacecraft is about halfway through the #Artemis I mission around the Moon. Hear from NASA leaders on the upcoming milestones leading up to splashdown on Dec. 11. twitter.com/i/broadcasts/1MYxN…

Tonight at 5pm ET (22:00 UTC), @nasa leaders will provide an update on the #Artemis I mission, which we are now halfway through!

#OTD in 1967, Jocelyn Bell Burnell provided the first direct evidence of pulsars, rapidly rotating neutron stars. Decades later, the first exoplanets were found – orbiting pulsars, helping launch a new era of discovery. #MondayMotivation: Change the world

This is a language joke. Someone tried to send this to their Japanese dad as a meme.
Feel free to ask me why it's funny.


In 1977 NASA's robotic Voyager 1 spacecraft captured the first full view of Earth & the Moon together in a single frame. Today @NASA_Orion, designed to carry astronauts to the Moon, sent its own view of the Earth-Moon system. Follow along with #Artemis I: blogs.nasa.gov/artemis/

Privacy Considerations for 4 types of people

blog.devgenius.io/privacy-sett…

in reply to The New Oil

Frankly, this is a pretty low-quality article. There are a lot of typos and grammar errors, and much of the advice is questionable at best, like recommending people keep location tracking on. It's also unclear to me how the "four types of people" are actually represented in each section. I find most of what you share insightful and helpful so this surprised me.
in reply to rolltime

@rolltime Agreed, It excludes teenagers in some categories and lacks depth.


Our universe is speckled with stars, with billions just in our galaxy. Some stars live alone or in twos or threes, but others are bound together by gravity into much larger communities. In honor of @NASAHubble’s exploration of #StarrySights, let’s talk about star clusters! 🧵 1/6
#NASAUniverse


Globular clusters are stellar "dinosaurs" scattered throughout the universe, containing some of the oldest stars in the universe. These clusters can contain anywhere from tens of thousands to millions of stars, packed tightly together in a dense clump. 3/6
#NASAUniverse


Star clusters are divided into a few different types, based on how many stars are in a cluster and how tightly they’re bound by gravity. Stars in clusters typically have a shared origin, and they can live very close together or can be spread out over hundreds of light-years. 2/6
#NASAUniverse


Open clusters have fewer members, usually a few hundred stars or less. Most open clusters are much younger than globular clusters, and they’re also much less dense and less tightly bound than globular clusters. 4/6
#NASAUniverse
in reply to NASA

Just to let you know that your threads do not have the posts linked to each other, plus they are not being posted in order.


Scientists are interested in how star clusters form and evolve. Some disperse and spread out over time, while others remain tightly bound together by gravity. The different types of stars in clusters also have various life spans, so they change and die off as a cluster ages. 5/6
#NASAUniverse


Many different @nasa observatories study star clusters using different types of light. Alongside @NASAHubble, we’ll be highlighting how some of our other telescopes help us learn about these stellar communities! 6/6

Electronics question – LED resistors, boosts welcome

I pulled apart an LED bulb. I can't remember the lumens but think it was 200lm. I want to use the individual LEDs with an Arduino but don't know what resistor to use with each as I'm not sure how big a punch each one packs. The resistor for all 36 tiny LEDs is in the second photo – looks like [brown black black black red] to my eyes.

Any idea how I can calculate the resistor needed for one bulb please?

Electronics question – LED resistors, boosts welcome
Did you get an answer? The basic idea is to use Ohm's law with a twist. The voltage drop across the LED is constant and depends on the color. Say you apply 5V to an LED with a series current limiting resistor, if the LED is green it will drop 2.2V. that leaves 2.8V dropped across the resistor.
in reply to George Albercook

Electronics question – LED resistors, boosts welcome

V=IR, V/I=R if you want 100mA to flow thru the circuit take 2.8/0.1 and you get 28 Ohms.

It is always a good idea to use a current limited power supply for testing.

I'm not an EE so only know enough ot cause trouble. Corrections welcome.

in reply to George Albercook

Electronics question – LED resistors, boosts welcome

phew! Oh yes, thank you for checking and for the thoughful reply.

Many answers in the replies said exactly this (note the post was nearly a year ago...I have since wired it all up, completed the artwork and exhibited it at three venues!) but much appreciated for taking the time.

in reply to Fionnáin

Electronics question – LED resistors, boosts welcome
Thank you for your kind reply. I'm still very new to Mastodon. It seems that the the number next to the reply arrow is not the number of replies. But if I touch the test of your post I'm taken to a different view where I see all the replies. That is confusing.
in reply to George Albercook

Electronics question – LED resistors, boosts welcome

yes there are some things here that take some getting used to, and a few small bugs because Mastodon is non-commercial and it is up to users, not teams of paid testers, to report errors.

There are also other reasons you might not see replies on an old post. Eg:

1) Many people automatically delete old posts
2) Many people reply privately
3) Some people's instances may not be 'federated' with your instance

in reply to Fionnáin

Electronics question – LED resistors, boosts welcome

the third example above is one that can be hard to understand as a new user, but becomes easier over time. There are plenty of explanations online about federation but I learned mostly by just interacting on here and picking up meaning slowly.

And welcome to Mastodon!

in reply to Fionnáin

Electronics question – LED resistors, boosts welcome
interesting. So I don't see any replies. Do you know why?


The Wednesday Adams series on Netflix looks dope.

Can't wait for it to be canceled regardless of the high praises by a CEO drunk out of his mind. And replaced by yet another cooking contest show for people with no personality.

"Self-Hosting Is the Ultimate Privacy Power Move"

When you use a third-party service for your needs, whatever those needs may be, you’re always taking on a certain degree of privacy risk.

howtogeek.com/846979/heres-why…

in reply to Nextcloud 📱☁️💻

I don't see many tutorials on securing your self-hosted Nextcloud service. I love next cloud but I'm always wondering if I'm safe running in on the internet wasteland.
in reply to Nextcloud 📱☁️💻

I can definitely see the appeal to self hosting a lot of things, maybe if I ever have enough space for that sort of thing I'll look into it again some day.

If it works well on the Steam deck does this mean it will usually work well on desktop Linux with Steam?


You may think it’s very lonely to be a crew of manikins aboard a spaceship flying to the Moon, but the reality is that we managed to fit a lot of companions into the @NASA_Orion spacecraft!

…Snoopy, get out of the way. You’re floating right in front of my view of the Moon.

Ready for launch 🔦

The Lunar Flashlight mission is set to launch no earlier than Nov. 30. Once it's in orbit around the Moon, this briefcase-size satellite will use lasers to light up dark craters as it hunts for hidden water ice.

Even though @NASA_Orion is uncrewed, that doesn't mean the spacecraft is empty.
