NASA Needs Your Help!
NASA is facing severe budget cuts that would cancel missions ready to be launched, put tens of thousands out of a job, and set science back decades. We need your help to ask congress to prevent these ...

#ESAEuclid had a major data release today, I checked one of the regular X-ray AGN in the North Ecliptic Pole to which I happen to know its location, and WHAT ARE THOSE FAINT DIFFUSE EMISSION attached to the galaxy!?

The atomic spectral lines in this app come from the NIST atomic spectroscopy group, which has provided the world with spectroscopic measurements for 120 years.
Today we got word that the federal government is laying off the entire group. 🔭🧪

Tired of wondering which atomic lines are in your spectra? You need:
*whose line is it anyway?* An interactive tool for identifying atomic spectral lines. 🧪🔭 #stars
install:
pip install whoseline

Went to donate my blood, the nurse, while setting my arm up suddenly said "OH MY GOOD LORD" shortly after poking the needle into my arm.
Feeling panicked, I looked at the nurse, who had her earbuds on, expressionlessly saying the next sentence "Someone pour me up a double shot of whiskey..."

Fresh photons from Hubble🔭 last night (well, more than 5 billion years old)! This is a quasar hosted by an extremely luminous , massive galaxy (100 trillion times solar luminosity in infrared, and 100 times more massive than Milky Way).

We had a telecon today, one of our colleagues wasn't there, but her AI assistant joined instead. We might have spent about 1/4 of the time discussing about the note-taking bot instead of having a real meeting🙃
