Timelapse of interstellar comet 3I/ATLAS +background stars in Ophiuchus from 16x1-minute exposures last night (1m Jacobus Kapteyn telescope on La Palma through SARA remote ops). Unlike bound outer solar-system objects, most of its apparent motion is intrinsic, not reflex of Earth orbital motion.🔭☄️

Thank for your sharing that Alabama perspective on the national news. My brother met his beautiful bride at the University of Alabama.

Every living NASA science chief unites in opposition to unprecedented… The entire past leadership of NASA’s science activities have released a joint statement condemning the proposed 47% cuts proposed to the agency’s science…

Thank you, @planetarysociety.bsky.social for reminding #Congress of the incalculable value of #NASAScience

Scientists behind threatened NASA missions explain what’s at stake Here is what they have to say, in their own words.

What’s really at stake if NASA’s science budget gets slashed and entire science missions are canceled?

We asked the scientists leading those missions, and their stories reveal what we all stand to lose.

Here’s what they told us: www.planetary.org/articles/sci...

Traditional, Christian and Pagan, festivals marked the seasons and calendar, encoding ancient sky lore. We should not lose that connection to either our cultural traditions or the natural world.

For those who celebrate, may you draw strength and vitality from the summer solstice.

Solstice from Latin sōlstitium via old French

sōl (sun) + participial stem of sistĕre = stand still

Einen schönen Tag der Arbeit wünsche ich Euch.

#LaborDay in Austria falls on a #crossquarter day, roughly halfway between #vernalequinox and #summersolstice, as the days continue to lengthen.

I'll be with Mike Kurtz giving @scixcommunity.bsky.social
demos all day in the #NASA booth.

Come learn how our #digitallibrary supports your #openscience and transforms how you explore #science literature (& #data & #software)

Looking forward to working with you to promote @scixcommunity.bsky.social and #openscience

I'm excited to be giving my first #NASA hyperwall talks at #EGU25 and helping #earthscience researchers use @scixcommunity.bsky.social

For those who celebrate, may your heart join nature in singing the joy of #spring this #vernalequinox.

Consider our #seasons with #Earth tilted ~23.4 deg,
imagine seasons on #Uranus tilted ~82.2 deg.

📢 SciX seeks a heliophysics researcher to connect SciX with their community (2-year term). For more info: s.si.edu/4kD7FSo

I made a custom GPT that connects to the ADS/SciX API to help with literature searches and finding relevant earth and space science info that we have in our digital library. Try to break it and/or tell me if it’s working for how you’d use it! 🤖 📚 🚀
