#Trump’s #budget proposal, though not yet formally submitted to Congress, would eviscerate a long list of #planetary & #astronomical missions, including the next major #NASA #space #telescope & the agency’s goal of bringing samples of #Mars back to Earth to search for signs of ancient life.

NASA’s #astrophysics budget would take a huge hit, dropping from ~$1.5B to $487M. Planetary #science would see a drop from $2.7B to $1.9B. #EarthScience would drop from ~$2.2B to $1.033B.

💡 Did You Know? #2 – How do we measure distances in space? 🌠

The astronomical unit (au) is crucial for mapping our Solar System, but for interstellar distances, light-years and parsecs help us grasp the cosmos' vast scale.

📽️ Watch to explore how astronomers scale distances!

✨ Understanding these distances helps us better comprehend the universe's mysteries. Which cosmic distance amazes you the most?

Here's a #timelapse of the #LEGO #Technic set 42179 #orrery doing a full #astronomical year!

It has accurate turning of the #sun and #earth (day), the earth & #moon system turning around the sun (year), the moon around earth (month) and earths axial tilt (seasons).

It's honestly awesome. One of the most enjoyable technic builds ever. A highly recommended set.

(For the video I added a motor. Out of the box the set is hand-driven which is satisfying in itself as it gives fine control).
