🛰️ Starcarta Update 1.4!

✨ New:
- Star focus

Stars in multiple systems can be far apart making it difficult to zoom in. Now by clicking on a Star’s name, you can zoom in on that star and its planets. Clicking the Star’s name again toggles you back to the the System.

Recently, JWT studied Trappist-1e’s atmosphere ruling out a Venus or Mars-like atmosphere but leaving water possible for future studies. science.nasa.gov/missions/web... Check it at starcarta.app/o/jkSG - you can also see how all of the 7 discovered planets are less than 1 au from Trappist-1

1 AU Graph
Orbits can be hard to compare. Toggle a dotted circle at Earth’s orbit (1 AU) around stars to make comparisons easier. Helps show scale since stars give few clues about size. (4/4) Try it out at starcarta.app

Tag Highlighting!
Click a Tag to highlight all Star Systems linked to it, then click a System name to travel there. Get a good perspective of the set in 3D space around us. (3/4)

First: Tags!
Add a tag to any star system to categorize it by feature (Gas Planets, Rings), multiplicity (Binary, Triple), or movie franchise (Alien, Star Trek, Dune). Anything you like! (2/4)

The Habitable Zone of our solar system, which is between 0.99au & 1.70au includes both Earth & Mars (even though Mars is too small to hold enough atmosphere) but excludes the runaway greenhouse Venus. Interestingly, you can see how the Earth is just balanced on the inner edge.

GL581 is a low-activity, stable M-class star. It has 2 candidate planets well positioned in their HZ, GL581 b & GL581 c. GL581 b is a 6 Me super-earth, zipping around every 5 days, while GL581 c is a more reasonable 2 Me planet, taking 13 days to complete an orbit. starcarta.app/o/JdJCb #astronomy
