Back to today's update,
one of the new systems updated in this release is the TOI-5789 (aka HD 191785), gained 4 verified planets on it’s primary. Check it, and all the other stars within 200ly of us on starcarta.app/o/CRMjC

Gaia DR4 will have about 500 TB data (www.cosmos.esa.int/web/gaia/dr4...), which about 50x more than DR3. Including a data source for possible rings and disks which so far I’ve been manually setting up
www.cosmos.esa.int/web/gaia/ima...

This would improve all the information and positional data that’s currently used in the app just by changing the intake process. On top of the existing Gaia DR3 (www.cosmos.esa.int/web/gaia#) data, later this year tons more data will be released with the GAIA DR4 drop.

Currently the 3D data is calculated from RA, Dec and dist (or parallax) in the intake batch file I run after downloading the data. However, since each star has a Gaia DR number I’ve been wanting to add another step to my data processing to correct the star’s position with more accurate Gaia data.

It's giving...

There are 1100+ exoplanets within 200 light-years of us, explorable in Starcarta.app

Go check them out 🌌

Space telescopes launched in the past 20 years have been huge for discovering new exoplanets.

Matt O'Dowd also described the major exoplanet detection methods. Here’s one example system discovered with each.

Sirius A & B ✨
The brightest star in the sky. No known planets, but it has a massive, super-hot white dwarf companion roughly Earth-sized: starcarta.app/o/WxDz

The outer ring at 133 AU, is mostly composed of large amount of dust which glows in infrared light. Inside of it are multiple other dust and debris rings, and possibly, protoplanets - still forming 400 million years after Fomalhaut ignited.

Check it, and all the nearby stars out at starcarta.app

A very young star Fomalhaut actually forms a triple system with TW Piscis Austrini, and LP 876-10. It’s fairly close to us at 25 ly. One of it’s standout features is a fairly bright, multipart series of protoplanetary rings around it.

Try it on 83 Leonis, a binary 59 ly away with two planets on the B star: starcarta.app/o/tQlX

I actually have a brief thread on that here bsky.app/profile/stev.... I love when SciFi meets science.

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)

Whelp, time to see how the reboot is coming along then. youtube.com/@undergradst...
