Two things people ask for as soon as they've read their own chart: a way to show it to someone, and other charts to practice on. Astrolas has both, and this short guide covers how they work, what a shared chart shows, and why the celebrity charts on the site are limited to people whose birth data is documented rather than guessed.
Sharing your chart in one click
Cast your chart on the birth chart page โ. Below the wheel there's a Share this chart button. Click it and the site generates a public link of the form astrolas.com/c/your-slug, shows it in a box, and offers a copy button.
The link opens the full chart page for anyone, no account needed: the wheel, the planet and house tables, the aspects, and the patterns. When you paste the link into a messaging app or a social feed, it carries its own preview image, a rendered card of the wheel, so it looks like a chart rather than a bare URL.
The link is public. Anyone with it can open it, and the page shows the birth date, time, and place used to cast the chart, because a chart without its data can't be checked. If you'd rather not publish your birth time, share the chart with people you trust directly rather than posting it, or cast a version with the time rounded to noon and share that with a note that the houses are approximate.
What the shared page shows
The shared page is the same birth chart tool, opened on the shared data. The person you send it to can switch tabs, hover the wheel for aspect details, change the house system, and read every section you can. What they can't do is edit the data or save it as their own profile without an account.
If they have an account, they can enter the same birth data as a profile in their own library and run every other tool on it: transits, solar return, synastry with their own chart. That's the practical use: send a friend your chart, they save the data, and now you can compare.
Sharing a compatibility result
The compatibility tool works the same way. Enter two people, get the result, and the page has its own shareable link. It's the quickest way to send someone a synastry overview: the score, the main cross-aspects, and the link to the full bi-wheel. Neither person needs an account to view it.
The celebrity charts
The site keeps a small set of public charts for well-known people, at addresses like astrolas.com/c/taylor-swift. Each one opens the full chart tool on that person's data, and the blog reads several of them in the case studies. They're there for two reasons.
First, practice. Reading a chart for someone whose life is public is the fastest way to learn what placements look like in practice. You know the output; the chart shows you the input. Steve Jobs's T-square with Mars at the apex, Beyoncรฉ's five-planet stellium in the 6th house, Lady Gaga's Moon-Pluto conjunction in the 10th house: each one is a lesson you can check against a biography.
Second, honesty. Every chart in the set is marked as verified, and the verification standard is a recorded birth time: a birth certificate, a hospital record, or the person's own documented statement. Not a fan estimate, not a "rectified" guess, not a time that appeared on a forum and got copied.
Why birth data quality matters
Most celebrity charts on the internet are wrong, and the way they're wrong is instructive. A birth time gets guessed, published on one site, copied to fifty others, and becomes "known." Then articles get written about the person's rising sign, and the rising sign was never established.
The Rodden rating system, used by serious astrologers and databases, grades birth data: AA for a birth certificate or record, A for the person's own statement or a reliable memory, B for a biography, C for an unreliable source, DD for conflicting sources, X for no time at all. Charts on Astrolas are limited to data that would rate AA or A. That means the set is small, and it means that when a case study says "Capricorn rising," it's a fact about the record rather than a guess dressed up as one.
If a celebrity you're curious about isn't in the set, the honest answer is usually that their birth time isn't documented, and a chart without a birth time has no rising sign and no houses. You can still cast it for noon and read the planets and aspects, which is most of a chart. You just can't read the parts that depend on the hour.
Reading a chart you didn't cast
Whether it's a friend's shared link or a celebrity page, the method is the same as for your own chart, with one difference: you already know how the life turned out, so you can read backwards.
Start with the reading guide's ten steps. Then, for each strong placement, ask "where does this show up in what I know about the person?" The stellium in the 6th and the famously relentless work ethic. The Saturn on the Ascendant and the reserved public manner. The Uranus on the Midheaven and the career nobody predicted.
When a placement doesn't seem to match, that's the interesting case. Sometimes the chart is showing you something the public story leaves out. Sometimes the placement is weaker than you assumed because of orbs or a competing aspect. Either way you learn something about reading charts that a textbook can't teach.
Start with these
Cast and share your own chart first; it's the one you'll learn most from. Then read one of the case studies alongside its chart page, and try to find the placements the article names before you read the explanation.
After a few of those, a shared chart from a friend will be readable in ten minutes. That's when astrology stops being something you look up and starts being something you can do.
