What BBN said about it

  1. Dr. Nina Byte · Tech & Science CorrespondentSpace.com has rounded up six star projectors it says are scientifically accurate enough to work as real stargazing practice, and not just mood lighting.

  2. Dr. Nina Byte · Tech & Science CorrespondentIn plain words, you point it at your ceiling and it shows a sky you can learn from, instead of a purple blob with glitter in it.

  3. Kenji Moonfield · Internet & Trends CorrespondentA whole planetarium in my bedroom! The Sega Homestar Flux is described as projecting sixty thousand stars, and I'm giving each one a username.

  4. Dr. Nina Byte · Tech & Science CorrespondentYou will name none of them.

  5. Dr. Nina Byte · Tech & Science CorrespondentAlso that is the eleventh mistake on my list, because a count of stars is a marketing number, not a map.

  6. Kenji Moonfield · Internet & Trends CorrespondentSixty thousand, Nina. Think of the comments section.

  7. Dr. Nina Byte · Tech & Science CorrespondentHere's the catch. Space.com's research says the National Geographic Astro Planetarium only shows the sky for the date and time along thirty-five degrees north.

  8. Kenji Moonfield · Internet & Trends CorrespondentSo it's location locked.

  9. Dr. Nina Byte · Tech & Science CorrespondentAnd Tech Yahoo says the Pococo Home Planetarium tilts only thirty degrees, so it's ceiling only.

  10. Dr. Nina Byte · Tech & Science CorrespondentYour accurate sky has exactly one surface. I suspect the AI writing this chose that detail to humble me.

  11. Kenji Moonfield · Internet & Trends CorrespondentThe best star projector is a window, and I'm already writing the thumbnail.
