Space Telescope App vs Ishigaki Star Guide

Space Telescope is an astronomy app for people who actually go outside and look up. See what the James Webb Space Telescope is observing right now. Decide whether tonight is worth staying out for. Catch the next visible ISS pass over your own location, and follow the rocket launches coming up. WHAT WEBB IS LOOKING AT, RIGHT NOW Webb's current target, science category, proposal, instruments and scheduled times, refreshed every five minutes while the view is open. Tap through to the proposal or the full observation schedule. A REAL PLAN FOR METEOR NIGHT Most meteor apps hand you a peak date. This one tells you what you will actually see. Set your location and how dark your sky is, and get an honest meteors-per-hour range, the best viewing window, where to look, how much the Moon will wash out, and what 30, 60 or 90 minutes outside is likely to be worth. Two alerts that matter: a heads-up the evening before, and a nudge when your window opens. Cloud cover is not included, so check the weather before you commit. THE ISS, OVER YOUR HOUSE Live position, altitude, velocity and orbit, plus crew, expeditions, dockings and visiting vehicles. Seven days of passes for your location with quality, direction, peak elevation and duration - set a 10-minute alert or drop the pass straight into your calendar. LAUNCH DAY Upcoming launches with live countdowns, status, provider, rocket, pad, launch window and webcast link. One tap for a reminder 15 minutes before liftoff. GALLERIES WORTH SCROLLING Imagery and mission guides for James Webb, Hubble, Chandra, the Nancy Grace Roman Space Telescope, Artemis, Mars and the ISS. Follow Roman's countdown, instruments and journey to L2. Pinch to zoom, save, share, like and comment. Turn on alerts only for the galleries you care about. PICTURE OF THE DAY NASA's Astronomy Picture of the Day, image or video, with the full expert explanation and an optional daily alert.

Hold your phone up to the night sky and the stars in front of you appear on screen, named. A star guide built for one sky: Ishigaki Island, Okinawa. Ishigaki sits at 24.6 degrees north. From here the Southern Cross clears the horizon from winter dawns to spring evenings, a sight never seen from mainland Japan. POINT AND FIND AR mode draws constellation lines and star names over the live camera view, so the screen matches the sky above you; with the camera off it works as a plain chart. Only the constellation at the centre of your view lights up, the others fade back. 5,070 stars down to magnitude 6.0, the naked-eye limit, with lines for all 88 constellations. THE SOUTHERN CROSS, WITH TIMES Search for the Southern Cross: if it is up, an arrow at the edge of the screen guides you as you turn towards it; if not, the time machine jumps to the next time it will be. Check tonight's sky before you go outside. STAR NAMES FROM THE YAEYAMA ISLANDS Antares is Beecha-bushi. The Pleiades are Muri-ga-bushi. Polaris is Ninufa-bushi. The Milky Way is Tingara. Tap a star to see the Yaeyama name beside the modern one, with the story attached. Search "Haimuru-bushi" and the Southern Cross comes up. FIND THE CONSTELLATIONS AND COLLECT THEM Follow the arrow until the constellation is in front of you, hold it there, and tap "Found it" to record it in your book. A guide character then talks about that constellation and suggests a nearby one you have not found yet, arrow ready. Eighty-one constellations are reachable from Ishigaki; the ones that barely clear the horizon, like the Southern Cross at 8 degrees, rank as legendary. Records only count at night at the real current time, so the book holds only what you actually looked at. GUIDED PROGRAMMES, SPOKEN Like a planetarium show, a guided programme walks you through the sky one constellation at a time. "Yaeyama Winter Sky: An Introduction" is free: on nights from December to February it takes you from Orion to the Pleiades, the Winter Triangle and Canopus low over the sea, narrated in the unhurried voice of an island elder, so you can keep looking up. Every description card can also be read aloud. More themed programmes will follow.
