Today

What the sky is doing in the next twenty-four hours: the Moon's phase if it turns tonight, any planet reaching opposition, a shower at its peak, an eclipse, a launch.

Times are UTC throughout, because an instant is the same everywhere and a local rendering would hide which day an event actually falls on for you. Nothing here knows or asks where you are. Every computed instant carries an uncertainty, and most of those are measurements rather than estimates: every build checks the lunar phases against NASA's own published table, the equinoxes, solstices and Earth's apsides against the US Naval Observatory's, and the planetary positions the remaining events are derived from against JPL Horizons. The Moon's perigee and apogee are the one family with no external table to check against, and their cards say so.

One event

  • Soyuz 2.1b | Progress MS-35 (96P)

    Planned

    Progress MS-35 (96P). A planned launch, not a fixed one: the time shown is the provider's No Earlier Than date, known to the second. Last confirmed by the provider 7 days ago.

    How exact: Planned dates move, routinely by weeks. This one is currently held to the minute, which usually means it is close and confirmed.

    Where this date comes from

    A date somebody intends to meet. Planned dates move, often by months. The timestamp of the last confirmation is shown so you can judge how much the date is worth.

    Source: Launch Library 2 (The Space Devs) — a community-maintained aggregator of operator announcements, not an agency schedule (last confirmed 2026-09-09T15:44:41.000Z)

    Uncertainty: Planned dates move, routinely by weeks. This one is currently held to the minute, which usually means it is close and confirmed.

    Where it applies: Lifts off from 31/6, Baikonur Cosmodrome, Republic of Kazakhstan. Whether it is visible to you depends entirely on where you are relative to the site and the trajectory.

Four kinds of date

Computed
Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.
Published prediction
Taken from an authority's own published prediction. AsteriaStar reproduces it and links the document; it does not recompute it.
Annual forecast
Recurs every year at approximately the same point in Earth's orbit. The date shown is the expected one; the exact hour and the strength vary from year to year.
Planned
A date somebody intends to meet. Planned dates move, often by months. The timestamp of the last confirmation is shown so you can judge how much the date is worth.

Take this away as a calendar file: subscribe or download the next year of events, or read it as JSON from the Open Data API. Both carry the basis, the method or source, and the uncertainty for every entry.

Solar eclipses of the twenty-first century from NASA Eclipse Web Site, fetched from https://eclipse.gsfc.nasa.gov/SEcat5/SE2001-2100.html. The catalogue was computed once and published in 2007. A week is not a compromise between freshness and load — there is no freshness to trade, and re-parsing two hundred and twenty-four eclipses on every page view would be waste with no upside.

Circumstances of GREATEST eclipse only: the instant, the type, the Saros series, gamma, the magnitude, and the point on Earth the shadow axis passes closest to. It does not say what an eclipse looks like from any particular place, and neither does AsteriaStar — local circumstances need the Besselian elements, which NASA publishes separately and which are not read here.

Circumstances of greatest eclipse and the published durations of the penumbral, partial and total phases. Contact times for a specific location are not in the table and are not derived here.

Source file: https://ll.thespacedevs.com/2.2.0/launch/upcoming/?limit=40&mode=list

Upcoming orbital launches from Launch Library 2, fetched from https://ll.thespacedevs.com/2.2.0/launch/upcoming/?limit=40&mode=list. The provider allows fifteen requests an hour. Thirty minutes puts AsteriaStar at two, leaving the rest of the allowance for everyone else, and a launch schedule does not change meaningfully inside half an hour — when it does change, it changes by days.

Intentions, not appointments. Every date is a No Earlier Than value whose precision the provider states explicitly, from the second down to the year, and which moves without notice. The feed is an aggregation of operator announcements maintained by volunteers, not a schedule published by any agency.
