Free Cosmic Observatory — Live Universe Data You Won't Find Elsewhere

This free cosmic observatory dashboard brings together real-time data from multiple space agencies and scientific sources into a single, visually stunning interface. Unlike static astronomy websites or AI chatbots that can only tell you general facts, this tool shows you what is actually happening in space right now — from asteroids passing near Earth today to the exact position of the International Space Station overhead and the precise distance of Voyager 1 from our planet at this very second.

Asteroids Near Earth Today — Live NASA NEO Data

The asteroid tracker uses NASA's NeoWs feed (built on CNEOS orbit solutions) to display every asteroid making a close approach to Earth today, with summary stats, filters and the local time of each closest approach, plus JPL's close-approach database for every known pass within five lunar distances over the next 60 days. For each object you can see the estimated diameter in metres, approach velocity in kilometres per second, miss distance in both lunar distances and kilometres, and whether NASA classifies it as a potentially hazardous asteroid. This is the same data used by planetary defence scientists — most people never see it presented this clearly. Search engines rarely surface this level of detail for queries like "asteroids near earth today" or "nearest asteroid to earth right now."

ISS Tracker, Voyager Distance & Cosmic Calculators

The ISS tracker shows the International Space Station's current position on a world map with the live day/night terminator, its past and next ground track (computed with the SGP4 orbit model from the latest NORAD orbital elements), live altitude and speed, and whether the station is in sunlight. Share your location and it predicts ISS passes over you for the next three days, flagging the ones you can actually see with the naked eye. A live crew panel shows everyone in orbit right now. The Voyager tracker anchors both probes to published NASA/JPL positions — including Voyager 1 becoming the first spacecraft one light-day from Earth on November 18, 2026 — and the Moon and planets panel computes tonight's Moon phase and the live distance to every planet. The light speed calculator shows how far a photon has traveled since you opened the page, with comparisons to Earth-Moon distance, Earth circumference, and Earth-Sun distance. The planetary weight calculator lets you see your weight on all eight planets plus the Moon, Pluto, and the Sun.

Free — No Signup, No Ads, No Data Collection

This cosmic observatory is completely free to use with no registration required. It runs entirely in your browser using public NASA APIs and calculated astrophysical data. Every counter ticks in real time — the universe age, Voyager distances, light travel, and cosmic process counters all update live. It is one of the free browser-based tools available at jasperbernaers.com.

Asteroids, the ISS and deep space, explained

Cosmic Observatory pulls live space data into one dashboard: near-Earth asteroids from NASA, the position and passes of the International Space Station, the people currently in orbit, the Moon’s phase and the distance of Voyager 1. Below: what the numbers mean and where each one comes from.

How many asteroids pass near Earth every day?

NASA's NeoWs feed typically lists a few to a few dozen asteroids making close approaches on a given day. Most are small (under 50 metres) and pass millions of kilometres away. Small asteroids slip closer than the Moon (384,400 km) many times per year — the 60-day table shows every known pass within 5 lunar distances. The dashboard shows all objects tracked for today with their exact miss distances.

What is a potentially hazardous asteroid?

NASA classifies an asteroid as potentially hazardous (PHA) if it is roughly 140 metres or larger (absolute magnitude H ≤ 22) AND its orbit comes within 0.05 astronomical units (about 7.5 million km) of Earth's orbit. More than 40,000 near-Earth asteroids were known by late 2025 (ESA), and a few thousand of them are PHAs. Being classified as "potentially hazardous" does not mean an impact is expected — it means the orbit warrants careful monitoring.

Where is the ISS right now?

The ISS orbits Earth roughly 400–420 km up at about 27,600 km/h, completing an orbit every 92–93 minutes — about 15.5 times per day. The dashboard shows its live altitude and speed and updates the position every 5 seconds (wheretheiss.at, with an SGP4 model as backup). Press Locate me to get pass times for your location. The station is visible from the ground as a bright moving "star" and can be seen from most locations on Earth at some point during the week.

How far is Voyager 1 from Earth?

Voyager 1 is about 25.8–25.9 billion kilometres from Earth in autumn 2026 and moving away at roughly 17 km/s (about 61,000 km/h). NASA calculates it reaches one light-day (25,902,068,356 km) from Earth on November 18, 2026 — after that a radio signal takes more than 24 hours each way. Voyager 1 entered interstellar space in August 2012, crossing the heliopause — the boundary where the Sun's influence ends.

When can I see the ISS from where I live?

Press Locate me in the ISS panel. The page predicts every pass above 10° for the next 3 days using the SGP4 orbit model and marks the visible ones — when the station is lit by the Sun while your sky is dark, usually shortly after sunset or before sunrise. Look for a bright, steady, fast-moving "star" with no blinking lights; a pass lasts a few minutes.

How many people are in space right now?

The People in Orbit panel lists everyone currently in space, grouped by spacecraft — usually the ISS and China's Tiangong station — with their role, agency and how long they have been up there.

What is the Moon phase tonight?

The Moon & Planets panel draws the current phase, the illuminated percentage and the Moon's age, and gives the next full and new moon in your local time, calculated with Jean Meeus' algorithms (accurate to a few minutes).

How old is the universe?

The universe is approximately 13.787 billion years old, based on measurements of the cosmic microwave background radiation by the Planck satellite. This age is known to a precision of about 20 million years. The dashboard displays this age as a live counter, ticking forward in real time to illustrate the ongoing passage of cosmic time.

Is the data on this dashboard real?

Yes. Today's asteroids come from NASA NeoWs (api.nasa.gov) and upcoming passes from JPL's close-approach API. The ISS position comes from wheretheiss.at; ground tracks and pass times are computed in your browser with SGP4 from NORAD orbital elements. Moon phases, planet distances and Voyager distances are calculated from published elements and positions. The cosmic counters use published rates; the star-birth counter is an order-of-magnitude estimate and is labelled as such.
