What's New in NearLight

1.5.8

July 7, 2026

Look up through a telescope, right where you're standing. The Earth view's new telescope mode lets you observe the real night sky the way an amateur astronomer does: • Planets and moons are now clickable sky targets: pick them, or any star or Messier object, from the new Planets / Stars / Messier list, and the view slews straight to it. • EQ Tracking holds your target centred as the sky rotates, like an equatorial mount. • Manual focus: switch Autofocus off and rack the focus wheel by hand to find the perfect sharp point, every eyepiece change nudges it out, just like the real thing. • Redlight night-vision mode washes the whole app deep red to protect your dark-adapted eyes. • Zoom now reaches 20×, so you can inspect Andromeda and the Messier clusters without an eyepiece. Solar System: real mission physics. • Gravity-assist routes are rebuilt the way NASA plots them: two transfer arcs meeting at Jupiter, bending around the correct side, with live flyby telemetry (approach speed, required bend, periapsis radius). • Better launch windows: the planner tells you when no real slingshot exists and scans 14 years ahead for the next one. • Planet positions now use JPL ephemerides, matching the real sky across centuries. Also in this update • Andromeda now sits the right way up. • Smoother, faster performance and a quicker first load of the Earth view. • Fixes for an iPhone crash and the telescope view in landscape. Clear skies!

Great

A great app that isn't limited to the solar system. It's great fun just letting your imagination run wild.

My Google Earth for Space

I'm not an astronomer, but I just love "playing" with this app, and it never ceases to amaze me because I simply can't imagine these vast scales. The app runs very smoothly and stably. Most of all, I love the interactive 3D view of the Milky Way and the black hole.

Nearlight Rez.

NearLight is an outstanding app for anyone interested in space exploration, relativity, and realistic science fiction. Its combination of engaging visuals, scientific accuracy, and interactive simulations makes it one of the most compelling applications in this field. For astronomy and physics enthusiasts, it comes highly recommended

Can people work without texting AI today? :) Thank you very much nonethless SpaceConq, appreciate it strongly!

Cool one

Thought it’s more like a game but it’s hardcore physics behind it. Love it so far!

Response from developer

Since it´s physics based, gamification wasn´t really on my mind :) Thank you!

FAQ

What is NearLight?

NearLight is a 3D space simulator that allows you to explore nearby star systems, visualize interstellar distances, and calculate travel times using both classic and relativistic physics. It's designed for astronomy fans, sci-fi lovers, and physics enthusiasts.

What kind of physics does NearLight use?

NearLight utilizes both classic physics and relativistic physics, including concepts like time dilation and the Lorentz factor. You can see how space travel changes when relativity is considered, especially near massive objects like black holes.

Can I explore our Solar System in NearLight?

Yes, NearLight features a Kepler-accurate 3D scene of our Solar System, including the Sun, all 8 planets, and 8 major moons on real JPL orbits. It also includes a day/night Earth, Saturn's rings, and a textured sky.

How many stars can I explore in NearLight?

NearLight allows you to explore over 8,000 real stars within 1,000 light-years of your location. You can search and inspect these stars, including their known names, distances, and stellar data.

Does NearLight have ads?

No, NearLight does not contain advertisements. It is a paid application with no ads to disrupt your exploration experience.

What devices does NearLight support?

NearLight is supported on Mac, iPhone, and iPad devices, allowing for exploration across multiple Apple platforms.
