China flies a new reusable rocket as its commercial push accelerates
The maiden flight of the Long March 12B on June 1 marks another step in China's drive toward reusable launchers — and another entrant in an increasingly crowded global market for cheap access to orbit.

Missions
The largest planetary spacecraft NASA ever built is bound for an ocean world
Europa Clipper, launched in 2024, is cruising toward a 2030 arrival at Jupiter, where it will make nearly 50 flybys of the icy moon Europa to judge whether its hidden ocean could support life.

What to watch in the June 2026 sky: a planet parade and a vanishing Venus
June brings the two brightest planets together at dusk, a Moon that briefly hides Venus, the summer solstice, and the long, deep-sky nights that follow. Here's what to look for and when.

Missions
Fifteen years on, Juno is still rewriting Jupiter
NASA's Juno spacecraft, now in extended operations, made a close pass of the small moon Thebe in May — the latest in a mission that has overturned much of what we thought we knew about the giant planet.

Astronomy
After 50 years, astronomers catch our galaxy's black hole exhaling
Sagittarius A* is a famously quiet black hole, but new ALMA observations have finally revealed powerful winds streaming from it — the outflow astronomers spent half a century hunting for.

Astronomy
The most massive black hole pair ever found is hiding in a starless void
Two ultramassive black holes totalling roughly 60 billion solar masses sit at the heart of a distant galaxy, spiralling toward a merger that would create one of the largest black holes known.

Science & Discovery
Saturn now has 285 moons — and the count keeps climbing
A 2026 batch of discoveries pushed Saturn's moon tally to 285 and Jupiter's to 101. The new satellites are tiny, faint, and a sign that a new generation of survey telescopes is just getting started.

Astronomy
Webb peers into a nearby galaxy's heart and settles a 30-year argument
Using a clever masking technique, Webb resolved the dusty core of the Circinus Galaxy and found that almost all its hot-dust glow comes from right beside the black hole — overturning a long-standing assumption.

Astronomy
Webb finds a black hole that grew too big, too fast, too early
Inside a 'little red dot' just 570 million years after the Big Bang, Webb has caught a supermassive black hole feeding voraciously — and far too large for its host galaxy, deepening a puzzle about early cosmic growth.

Why most satellites now fly on a faint blue glow
Electric propulsion trades thrust for efficiency, delivering specific impulses an order of magnitude beyond chemical rockets. It is why modern constellations and deep-space probes do more with far less propellant — and why patience is the price.

Missions
Why Mars landings are an unforgiving engineering problem
Mars has just enough atmosphere to destroy a spacecraft and not enough to land one. Entry, descent, and landing compresses every hard problem in spaceflight into about seven autonomous minutes — and it sets a hard ceiling on how much mass we can put on the surface.

Mars Sample Return: the architecture, and the reckoning
Bringing Perseverance's cached samples to Earth would be the most complex robotic campaign ever flown. Its cost and schedule have forced NASA into a hard rethink — and, as of 2026, the agency is weighing competing architectures rather than committing to one.
