In July 2026, a Falcon 9 carried 21 more satellites into polar orbit for the Pentagon's Golden Dome mesh network, a constellation designed to be too numerous to destroy, yet the laser links meant to weave those satellites into a single battle network are still switched off in orbit, months behind schedule

The North Star is not the brightest star in the sky — not even close: Polaris ranks around 48th, far outshone by Sirius and dozens of others; what makes it special is only that it sits almost over the North Pole

Arno Penzias and Robert Wilson spent months at Bell Labs in New Jersey convinced the faint hiss in their antenna was a fault — pigeons, droppings, loose rivets, all ruled out — before a Princeton physicist told them it was the oldest light in the universe, the afterglow of the Big Bang.

By mid-2026 a single company, SpaceX, had more than 10,000 Starlink satellites circling the Earth — roughly two of every three active satellites in orbit now belong to one man's network

In July 1969, weeks before Apollo 11 launched, a NASA engineer named Jack Garman handwrote a list of every alarm code the Apollo Guidance Computer could throw and placed it under the plexiglass on his console — and when Margaret Hamilton's software triggered a 1202 alarm during the lunar descent with roughly 1,800 metres to go, that scrap of paper kept Mission Control from aborting the landing.

When Italian and German researchers modeled a square-meter array of 1,482 neodymium magnets, the simulation showed roughly a fifth of incoming low-energy solar protons being deflected — suggesting a potential way for deep-space crews to reduce some of the mass they currently carry for radiation shielding.

Nearly a millennium ago sky-watchers recorded a new star so bright it was visible in daylight for weeks, and Hubble has now traced how far its remnant, the Crab Nebula, has expanded since — a thousand-year-old explosion still visibly unfolding

James Webb has caught at least five galaxies colliding about 800 million years after the Big Bang, flinging heavy elements out into space far earlier than any model predicted — evidence the early universe was already messy and mature when it should still have been simple

On July 10, 2026, China caught the falling first stage of a Long March 10B in a net strung across a ship at sea, becoming only the second nation ever to recover an orbital-class booster, and it now plans to fly the very same stage again before the year is out

In May 1986, Leonid Kizim and Vladimir Solovyov left the newly opened Mir, crossed 2,500 kilometres to Salyut 7, and returned carrying 350 to 400 kilograms of instruments — the only human voyage ever made from one space station to another

In July 2026, German rocket startup Isar Aerospace signed a Nova Scotia launch-site agreement whose disclosed quarterly fee schedule totals US$112.5 million before per-launch charges, with plans for up to 40 flights a year from a Spectrum rocket that has never reached orbit

In 2026, the FCC authorized radio operations for Reflect Orbital’s first 18-metre space mirror, a single demonstration for a proposed 50,000-satellite system that one astronomy model says could raise the natural night-sky background by 200% to 300%

We tend to assume life needs a star to begin, but a 2025 study found that some moons carried into deep space by planets expelled during supernova explosions could preserve subsurface oceans for billions of years — heated not by sunlight, but by the repeated gravitational flexing of their orbits.

SpaceX has asked to place 100,000 Gen3 satellites into 20 orbital shells split between 323–327.5 and 473–477.5 kilometers above Earth, each weighing up to 2,500 kilograms — more than 200 million kilograms of spacecraft before a single launch vehicle or drop of propellant is counted
