JWST just mapped the morning weather on a planet 690 light-years away, and the forecast of sand-like clouds exposed a 100-fold bias in how exoplanet atmospheres have been read for more than a decade

In 1970 a Soviet probe became the first object ever to transmit from the surface of another planet, and it lasted barely 23 minutes on Venus before the heat killed it
Constellations
Venus, Jupiter, and Mercury are lining up in the western sky after sunset this week — and a Blue Moon is sliding past Antares — in a run of evening sky events that won't be matched again for years

The Hubble Space Telescope was launched before Google, before the smartphone era, and before digital cameras became normal, and NASA engineers have now reconfigured it to keep observing the universe on a single working gyroscope after 35 years aloft.

The Wow! Signal lasted 72 seconds in 1977, has never been detected again, and remains the most compelling unexplained candidate in the history of the search for extraterrestrial intelligence.

Voyager 1 is still transmitting from more than 24 billion kilometres away, but in 2024 NASA had to repair it by remotely moving pieces of 46-year-old code around a failed memory chip — a software patch sent into interstellar space and confirmed nearly two days later.

When Soviet cosmonaut Sergei Krikalev launched to Mir in May 1991, the country that sent him was still the USSR; by the time he returned in March 1992 it no longer existed, his home city of Leningrad had become Saint Petersburg, and even the spaceport that launched him — Baikonur — was now inside newly independent Kazakhstan, forcing Russia to renegotiate access to the machinery of its own space program

A joint European-Chinese satellite just went up on Vega-C, and the images it returns could change how scientists understand Earth’s magnetic shield

SpaceX’s IPO filing isn’t just about rockets: the prospectus points to an AI infrastructure pivot that could reshape how investors value the company

The satellite industry is betting on multi-orbit resilience, but a San Francisco startup says the real future may be switching between LEO networks instead

The FCC just gave Lynk and Anterix a small 900 MHz test from orbit, and it could redraw how utility networks reach remote America

The Hubble Space Telescope's main mirror was ground to the wrong shape by 2.2 micrometers, about one-fiftieth the width of a human hair, and the error was only caught after launch because the device used to verify the mirror on the ground had itself been built wrong

The Pioneer 10 and 11 spacecraft were found to be decelerating slightly more than gravity could explain, and for thirty years physicists wondered if Newton was wrong before realizing in 2012 that the answer was the probes' own waste heat gently pushing them backward at a billionth of Earth's gravity.

A comet drifted alone between the stars for up to 11 billion years before entering our solar system last year — and the water inside it is unlike anything scientists have ever seen in our own
