Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.

“The NASA announcement was sudden and caught us by surprise...

For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

The jet power from this relatively close black hole-star system is equivalent to 10,000 suns, an international research team reported Thursday. They also tracked the jet speed: roughly 355 million mph (540 million kph)—half the speed of light.

Located 7,200 light-years away, Cygnus X-1 features not only a black hole—the first one ever identified more than a half-century ago—but a blue supergiant...

The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement for collaboration on the Rapid Apophis Mission for Space Safety (Ramses) to the near-Earth asteroid Apophis.

The agreements were signed on 7 May by ESA Director General Josef Aschbacher and JAXA President Hiroshi Yamakawa at the Embassy of Italy in Berlin, Germany, in the presence of European and Japanese institutional and industrial leadership. The event was hosted in collaboration with the Italian Space Agency (ASI), in light of ESA’s selection of OHB Italia as prime contractor for the Ramses mission.

The move builds on a joint statement from November ...

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, called 2002XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight. Even more puzzling, calculations suggest this atmosphere should vanish within about 1,000 years unless it’s constantly being replenished.

A group of professional and amateur astronomers in Japan has uncovered evidence that a small, distant object in the outer Solar System is surrounded by a thin atmosp...
