Pic Astronomers scanning the sky for potentially hazardous space rocks have discovered a first – a presumed trojan asteroid around Jupiter that is looking increasingly like a comet.
Liquid fuel, and free fall. Here’s hoping the engine lights!
Not entirely correct as there were three crewed Shenzhou missions in the last ten years.

Astronomers have finally found hard-to-detect visible matter scattered across space, left over from the Big Bang, after searching for nearly thirty years, according to a study published in Nature.

Macquart isn’t referring to dark energy or dark matter. Instead, the study deals with baryonic matter, which is normal stuff made of protons and neutrons. The computer or device you’re using right now to read this is made up of it. This matter should also be out there in space, too, lingering between the galaxies and stars, but it’s missing, or rather, boffins couldn’t find it. The material is spread incredibly thinly across the void, making it difficult to detect.
Like the gas giants in the outer region of the Solar System, Mars may have been circled by a ring of debris over three billion years ago.
Astronomers from the SETI Institute and Purdue University have spotted tantalizing signs that the red, rocky planet once supported a ring system. The clues lie in its two potato-shaped moons, Deimos and Phobos.
The ASTERIA CubeSat, launched from the International Space Station into low-Earth orbit in 2017, has become the smallest satellite to successfully detect an exoplanet.
And that’s thanks to the scientists and engineers who managed to squeeze hardware capable of measuring tiny fluctuations of light from a star down to a CubeSat form factor. The 10cm × 20cm × 30cm bird managed to pick up 55 Cancri e, some 40 light years away and a celestial body that was known though had never been detected by such relatively lightweight kit before.
Japan’s space agency (JAXA) has announced plans to test a self-destructing satellite in the hope of commercialising the technology so the proliferating fleet of low-orbit kit doesn’t become junk.
Titan, the only known moon in the Solar System with an atmosphere, is drifting away from Saturn at a rate a hundred times faster than previous estimates, according to the latest research published in Nature Astronomy on Monday.
