A comet from another star system is carrying water unlike anything astronomers have ever measured in our cosmic neighborhood. Observations published in June 2026 in Nature Astronomy reveal that interstellar comet 3I/ATLAS contains more than 40 times the concentration of deuterium,

Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

The Kuiper Belt object Altjira was thought to be a binary, but closer analysis suggests that it is highly likely to be a triple system This raises the question of the three-body problem; if Altjira does have three objects, how exactly do they orbit each other?

It comes down to the speed at which these objects were moving during their formation, and the strength with which their constituent particles interlocked. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Researchers have found all five of the essential bases that make up DNA and RNA in samples taken from the asteroid Ryugu. This discovery, published inNature Astronomy on March 16, 2026, challenges the long-held belief that these building blocks of life are unique to Earth.

Already, data collected from hundreds of hours of observation across 57 artificial solar eclipses indicates that the solar wind is moving much faster than predicted, as much as three to four times faster than expected, with recorded velocities of between 250-500 kilometres per second, much faster than the theorized rate of 100 km/s.

No matter your areas of interest, it's likely your newsfeed, whichever one you may use, has been flooded recently with the opinions of so-called Harvard scientists that there's an alien spacecraft heading our way, looking to obliterate us all as soon as ...

Space-based solar power, a long-envisioned technology, is gaining momentum as a crucial solution to meet growing energy demands and achieve decarbonization targets. This technology offers significant benefits, including 24/7 high-intensity sunlight ...
