There’s less Mercury in the system. Scientists found that Mercury, the solar system’s smallest planet, is shrinking far…
Andromeda is visible from 2.5 million light-years because the light of hundreds of billions of stars blends together. But an Earth-like planet there would be roughly ten billion times fainter than its own star and separated from it by only about 1.3 microarcseconds—far beyond the direct-imaging ability of any existing telescope.
Andromeda can be found without a telescope under a sufficiently dark sky, even though its light has travelled…
A molecular-hydrogen cloud only 300 light-years away spans roughly 40 full-Moon widths across our sky, yet astronomers did not identify it until 2025. Named Eos, it escaped conventional surveys because they search for molecular hydrogen indirectly through carbon monoxide—and almost all of Eos is CO-dark.
One of the nearest molecular clouds to the Sun hid across a patch of sky about 20 degrees…
