Vera C. Rubin’s research into stars in galaxies led to the modern understanding of dark matter.
Almost everything on Earth is made up of atoms, but where do these fundamental building blocks come from?
To make a truly realistic fake picture of a galaxy, you can model exactly how light particles travel through the atmosphere and telescope to reach its sensor.
Vera Rubin, whose dark-matter discoveries changed astronomy and physics, gets her due with namesake observatory, commemorative quarter
Mars isn’t a bright, fire-engine red, but the iron oxide in its rocks makes it appear redder than other planets, especially from afar.
75 years after Fermi’s paradox, are we any closer to finding extraterrestrial life?
As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s not how it works. Hint: space-time is involved.
In the 19th century, astronomers could see Mars through telescopes, but not clearly. Some used their imaginations to fill in what the blurry images couldn’t convey.
