About Aphelion
An independent science blog — accuracy first, clarity second.
What this site is
Aphelion is an independent science blog covering astrophysics, cosmology, and space exploration. Every article is written with two goals: accuracy first, clarity second. We don't dumb things down to the point of being wrong, and we don't leave you lost in jargon.
When something is genuinely settled science, we say so. When something is an active area of debate or an open question — the information paradox, the Hubble tension, the nature of dark energy — we say that too.
What we cover
- Astrophysics fundamentals — black holes, neutron stars, stellar life cycles, gravitational waves
- Exoplanets — detection methods, habitability science, notable discoveries
- Space telescopes and missions — James Webb, Hubble, Chandra, Gaia, Euclid, and what they've found
- Cosmology — the Big Bang, dark matter, dark energy, the large-scale structure of the universe
- Space exploration — robotic missions, planetary science, the solar system
Sources and accuracy
Articles draw on peer-reviewed research, NASA and ESA mission documentation, and reputable science journalism. We cite specific missions, instruments, and survey names (Kepler, TESS, LIGO, JADES, EHT) rather than vague generalities. Where figures are approximations or models, we note it.
If you spot an error, please let us know. We take corrections seriously and update articles when warranted.
