news Astronomy Evidence status: Peer reviewed · Calculated colours from existing spectra and models
Nearby white dwarfs look white on average, Warwick astronomers calculate, but about 1 in 30 would look yellow or pink, and one known star would look green.

How many moons does Venus have? None, and Mercury has none either. See NASA's moon counts for every planet and why the Sun and tides leave both moonless.

How long does it take to get to each planet? From 94 days to Venus to 12 years for Neptune: real NASA and ESA mission times, Hohmann math and gravity…
news Astronomy Evidence status: Peer reviewed · Observational study of one planet
JWST mapped hot Jupiter WASP-17b's atmosphere angle by angle: the evening edge is about 650 K hotter and puffier than the morning edge. How, and the catch.

How long does it take to get to Mars? About 7 to 10 months. See NASA mission travel times, the Hohmann transfer math, launch windows and crewed trip estimates.
News Astronomy Evidence status: Peer reviewed · Telescope observations
Hubble tracked an immense, evolving decagon-shaped atmospheric wave around Saturn’s south pole, creating a striking counterpart to its northern hexagon.
News Astronomy Evidence status: Peer reviewed · Observational study with forward modelling
Astronomy · Peer reviewed. Star formation fell much faster than the universe’s atomic-hydrogen supply, shifting attention from fuel loss to fuel conversion.
News Astronomy Evidence status: Peer reviewed · Model-based geophysical inference
Sixteen years of spacecraft tracking indicate a much warmer, softer mantle beneath southern Mars, though the temperatures are model-based.
News Astronomy Evidence status: Official announcement · Confirmed mission event
NASA’s Roman Space Telescope launched successfully and is traveling to L2, where it will map billions of galaxies and search for exoplanets.
