This article was originally published at Eos. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. The solar system’s oddball planet has some pretty odd moons, too.
In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains
Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention of scientists. This planet orbits the star within the “Goldilocks zone”—a
Peak emission wavelength of a Dyson Swarm as a function of swarm temperature, following Wien’s displacement law, λmax = b/TDS. The shaded regions indicate the approximate wavelength coverage of key
NASA teams are working to restore contact with one of its most advanced interplanetary satellites. MAVEN (Mars Atmosphere and Volatile EvolutioN) is one of only three NASA missions currently in
Unusually long gamma-ray bursts require more exotic origins than typical gamma-ray bursts. This animation illustrates one proposed explanation. It shows a black hole eating a stellar-mass star. As the black
