“Terminator habitability” not in the realm of sci-fi, says research
Much like the Moon is to Earth, many planets are tidally locked to their suns, meaning that the planet takes the same amount of time to spin on its axis as it does to orbit the sun
Astronomers spot new tiny moons around Neptune and Uranus
Astronomers have found three previously unknown moons in our solar system, two additional moons circling Neptune and one around Uranus.
The distant tiny moons were spotted using powerful land-based telescopes in Hawaii and Chile, and announced Friday by the International Astronomical Union's Minor Planet Center.
The latest tally puts Neptune at 16 known moons and Uranus at 28.

Astronomers identify most reflective exoplanet
A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System, astronomers said yesterday.
This strange world, which is more than 260 light years from Earth, reflects 80 percent of the light from its host star, according to new observations from Europe's exoplanet-probing Cheops space telescope.

Why have one ‘impossible’ ring around your world when you could have two?
Earlier this year, astronomers announced that a tiny world beyond Neptune with a diameter about one-third that of Earth's moon possessed a Saturn-like ring that should not be there. It now turns out that there are two such "impossible" rings.
