  • Astronomers have discovered a fourth giant planet around a distant star, further strengthening the resemblances between this planetary system and our own. The study provides new information about the nature and abundance of solar systems and could aid in the search for habitable, Earth-like worlds.

  • A new blacker-than pitch material could help scientists gather hard-to-obtain scientific measurements or observe unseen astronomical objects like Earth-sized planets orbiting distant stars. The technological advancement could thereby aid astrobiologists in the search for habitable, extrasolar worlds.

  • Astronomers have discovered that the number of red dwarf stars in the Universe is likely three times greater than previously thought. Because they are relatively small and dim, astronomers hadn't been able to detect them in galaxies other than our own Milky Way and its
