Pulsars emit deadly radiation, disintegrating DNA and making them dangerous. Surprisingly, some have planets orbiting them, defying current theories.
The TESS space telescope was launched on April 18, 2018, sitting atop a Space X Falcon 9 rocket. This telescope, which is short for the Transiting Exoplanet Survey Satellite, is designed to scan the night sky in search of one thing — exoplanets, or potentially habitable planets outside of our solar system.
Observing starlight variations, scientists confirmed HD 189733 b as a blue planet, shedding light on exoplanet properties through host star analysis.
Astronomers from the European Southern Observatory have discovered the nearest extrasolar planet to date, in the Alpha Centauri star system 4.3 light years away. The system is composed of three stars -- two stars similar in size to our Sun orbiting close to each other and…
An exoplanet that orbits around two stars, known as a circumbinary planet, has recently been discovered by astronomers using the Kepler space telescope. The planet dubbed Kepler-16b has been compared to the planet Tatooine from Star Wars, due to the fact that it has two Suns in its sky.
The following infographic is a comparison of three alien star systems with our own solar system. It shows the distance at which all the known planets orbit around their stars. As of August 10, 2011, 573 extra-solar planets have been identified, but so far the three systems illustrated below are the record holders for having the most planets.
