Orbiting two suns: The science behind Tatooine and 'Obi-Wan Kenobi'

Humans are arrogant. It's not necessarily our fault, we can only see the universe through our own eyes, so we tend to assume that the way we do things is the best or only way to do them.

When it comes to Tatooine, we do know a little bit about the star system. We know that the planet is circumbinary, meaning it orbits both stars at the same time.

Mercury has returned to the morning sky, just peeking over the eastern horizon before being washed out by the glare of the rising sun. Mercury's return offers us an even more interesting view of the already excellent morning planet lineup.

Super-Earth Found Orbiting Nearby Red Dwarf Ross 508 | Sci-News.com

Using the radial velocity technique, astronomers have discovered a super-Earth exoplanet orbiting near the inner edge of the habitable zone of the cool M-dwarf Ross 508.

"Exoplanets are known to orbit various types of stars such as solar-type stars, low-mass M-dwarfs (red dwarf stars), evolved stars, and stellar remnants," said Subaru Telescope astronomer Hiroki Harakawa and colleagues.

Ground-breaking number of brown dwarfs discovered

However, despite remarkable efforts in the development of new observing technologies and image processing techniques, direct detections of brown dwarf companions to stars have remained rather sparse, with only around 40 systems imaged in almost three decades of searches.

"Wide-orbit brown dwarf companions are rare to start with, and detecting them directly poses huge technical challenges since the host stars completely blind our telescopes," says Mariangela Bonavita. Most surveys conducted so far have been blindly targeting random stars from young clusters.

This Planet Rains Molten Glass And Has Wind Faster Than The Speed Of Sound

Due to the nature of these two detection methods, the most likely planets to be found are large and orbit close to their parent star. This is because massive planets affect the wobble of their star more, making it easier to detect Doppler shifts.

The planet in question is HD 189733 b (per the database Open Expoplanet Catalogue ) and it orbits a small, nearby star in the Vulpecula constellation (per Sea and Sky ).
