Dating of solar system how

That’s despite the fact that they are all so close to it – each of them sitting nearer to the star than Mercury, the planet in our solar system that orbits closest to the Sun.

“The spectacle would be beautiful,” said Amaury Triaud, one of the scientists involved in the research.

Nasa's Hubble Space Telescope is already being used to search for atmospheres around the planets.

Future telescopes, including the the European Extremely Large Telescope and James Webb Space Telescope, may be powerful enough to detect markers of life such as oxygen in the atmospheres of exoplanets. Since then, astronomers have detected more than 3,500 of the worlds, distributed across 2,675 star systems.

After New Horizons passes Pluto it will travel into the mysterious Kuiper Belt or Third Zone before eventually leaving the Solar System altogether, making Tombaugh's ashes the first to journey so far. The craft was sent out with the intention of making contact with intelligent life.

It would be fitting if Tombaugh’s ashes were eventually found by an extraterrestrial race.

That’s because roughly the same amount of energy would be coming from the star as warms our Earth – but it does so infrared.

Despite that relative darkness, everything would still feel warm, the researchers said.

Tombaugh (1906-1997)." Previously an amateur astronomer, he had been hired to help find a planet beyond Neptune.

He also credited of discovering 14 other asteroids.

That works by watching out for when a planet passes, or transits, in front of its host star – blocking out a small amount of light, allowing us to see the planet and learn about its size.

Scientists first found the star TRAPPIST-1 in 2010, after monitoring the smallest stars close to the Sun.
