LHS 1140b: Potentially Habitable Super-Earth Found Nearby Red Dwarf (Super-Terra Scoperta nella Zona Abitable | AstroCaffe Ep.110)




Newly Discovered Exoplanet May be Best Candidate in Search for Signs of Life - Transiting rocky super-Earth found in habitable zone of quiet red dwarf star

An exoplanet orbiting a red dwarf star 40 light-years from Earth may be the new holder of the title "best place to look for signs of life beyond the Solar System". Using ESO's HARPS instrument at La Silla, and other telescopes around the world, an international team of astronomers discovered a "super-Earth" orbiting in the habitable zone around the faint star LHS 1140.

Mission Juno - Juno Probe mission to Jupiter (Mission Juno, la sonda Juno è in arrivo su Giove: diretta NASA) - via @mic_orion



Juno Probe mission to Jupiter

So NASA sent a space probe to study Jupiter in more details. Probe’ is named after goddess Juno, wife of Jupiter.
Juno will study Jupiter’s atmosphere and the interior make up of Jupiter in great detail over 14 months before it plunges in to Jupiter at the end of its mission.

Juno mission should give scientist better understanding how Jupiter came to being and confirm some of the planet formation theories.

Jupiter is the largest planet in our Solar System with mass twice greater than all other planets combined. Jupiter is classed as a gas giant planet, has mass of 318 Earths and radius of nearly 12 Earths. In Jupiter’s volume you can fit over 1000 earths.

Juno was launched on August 5th 2011, using Earth’s gravity assist trajectory the probe was given boost on its voyage to Jupiter.

One of Juno’s mission objectives is to measure the amount of water in Jupiter’s Atmosphere, this would determine where and how Jupiter formed, and provide answer, was Jupiter formed closer to the Sun or was it further out.
Mapping the gravity and the magnetic field of Jupiter will give us some idea if Jupiter has a solid core.

Jupiter’s Magnetic Field is strongest in our solar system, Jupiter experiences Aurora Borealis just as same as Earth, however Jupiter’s Aurora Borealis is 1000 times larger.
