If one Trappist-1 planet has life, it's likely not the only one

  If one Trappist-1 planet has life, it's likely not the only one Scientists model the planets around Trappist-1 and decide that if there's life on one of these planets, there's probably life on more than one of them.A new study did the math on how life could spread around the system of seven Earth-sized planets in close orbit around the ultracool dwarf star Trappist-1, about 40 light years from Earth. The orbits of all seven planets could fit within the distance from our sun to Mercury, a bit like a highly compressed version of our solar system.

NASA discovers NINE earth - like planets and they could contain life. US SPACE agency reveals it's found a record 1,284 new worlds. NASA 's Kepler telescope has just discovered a staggering 1,284 planets with nine potentially Apple unveils brand new 10 .5-inch iPad Pro that packs the feat

That’s why an announcement today from NASA is so exciting: The space agency, along with partners around the world, has found seven potentially Earth - like planets orbiting a star All the planets are believed to be rocky, and are all believed to be around the size of Earth , give or take 10 to 20 percent.

NASA announced the latest findings in its hunt for friendly exoplanets on Monday, and the haul includes 219 new candidates. Of those, 10 are potentially rocky and located in the habitable zones of their stars where liquid water might be found.

The findings come courtesy of NASA's pioneering Kepler space telescope, our eye in the sky when it comes to spotting potentially habitable planets beyond our solar system. It's designed to find rocky planets (not gaseous ones like Jupiter) that are located in habitable zones of stars where temperatures are temperate enough to potentially sustain life as we know it.

The Tiny Edit That Changed NASA's Future

  The Tiny Edit That Changed NASA's Future On March 21 of this year, both parties in Congress and the Trump administration made a change to a federal document that amounted to only a few words, but which may well change the course of human history. Every few years, Congress and the administration pass a NASA Authorization Act, which gives the U.S. Space Agency its marching orders for the next few years. Amongst the many pages of the 2017 NASA Authorization Act (S. 422) the Agency’s mission encompasses expected items such as continuation of the space station, building of big rockets, indemnification of launch and reentry service providers for third party claim and so on.

No Earth - like planet has been identified and verified, as of December 16, 2012 (related discussion from Rachel Courtland, New Scientist, July 28, 2010). Potentially Earth - like Planets . NASA ( Earth Observatory).

THE probability we are alone in the universe was today slashed after NASA revealed there could be as many as 10 billion Earth - like exoplanets, potentially harbouring life in our own Galaxy, The Milky Way, ALONE. Kepler telescope discovers 1,284 new planets .

Of particular note in this newest batch is KOI-7711, which could be a close cousin to Earth based on its size and distance to its sun-like star. "KOI" stands for "Kepler object of interest." "There's a lot we don't know about this planet," said Kepler researcher Susan Mullally, so it's too soon to say if KOI-7711 is truly a twin of Earth with a similar atmosphere and liquid water.

Kepler spots potential planets by looking for a dimming of a star's brightness due a planet crossing in front of it. "The latest Kepler catalog of planet candidates was created using the most sophisticated analyses yet, yielding the most complete and reliable accounting of distant worlds to date," NASA says.

So far, Kepler's missions have identified more than 4,000 candidate planets. The last big group from Kepler's K2 mission came in July 2016 with the announcement of over 100 new exoplanets. So far, NASA scientists have used Kepler to identify around 50 terrestrial-sized planets in their stars' "Goldilocks zones" where it's not too hot and not too cold.

Jupiter is the oldest planet in the Solar System

  Jupiter is the oldest planet in the Solar System Jupiter's ancient name really is well-deserved: according to a new study, the king of the planets isn't just the largest in the Solar System, it's also the oldest. The team came to the conclusion after testing for the presence and abundances of molybdenum and tungsten isotopes in some iron meteorites that fell to Earth. They found that the meteorites contained components from two distinct reservoir of materials, thanks to the data from the molybdenum isotopes. One reservoir has material from a different star than ours that didn't make it to the other reservoir.

GETTY. ALIENS? NASA reveals a new Earth - like planet called Kepler-452b. It's the most exciting discovery in over 1,000 years and has been dubbed " Earth 's Bigger, Older Cousin" by experts. US space agency NASA

Here are 10 images from NASA depicting these wild worlds. This means that Kepler-22b may have liquid water on it like Earth , making it our closest possible sister planet .

Kepler's discoveries have sparked hopes of finding Earth-like planets, but it has also dashed them. Exoplanet Kepler-438b seemed like an exciting candidate for hosting life, but in 2015 scientists announced it was actually uninhabitable due to its star's flares.

Kepler launched in 2009, but its time is limited. NASA is working on the Transiting Exoplanet Survey Satellite (TESS), which is scheduled to launch in 2018 on a fresh exoplanet-hunting mission.

Uranus' Magnetosphere Opens And Closes Each Day, Study Finds .
The planet lets in solar wind by acting like a light switch.In what could be described as its “on” position, the planet allows solar wind to flow into it. In its “off” position, the planet deflects solar wind by closing up. The process occurs each and every day, the scientists said. Earth’s magnetosphere, in contrast, typically only alters between open and closed in response to changes in solar wind.
