‘New Methodology’ in Measuring Gravity Will Aid in Finding Alien Worlds

'New Methodology' in Measuring Gravity Will Aid in Finding Alien Worlds

Advance in astronomy ‘can help find other worlds’

     The pull of gravity on a distant star can now be measured more accurately, shedding light on other worlds, say astronomers.

The method makes it possible to study even the faintest of stars.

“Our technique can tell you how big and bright is the star, and if a planet around it is the right size and temperature to have water oceans, and maybe life,” said Prof Jaymie Matthews.

Formation of Alien Worlds Photographed for 1st Time

     For the first time ever, astronomers have directly observed planets in the process of being born.

Scientists have photographed a gas-giant exoplanet forming around a young star called LkCa 15, which lies about 450 light-years from Earth.

“It’s exciting, because it’s the first time that we’ve been able to image forming planets directly,” study lead author Stephanie Sallum, a graduate student at the University of Arizona, told Space.com. “It gives us a system to follow up in the future, in depth, to really understand the details of how planets form.” […]

NASA’s Exploration of Two Potentially Life-Supporting Alien Worlds?

 Will NASA Explore Two Potentially Life-Supporting Alien Worlds?

     A decade from now, NASA probes could be on their way to explore two potentially life-supporting alien worlds.

The agency already plans to launch a spacecraft toward the Jupiter moon Europa in the early to mid-2020s, and it’s mulling a mission to the Saturn satellite Enceladus that would lift off by the end of 2021. Many astrobiologists regard Europa and Enceladus, which are both thought to harbor oceans of liquid water beneath their icy shells, as the solar system’s two best bets to host alien life.

The possible Encelacus project, known as the Enceladus Life Finder (ELF), is one of two dozen or so concepts submitted earlier this year for consideration by NASA’s Discovery Program, which launches highly focused, relatively low-cost missions to various solar system destinations. […]

5 Ancient Alien Planets Found

5 Ancient Alien Planets Found

      Five rocky alien worlds that are 80 percent as old as the universe itself have been discovered, suggesting that Earth-size planets have been a feature of the Milky Way galaxy almost since its beginning.

The new found exoplanets circle Kepler-444, an 11.2-billion-year-old star about 25 percent smaller than the sun that lies 117 light-years from Earth. All of the worlds are Venus-size or smaller and are therefore rocky, though scientists know nothing else about their composition.

All five alien planets complete an orbit in less than 10 days, meaning they’re almost certainly too hot to support life as we know it. But Kepler-444 hints at the existence of other ancient planetary systems that may be more hospitable, researchers said. . . .
