Scientists have developed a new way of measuring the magnetic field of exoplanets, allowing astronomers to understand more about these far-away planets and possibly identify those outside our solar system that are habitable, according to new research.
In recent decades, scientists have been more proactive in their search for alien life, and thanks to a host of discoveries, that possibility now seems more plausible than ever. But what happens once we find life beyond Earth?
Uranus has always been a pretty lonely planet. The seventh planet from the Sun, this "ice giant" made primarily of ice particles, hydrogen, and helium is relatively unique, drifting around our solar system in an unusual elliptical orbit at a stunning 99 degrees axial tilt. Now, however, researchers are saying that the baby-blue planet has an unlikely twin 25,000 light-years away.
Most experts are too worried about the state of Earth's climate to be looking to the stars, but now a team of astronomers have used NASA's Hubble Telescope to help reveal what kind of temperatures and precipitation are felt on an exoplanet 260 light-years away.
It's clear skies on the planet HAT-P-11b, making it easy for astronomers to spot steamy water vapor on this Neptune-sized exoplanet, new research describes.
Experts have recently decided to revisit the question "what is a planet?" citing the fact that it remains unclear if many of the hundreds of exo-planets observed in far-off solar systems are actually true planets, or just various "planetoids" or dwarf planets like Pluto was first demoted to back in 2006.
Like a pesky child can appear to rapidly age their tiring parent, a star about 330 light years away is looking a lot worse for wear, thanks to the giant exoplanet that constantly encircles it.
Companionship is apparently something that planets, like people, value in old age. It turns out that a companion planet might be useful in giving an old, less habitable world a new chance at life.
NASA knows exactly how large a new "super Earth" exoplanet is, thanks to a combined effort from the Kepler and Spitzer Space Telescopes. This, according to NASA, is the most accurate measurement of this kind of exoplanet ever taken, and marks a new step towards better understanding these planetary bodies.
Experts have been using NASA's Hubble Space Telescope to take closer looks at potentially Earth-like exoplanets. But in searching for traces of water vapor, they've come up dry.
Astronomers have recently discovered a transient exoplanet with the longest year ever seen. Circling its star once every 704 days, Kepler-421b easily wins the title of longest orbit among known exoplanets.
NASA says that finding life beyond Earth is within our reach, even if we cannot physically reach these exoplanets. Still, some experts might disagree that habitable planets are as common as NASA thinks.
Two "goldilocks" planets recently identified by astronomers have been proven to not be as "just right" for life as was initially through. In-fact, they may not even exist at all according to a recent study.
Astronomers now have an innovative new tool that is able to detect methane on alien planets. The organic molecule, widely acknowledged to be a sign of potential life, could be the key to finding organisms beyond Earth.
The number of planets that could support life in this universe may be far smaller than what experts once thought. According to a new study, planets that orbit red-dwarf stars face extreme space weather, making it less likely that life could survive .
