HOW MANY KNOWN EXOPLANETS SMALLER THAN EARTH EXIST?The article offers information on the existence of exoplanets in the solar system which include Kepler-20f, Kepler-68c, and Kepler-20e.Astronomy
The PLATO and Roman telescopes will be invaluable for discovering new exoplanets and estimating how many exoplanets exist in total in our galaxy. But once we know how many planets there are and where they are located, we need new tools to learn more about these planets — investigating characte...
Ultimately, the aim is to dispatch a spacecraft to one of the nearest exoplanets. One project, calledBreakthrough Starshot, is developing tiny, sensor laden probes weighing just 1 gram that it hopes to shoot through space on light sails to beam back data onProxima b, a world 4.2 light yea...
If Other Kinds of Nervous Systems Exist in the Universe, How Do We Locate and Identify Them? (exoplanets or their moons) for alien life everywhere in space, many of our space and life scientists are now beginning to feel the urgent need to begin making preparations for investigating what may...
There are a handful of other known exoplanets with three host stars, and quite a few out there with two suns. (This latter group is sometimes nicknamed "Tatooine" planets, after Luke Skywalker's home world in the "Star Wars" films.) Where does all this multistar madness end? Is it pos...
One of the most surprising discoveries in the past couple decades is the existence of so-called "hot Jupiters," which are giant exoplanets that orbit way too close for comfort to their parent stars. In short, they shouldn't exist. Gas giant planets need a lot of gas to become giant (he...
Sadly both of these exoplanets are too far away for the James Webb telescope to investigate. While we didn't find any exoplanets nearby in both the habitable and abiogenesis zones, we are discovering such worlds at breathtaking speed – with several thousands discovered already. So it may not ...
Exoplanets near the galactic center could accumulate sufficient dark matter to keep them warm enough to sustain life. Image credit: ESO Dark matter, inferred to exist from its gravitational effects on the universe, is still a mystery to scientists. But a new study says that dark matter could ...

HOW MANY ALIEN PLANETS ARE OUT THERE? "The interesting thing about these planets is that they are mostly in this little bubble around our solar system, where they are easier to find," Christiansen explained in theCaltech news release. "Of the 5,...
