"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 5,000 exoplanet...
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
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 you counted all the stars in the Milky Way at the rate of one per second, it would take you about 3200 years to finish counting our one galaxy’s set of stars. How many stars inmy skynow? Ok. So, let’s get real. Now we know how many stars there may be in the entire kno...
Astronomers have observed a solar system where six planets are in perfect sync with each other as they dance through space around their star, a rare find in the galaxy. About 100 light-years away in the northern constellation of Coma Berenices, these exoplanets, studied with NASA and other ...
Although many of these things they have about 80-90% of the info about, we simply do not yet have the technology to absolutely prove them to be facts...so they are giving us the best information they have to date, and using phrases like "We THINK" Etc, BECAUSE ppl like the ones wh...
Before we had discovered exoplanets, astronomers generally thought our solar system was rather typical. Sure, there would be differences, but the general arrangement of rocky worlds close to the Sun and cold gas giants in the outer system made sense. However when we studied planetary systems we ...
Exoplanets. Let’s toss around some more big numbers. First, how many are there? Based on observations made byNASA’s Kepler space telescope, we can confidently predict that every star you see in the sky probably hosts at least one planet. Realistically, we’re most likely talking about mul...
Auroras are expected to be relatively common in the skies of exoplanets as well. But we'll have to get better looks at these faraway worlds to see their light shows directly. The history of the northern lights Though it was Italian astronomer Galileo Galilei who coined the name "aurora borea...
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...
