    The number of known exoplanets made a big jump up in November 2021, when astronomers announced a whopping 301 newly confirmed planets and an additional 366 new planet candidates. NASA’s Kepler planet-hunter – a space observatory – gathered the data. Kepler launched and began operations in 2009. It ran out of fuel and was retired in late 2018. But astronomers are still mining the mission’s data, making new discoveries of distant worlds... Overall, the Kepler mission was immensely successful. As of December 6, 2021, astronomers recognize 4,888 confirmed exoplanets. It’s not an exaggeration to say that Kepler single-handedly discovered most...

NASA/MIT/TESS ==================================================================== The researchers at NASA’s Frontier Development Lab (FDL) in Mountain View California just spent the summer working on out-of-this-world problems. They came from all over the globe and all different disciplines; computer science engineers, planetary scientists, even a particle physicist. For eight weeks they dug through data and maps, created worlds and atmospheres, sorted them, and tested their computer algorithms against the simulations. Their final products are still rough,...

    Credit: Instituto de Astrofísica de Canarias __________________________________________________________________________ The Instituto de Astrofísica de Canarias (IAC) and the University of Oviedo present today the discovery of two new planetary systems, one of them hosting three planets the same size as the Earth. The information about these new exoplanets has been obtained from the data collected by the K2 mission of NASA's Kepler satellite, which started in November 2013. The work, which will be published in the Monthly Notices of the Royal Astronomical Society (MNRAS), reveals the existence of two new planetary systems detected from the eclipses they produce in the stellar...

    For centuries, human beings have wondered about the possibility of other Earths orbiting distant stars. Perhaps some of these alien worlds would harbor strange forms of life or have unique and telling histories or futures. But it was only in 1995 that astronomers spotted the first planets orbiting sunlike stars outside of our solar system. In the last decade, in particular, the number of planets known to orbit distant stars grew from under 100 to well over 2,000, with another 2,000 likely planets awaiting confirmation. Most of these new discoveries are due to a single endeavor—NASA's Kepler mission. Kepler is...

    This artist's concept depicts a planetary system. Credit: NASA/JPL-Caltech An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar sizes and a regular orbital spacing. This pattern, revealed by new W. M. Keck Observatory observations of planetary systems discovered by the Kepler Telescope, could suggest that most planetary systems have a different formation history than the solar system. Thanks in large part to the NASA Kepler Telescope, launched in 2009, many thousands of exoplanets are now known. This large sample allows researchers to not only...

    Planet-hunters are always on the lookout for worlds that look like Earth—rocky planets that are not too hot and not too cold for liquid water to flow on the surface. Now scientists have hit the jackpot, discovering seven Earth-size exoplanets orbiting a single star just 39 light-years away. The star, named TRAPPIST-1, was thought to be home to three exoplanets. But with the help of a variety of observatories—including the Transiting Planets and Planetesimals Small Telescope (a.k.a. TRAPPIST, the star's namesake), the Very Large Telescope in Chile, and NASA's Spitzer Space Telescope—researchers found four more planets in the system. The...

    2K 6 Forbidden planets: Understanding alien worlds once thought impossible By Daniel CleryJul. 28, 2016 , 2:00 PM When astronomers discovered the first exoplanet around a normal star 2 decades ago, there was joy—and bewilderment. The planet, 51 Pegasi b, was half as massive as Jupiter, but its 4-day orbit was impossibly close to the star, far smaller than the 88-day orbit of Mercury. Theorists who study planet formation could see no way for a planet that big to grow in such tight confines around a newborn star. It could have been a freak, but soon, more “hot Jupiters” turned...

    An international team of scientists said Monday they had discovered a trio of Earth-like planets that are the best bet so far for finding life outside our solar system. The three orbit an ultracool dwarf star a mere 39 light years away, and are likely comparable in size and temperature to Earth and Venus, they reported in a study, published in Nature.

    For a planet to have liquid water -- something necessary to support life as we know it -- it has to be within a certain distance of its star. Too close, and the water burns up. Too far away, and it's a frozen wasteland. But according to new research, most stars in the galaxy have so-called "Goldilocks planets," which sit in the habitable zone, where temperatures are just right for life... The calculations, which were produced by a group of researchers from the Australian National University and the Niels Bohr Institute at the University of Copenhagen, are based on a...

    The more planetary systems astronomers discovered, the more our own solar system looked like an oddball. Exoplanets – at least the ones big enough for us to see – tended to be bigger than Earth, with tight orbits that took them much closer to their host stars. In multi-planet systems, these orbits tended to be much closer together than they are in our solar system. For instance, the star known as Kepler-11 has six planets closer to it than Venus is to the sun. Why does our solar system look so different? Astrophysicists Konstantin Batygin of Caltech and Greg Laughlin...

    Life on Earth exists becuase of the sun and our distance from it. Without that star and the energy it gives off, we’d be what NASA once described as a “lifeless ball of ice-coated rock.” Luckily, we are far enough from it, and as of right now, it’s not radiating so much light as to make our planet uninhabitable. In some ways, we’re in the sweet spot, and researchers may have discovered many more such connections. Stars in the Milky Way may have 100 billion planets — two, on average, per star — in their habitable zone, the area far...

    A rare event in the heavens just ahead of Christmas will feature an alignment of planets that a famous astronomer believed was the phenomenon that is mentioned in the Bible when Jesus Christ was born. The alignment of Jupiter and Saturn will appear in the skies on December 21, the winter solstice. The last time the rare alignment of the planets was this close was in 1623, nearly 400 years ago. That was only 14 years after Galileo discovered the moons of Jupiter with the invention of the telescope. Another famous astronomer, Johannes Kepler, posited in 1614 that the alignment...

    Scientists analyzing data gathered by Kepler, which NASA retired in November 2018, just found a hidden gem: an Earth-size world that may be capable of supporting life as we know it. The exoplanet, Kepler-1649c, circles a red dwarf star that lies 300 light-years from Earth, a new study reports. Kepler-1649c completes one orbit every 19.5 Earth days, putting the alien planet in its host star's "habitable zone," the just-right range of distances where liquid water could exist on a world's surface. (Because red dwarfs are so dim, their habitable zones lie quite close.) "This intriguing, distant world gives us even...

    Faith of Famous Astronomers, one being a church organist who discovered a planet - Sir William Herschel Polish astronomer Nicolaus Copernicus (1473-1543), made a major contribution to the scientific revolution by discovering that the planets did not revolve around the Earth (geocentric), but instead the Earth, as well as all the other planets in the solar system, revolved around the Sun (heliocentric). Copernicus, who had a doctorate in cannon church law, wrote: "The Universe, wrought for us by a supremely good and orderly Creator." Copernicus wrote: "To know the mighty works of God, to comprehend His wisdom and majesty and...

    In a clean room inside a clean room at NASA’s Kennedy Space Center, a petite telescope is perched on a stand for a final series of checkouts prior to launch. The extra fastidiousness is because the observatory’s four cameras will fly without protective covers—one of several simplifying design decisions made to help ensure the Transiting Exoplanet Survey Satellite, or TESS, will meet its goal of measuring the masses of at least 50 small, rocky and potentially Earth-like worlds as part of the first all-sky, exoplanet survey. TESS was proposed even before NASA’s planet-hunting Kepler space telescope, launched in 2009, demonstrated...
