This year brought us one of the most exciting discoveries yet: a system of seven worlds that sets a new record for the greatest number of habitable-zone planets found around a single star. All seven of TRAPPIST-1 planets could have liquid water under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
The three planets in the habitable zone are in the area around the parent star where a rocky planet is most likely to have the temperature for liquid water— which is key to life as we know it. But recent findings suggest life would have an uphill battle on a planet close to a red dwarf star like TRAPPIST-1, largely because such stars are extremely active in their early years—shooting off potentially lethal flares and bursts of radiation.
Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler, a Sun-like star 2, light-years from Earth. The newly-discovered Kepleri — a sizzling hot, rocky planet that orbits its star once every In this case, computers learned to identify the signals caused by planets by finding instances in Kepler data where the telescope recorded changes in starlight caused by planets beyond our solar system, known as exoplanets.

This week's planetary profusion consists of 11 transiting planets—including a new Kepler planet— and six found with radial velocity. These bring the total confirmed planet count to 4, If you use the astroquery.
No changes in syntax are required, but note that methods that previously queried the Confirmed Planets table exoplanets , which returned one row per planet, now query the PS table, which can return multiple rows per planet.
Support for querying the retired tables exoplanets , exomultpars , and compositepars has now been discontinued. AstroQueryPy's module documentation and examples have been updated to reflect these changes. Let us know if you find any issues! Read the discovery paper and NASA's media release , which includes a two-minute video illustrating these two interesting systems, and then check out the two systems' overview pages. Here are some resources:.
This week's 10 new planets have something in common: they all orbit cool stars—as in, M dwarfs and K dwarfs. This week's data include two new planets, Kepler d and GJ c , and radial velocity planet parameters for known exoplanets.
We've added 21 planets this week, two of which were discovered by citizen scientists participating in the Zooniverse Planet Hunters TESS project. You can also see all the new data in the Planetary Systems Table and its companion table, Planetary Systems Composite Parameters , which offers a more complete table of planet parameters combined from multiple references and calculations.
This latest contributed data set by Werner et al. The data file can be downloaded from the SpiKeS documentation page. This week's crop of exoplanets includes TOI b, a Neptune-sized gas world that orbits a very bright red-dwarf star—a rare occurrence that may provide opportunities for atmospheric data observations for exoplanet characterization. The archive has added a new synthetic spectra data set and machine learning model to help users model atmospheric observations and retrieve atmospheric properties.
The Machine learning Algorithm for Radiative transfer of Generated Exoplanets MARGE is a Python package that trains a user-specified neural network architecture to approximate a deterministic process, based on some data generated by a forward model.
The archive hosts the reproducible research compendium RRC of Himes et al. Read the documentation for further details and to access the data. The central "star" is only 15 MJup and twice the mass of the planetary companion. Check out the host's cool as in low temperature graphic on its System Overview page! We've also added new data for 11 previously published planets. See the new data in the Planetary Systems Table and its companion table, Planetary Systems Composite Parameters , which offers a more complete table of planet parameters combined from multiple references and calculations.
As a reminder, the Confirmed Planets, Extended Planet Data, and Composite Parameters tables have been retired and are no longer updated. Please use the Planetary Systems tables for the most current published system data. To recap the recent the changes to the archive's tools and services, please see Developing a More Integrated Exoplanet Archive and the Archive 2. Please note the database colum names have also changed. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier.
If you were to come up with a punchline to a joke about the Monitor, that would probably be it. But you know what? We change lives. We have a mission beyond circulation, we want to bridge divides.
