MORE Updated KOI Dispositions! The Kepler project has delivered false positive flags and updated dispositions for 44 KOIs in the Q1-Q12 activity table, bringing the total number of Kepler candidates and confirmed planets to 4,178 in Cumulative table. For more information, see the Purpose of KOI activity table, the KOI Cumulative and Q1-Q12 interactive tables and the KOI column definitions.

Always Show Scroll Bars in Mac OS X: Starting with OS X Lion, Apple changed how scroll bars appear (and disappear) by default, making them fade away when not in active use.  This can make it difficult or impossible to scroll in some interfaces, including our interactive tables. Fortunately, there is a simple solution. See our FAQ for details.

October 23, 2014: The Kepler project has updated dispositions for 133 KOIs in the Q1-Q16 activity table, bringing the total number of Kepler candidates and confirmed planets to 4,183 in the Cumulative table. This delivery is also the first to include flags that denote reasons why a KOI was given a FALSE POSITIVE disposition. The four flags populated with this delivery are: Centroid Offset, Significant Secondary, Ephemeris Match Indicates Contamination and Not Transit Like. For more information, see the Purpose of KOI Activity Table, the KOI Cumulative and Q1-Q16 interactive tables, and the KOI column definitions.

    February 26, 2014: We've added 715 new Kepler planets from the Rowe et al. 2014 paper, as described in today's press release. With today's announcement, Kepler now accounts for 57% of all confirmed planets. Please note the default names of planets from Xie 2013 and Xie 2014 have been updated to reflect their Kepler Names to be more consistent with the published versions and the Rowe et al. paper. We've also removed 60 planets from the archive for various reasons, which are described on the Removed Targets page.

    February 19, 2014: We've just added additional CoRoT light curve data sets for run codes LRa05, LRa06, LRc07, LRc08, LRc09, SRa04, SRa05, and SRc03 for both the Astero-Seismology and Exoplanet Survey channels. This release includes 25 new Astero-Seismology light curves and 32,007 new Exoplanet Survey light curves. To access, click the CoRoT Astero-Seismology and Exoplanet links on the left side of our home page, or from the Data drop-down menu at the top of the page.

    February 13, 2014: The Kepler project has updated dispositions for 534 KOIs in the Q1-Q16 KOI activity table. This brings the total number of Kepler candidates and confirmed planets to 3,841. For more information, see the Purpose of KOI Table document and the interactive tables.

    February 6, 2014: One planet added this week: HAT-P-49 b.

    Did you know we have video demos? There are currently demos on using the Viewable Transit Service and the Community Follow-up Observing Program (CFOP), and we are in the process of creating more videos. Access the videos from the Videos page.

    January 30, 2014: Eight new planets added: HD 154857 c, HD 114613 b, Kepler-138 c, Kepler-138 d, Kepler-412 b, Kepler-413 b, UZ For b and UZ For c.

    January 28, 2014: Kepler light curve data sets for Quarter 17 are now available in the archive. To access, click the Kepler Light Curves link on the left side of our home page, or from the Data drop-down menu at the top of the page. Additionally, all Q13 light curves are now public and also available in the archive.

    Also, did you know you have access to more than 21 million light curves in the Exoplanet Archive? In addition to Kepler data, we have light curves from SuperWASP, the CoRoT Exoplanet Survey and CoRoT Asteroseismology, HATNet, XO, TrES and KELT. A complete listing of the archive's data can be found on the Holdings page.

    January 15, 2014: Seven more planets added: MOA-2011-BLG-322L b, CoRoT-27 b, Kepler-105 b, Kepler-130 c, Kepler-411 b, WASP-103 b, and Kepler-51 d. Also, the Kepler project has added 412 new KOIs to the Q1-16 and Cumulative tables. For more details, see the documentation.

    January 14, 2014: In case you missed it, we started off the new year with surpassing 1,000 planets in the archive! See the full story on the Planetquest site.

    January 7, 2014: This week we've added 39 new Kepler planets—all from the Marcy et al. (2014) paper. This brings our planet count in the archive to 1,015! Note that KOI decimal numbers of 10 and above (e.g. KOI 244.10) are not assigned by the Kepler project and are often used by authors to denote non-transiting planets in Kepler systems with known transiting planets or candidates. For more information, see our FAQ.

    Also, the Kepler project has closed the KOI activity table for Q1-Q8. Therefore, no further changes will be made to that data set. For more information, see the associated paper (Burke et al 2013).
