Astronomia.pl

Astronomia.pl was a Polish web portal for astronomy and space research. It was founded in 2001 [1] and was active until 2015. [2] While active, it was the largest astronomy and space portal in Poland, hosting over 3000 articles at its prime. [1]

CalSky

CalSky (sky calendar) was web based astronomical calculator used by astronomers to plan observing. It was created by Arnold Barmettler a researcher at the University of Zurich and formerly a scientific assistant at the European Space Agency. [3] The website, available in English and German, featured a calendar (and/or email notifications) generated for your location including information on aurora, comets, tides, solar and lunar eclipses, planets, bright satellite passes (ISS, HST, etc.), occultations, transits, iridium flares, and decaying satellites that may be visible. [4] [5] [6] In 2020, the website ceased operation.

Exoplanet Archive

The NASA Exoplanet Archive is an online astronomical exoplanet catalog and data service that collects and serves public data that support the search for and characterization of extra-solar planets (exoplanets) and their host stars. It is part of the Infrared Processing and Analysis Center (IPAC) and is on the campus of the California Institute of Technology (Caltech) in Pasadena, CA. The archive is funded by NASA and was launched in early December 2011 by the NASA Exoplanet Science Institute (NExScI) as part of NASA's Exoplanet Exploration Program.

Exoplanet Data Explorer

The Exoplanet Data Explorer lists extrasolar planets up to 24 Jupiter masses. [7] [8]

Extrasolar Planets Encyclopaedia

The Extrasolar Planets Encyclopaedia [9] is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, [10] [11] which maintains a database of all the currently known and candidate extrasolar planets, with individual "note" pages for each planet and a full list interactive catalog spreadsheet. The main catalogue comprises databases of all of the currently confirmed extrasolar planets as well as a database of unconfirmed planet detections. The databases are frequently updated with new data from peer-reviewed publications and conferences.

Galaxy Zoo

Galaxy Zoo is an online astronomy project which invites members of the public to assist in the morphological classification of large numbers of galaxies. It is an example of citizen science as it enlists the help of members of the public to help in scientific research. An improved version—Galaxy Zoo 2—went live on 17 February 2009. The current iteration of the project, launched in April 2010, is Galaxy Zoo: Hubble, and uses Hubble Space Telescope survey data. It is part of the Universe group of citizen science projects.

Space.com

Space.com is a space and astronomy news website. Its stories are often syndicated to other media outlets, including CNN, MSNBC, Yahoo!, and USA Today. Space.com was founded by former CNN anchor Lou Dobbs and Rich Zahradnik, in July 1999. At that time, Dobbs owned a sizeable share of the company, and, in an unexpected move, left CNN later that year to become Space.com's chief executive officer. [12]

Universe Today (UT) is a non-commercial space and astronomy news site, founded in 1999 [13] by Fraser Cain and edited by Nancy Atkinson. [14] [15] The news can then be discussed on the forums. The forum began on 24 July 2003, and was mainly used to discuss the Universe Today news as well as ask space-related questions and discuss alternate theories. [15] In early September 2005, the forum merged with that of Bad Astronomy combined to form the BAUT forum. [16] The website's viewership attains several million people per year. [17] [18]

Emily Lakdawalla, of The Planetary Society, said that she relies on Universe Today and Bad Astronomy to "give ... an independent look at big news stories" [19] and that UT plays a key role in space-related journalism, along with other websites such as Space.com . Several peer-reviewed papers have mentioned Universe Today as being a space-related news website. [20] [21] [22]

In 2008 the site was briefly banned for about a day from Digg.com, and then unbanned. [18] [23] In March 2011, Businessweek reported that the site had lost 20 percent of its traffic in five days after a change in the page ranking algorithm of Google. [24] In April 2011, the Association of British Science Writers noted that Universe Today decided to ignore embargoed stories. [25]

TW Hydrae is a T Tauri star approximately 196 light-years away in the constellation of Hydra. TW Hydrae is about 80% of the mass of the Sun, but is only about 5-10 million years old. The star appears to be accreting from a protoplanetary disk of dust and gas, oriented face-on to Earth, which has been resolved in images from the ALMA observatory. TW Hydrae is accompanied by about twenty other low-mass stars with similar ages and spatial motions, comprising the "TW Hydrae association" or TWA, one of the closest regions of recent "fossil" star-formation to the Sun.

Universe Today (U.T.) is a North American-based non-commercial space and astronomy news website founded by Fraser Cain. The domain was registered on December 30, 1998, and the website went live in March 1999. Universe Today assumed its current form on July 24, 2003, featuring astronomy news and other space-related content.

<span class="mw-page-title-main">Kepler-6</span> G-type star in the constellation Cygnus

Kepler-6 is a G-type star situated in the constellation Cygnus. The star lies within the field of view of the Kepler Mission, which discovered it as part of a NASA-led mission to discover Earth-like planets. The star, which is slightly larger, more metal-rich, slightly cooler, and more massive than the Sun, is orbited by at least one extrasolar planet, a Jupiter-sized planet named Kepler-6b that orbits closely to its star.

Kepler-8 is a star located in the constellation Lyra in the field of view of the Kepler Mission, a NASA-led operation tasked with discovering terrestrial planets. The star, which is slightly hotter, larger, and more massive than the Sun, has one gas giant in its orbit, Kepler-8b. This gas giant is larger than Jupiter, but is less massive, and thus more diffuse. The planet's discovery was announced to the public on January 4, 2010 along with four other planets. As the fifth confirmed planetary system verified by Kepler, it helped demonstrate the capabilities of the Kepler spacecraft.

Kepler-1520 is a K-type main-sequence star located in the constellation Cygnus. The star is particularly important, as measurements taken by the Kepler spacecraft indicate that the variations in the star's light curve cover a range from about 0.2% to 1.3% of the star's light being blocked. This indicates that there may be a rapidly disintegrating planet, a prediction not yet conclusively confirmed, in orbit around the star, losing mass at a rate of 1 Earth mass every billion years. The planet itself is about 0.1 Earth masses, or just twice the mass of Mercury, and is expected to disintegrate in about 100-200 million years. The planet orbits its star in just 15.7 hours, at a distance only two stellar diameters away from the star's surface, and has an estimated effective temperature of about 2255 K. The orbital period of the planet is one of the shortest ever detected in the history of the extrasolar planet search. In 2016, the planet was confirmed as part of a data release by the Kepler spacecraft.

<span class="mw-page-title-main">Kepler-62</span> K-type star in the constellation Lyra

Kepler-62 is a K-type main sequence star cooler and smaller than the Sun, located roughly 980 light-years from Earth in the constellation Lyra. It resides within the field of vision of the Kepler spacecraft, the satellite that NASA's Kepler Mission used to detect planets that may be transiting their stars. On April 18, 2013, it was announced that the star has five planets, two of which, Kepler-62e and Kepler-62f are within the star's habitable zone. The outermost, Kepler-62f, is likely a rocky planet.

<span class="mw-page-title-main">Kepler-62e</span> Habitable-zone super-Earth planet orbiting Kepler-62

Kepler-62e is a super-Earth exoplanet discovered orbiting within the habitable zone of Kepler-62, the second outermost of five such planets discovered by NASA's Kepler spacecraft. Kepler-62e is located about 990 light-years from Earth in the constellation of Lyra. The exoplanet was found using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Kepler-62e may be a terrestrial or ocean-covered planet; it lies in the inner part of its host star's habitable zone.
