7:48 PM | Simulate the transit of extrasolar planets
by @ulaulaman about #exoplanets #planetary_transit #kepler_mission #nasa #astronomy The search for extrasolar planets (or exoplanets) had its first success in 1991 with the discovery of some planets orbiting around the pulsar PSR1257+12(1, 2, 3), measuring the variations of the radio pulses coming from the star. The second important milestone in exoplanet research takes place in 1995, with the discovery around the star 51 Pegasi (a star like our Sun) of a Jupiter-like planet, found at a […]

2:03 PM | Kepler-186f: Potentially Habitable Earth-like Exoplanet Found
A large team of astronomers has announced the discovery of an Earth-sized exoplanet orbiting within the habitable zone of Kepler-186. Kepler-186 is a M1-type dwarf star located in the constellation Cygnus, about 500 light years away from Earth. The star hosts at least five planets, four of which – Kepler-186b, Kepler-186c, Kepler-186d, and Kepler-186e – [...]

12:20 PM | Kepler Finds First Earth-size Planet in the Habitable Zone
In a April 17 news release NASA has announced that astronomers using the Kepler Space Telescope have discovered the first Earth-size planet orbiting a star in the circumstellar habitable zone, or the range of distance from a star where liquid water might pool on the surface of an orbiting planet, aka the Goldilocks Zone. Though […]

In sci-fi films we often see people being sucked out of their spaceship by holes blown in walls, but what really happens to us in space when we leave behind the essentials? As a carbon-based life form adapted to Earth’s conditions, we’re not suited to fleeing off into space armed only with the ability to …

4:49 AM | First "Earth Cousin" Planet Found
Astronomers working with the Kepler telescope, led by Elisa Quintara of the SETI Institute, have announced the discovery of the first planet orbiting another star that meets the two characteristics we have been particularly waiting for.  The planet is Earth-sized AND it orbits its star in the zone where water is likely to be liquid (called the “habitable zone.”)The planet and star have no name, but only a catalog number – Kepler 186.  Located in the constellation of […]

10:43 PM | Discovery of Earth-Sized Planet in Habitable Zone of a Star
Since its inception in Spring 2009, NASA’s Kepler Space Telescope has been hunting exoplanets, or planets outside the Solar System, the holy grail being a planet similar to ours in terms of size, composition, and habitability. In its mission, Kepler utilizes the transit method: it continuously measures the brightness of 150,000 stars, looking for dips in […]
