As the number of exoplanets discovered continues to grow exponentially, the number of potentially habitable worlds out there continues to increase as well. Astronomers have now reported finding another one of the nearest known of these kinds of planets so far, Gliese [...]

Today was another big day for those interested in space exploration and in the search for other Earth-like, alien worlds in particular: The first Earth-sized exoplanet orbiting another star in the habitable zone has been discovered, it was [...]

Exoplanet Bonanza: Kepler Confirms More than 700 New Worlds

There was more exciting exoplanet news this week from the Kepler mission: the space telescope has confirmed 715 new exoplanets! This brings the current total number of such worlds to 1,766, of which 961 have been found by Kepler. There are [...]

European Space Agency Selects PLATO Observatory for Proposed 2024 Launch

From the European Space Agency (ESA): “The PLAnetary Transits and Oscillations of stars (PLATO) mission will identify and study thousands of exoplanetary systems, with an emphasis on discovering and characterising Earth-sized planets and super-Earths. It will also investigate seismic activity in stars, enabling a precise characterisation of the host sun of each planet discovered, [...]

Kepler Finds a Very Wobbly Planet

This illustration shows the unusual orbit of planet Kepler-413b around a close pair of orange and red dwarf stars. The planet’s 66-day orbit is tilted 2.5 degrees with respect to the plane of the binary star’s orbit. The orbit of the planet wobbles around the central stars over 11 years, an effect called precession. [...]

Planets, Planets Everywhere

What a wonderful and amazing Scheme have we here of the magnificent Vastness of the Universe! So many Suns, so many Earths, and every one of them stock’d with so many Herbs, Trees and Animals, and adorn’d with so many Seas and Mountains! And how must our wonder and admiration be encreased [...]

Carbon Worlds May Be Waterless, Finds NASA Study

This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in carbon — and dry. Chances are low that life as we know it, which requires liquid [...]

The Space Race, one of many fronts of the Cold War, began in earnest on July 29, 1955, when President Eisenhower publicly announced Project Vanguard, the first genuine effort to launch a man-made vehicle into orbit as an instrumented scientific experiment for the International Geophysical Year. Bypassing Werner Von Braun’s more [...]

Kepler Recovery Efforts Conclude, Other Missions Mulled

After several months’ worth of review and testing, the team operating the Kepler Space Telescope has opted to close its efforts to make Kepler fully operational again. This follows the loss of one of the crucial components that controls the alien planet-hunting spacecraft. In an Aug. 15 teleconference, Charles Sobeck, deputy [...]
