Kepler Mission
-
Based on data from the Kepler Space Telescope and the Gaia mission, there may be up to 300 million habitable planets in our galaxy. The research refines a key factor in the Drake equation that estimates how many extraterrestrial civilizations may exist.
-
A team of scientists has identified two dozen exoplanets that could be more favorable to life than the Earth. These super-habitable worlds may have conditions more suitable to sustaining life for a longer period of time than our planet.
-
For the first time, astronomers have used a machine learning algorithm – a form of self-teaching AI – to confirm the existence of 50 new exoplanets in data collected by the now retired Kepler space telescope.
-
To get a sense of how “normal” the Sun may be, astronomers have compared the Sun to hundreds of similar stars. It turns out that it’s actually far less active than its peers – but is this a permanent personality, or is it just going through a phase?
-
A review of early data returned by NASA's Kepler mission has revealed one of the most Earth-like exoplanet discovered so far. The new planet is slightly larger than ours, is estimated to have a similar temperature, and orbits in the habitable zone.
-
Water is crucial to life as we know it, so it’s one of the key things astronomers look out for on exoplanets. And now, water vapor has been detected in the atmosphere of a potentially habitable exoplanet for the first time.
-
Just how common are potentially habitable Earth-like planets? Researchers on a new study claim to have come up with the most accurate estimate yet – and they’re more common than you might think.
-
Astronomers have discovered a weird star system that appears to be dimming completely at random, and none of the usual explanations seem to fit.
-
Another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Earth-sized – much smaller than the Neptune-sized average found so far. The discovery was made in old data, using a new and more sensitive algorithm.
-
After nine years, NASA's exoplanet-hunting Kepler mission came to a final end Thursday as the space agency sent the radio commands ordering the onboard computer to shut down the unmanned space telescope's systems.
-
The pioneering planet-hunting Kepler Space Telescope has finally reached the end of its service life and will be switched off permanently. NASA announced today that the aging, unmanned spacecraft has run out of the propellant needed to keep it from tumbling and must be retired.
-
Although it’s basically a sure thing that exomoons are out there, astronomers haven’t been able to spot any – until now. Scientists using NASA’s Hubble and Kepler space telescopes have found evidence of a large moon orbiting a gas giant planet some 8,000 light-years away.
