Planets that begin with the name Kepler were discovered by theKepler space telescopethat was launched in 2009 to study a small region of space inCygnuswhere there is a large number of stars. Its original mission timeline was supposed to be three and a half years, but it is still going str...
The water in the magma can combine with these iron droplets as they sink toward the core. "The iron droplets behave like a raft that is conveyed downwards by the water." This is fine for planets of Earth's stature, but many of the rocky exoplanets being discovered by astronomers are ...
51 Pegasi bwas the first exoplanet discovered orbiting a sunlike star. It was found in 1995 by astronomers Michel Mayor and Didier Queloz, with the duo sharing the2019 Nobel Prize in physicsfor the breakthrough (along with James Peebles "for theoretical discoveries in physical cosmology.") Foun...
With CoRoT (2007-2012), the pioneering CNES space-based mission in this investigation, about thirty new planets were characterized. CoRoT has enhanced the diversity of giant exoplanets and discovered the first telluric exoplanet. Following CoRoT, the NASA Kepler mission has extended our knowledge ...
Johannes Kepler discovered the Three Planetary Laws that define orbital motion, so it is only fitting that the telescope used to find exoplanets bears his namesake. Thousands of planet candidates have been found and more await us. It is simply amazing how much we have found in such a short ...
In the Solar System, the Jacobi triaxial ellipsoid has successfully described the shape of Haumea and Chariklo, while Ceres appears to be an oblate spheroid of the Maclaurin type. Beyond the Solar System, new exoplanets are being discovered almost daily showing vastly different characteristics (e.g...
Exoplanet surveys around M dwarfs have detected a growing number of exoplanets with Earth-like insolation. It is expected that some of those planets are rocky planets with the potential for temperate climates favourable to surface liquid water. However,
Three decades after Cornell astronomer Carl Sagan suggested that Voyager 1 snap Earth's picture from billions of miles away—resulting in the iconic Pale Blue Dot photograph—two astronomers now offer another unique cosmic perspective:
The research was published on December 28, 2023, inNature Astronomy. The Science Behind the Discovery Habitability is a theoretical astronomical concept that means that a celestial body is capable of hosting and retaining liquid water on its surface. Planets too close to their star are too hot...
In contrast, space and ground telescopes have observed that hydrodynamic escape still occurs on some exoplanets that are very close to their host stars. This process not only changes the planet’s mass but also affects the planet’s climate and habitability. ...
