Small Planets Discovered at a Faster Pace ; Anybody out There? Astronomers Announce Recent Discoveries of Two Earth-Like Planets
Astronomers have discovered three Earth - sized planets orbiting a small red sun, 40 light - years away, according to research published in the journal Nature on May 2.Researchers say all three worlds are potentially habitable and could represent the best targets yet in the search for life ...
Using the 10-meter telescope at theKeck Observatoryin Hawaii, an international team of astronomers discovered anEarth-like planet orbiting a white dwarf star4,000 light-years from Earth. This planet orbits its star, about half the mass of our Sun, at a distance roughly twice th...
This mission will scan the heavens for Earth-like planets orbiting Sun-like stars with instruments designed to cope with the star-noise that Kepler unexpectedly discovered. The team involves some 300 scientists and engineers from over 40 institutions, most in China. And this week, the ...
On one side, we can create an oxygenated world in our model without needing a succession of specific tectonic or biological events to do so, meaning that one might expect more photosynthetic Earth-like planets, with an atmosphere, ocean and active crustal recycling, to be oxygen-rich. However...
A temperate planet has been discovered orbiting Proxima Centauri, the closest M dwarf5, but it probably does not transit and its true mass is unknown. Seven Earth-sized planets transit the very low-mass star TRAPPIST-1, which is 12 parsecs away6,7, but their masses and, particularly, ...
From a distance, the sun and all its planets may look like perfect spheres. They're not. Centrifugal force and "self-gravity" combine to keep them in the shape of an oblate spheroid. Such objects may resemble true spheres, but they're somewhat squashed. Take Earth. The radius of our pl...
The interior of the Earth, like that of the other terrestrial planets, is divided into layers by their chemical or physical (rheological) properties, but unlike the other terrestrial planets, it has a distinct outer and inner core. The outer layer of the Earth is a chemically distinct silicate...
The two rocky planets are also roughly the same distance from the sun, and both have an atmosphere. While Venus’s cold and unpleasant landscape does make it seem far less like Earth, scientists recently detected another striking similarity between the two, the presence of active volcanoes. ...
