A European spacecraft is showing us how dynamic the Sun is with newly released images, the highest-resolution images of our star's surface so far. Look (safely) at the Sun's surface in the highest ...
The Kepler orrery is a group of animations created by Daniel Fabrycky and Ethan Kruse, which show exoplanets and stars discovered by the Kepler Space Telescope. 1,815 exoplanets and 726 planetary systems are in the animation.
A new solar telescope in Hawaii has released a series of images of the sun that peer inside the depths of its sunspots and so-called "quiet regions." The sun may be close to 94 million miles away ...
The images, taken on March 22, 2023, and released Wednesday, showcase different dynamic aspects of the sun, including the movements of its magnetic field and the glow of the ultrahot solar corona ...
The star is 1.117 M sun and 1.555 R sun, or 111% the mass of and 155% the radius of the Sun. [5] With a metallicity of .09 (± 0.10) [Fe/H], Kepler-4 is more metal-rich than the Sun, a figure that is important in that metal-rich stars tend to have orbiting planets more often than metal-poor stars. Kepler-4 is also about 6.7 billion years old. [5]
The star is somewhat poor in metals, with a metallicity ([Fe/H]) of about –0.37, or about 43% of the amount of iron and other heavier metals found in the Sun. [2] The star's luminosity is a bit low for a star like Kepler-442, with a luminosity of around 12% of that of the solar luminosity.
The pictures were taken on March 7 when the spacecraft crossed directly between the Earth and Sun.
Kepler-1649 is a type-M red dwarf star estimated to be roughly ¼ the radius of the Sun [10] with only two confirmed planets in its orbit, the other being Kepler-1649b. [11] Kepler-1649b is similar to Venus from our own solar system in two ways: both Kepler-1649b and Venus have orbits roughly half the radius of the next known planets (Kepler ...
