Latest Circumstellar discs Stories
The Subaru Telescope has helped astronomers capture the first vivid infrared image of a distant planet forming from a young star.
A team of U.S. astronomers has discovered what looks to be a large asteroid belt orbiting around Vega, the second-brightest star in the northern sky, NASA officials announced on Tuesday.
According to newly released images from the Hubble Space Telescope, a vast debris belt circling around a nearby star is wider than scientists believe, and the unusual orbit of a planet traveling around that star could be to blame.
A new study, using the capabilities of the Subaru Telescope, has captured a clear image of the protoplanetary disk of the star UX Tau A.
Planetary researchers have a new tool in their artillery when trying to hunt for extrasolar planets. Scientists can now use simulated models developed by a group of scientists of how planets are born, helping the hunt for extrasolar planets.
Most would assume that sugar is an essential part of life, but did you know it is actually considered a building block? Well, astronomers have now found these sweet organic molecules around a distant star.
Despite seventy percent of the Earth’s surface being covered by water, in reality the whole of the planet is only made up of 1 percent water, making it relatively dry compared to the gas giants.
One star pinpointed as a prime location for a planet-forming disk decided enough was enough, and closed-up shop suddenly.
Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...
Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...
Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
Epsilon Eridani -- Epsilon Eridani is a main-sequence star in the constellation of Eridanus (the river). It is often used in science fiction because it is extremely sunlike, and in the fictional Star Trek universe it is the home sun of the planet Vulcan which is home to Mr. Spock. It is the third closest star visible without a telescope. It has 85% of the Sun's mass, almost that much of its diameter, and 28% of its luminosity. It is 10.5 light years from Earth. Its spectrum is...
