In gravitational microlensing, distant planetary systems may be discovered by utilizing them as naturally occuring lenses. Efforts to find planets by this technique began in the 1990s. The first definitive detection of an extrasolar planet by microlensing was made in 2003 in the event OGLE 2003-BL...
And then there's nothing physical at the other focus point. It's just sort of a mathematical point right there. So, the center of this ellipse is basically divided into 2 axes. Now, the major axis is always going to be the long one here, and this long axis is cut into sort of ...
Planinly put, is the only effective medical intervention to safeguard our children from some of hte deadliest and most virulent diseases known to man ( PASSAGE 2) let us dispense entirely with the fallacies and the delusion, there is not an analytically credible source on the planet that will...
This thesis uses the first planet discovered with MEarth, the warm 2.7 Earth radius exoplanet GJ1214b, to explore the possibilities that planets transiting M dwarfs provide.关键词: Astrophysics Astronomy Super-Earth and Sub-Neptune Exoplanets| a First Look from the MEarth Project HARVARD ...
阅读理解 There was great excitement on the planet of Venus this week.For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was d
Astronomers have discovered a charming coincidence of mathematics in the heavens: An exoplanet that orbits its star every 3.14 days. The Earth-sized planet has been dubbed the "pi Earth" due to its orbiting period being close to the mathematical constant of pi (π). ...

N-body simulations taking into account standard type-I planetary migration suggest that protoplanets are captured into mean-motion resonant orbits ...
Using a telescope the size of the planet, astronomers have captured the first image of this space oddity. Here's why that matters.
“The logic of non-Western science: mathematical discoveries in medieval India” by David Pingree 2003 Medicine: The Chinese pilgrim Fa Hsien (ca. 337–422 AD) wrote about the health care system of the Gupta empire (320–550) and described the institutional approach of Indian ...
The team discovered that around 450-million years ago a switch enabled plants to delay reproduction and displace new cells downwards from the shoot tips, paving the way to plant diversification. Using cutting-edge developmental and genetic techniques, the team studied the swollen reproductive structures...
