In the past two decades, astronomers have detected more than 2000 exoplanets, the first of these detections were gas giants as massive as Jupiter that are so close to the host that they are heated to high temperature in order of 2,000°C; but now, for the first time, astronomers are getting down to the regime of potentially habitable Earth-like worlds.
On April 18, 2013, NASA’ astronomers announced the discovery of a new planetary system composed of five worlds orbiting a star somewhat cooler and smaller than the Sun, approximately 1,200 light-years away from us in the constellation Lyra.
On Tuesday evening, NASA held an extraordinary press conference announcing Kepler’ last results on exoplanets research: amazingly, the number of known alien planets has just gone up by more than 60%.
Weather here on Earth can be really nasty, but on distant worlds, the atmospheric conditions can be extreme, far beyond anything we saw or imagine. Here’s why you should not go to HAT-P-11b.
Finding a true Earth analog orbiting within the habitable zone of a sun-like star is a sort of holy grail to astronomers and we are about to get a lot closer to detect one in the near future as new incredible inventions and technologies are available to us now.
Our solar system is a huge place, it’s true edge stretches far beyond the Kuiper belt. Maybe, you are familiar with Pluto, the demoted planet and the most famous dwarf planet within the Kuiper belt, but there are too many objects beyond it; actually, there are dwarf planets larger than Pluto residing there.
Over the past two decades, the study of exoplanets has grown more rapidly than any other field of astronomy.
The existence of dark matter in the universe is one of the major puzzles of current astrophysics, cosmology and particles research. While there is clear evidence for the existence of dark matter from astronomical observations, it is still unclear what the physical nature of dark matter is.
At night, when you look at the stars and you wonder “is anybody out there?” just realize that someone out there could be looking back at you and wondering the same.
