In January 2005, Mike Brown announced the discovery of another object from the Kuiper belt, even larger than Pluto. This dwarf planet (plutoid) provisionally named 2003 UB313 or Xena, was recently officially called, Eris.
We go about our lives unaware that in the depths of space lurk invisible monsters, destroyers, powerful enough to tear apart our sun and leave our Earth a shattered burned-out ruin. We talk about one object out there whose pull is so powerful you can never escape (from it) no matter how fast you go, not even if you travel at the speed of light. We talk about black holes.
Recently, NASA’ Kepler Telescope discovered the smallest three planets found so far in another solar system. Even more interesting is that all three planets — one of them is the size of Mars — are solid planets, like Earth.
Ceres was classified as a dwarf planet, but it’s also considered an asteroid. Discovered on January 1, 1801 by Giuseppe Piazzi, Ceres has a diameter of 950 km and it is by far the largest and most massive asteroid from the asteroid belt, containing one third of the total mass of the asteroid belt.
Researchers from NASA announced that Kepler telescope has made an amazing discovery, a planet similar to Earth, which would be a perfect host to humans. It is the closest planet of this kind discovered so far, it’s located outside our solar system.
Since I was a child I liked the stories about other worlds, other planets. I always imagine another “Earth” full of extraterrestrial life …. When I grew up, I started to follow, particularly, all news about the discovery of new exoplanets.
Astronomers have observed, in a distant galaxy, a black hole (“woke up” from a period of extended inactivity) swallowed a gigantic celestial body in the neighborhood. Experts say that a similar event could happening soon in our own galaxy.
Space telescopes, recently activated by NASA, determined the first rock “potentially dangerous” for us. The new asteroid was first locate by Space Telescope NEOWISE and was named 2013 YP139. It is currently about 27 million miles from Earth and has a diameter of 640 meters, according to The Telegraph.
