Russian billionaire and philanthropist Yuri Milner will devote 100 million dollars (92 million euros) to the SETI project, starting an ambitious ten-year project to detect signals from intelligent alien life in the Milky Way galaxy and beyond.
So far, NASA’ Kepler Space Telescope and other exoplanet survey missions have found thousands of alien planetary systems with nearly 2,000 confirmed exoplanets.
NASA’ New Horizons spacecraft is a mere one million kilometres away from Pluto, as it approaches the dwarf planet and its moon Charon for the historic flyby tomorrow, it’s constantly sending back images to earth, and the last one is the sharpest and most stunning image yet of the mysterious icy world.
It’s a small point in the constellation Ursa Major but if we could cross the 250 light-years that separate us from it, we would observe a rare spectacle: a quintuple star system (five stars) containing two eclipsing binary stars — it is the first known system of its kind.
Astronomers have spotted five monster black holes previously hidden by dust and gas in space and they suggests that there might be millions more of them lurking around our universe.
Using data provided by NASA’s Spitzer Telescope, astronomers suggests that our galaxy may be inhabited by thousands of hot Neptune-sized planets with clouds of helium, an exotic class of planets in our Milky Way galaxy.
The Huge space between galaxies is not completely empty, it is inhabited by some stars which were flung far away from any other galaxies or stars and lost forever in the dark region of intergalactic space. These stars lives in solitude far enough from their nearest neighbors.
Using the Gemini Planet Imager, scientists have discovered a disc-shaped bright ring of debris surrounding a nearby Sun-like star called HD 115600, a planetary system that resembles our own solar system in its infancy. This discovery may help scientists to understand how our solar system formed and developed billions of years ago.
Using Hubble Space Telescope, astronomers have discovered a star never-seen-before in our galaxy or anywhere else in the universe, a star so weird that it was called “Nasty 1“.
When we imagine a habitable planet beyond our solar system we tend to think of a “second Earth”, a twin of our planet which is lies at an ideal distance from its host star — a range of distance from a star where liquid water could exists on the planet’s surface — perhaps a little too hot (desert climate) or too cold (eternal winter). What is often forgotten is that there may exists environmental conditions conducive to life different from what we see on Earth.
This week, astronomers from the Australian National University have discovered a strange gas giant exoplanet (planets beyond our solar system, orbiting a star other than the Sun) that should not exist.
A team of scientists using ground-based telescopes in the USA has discovered a unique planetary system orbiting a neighbor star, HD 7924, a mere 54 light-years away.
