Black Holes 10 billion times bigger than the Sun discovered

Giant Black Hole

Astronomers report that they have discovered the most gigantic black holes ever found in the universe, an abyss 10 times the size of our solar system, encompassing regions or “event horizons” about five times the distance from the sun to Pluto or about 2,500 times as massive as the black hole at the center of the Milky Way.

First Alien Planet In Habitable zone


This artist’s conception illustrates Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone — the region around a star where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our sun.

Crescent Moon and airliner

Moon and airplane

This slender crescent Moon was recorded at a tender age of 34 hours and 18 minutes.

Our Sun is more active now than it has been for the past four years. Increasingly, energetic particles and radiation are being ejected toward the Earth, posing significant hazards for our spaceborne and ground-based infrastructure. Next year will see the start of ESA’s precursor space weather warning services under the SSA Preparatory Programme. Credits: ESA
