Using ALMA telescope, astronomers have observed a huge solar flare on the surface of Mira, one of the closest red giant stars in the night sky about 420 light years away in the constellation Cetus. Read More

First Case Of ‘Cannibal Star’ Discovered By Hubble Telescope

May 24, 2015 |

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“. Read More

What Is The Brightest Star In Earth’s Night Sky?

May 18, 2015 |

By looking at the night sky, you could conclude that the number of visible stars is infinite. But its nothing more false, without a telescope we can see maximum 6,000 stars. Read More

Over Million Young Stars are Forming in a Mysterious Dusty Gas Cloud in Nearby Galaxy

March 20, 2015 |

In a galaxy near our Milky Way, in a hot dusty cloud filled with molecular gases, young stars are being born. This is another proof that the universe is still expanding, and possibilities of life beyond our galaxy is yet to be discovered. Read More

Exotic Newborn Stars found at Edge of Milky Way

February 28, 2015 |

High above the spiral Milky Way, astronomers have spotted two clusters of new stars growing at the fringes of our galaxy. The discovery, led by Denilso Camargo of the Federal University of Rio Grande do Sul in Porto Alegre Brazil, published in the journal Monthly Notices of the Royal Astronomical Society, appears to be the first such stellar cradles found outside the galactic disk.

Astronomers Observe a 4-Star System as it Forms

February 12, 2015 |

Ground-breaking observations have been reported by an international team of astronomers, who is the first to witness the formation of a multiple-star system in its earliest stage. Their findings help support one of several proposed mechanisms by which scientists think these multistar systems might form. Read More

Oldest Stars in the Universe 140M Years Younger Than Previously Thought

February 6, 2015 |

Scientists are always trying to learn more about the universe. Sometimes they are trying to investigate the furthest reaches to look for more possibility of life. But they also continue to examine the origin of the universe. And as they continue to do that they learn more about the formation of our galaxy and our planets. Read More

Remarkably, Astronomy can Explain the Star of Bethlehem

January 8, 2015 | 1

Bright stars top Christmas trees in Christian homes around much of the world. The faithful sing about the Star of Wonder that guided the wise men to a manger in the little town of Bethlehem, where Jesus was born. They’re commemorating the Star of Bethlehem. The one big question for some astronomers every Christmas is what was the light that guided the Magi and is there any astronomical truth to the Star of Bethlehem? Read More

Now, Scientists can Determine Age of Sun-Like Stars from Their Spin

January 6, 2015 |

Turns out Hollywood celebs aren’t the only stars who hide their age well – small cool stars are very good at frustrating astronomers’ efforts to determine how old they are, because they essentially look the same for most of their lives. Read More

Orange Dwarf Star may Visit Our Solar System — Will it be Our Nemesis?

December 31, 2014 | 2

Far beyond the orbit of Neptune, trillions of comets left over from the formation of the solar system lie in wait in a region known as the Oort cloud. Here they are kept in relatively stable orbits around the sun, posing little threat to Earth save for the occasional icy rock that ventures inwards. But in the blink of a cosmic eye that could all change. Read More

Two Blue Giant Stars are Starting to Merge to Create a Megastar

December 15, 2014 | 1

Twins can be close, and that goes for stars as well as people. In some cases, stars get so close that they merge. In an unusual celestial event, astronomers have captured the image of two monster stars that may merge eventually and give us a chance to understand the theory on how supermassive stars are born. Read More

Astronomers Spot Hundreds of Pluto-Size Protoplanets Revolving Around Young Star

December 13, 2014 |

U.S. astronomers using the Atacama Large Millimeter / submillimeter Array have captured a remarkable image of a young star, HD 107146, surrounded by a deep layer of dust — a layer that’s thicker on the outside than it is on the inside, suggesting the presence of an entire family of Pluto-like objects.
