Could a Milky Way Supernova Be Visible from Earth in Next...
Astronomers at The Ohio State University have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy...
Scientists generate first map of clouds on an exoplanet
On the exoplanet Kepler 7b, the weather is highly predictable, an international team of scientists has found: On any given day, the exoplanet, which...
Astronomers discover densest galaxy ever
Imagine the distance between the sun and the star nearest to it – a star called Alpha Centauri. That’s a distance of about 4...
Waking up to a new year: Exoplanet orbits its star in...
In the time it takes you to complete a single workday, or get a full night’s sleep, a small fireball of a planet 700...
Voyager 1 Has Left the Solar System
Voyager 1 appears to have at long last left our solar system and entered interstellar space, says a University of Maryland-led team of researchers. Carrying...
Some Nearby Young Stars May Be Much Older
Low in the south in the summer sky shines the constellation Scorpius and the bright, red supergiant star Antares. Many of the brightest stars...
Swift survey finds ‘missing’ active galaxies
Seen in X-rays, the entire sky is aglow. Even far away from bright sources, X-rays originating from beyond our galaxy provide a steady glow in every direction. Astronomers have long suspected that the chief contributors to this cosmic X-ray ba...
New insights into sun’s photosphere reported by NJIT researcher at Big...
NJIT Distinguished Professor Philip R. Goode and the research team at Big Bear Solar Observatory (BBSO) have reported new insights into the small-scale dynamics of the Sun's photosphere. The observations were made during a period of historic in...
Identity parade clears cosmic collisions of the suspicion of promoting black...
10-Dec 2010 What happens when galaxies crash together? For years, these cosmic collisions have been blamed for triggering violent outbursts at the hearts of galaxies. Now, a remarkable piece of detective work has given a verdict: galactic mergers do...
When the black hole was born
Most galaxies in the universe, including our own Milky Way, harbor super-massive black holes varying in mass from about one million to about 10 billion times the size of our sun. To find them, astronomers look for the enormous amount of radiation em...
