Washington, June 9 : A new study has solved a century-old enigma of the origin of a prehistoric marine massive bonebed in southern California, US.

The study was led by Nick Pyenson, a post-doctoral fellow in the UBC (University of British Columbia) Department of Zoology.

The Sharktooth Hill bonebed is exposed over approximately 100 sq. kilometres of land, located at the southern end of the Central Valley of California.

Washington, June 9 : Researchers at Rensselaer Polytechnic Institute, US, have developed a new method for using computer graphics to simulate and render an accurate visualization of a lunar eclipse, whether in the past or in the future.

The model uses celestial geometry of the sun, Earth, and moon, along with data for the Earth's atmosphere and the moon's peculiar optical properties to create picture-perfect images of lunar eclipses.

Washington, June 9 : Scientists from Ohio State University have found a way to measure distances to objects three times farther away in outer space than previously possible, by discovering that a rare type of giant star could make an excellent signpost for distances up to 300 million light years and beyond.

Washington, June 9 : An international team of astronomers has found most dark gamma-ray bursts occur in normal galaxies detectable by large, ground-based optical telescopes.

Gamma-ray bursts are the universe''s biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away.

Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light.
