‘Waterworld’ planet found

An astronaut attempting to visit recently discovered planet GJ1214b would land in hot water — literally, US scientists say. Researchers at the Harvard-Smithsonian Center for Astrophysics said they have identified an entirely new kind of planet, dominated not by rock, gas or other common materials, but water. The planet is “a waterworld enshrouded by a [...]

Milky Way humming in mysterious haze

A European space observatory has discovered previously unknown islands of star formation and a haze of microwave radiations in our galaxy, the source of which is a complete mystery. The Planck space observatory was launched in 2009 to analyse small fluctuations in the omnipresent cosmic microwave background (CMB) – complementing data gathered by NASA’s Wilkinson [...]

‘Sloshing’ galaxy cluster discovered

Scientists have spotted vast clouds of hot gas ‘sloshing’ in Abell 2052, a galaxy cluster situated nearly 480 million light years from Earth. The scientists are studying the hot (30 million degree) gas using X-ray data from NASA’s Chandra X-ray Observatory and optical data from the Very Large Telescope to see the galaxies. “The X-ray [...]

Distant faint ‘satellite galaxy’ discovered

Astronomers have discovered a faint “satellite galaxy” 10 billion light years from Earth, and it is believed to be the lowest-mass object ever detected at such a distance. The discovery could help astronomers find similar objects and confirm or reject theories about the structure of the cosmos. Theory predicts that galaxies should be surrounded by [...]

Most distant galaxy produces 100 suns per year

Astronomers have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. Astronomers, including the University of California, Riverside’s Bahram Mobasher and his graduate student Hooshang Nayyeri, made the discovery using NASA’s Spitzer and Hubble space telescopes. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found [...]

Hints of ‘building blocks of life’ detected on Pluto

Planetary scientists claim that the Hubble telescope has found hints of “building blocks of life” on Pluto. An international team, led by the Southwest Research Institute in Colorado, says the Hubble has actually detected hints of complex hydrocarbon molecules, crucial to the first life on Earth, on the surface of the dwarf planet Pluto. The [...]

Fastest-rotating star spins at 600 km per second!

Scientists have for the first time discovered the fastest-rotating massive star, which spins at the speed of 600 kilometers per second at the equator and could be the progenitor of some of the brightest explosions in the universe: gamma-ray bursts. The rotational velocity is so high that the star is nearly tearing apart due to [...]

18 new Jupiter-like planets discovered

Using twin telescopes at the Keck Observatory in Hawaii, astronomers have discovered 18 new Jupiter-like planets orbiting massive stars. Researchers at the California Institute of Technology (Caltech), surveyed about 300 stars, and focussed on those dubbed “retired” A-type stars that are more than one and a half times more massive than the sun. These stars [...]

Planets hold billion of tonnes of diamonds

Recent findings have revealed that some stars in the Milky Way could be harbouring carbon super earths — gigantic planets completely bereft of life but potentially holding billions of tonnes of diamond. The finding comes from a lab experiment at Ohio State University, where scientists recreated the temperatures and pressures of earth’s lower mantle to [...]

‘Bullet-proof’ facts of past water found on Mars

A NASA rover scouting for signs of past water on Mars has found the strongest evidence yet — a vein of gypsum, a mineral deposited by water, protruding from an ancient rock. The rover, called Opportunity, and its twin, Spirit, arrived on opposite sides of Mars in January 2004. Over the years, the rovers, aided [...]
