A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere. Scientists have been searching for answers to why this vast water supply... Continue reading

A caravan moves across the Lee Adoyta region in the Ledi-Geraru project area near the early Homo site. The hills behind the camels expose sediments that are younger than 2.67 million year old, providing a minimum age for the LD... Continue reading

"The existence, or not, of GJ 581d is significant because it was the first Earth-like planet discovered in the 'Goldilocks'-zone around another star and it is a benchmark case for the Doppler technique," said Guillem Anglada-Escudé, of Physics and Astronomy... Continue reading

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, spotted four images of a distant exploding star. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive... Continue reading

"Nobody really understands how life got started on Earth," says Scott Sandford, a space science researcher at NASA Ames. "Our experiments suggest that once the Earth formed, many of the building blocks of life were likely present from the beginning.... Continue reading

A handful of new stars are born each year in the Milky Way, while many more blink on across the universe. But astronomers have observed that galaxies should be churning out millions more stars, based on the amount of interstellar... Continue reading

The ‘Standard Model’ of particle physics successfully describes the smallest constituents of matter. But the model has its limitations – it does not explain the dark matter of the universe. Christoffer Petersson, a research scientist at Chalmers University of Technology,... Continue reading

Four hundred years ago, the astronomer Galileo's discovery of Jupiter's four large moons forever changed humanity's view of the universe, helping to bring about the understanding that Earth was not the center of all motion. Today one of these Galilean... Continue reading

Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system, thanks to researchers at MIT. Researchers in the Department of Earth, Atmospheric, and... Continue reading

"It is the first time dust has been discovered in one of the most distant galaxies ever observed - only 700 million years after the Big Bang. It is a galaxy of modest size and yet it is already full... Continue reading

"This experiment demonstrates that, for the first time ever, we can film quantum mechanics - and its paradoxical nature - directly," says Fabrizio Carbone of Ecole Polytechnique Federale De Lausann. In addition, the importance of this pioneering work can extend... Continue reading

A team of astronomers, led by Darach Watson, from the University of Copenhagen used the Very Large Telescope's X-shooter instrument along with the Atacama Large Millimeter/submillimeter Array to observe one of the youngest and most remote galaxies ever found. They... Continue reading

Most people, at some point in their lives, have dreamt of being able to fly like Superman or develop superhuman strength like the Hulk. But few know that we humans have a "superpower" of our own, which almost anybody can... Continue reading

The cavities shown in the image of galaxy cluster MS0735 above were created by jets of charged particles ejected at nearly light speed from a supermassive black hole weighing nearly a billion times the mass of our Sun lurking in... Continue reading

"This new concept is, potentially, as drastic an enlargement of our cosmic perspective as the shift from pre-Copernican ideas to the realization that the Earth is orbiting a typical star on the edge of the Milky Way." Sir Martin Rees,... Continue reading

"The most exciting possibility is that the missing photons are coming from some exotic new source, not galaxies or quasars at all," said Neal Katz of the University of Massachusetts at Amherst. For example, the mysterious dark matter, which holds... Continue reading

The Curiosity robot confirms methane in Mars' atmosphere which may hint that life may have existed. An article published in Science confirms the existence of methane fluctuations in the atmosphere of Mars, as a result of the detailed analysis of... Continue reading

A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell University researchers. Taking a simultaneously imaginative and rigidly scientific view, chemical engineers and astronomers... Continue reading

One of the biggest mysteries in galaxy evolution is the fate of the compact massive galaxies that roamed the early Universe. “When our Universe was young, there were lots of compact, elliptical-shaped galaxies containing trillions of stars,” says Alister Graham... Continue reading

While Einstein's theories predict the existence of gravitational waves, they have not been directly detected. But the ability to "see" gravitational waves would open up a new window to view and study the universe. New research by an astrophysicist at... Continue reading

The MUSE instrument on ESO's Very Large Telescope has given astronomers the best ever three-dimensional view of the deep Universe. After staring at the Hubble Deep Field South region for only 27 hours, the new observations reveal the distances, motions... Continue reading

Astronomers have found a huge black hole which was powering the brightest object in the early universe. The black hole's mass is 12 billion solar masses, and the surrounding quasar pumped out 10^15 times the sun's energy. An international team... Continue reading

Since the late 1990s astronomers have been convinced that something is causing the expansion of our Universe to accelerate. The simplest explanation was that empty space – the vacuum – had an energy density that was a cosmological constant. However... Continue reading

“Finding objects like Kks3 is painstaking work, even with observatories like the Hubble Space Telescope," said Dimitry Makarov, of the Special Astrophysical Observatory. "But with persistence, we’re slowly building up a map of our local neighborhood, which turns out to... Continue reading

High-energy jets powered by supermassive black holes can blast away a galaxy’s star-forming fuel -- resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet little or no hydrogen gas available to create new ones. But... Continue reading
