Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The Earth is constantly bombarded by billions of neutrinos, which zip right through the entire globe,... Continue reading

Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are born. Astrophysicists from Spain and other countries... Continue reading

"Massive dead spheroids contain about half of all the stars that the Universe has produced during its entire life," said Sandro Tacchella of ETH Zurich in Switzerland, lead author of the article. "We cannot claim to understand how the Universe... Continue reading

We can imagine the story of the life behind this image of a human hand print made some 30,000 years ago during the Aurignacian period (30,000–32,000 BP) on the wall of the Chauvet-Pont-d'Arc Cave in southern France. The cave was... Continue reading

This is an approximately real-color image from the Hubble Space Telescope, of galaxy cluster Abell 3827. The galaxy cluster is made of hundreds of yellowish galaxies. At its core, four giant galaxies are smashing into each other. As the topmost... Continue reading

Astronomers have discovered one of the most distant planets known, a gas giant about 13,000 light-years from Earth, called OGLE-2014-BLG-0124L. The planet was discovered using a technique called microlensing, and the help of NASA's Spitzer Space Telescope and the Optical... Continue reading

For the first time dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies made with ESO’s Very Large Telescope and the NASA/ESA Hubble Space... Continue reading

This image of Pluto and its largest moon, Charon, was taken by the Ralph color imager aboard NASA's New Horizons spacecraft on April 9 and downlinked to Earth the following day. It is the first color image ever made of... Continue reading

"There are still a lot of mysteries about Titan, said University of Washington astronomer Benjamin Charnay We still don't know how a thick nitrogen atmosphere formed, where the methane comes from nor how Titan's sand forms. And it is not... Continue reading

After searching out of 100,000 galaxies that the WISE spacecraft could see in sufficient detail, none of them is widely populated by an alien civilization using most of the starlight in its galaxy for its own purposes. "That's interesting because... Continue reading

Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous maps created at this... Continue reading

Every 20 to 30 years, Saturn's atmosphere roils with giant, planet-encircling thunderstorms that produce intense lightning and enormous cloud disturbances. The head of one of these storms—popularly called "great white spots," in analogy to the Great Red Spot of Jupiter—can... Continue reading

About 160 globular clusters have been spotted encircling our galaxy, the Milky Way, mostly toward its central bulge. These clusters are among the oldest objects in the Universe. And since the stars within a globular cluster formed from the same... Continue reading

The conditions on Venus are hard to describe. Many planetary scientists say "Start by imagining Hell and working up from there." It's an environment where words like "over 500 degrees Celsius" get thrown around, and it's flat-out crushed every probe... Continue reading

In one of the most comprehensive multi-observatory galaxy surveys yet, astronomers find that galaxies like our Milky Way underwent a stellar "baby boom," churning out stars at a prodigious rate, about 30 times faster than today. Our sun, however, is... Continue reading

Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered. The results, reported in two papers published in the Astrophysical Journal, have implications for big cosmological questions, such... Continue reading

"Scientists have long suspected that an ocean acidification event occurred during the greatest mass extinction of all time, but direct evidence has been lacking until now, said Matthew Clarkson, of the University of Edinburgh's School of GeoSciences. "This is a... Continue reading

"What if Earth didn't have that protective magnetosphere?" said Glyn Collinson, at NASA's Goddard Space Flight Center. "Is a magnetosphere a prerequisite for a planet to support life? The jury is still out on that, but we examine such questions... Continue reading

ESA’s pioneering Cluster mission is celebrating its 10th anniversary. During the past decade, Cluster’s four satellites have provided extraordinary insights into the largely invisible interaction between the Sun and Earth. Cluster’s four satellites fly in formation around Earth to provide... Continue reading

Within the first 150 million years after our solar system formed, a giant body roughly the size of Mars struck and merged with Earth, blasting a huge cloud of rock and debris into space. This cloud would eventually coalesce and... Continue reading

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery, made with the Atacama Large Millimeter/submillimeter Array (ALMA), reaffirms that the conditions... Continue reading

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground,... Continue reading
