Wandering Jupiter accounts for our unusual solar system
Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths—planets larger than Earth but smaller than Neptune. If so, those planets ...
'Virtual nose' may reduce simulator sickness in video games
Virtual reality games often cause simulator sickness – inducing vertigo and sometimes nausea - but new research findings point to a potential strategy to ease the affliction.
Comet probe Rosetta detects the 'most wanted molecule'
ESA's Rosetta spacecraft has made the first measurement of molecular nitrogen at a comet, providing clues about the temperature environment in which Comet 67P/Churyumov-Gerasimenko formed.
Planets in the habitable zone around most stars, calculate researchers
Astronomers have discovered thousands of exoplanets in our galaxy, the Milky Way, using the Kepler satellite and many of them have multiple planets orbiting the host star. By analysing these planetary systems, ...
How can dark matter cause chaos on Earth every 30 million years?
In 1980, Walter Alvarez and his group at the University of California, Berkeley, discovered a thin layer of clay in the geologic record, which contained an unexpected amount of the rare element iridium. ...

The solar system and beyond is awash in water
As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links ...
Complex organic molecules discovered in infant star system
For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, suggesting once again that the conditions ...
Severe solar storm may disrupt power, satellites (Update)
A pair of solar eruptions over the weekend have unleashed a severe geomagnetic storm that could disrupt power and communications on Earth, US officials said Tuesday.
Astronomers solve decades-long mystery of the 'lonely old stars'
Many, perhaps most, stars in the Universe live their lives with companions by their sides – in so-called binary systems. Until recently, however, the ancient RR Lyrae stars appeared, for mysterious reasons, ...
Ants' intruder defense strategy could lead to better email spam filters, biologist finds

A second minor planet may possess Saturn-like rings
There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser extent, rings of gas and dust also encircle Jupiter, Uranus, and Neptune. The ...
Rice can 'borrow' stronger immunity from other plant species, study shows
Like most other plants, rice is well equipped with an effective immune system that enables it to detect and fend off disease-causing microbes. But that built-in immunity can be further boosted when the rice ...
