NASA is adding a cosmic twist to Halloween with an unexpected find by the Hubble Space Telescope: eerie "ghost light" from the remains of a multi-galaxy massacre. As many as six galaxies roughly the size of our own Milky Way met their grisly deaths at the hands of gravity. The celestial bloodbath occurred over a period of 6 billion years in a group of galaxies 4 billion light-years away. Stars from those galaxies, now ripped from their cosmic homes, were seen emitting a "faint, ghostly glow" by the Hubble Space Telescope.
New research shows that this behavioral conformity appears early in human children, but isn't evidenced by apes like chimpanzees and orangutans.
Instead of arriving later by comet impact, Earth's waters have likely existed since our planet's birth.

Understanding how permanent an atmosphere is, where it came from, and most importantly what it is made of are key to understanding if a planet outside our solar system is habitable for life. Our instruments aren't yet sophisticated enough to look at atmospheres surrounding Earth-sized planets, but astronomers are starting to gather data on larger worlds to do comparative studies.

Recent research supports the theory that political ideology - whether someone is a liberal or a conservative - can be transmitted through generations. A new study found that conservatives tend to have more magnified responses to disgusting images, but scientists don't know exactly why.

After decades of struggle, the giant tortoises on one of the islands of Ecuador's Galapagos are thriving thanks to the efforts of conservationists and good governance.
Things such as solar wind, magnetic fields, and geomagnetic storms play significant roles in what we experience here on Earth. We are influenced by the outer space weather conditions more than we think.

Filoviruses, the group of microorganism that include Ebola and the deadly Marburg virus, can be traced back to the Miocene Epoch. This was a period on Earth during which grasslands and kelp gardens first became prominent on the land and sea. Great apes also first evolved during this time, leading to the wide range of primates in the world today. During the period, Ebola and Marburg evolved into separate families of organisms, becoming genetically distinct from each other.

University of Rochester researchers wondered if the red effect - people finding members of the opposite sex more attractive when they are in close proximity to the color red - reflects cultural influences or if there is a more ancient biological basis to it. In many human cultures, the color red is linked to sex and romance. But if the effect is found in other primates, it could reflect a biologically innate sensory bias.
Astronomers have captured the first timelapse images of a thermonuclear fireball exploding out of a nova star, allowing them to track the event as it happens.
