Icy, harsh and uninhabitable — looking at Enceladus, a moon of Saturn, this may be your initial expectation from the cosmic satellite. But take a closer look at this view from NASA's Cassini spacecraft and you might be surprised. "Over the course of the Cassini mission, observations have shown that Enceladus (313 miles across) not only has watery jets sending icy grains into space; under its icy crust it also has a global ocean, and may have hydrothermal activity as well," NASA officals wrote in an image description. "Since scientists believe liquid water is a key ingredient for life, the implications for future missions searching for life elsewhere in our solar system could be significant."
Usually, new administrators at the Environmental Protection Agency (EPA) are welcomed at headquarters without too much fanfare. That is, until today. Scott Pruitt — the new EPA administrator nominated to the position by President Donald Trump — gave
On Sunday, Elon Musk 's SpaceX made history, successfully completing the first commercial rocket launch from the NASA launch pad that also sent astronauts to the moon. The win comes after multiple failures for the SpaceX and Tesla (TSLA) CEO, who wants to change the way people travel and send humans to Mars. Since his childhood, books have played a crucial role in fueling Musk's ambitions.
Feb. 21 (UPI) -- A storage closet at the Royal Ontario Museum in Canada has yielded a new species. The ancient worm fossil has been hiding the closet since the mid-1990s after it was excavated from the Kwataboahegan Formation, a fossil-rich strata in Ontario representing the Devonian period. Analysis of the rediscovered fossil revealed the massive jawed worm to be one-of-a-kind. The 400 million-year-old specimen boasts the largest jaws of its kind. Based on measurements of the worm's jaw and comparisons to related species, scientists estimate the worm would have grown to lengths in excess of three feet. The jawed worm, Websteroprion armstrongi, would have been big and powerful enough to take
South Dakota legislators are weighing whether to let teachers decide how much skepticism to work into lessons on contentious scientific topics such as evolution and climate change. A House committee on Wednesday is set to consider the measure, which would give legal protection to teachers who want to discuss "in an objective scientific manner the strengths and weaknesses" of the subjects. South Dakota is one of at least three states, along with Texas and Oklahoma, considering such a bill.
Even as northeastern Brazil suffers a devastating drought, few remember a grim chapter of a past drought when the government forced mass internment of peasants trying to flee dying farms. The first was in 1915 and the last time was between 1932 and 1933 when the authorities set up what they called concentration camps -- a fairly common term in several countries at the time and yet to be associated with the horrors of Nazi Germany. Fearing the peasants would descend in huge numbers from their parched lands into the city of Fortaleza, the government ordered thousands of families incarcerated in camps with little food, unhealthy living conditions and under guard.
Mars’ two moons, Phobos and Deimos, are small, irregular, but orbit in the same equatorial plane as the red planet. Although they’ve long been thought to be captured asteroids, those orbits would be supremely unlikely. Another possibility would have been if a massive impact created a debris disk, similar to how Earth’s Moon was formed. That alternative creates equatorial orbits, but normally produces at least one very large moon. However, a new simulation was performed, showing how an impact could create three moons around Mars, where the largest, inner one decays, creating Martian system we see today. Our Moon may be what we grew up with, but it’s a cosmic oddity among the rocky planets. Of

A woman in Spain who suddenly became very religious and believed she was speaking with the Virgin Mary turned out to have a brain tumor that appears to have caused her symptoms, according to a new report of the case. Those close to her thought the woman might be experiencing depression, because she was caring for a relative with cancer at the time. After taking a biopsy from one of the lesions, doctors diagnosed the woman with glioblastoma multiforme, a particularly aggressive form of brain cancer.
Here, Khoshnevis tells CNN why he believes humans will soon build on Mars. You're not the first person to suggest building on Mars. What makes your plans better? When I read about the moon and Mars -- the conditions, the habitats -- I realized that almost all of the existing ideas involved taking materials and components from Earth and building with those materials. Taking 1 kilogram of material from Earth to the moon would cost hundreds of thousands dollars. It was clear to me that these ideas were not economically viable. Other approaches, like taking inflatables, also wouldn't work. Inflatables are made of polymeric material, like vinyl, so they won't survive long because the radiation on
The Pentagon is reportedly rushing to develop a drone laser weapon capable of zapping rockets almost as soon as they are launched. According to Las Vegas Review-Journal, the Missile Defense Agency said it has conducted tests of a "directed-energy airborne laser" fired from a military drone – a weapon that would be carried by remote-control aircraft over suspected enemy ballistic missile launch sites. The current system relies on "metal-to-metal" missile interceptors guided by radar and satellites, the outlet reported. "This could revolutionize missile defense, dramatically reducing the role of kinetic interceptors," agency spokesman Christopher Johnson told the outlet in an email. Johnson said
To help us gain a better understanding of air quality around the world, BreezoMeter, an air quality analytics provider, is visually breaking things down with a new interactive air pollution map. The map delivers real-time information on air pollution along with hourly forecasts and helpful weather-related health and fitness recommendations. Its data is drawn from "official air quality sensors" placed across cities that monitor airborne particles and combined with information on wind, weather and traffic conditions.
The clock is ticking to save Central Africa's forest elephants. Within Gabon's Minkébé National Park, poachers likely killed about 25,000 forest elephants for their ivory tusks between 2004 and 2014, according to a Duke University-led study in the journal Current Biology.
A federal appeals court plans to consider arguments over the constitutionality of Ohio's lethal injection process as the state tries to start carrying out executions once again. At issue is whether a contested sedative, midazolam, is powerful enough to put inmates into a deep state of unconsciousness before two subsequent drugs paralyze them and stop their hearts. A related issue is whether Ohio has a realistic chance of finding an alternative drug — a barbiturate called pentobarbital — that once was widely used in executions but has become difficult or, in Ohio's case, impossible to obtain.
A smartphone today packs more computing power than the computers used by NASA in the Apollo space program. At the same time, the Internet of Things is bringing connectivity to a growing number of devices, from smart TVs to fridges. Now researchers at Finland's University of Helsinki want to harness all these computational resources in a project called Ubispark, which uses smart devices for energy-efficient distributed computing. The aim of Ubispark is to create local computing clusters made up of phones and other smart devices that collectively can run large-scale data-processing tasks. "You have connectivity through mobile networks, which is available more widely than the fixed networks you
While most people born in rich countries will live longer by 2030 — with women in South Korea projected to reach nearly 91 — Americans will continue to have one of the lowest life expectancies of any developed country, a new study predicts. Scientists once thought an average life expectancy beyond 90 was impossible but medical advances combined with improved social programs are continuing to break barriers, including in countries where many people already live well into old age, according to the study's lead researcher, Majid Ezzati of Imperial College London. The longevity of South Korean women estimated in 2030 is due largely to investments in universal health care, he said.

The number of people dying from cocaine overdoses in the United States is on the rise, and a new study suggests why: People are using cocaine and opioids together. The study researchers analyzed information on people who died due to drug overdoses in the U.S. from 2000 to 2015, looking at deaths that involved just cocaine as well as those involving both cocaine and opioids. This 2015 increase occurred despite a continued drop in cocaine use since 2006, the researchers said.
For years, Republican lawmakers have tried to scrap NASA's climate change research in favor of space exploration, but with President Trump and his cabinet of climate skeptics now in control, the space agency's earth sciences budget could finally be on the chopping block. Rep. Lamar Smith (R-Texas), the notoriously science-averse chairman of the House Committee on Science, Space and Technology, told E&E News he wants a "rebalancing" of NASA's mission. "By rebalancing, I'd like for more funds to go into space exploration; we're not going to zero out earth sciences," he said. "Our weather satellites have been an immense help, for example, and that's from NASA, but I'd like for us to remember what
February 21, 2017 —If some Members of Parliament lawmakers get their way, satellites will blast off from British soil within three years. A draft “Spaceflight Bill” unveiled Tuesday detailed regulations for a British spaceport that could begin operations as early as 2020. A “Launch UK” conference brought space industry leaders together in London to discuss this possibility. While Britain has sent astronauts and satellites into orbit for decades, it had to partner with the United States, Russia, and other countries for a ride. But as a lucrative new market emerges for satellite launches, some say it’s time for Britain to develop its own launch capability. “We have never launched a spaceflight
Invisible particles washed off products like synthetic clothing and car tyres account for up to a third of the plastic polluting oceans, impacting eco-systems and human health, a top conservationist body warned Wednesday. In its report "Primary Microplastics in the Oceans", IUCN found that in many developed countries in North America and Europe, which have effective waste management, tiny plastic particles are in fact a bigger source of marine plastic pollution than plastic waste.
President Donald Trump has promised to return the U.S. coal sector to its glory days. Experts say that isn't likely to happen, given the nation's shift toward natural gas and renewable energy. But if the coal sector does rebound, it'd be a boon for
Devices that compile, analyze and store electronic information are everywhere. Collectively known as the Internet of Things, the number of devices connected to the internet is already double the number of humans on earth, and these devices are expected to outnumber people 3 to 1 by 2020. Electronically stored information (ESI) from smart appliances, home security systems, fitness trackers and now personal assistants like the Amazon Alexa are compiling a mass of information that is making its way into the U.S. court system. Amazon’s Alexa, introduced to the public for the first time in late 2014, is now a potential witness in an ongoing murder investigation, as investigators believe that Alexa
Disney Research takes us another step toward the day when we'll no longer have to think about charging our devices. While talk of Apple developing wireless technology that will charge your iPhone as it sits in your pocket is merely rumor at this stage, Disney Research has just unveiled the real deal in the form of an entire room capable of charging every compatible gadget that happens to be inside it. As the team points out, current solutions are limited to resting a mobile device on a charging pad and so fail to provide the physical freedom for the kind of charging we’d all like to have. “What we really want is a three-dimensional charging experience where you walk into your living room or office and your cell phone is charged simply by walking in,” said Alanson Sample, one of the researchers who worked on the system.
John Glenn is continuing to inspire 55 years after becoming the first American to orbit Earth. Since Glenn's death on Dec. 8 at the age of 95, untold numbers of devotees have stopped by an exhibit of his artifacts on the campus of Ohio State University, backers have begun fundraising for an observatory and astronomy park in Glenn's name and work has begun on a 7-foot statue in his likeness. For 4 hours, 55 minutes and 23 seconds on Feb. 20, 1962, the capsule circled the Earth three times, making Glenn the first American to orbit Earth.
