This black hole is huge, even by cosmological standards. The team say at a conservative estimate, it is 40 billion times more massive than the sun. By comparison, the black hole at the center of the Milky Way, Sagittarius A*, is only 4 million times more massive than the sun.
NASA's Curiosity rover continues to amaze with what it has discovered.
Text that explains this plus a short slideshow and short video about this astounding mission that could last several more years.

In the hope of finding a new way to fight malaria, scientists have used a spider gene to genetically engineer a fungus to produce a venom that can quickly kill mosquitoes.
The modified fungus was a highly effective mosquito killer in the first tests mimicking conditions in sub-Saharan Africa, where malaria remains a major public health problem, researchers reported Thursday in the journal Science.

Emerging studies show that air pollution is linked to impaired judgement, mental health problems, poorer performance in school and most worryingly perhaps, higher levels of crime.

An experiment conducted by two scientists injected 40 American alligators with ketamine and set each one up with a set of headphones in order to gain a better understanding of their dinosaur ancestors' auditory systems. The focus of the study was centered on interaural time difference (IDT) - a concept that interprets the gap in arrival time of a sound to each ear.

Birds and whales navigate their migration paths according to our planet's magnetic fields. Why have humans lost the ability to sense this?
No issue. Fortunately, dogs put it to good use by crapping in the proper direction.

Oh, what a view.
Dramatic in-flight video from Virgin Galactic shows the dazzling view Earth from above from the private spaceflight company's SpaceShipTwo vehicle, the VSS Unity, during its historic first flight to space Thursday (Dec. 13) over California's Mojave Desert.

As global warming and doomsday threats continue to expose our vulnerabilities here on Earth, scientists are looking to Mars as a potential refuge for humanity. Mars: Making the New Earth outlines the mission to convert this inhospitable planet into our future home.
This conversion process is known as terraforming, a collection of processes by which a planet is reconditioned to resemble Earth. Currently, Mars is a frozen wasteland incapable of sustaining human life. How do you populate endless planes of red dust and rock into fertile soil and teeming forestation? How can you warm the planet's temperature from its current climate of eighty below zero? Would it be possible to transform its radioactive atmosphere into an oxygen-rich environment where humans can thrive?
These are just a few of the challenges that face planetary scientists here on Earth. NASA scientist Chris McKay is one of the believers. The film follows McKay as he attempts to replicate the conditions on Mars, and determine how much warmer the climate needs to be before trees, grass and other vegetation can begin to grow. He conducts these tests alongside a volcano in Mexico, which stands at a towering height of 18,000 feet. This is the closest approximation we have of the temperature and arid conditions found on the red planet.
It will likely take many generations to produce the ideal conditions by which humanity can exist on Mars, but McKay and others are convinced it can be done. But as eager as they are to populate the planet, their mission does come with a caveat. Even if we can achieve this monumental feat, we must stop to consider whether we should.
The film outlines a potential ethical conflict. What if we discover the presence of life on Mars, even of the microbial variety? Should we invade the functioning bio system of an existing life form, or leave it untarnished by human manipulation? The filmmakers include the opinions of experts from both sides of this debate.
Mars: Making the New Earth dazzles with impressive animations from acclaimed visual artist Dan Mass. These images, and the insights that accompany them, give life to complicated science.
