How Did Supermassive Black Holes Form In Early Universe? Computer Simulation Provides Answers
Black holes — regions of space-time that are so dense that not even light can escape their gravitational pull — are formed when massive stars (those with over five times the mass of the sun) collapse under their own weight. This process, understandably, takes time, and that is why most supermassive black holes formed comparatively recently in the universe’s 13.8 billion year history.However, there are a few exceptions. In recent years, astronomers have spotted supermassive black holes that forme..>> view originalCuriosity's tires are cracking up on the red planet, NASA images reveal
Breaks have been observed in the wheel's of NASA's Curiosity Mars Rover.A routine check of the aluminium wheels on the rover found two small breaks on the rover's left middle wheel.While the rover has experienced wear and tear, it is expected to complete its mission and has already reached the 10-mile (16 kilometer) mark since landing on Mars in August 2012. Scroll down for videos Two of the raised treads, called grousers, on the left middle wheel of NASA's Curiosity Mars rover broke during the ..>> view originalUQ researchers to set sail with global ocean mapping program
A Swiss yacht on an epic research expedition to map the world’s oceans will host University of Queensland marine scientists on the Great Barrier Reef in March and April. UQ’s Professor Justin Marshall and Dr Chris Roelfsema will lead two research projects as part of the 33m Fleur de Passion’s four-year-long Ocean Mapping Expedition. Dr Roelfsema, of UQ’s Remote Sensing Research Centre, is leading a program to map the habitat of the Great Barrier Reef, focussing on the 200 shallow reefs in the ..>> view originalTurns Out Boiling Liquid Does the Opposite of What You'd Expect on the ISS
Here on Earth, when you boil a liquid, it evaporates and turns into a vapour until it's cool enough to condense again. But astronauts on the International Space Station (ISS) have shown that something else entirely is happening in a microgravity environment. They found that vapour condensed into a liquid, even when the temperature was 160 Kelvin above the substance's normal boiling point - a new phenomenon that's stumped scientists. Previous research has already shown that microgravity has str..>> view originalStephen Hawking Books Ticket To Space To Board Richard Branson's Virgin Galactic Spacecraft
Eminent theoretical physicist Stephen Hawking is soon to board a spacecraft. In a recent interview, the legendary cosmologist revealed that he will be on board Virgin Galactic. According to CBS news, Professor Stephen Hawking said that he has accepted an invitation from billionaire Richard Branson to travel to space. The journey will be organized by Branson's company Virgin Galactic. Stephen Hawking said that he has already undergone a Zero-gravity flight which allowed him to float in simulated..>> view originalDingo DNA Could Hold The Key To Understanding Animal Domestication
A proposal by University of NSW scientist Bill Ballard to study the DNA of a two year old Australian dingo - called Sandy Maliki - has been announced as one of five finalists in the World’s Most Interesting Genome competition. What makes it "most interesting" is that it may uncover what helps a wild animal become domesticated. Dingoes were introduced to Australia about 5000 years ago, with genetic evidence suggesting they originated from East Asian domestic dogs. They bred in isolation unt..>> view originalNasa 'smallsats' open up new planetary frontier

An illustration shows the possible scene on the surface of the planet called TRAPPIST-1f. Illustration by NASA/JPL-Caltech The discovery of alien life would be revolutionary. But what if we uncovered it on two—or even seven—planets all orbiting the same star? That’s the tantalizing possibility offered by the cosmic grouping called TRAPPIST-1, where seven Earth-size worlds circle a star roughly 39 light-years away. According to a new study, those planets are packed so tightly around t..>> view originalSo Now There Are 7000 Methane Bubbles Beneath Siberia
Back in 2016, Siberia’s amusingly named Bely Island made headlines around the world after sections of its grassy landscape became somewhat bouncy. As it turned out, the island was leaking greenhouse gases at a remarkable rate. In fact, the air escaping from the ground there contained 100 times more methane and 25 times more carbon dioxide – the two most potent greenhouse gases by far – than the surrounding atmosphere. This time last year, just 15 of these near-surface, water-coated methane bub..>> view originalPython devours hare near Queensland school classroom
