Astronomers have for the first time discovered two alien planets whirling around a pair of stars: a complete solar system with twin suns just like Luke Skywalker’s fictional home world Tatooine. Most stars like our sun are not singletons, but rather come in pairs that orbit each other. Scientists had found planets in these binary…
Roughly 230 million years ago, two mites and a midge got stuck in oozing resin from a now-extinct species of conifer tree in the mountains of northeastern Italy. They never moved again. Despite their ignoble deaths, the insects have now earned the distinction of being the oldest arthropods — invertebrates that include insects, arachnids, and…
The total mass of life on Earth may be one-third less than thought, altering how active we think life on our planet is, researchers say. Past estimates of how much life there is on Earth suggested living organisms store about 1 trillion tons of carbon, of which about 30% dwells in single-celled microbes in the…
Tokyo Institute of Technology researchers have shown simpler versions of the universal genetic code can still function in protein synthesis. In addition to understanding early primordial organisms, the research could lead to applications preventing non-natural genetically modified materials from entering the natural world.
Astronomers have for the first time observed a nova-producing system turn into a supernova, a finding that indicates the universe has more than one way to create a nova. A normal Type Ia supernova is a rare event, occurring perhaps once or twice every century. The type of supernova observed by a team of astronomers…
What ever happened to the Goldilocks planet? It was big news back in September 2010 when a group led by Steven S. Vogt of the University of California, Santa Cruz, and R. Paul Butler of the Carnegie Institution for Science said they had discovered a small planet circling a small red star in the constellation…
Spacetime may be less like beer and more like sipping whiskey. Or so an intergalactic photo finish may suggest. Physicist Robert Nemiroff reached this heady conclusion after studying the tracings of three photons of differing wavelengths that were recorded by NASA’s Fermi Gamma-ray Space Telescope in May 2009. The photons originated about 7 billion light…
Scientists have long suspected that the Sun’s 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. Now, armed with a unique proxy, an international team of researchers show that unusually cold winters in Central Europe are related to low…
This month we are expecting to see a record ice melt in the Arctic. But this is not a world record we can celebrate. This is a wake-up call from planet Earth. The Arctic is home to millions of people, including Inuit whose ancestors first settled thousands of years ago. It is also a unique…
By using novel methods developed for tracing the origins of virus outbreaks, researchers say they have identified present-day Turkey as the homeland of the Indo-European language family. The international team used computational methods analyzing words from more than 100 ancient and contemporary languages, as well as geographical and historical data. By doing so, the scientists…
