  • Vera Rubin, the astronomer whose work first confirmed the existence of dark matter, has passed away at the age of 88. Along with that groundbreaking discovery, Rubin has a legacy of scientific achievements and awards, and was a strong advocate for women in science.
  • Science
    Researchers have discovered that the world’s largest, most famous diamonds were formed in a different part of the Earth’s mantle and through a different process to the smaller, more common diamonds that make up the vast majority.
  • If you grew up knowing that there were nine planets orbiting our sun and were a bit crushed when Pluto lost its status, there might be new hope for a nine-pack, as researchers are again putting forth the idea that a planet might be lurking somewhere out there on the fringes of our Solar System.
  • Far away from our beloved Milky Way lies a galaxy called UGC 1382, a place that scientists and astronomers thought was just another tiny, elliptical galaxy. It turns out that not only is it bigger than they previously thought, but it's also much larger than the galaxy that Earth calls home.
  • It's been believed that gas giants like Saturn and Jupiter have two types of hydrogen in their makeup, but new research using a a laser-heated diamond anvil cell reveals a third form of the element.
  • A chance re-examination of an old astronomical glass plate has shown that the very first evidence of an exoplanetary system was recorded almost 100 years ago, on a glass plate showing the light from a distant star.
  • A new calibration tool developed by researchers at the Carnegie Institute is set to have a big impact in the hunt for exoplanets. The technology allows astronomers to use a longer wavelength of light when analyzing distant stars, making it possible to pick out false positives in results.
  • Scientists have used data gathered by NASA's MESSENGER probe to reveal the secret behind the dark appearance of Mercury's surface, with the results partially contradicting a recently proposed theory on the matter.
  • Science
    Researchers have used data collected by the Carnegie Airborne Observatory to uncover chemical variation in plant life across the lowland Peruvian Amazon. The study provides key information for understanding the rainforest, and assessing our future impact on it.
  • Any given CO2 emission will have its maximum warming effect just 10 years later, new research shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.
  • Science
    Scientists at the Carnegie Institution for Science have synthesized a new zeolite-type form of silicon that can conduct electricity and absorb and emit light more efficiently than the diamond-structured form used in semiconductor technologies, with a plethora of potential real-world applications.
  • A team of researchers, including scientists from MIT and the Carnegie Institution of Science, has analyzed the composition of stars in the fossil galaxy known as Segue 1. The galaxy exhibits unusual features that are allowing astronomers to observe the composition of stars from the early universe.
