India lofts a record 104 spacecraft on a single rocket
Credit: ISRO An Indian rocket deployed 104 spacecraft into orbit 300 miles above Earth on Tuesday, the largest flock pack of satellites ever launched on a single booster. The satellites from India, the United States, the Netherlands, Switzerland, Israel, Kazakhstan and the United Arab Emirates will take pictures of planet Earth, monitor the environment, validate new technologies, and serve as tools in the education and training of future aerospace engineers. The smooth flight notched 38 straigh..>> view originalWant To Discover An Exoplanet? Here's Your Chance
NASA’s Kepler Space Telescope may be the most well-known instrument helping astronomers in their hunt for alien planets, but it is far from the only one. Another such instrument is the W.M. Keck Observatory in Hawaii, which has, using the High Resolution Echelle Spectrometer (HIRES) mounted atop its 10-meter telescope, made over 61,000 individual measurements of over 1,600 stars over the past two decades. This treasure trove of data, which contains clues to the existence of over 110 potential ..>> view originalAstronomers spot last gasps of dying star
February 14, 2017 —What ends with a bang might start with a sputter, according to astronomers.A new paper published Monday in Nature paints the most complete picture yet of a giant star's end-of-life process. Captured a mere six to ten hours after the start of a violent supernova, images of lingering stellar material surrounding the star reveal hints of what the supergiant was doing during its final year of life.While the core collapse that triggers this kind of supernova is common, the trick i..>> view originalAn Enormous Exoplanet Is Having a Strange Influence on Its Star
Illustration: ESO/L.Calcada There’s a star about 370 light-years from here that’s pulsating in response to its unusually heavy planetary companion. It’s the first time that astronomers have seen this sort of interaction between a planet and its host star. “We thought that planets cannot really excite their stars, but we find that this one does.”A new study published in Astronomical Journal Letters is the first to document planet-induced pulsations in a stellar object. The star, dubbed HAT-..>> view originalSuper Earth Capable Of Supporting Life, Scientists Claim
There is a super-Earth existing outside the solar system near our planet. This must be good news when efforts are underway to colonize Mars. This was revealed in the Lick-Carnegie Exoplanet Survey by a team of international scientists. It was led by astronomers Steve Vogt, Geoffrey Marcy from the University of California, and Carnegie Institute of Science's Paul Butler at Washington. The team discovered 60 new planets and 54 potential planets outside the solar system making a total of 114 new p..>> view originalAncient Judean Jars Offer Insights Into Earth's Magnetic Field Strength
In ancient Judea, potters often created jars big enough to hold wine or olive oil and sent them to kings as tax payment. Even as rulers came and went over the years, potters kept making the same ceramic jars. Little did they know, however, that their creations would someday contribute to science. Indeed, these 3,000-year-old ancient jars provide some clues into the strength of Earth's magnetic field, a new study in Israel revealed. It's as if the jars themselves hold records of the waning and f..>> view originalSea ice hits record bows at both poles
Arctic temperatures have finally started to cool off after yet another winter heat wave stunted sea ice growth over the weekend. The repeated bouts of warm weather this season have stunned even seasoned polar researchers, and could push the Arctic to a record low winter peak for the third year in a row.Meanwhile, Antarctic sea ice set an all-time record low on Monday in a dramatic reversal from the record highs of recent years.

Industrial pollution has reached even the most remote corners of Earth: the deepest part of the sea.Scientists have discovered “extraordinary levels” of polychlorinated biphenyls, or PCBs, in the Mariana and Kermadec trenches, two of the deepest ocean chasms on the planet. “Trenches have been considered as pristine environments, but also (given their locations and topography) as likely sinks for contaminants that enter the marine environment,” Alan Jamieson, a marine ecologist at Newcastle Uni..>> view originalEthicists advise caution in applying CRISPR gene editing to humans
