Milky Way has a huge void in the middle with no stars in it, scientists find
Our galaxy has a huge, gaping void inside of it that nobody had spotted before. Scientists claim that our understanding of the Milky Way needs a re-evaluation after an international team found a region at the centre of our own galaxy that has no young stars. The Milky Way is made up of many billions of stars, including our Sun. We sit about 26,000 light years from its centre.

A new study could finally explain why our cells rely on DNA, and not its molecular relative RNA, to store and pass on genetic data. The findings show that RNA breaks apart when it tries to incorporate changes — such as chemical damage to the molecule — while DNA can twist and bend its shape to allow for changes.Image via pixabayThe most important thing for any living thing on Earth is to pass on its genes to offspring. Life everywhere feeds, fights and flees all in the hopes that it can eventual..>> view original2015 Set a Frenzy of Climate Records
The warming of the world’s climate has reached a fever pitch in recent years, causing records to fall like dominoes. In 2015, the planet saw a number of such records set, from the hottest global temperature measured to the largest annual increase in carbon dioxide. Those records — along with numerous other indicators of the considerable change wrought on land, in the oceans and air, and to ecosystems — are detailed in the annual State of the Climate Report released Tuesday by the U.S. National O..>> view originalJupiter's Volcanic Moon Io Has a Collapsible Atmosphere
Jupiter's volcanic moon Io boasts an atmosphere made from sulfur dioxide gas รข€” when the satellite is in sunlight. For the first time, researchers have observed the atmosphere during the moon's daily pass through Jupiter's shadow, watching that atmosphere temporarily freeze and collapse.

Nature’s summer fireworks will be even more exciting this year – the annual Perseid meteor shower that arrives during the second week of August will be experiencing what astronomers call an “outburst” this year. This means that stargazers can expect to see more than double the usual number of meteors streaking through the sky on the peak nights of August 11 and 12.“Under perfect conditions, rates could soar to 200 meteors per hour,” said Bill Cooke, of NASA’s Meteoroid Environments Office in Hu..>> view originalExperts Finally Found an Effective Way to Reverse the Negative Effects of Carbon Dioxide on Earth
Aug 03, 2016 07:29 AM EDT Carbon dioxide is a compound found within the earth's atmosphere that is considered to be one of the gasses needed for a continuous life cycle. But having too much of this gas can only bring hazard to Earth if not controlled. Good thing scientists have recently found a way to convert carbon dioxide into something that could benefit both people and nature. Through the study conducted, which was published in the journal Science, the experts from the University of Illi..>> view originalSolving a Mystery of Mammoth Proportions
One of the Best Explanations For Why We Haven't Found Alien Life
So far, the only examples of sentient life we’ve found are right here on our own planet. It’s not for lack of trying, though—we’ve sent out spacecraft deep into our solar system and, so far, still remain alone. What if the problem isn’t where we are looking, though, but when? A forthcoming study in Journal of Cosmology and Astroparticle looks at the possibility that life as we know it may not require a star similar to our sun but could emerge on planets orbiting much smaller, weaker stars. If ..>> view originalMoon Express Approved for Private Lunar Landing in 2017, a Space First
For the first time ever, a private company has permission to land on the moon. The U.S. government has officially approved the planned 2017 robotic lunar landing of California-based Moon Express, which aims to fly commercial missions to Earth's nearest neighbor and help exploit its resources, company representatives announced today (Aug. 3). "This is not only a milestone, but really a threshold for the entire commercial space industry," Moon Express co-founder and CEO Bob Richards to..>> view originalHomes in Wealthier Neighborhoods Tend to Have More Bugs
A few years ago, a team of scientists swept 50 homes in Raleigh, North Carolina for bugs—not the surveillance kind, but the biological one. Armed with headlamps, forceps, nets, and aspirators, they collected every arthropod they could find—every creature with jointed legs and a hard external skeleton, every insect, spider, centipede, springtail, and woodlouse. It was the first systematic census of its kind. And, as I wrote in January, it unveiled a startling amount of diversity. “Each home had b..>> view original
