Are we pointing telescopes in the right direction to find alien life?
In their search for extraterrestrial life on planets similar to ours, perhaps astronomers should look in unexpected places: near aging stars that balloon to epic proportions in their senior years, thereby heating up previously frozen worlds around them, according to new research published in the Astrophysical Journal. Using space- and ground-based telescopes, astronomers usually look at habitable planets around middle-aged stars like our sun, which is 4.5 billion years old. This technique is ba..>> view originalWhat the 'Little Lion' galaxy could tell us about the Big Bang
A faint galaxy shining 30 million light-years away could help scientists learn more about the birth of the universe.Researchers have discovered a galaxy with the lowest level of metals, or heavy chemical elements, ever observed in a star system. Galaxy AGC 198691, nicknamed Leoncino, or “Little Lion,” offers astronomers the chance to see what conditions were like directly after the formation events that caused the universe to form."Finding the most metal-poor galaxy ever is exciting since it co..>> view originalScientists have invented self-spooling 'liquid wire' that acts like spider silk
Get right up close to a spider web, and you'll see some very particular properties: it stays taut in the wind, is really hard to break apart, and any flies coming into contact with it are trapped, rather than bouncing off it. Well, the same sticky substance that traps the flies also helps maintain tension in the web, and now scientists have come up with a way of replicating this in the lab – with a 'liquid wire' that exhibits many of the same properties of webs spun by spiders. So why doesn't ..>> view originalTrump calls for renegotiation of Paris climate deal

When considering locations in the solar system beyond Earth where life could have been sparked, you’d be hard pressed to find a more suitable world than Jupiter’s moon Europa. This moon is thought to be awash with a subsurface ocean protected from space radiation by a thick shell of ice. The ocean is also believed to be salty, containing much of the same chemicals that facilitated life on Earth. Some hypotheses even suggest there’s enough oxygen and nutrients cycling through the water to suppor..>> view originalHow did the giraffe get its long neck?
