A closer look at a star once thought to hold no more mysteries reveals a treasure trove of exoplanets.
An international team of researchers and astronomers have found what could be the motherlode of habitable exoplanets in a nearby star system. According to a new examination of the data, researchers believe the nearby star Gliese 667C -- found just 22 light years away in the constellation Scorpius -- hosts six planets. That's twice as many bodies as the star was thought to be home to, but that's not the big news. The big news is that three of the planets orbiting Gliese 667C are thought to be in the habitable zone, capable of hosting liquid water, and possibly able to support life.Read More
An epic tale of space history is just coming to light, as new images pieced together by several different telescopes around the world and in space show that the galaxy cluster Abell 2744, more colloquially known as Pandora's Cluster, was formed by a massive cosmic collision of at least four separate galaxy clusters.The cluster's history is both complex and violent, with the extreme crash that brought the galaxy clusters together occurring over a span of 350 million years. The galaxies themselves make up less than 5 percent of the mass of the cluster itself. The gas, which makes up around 20 percent, is emitted as X-rays (shown in the above image in red). The remaining 75 percent of the cluster is made of dark matter (shown in the image in blue). Dark matter does not emit, absorb, or reflect light so the best way to detect its presence is by tracking its apparent gravitational attraction. Read More
What does the night sky look like from Earth's point of view? It seems like an obvious question since well, we are on Earth and capable of looking up. But what the night sky looks like as the Earth rotates over time is a particular point of view not often captured on film. Most time lapse footage of the night sky shows the sky and stars moving above Earth, rather than Earth moving below.
But now, YouTube user bulletpeople has taken footage by Stephane Guisard and Jose Francisco Salgado shot at the Very Large Telescope (VLT) observatory and modified it so that the Earth itself moves. The VLT is located in the Cerro Paranal, II Region of Chile and is home to four of the largest optical telescopes in the world. The modified video lets users see what the night sky would look like from Earth's point of view, sped up over time.Read More
