While recently detected peculiar radio emissions from red dwarf Ross 128 could be from some intelligent alien life, this is unlikely, astronomers say.
O,.,o.
In 1981 astronomer Robert Kirshner made a shocking intergalactic discovery. 700 million light years from the Earth lies an enormous, barren sphere known as the Boötes Void. Its very existence challenges what we know about the universe and its origins. The Void is at least ten times larger than the rules of modern physics say is reasonably likely. As a structure, the Void verges on the impossible.
Yet, this disturbing formation is consistent with Nikolai Kardashevs 1962 theory of advanced alien civilizations and their behavior. Could it be home to a hyper-intelligent extraterrestrial species? A void is a massive region of space that holds either minimal or no galaxies. They are created when mass collapses, and is followed by subatomic particle implosions. With a diameter of 330 million light years, the Boötes Void makes up 0.27% of the observable universe. But according to established scientific understanding its huge size is impossible. The Big Bang theory states that the universe is 14 billion years old, and that it has been expanding exponentially since its birth. Given the age of the universe, there has only been enough time for voids to form that are tens of millions of light years across, not hundreds. Stranger still, is just how empty the Bootes Void is.

New Delhi: Six central forensic laboratories in the country will soon be upgraded for carrying out efficient and scientific investigation in serious and heinous crimes, officials said on Sunday.
The central forensic science laboratories (CFSLs) which will be upgraded with capacity enhancement are located at Chandigarh, Hyderabad, Kolkata, Bhopal, Pune and Guwahati.
“The Ministry of Home Affairs has decided to enhance the capacity of six CFSLs under the Directorate of Forensic Science Services in the area of forensic psychology involving external experts,” an official said.
For his project Marmalade Type, Russian visual artist Rus Khasanov created colorful typography using his camera. The colors seen are due to interference patterns — not a single drop of paint was used in the project.
For a previous project titled Disctortion, Khasanov took CDs and DVDs and destroyed them in various ways (e.g. freezing, tearing, coating, bending). His goal was to see the way the colors and textures react to his alterations.
Jupiter’s core leaves a lot of questions unanswered.
An ancient collision is scientists’ best explanation for the planet’s unusually diffuse core.
Supermassive black holes exist at the center of most galaxies, and our Milky Way is no exception. But many other galaxies have highly active black holes, meaning a lot of material is falling into them, emitting high-energy radiation in this “feeding” process. The Milky Way’s central black hole, on the other hand, is relatively quiet. New observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, are helping scientists understand the differences between active and quiet black holes.
These wildlife bridges don’t just help to create beautiful scenery. They also keep drivers and wildlife safer.
