Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred. Light from this blast began arriving at Earth in 2012.Recently, the IceCube Neutrino Observatory at the South Pole found first evidence for a flux of extraterrestrial neutrinos, which was named the Physics World breakthrough of the year 2013. To date, the science team of IceCube Neutrino has announced about a hundred very high-energy neutrinos and nicknamed the most extreme events after characters on the children's TV series "Sesame Street."

Intelligent, Technological Exospecies Likely Evolved Before Us --"And They're Extinct"

Are humans unique and alone in the vast universe? This question--summed up in the famous Drake equation--has for a half-century been one of the most intractable and uncertain in science. But new research shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.

Beyond Einstein --"The Epic Detection of Gravitational Waves May Reveal a Strange Universe" (Thursday's Most Popular)

Cosmologist Latham Boyle with Canada's Perimeter Institute is excited about the unknowns that gravitational waves could now reveal. He explained there was a span of decades between the discovery of radio waves and their use in astronomy.
“For 40 or 50 years, nobody built radio telescopes,” Boyle said. “Finally, when they did, there was a flood of all kinds of crazy discoveries. [There was] the cosmic microwave background radiation, which is kind of a cosmic selfie, then they discovered these things called pulsars, and they discovered quasars. They discovered all this stuff that people would have called you crazy if you’d suggested it before. As soon as you turned it on, it was out there. It’s just a historical fact that often you see wilder stuff.”

Hubble's Heir: James Webb Space Telescope's Golden Mirror Unveiled --"The Largest Yet Sent into Space"

The JWST, the scientific successor to NASA's Hubble Space Telescope, will be the most powerful space telescope ever built.
Scientists from around the world will use this unique observatory to capture images and spectra of not only the first galaxies to appear in the early universe over 13.5 billion years ago, but also the full range of astronomical sources such as star forming nebulae, exoplanets, and even moons and planets within our own Solar System. It’s targeted to launch from French Guiana aboard an Ariane 5 rocket in 2018. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Two black holes in nearby galaxies have been observed devouring their companion stars at a rate exceeding classically understood limits, and in the process, kicking out matter into surrounding space at astonishing speeds of around a quarter the speed of light.

Astronomers Using Light Echos to Solve Mysteries About Alien Planet Formation

For the first time, astronomers used echoes of light to determine the distance from a star to the inner wall of its surrounding planet-forming disk of dust and gas. Astronomers use light echos to study objects so distant that they can't be seen as more than points. In particular, researchers are interested in calculating how far young stars are from the inner edge of their surrounding protoplanetary disks. These disks of gas and dust are sites where planets form over the course of millions of years.

Peering Through the Dust--"Milky Way's Central Region Best Bet for Ancient Habitable Planets" (Wednesday's Most Popular)

Clouds of dust permeate the Milky Way, blocking our view of the galaxy's stars. Today, researchers have a suitable map of our galaxy's spiral structure, but, like early explorers charting new territory, they continue to patiently and meticulously fill in the blanks.

"Only one species of the billions of species that have existed on Earth has shown an aptitude for radios and even we failed to build one during the first 99% of our 7 million year history," observed Charles Lineweaver a noted astrobiologist at the Australian National University.

A Three-Galaxy Mashup Observed Harboring a Monster Supermassive Black Hole

Australians astronomers have announced that they observed a supermassive black hole discovered during a test of CSIRO's new ASKAP telescope, clued by gasses swirling at the center of the galaxy were traveling 600 km per second, twice as fast as would have been expected.The monster object dwarfs anything in our galactic neighborhood, formed from the collision of three galaxies, the massive cluster IRAS 20100−4156, 1.8 million light years from Earth. In vivid contrast, the supermassive black hole at the center of our Milky Way galaxy is around 4.3 million times the mass of the sun. Astrophysicists believe, however, that the largest black holes in the universe may reach 40 billion solar masses or more.

New Hubble Discovery --"Most Dwarf Planets Have Moons"

The Kuiper Belt is a vast reservoir of leftover frozen material from the construction of our solar system 4.5 billion years ago and home to several dwarf planets. Some of these worlds have known satellites, but this is the first discovery of a companion object to Makemake, discovered in 2005, named for a creation deity of the Rapa Nui people of Easter Island.
Makemake is one of five dwarf planets recognized by the International Astronomical Union.
