When it came to choosing the exact location of the first tunnel spanning the Bosporus—the narrow strait that divides the European and Asian sides of Istanbul and links the Black Sea with the Sea of Marmara—one of the principal considerations was how to avoid encountering any archeological marvels.
One of the most fundamental questions in astronomy is that of just how many galaxies the universe contains. The landmark Hubble Deep Field, taken in the mid-1990s, gave the first real insight into the universe’s galaxy population. Subsequent sensitive observations such as Hubble’s Ultra Deep Field revealed a myriad of faint galaxies. This led to an estimate that the observable universe contained about 200 billion galaxies.
The new research shows that this estimate is at least 10 times too low.
The GIF as an art form—a short and silent loop—has never been more popular than it is right now. Yet the GIF as a filetype, the way we store the library of ones and zeros that computers translate into animation, is quietly embattled. Behind the scenes, a war to exterminate it has been raging for years, and it never really ended. All these years after Burn All GIFs Day, the GIF remains both deeply flawed and yet strangely irreplaceable. Whether this latest frenzy of GIF popularity enshrines it forever or kills it for good, you can be damn sure we’ll never see anything quite like it again.
A large, almost-blind shark that lives in the freezing waters of the North Atlantic and Arctic oceans is officially the world’s longest-living vertebrate, scientists say.
The Greenland shark (Somniosus microcephalus) has a lifespan of at least 272 years, and might live as long as 500 years1. That is older than the 211-year lifespan of the bowhead whale (Balaena mysticetus), the previous record-holder in the scientific literature2. It also beats the popular — but unconfirmed — tale of a famous female Koi carp called Hanako, who supposedly lived to 226 years old.
Authorities in Dallas used a “bomb robot” to kill one of multiple suspects in a sniping spree that left five police officers dead on Thursday, an unprecedented act in the history of American policing that raises concerns about due process and the use of remotely triggered lethal force by law enforcement.
NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.
