Cruising just above the floor of the Philippine Trench at a staggering 20,300 feet (6,200 meters) below the surface, the young bigfin squid (family Magnapinnidae) became an instant record holder — blowing the previous champ, another bigfin squid swimming about 15,400 feet (4,700 m) below the Pacific Ocean, out of the water.

They are called funerary avenues because tombs are located beside them. While funeral processions could have taken place on them this is uncertain. They would have linked oases together and formed an ancient highway network of sorts, the researchers said.

But their coveted flavor comes at a price: Whoever chops them may soon feel tears running from their burning eyes. But why does slicing onions make you cry?

Here's how to watch it live.]( (Pixabay) You can watch live as a humongous asteroid flies safely past our planet today (Jan. 18). Italy's Virtual Telescope Project, which is based in Rome, will host a livestream starting at 3 p.m. EST (2000 GMT), when asteroid 7482 (1994 PC1) is almost at its closest approach to our planet: 1 million miles or 1.6 million kilometers, closer than it will get for at least 200 years, according to EarthSky. "The Virtual Telescope Project will show it live online, just at the fly-by time, when it will peak in brightness," stated the livestream page, written by project founder Gianluca Masi.

Hurt (IPAC)) Scientists got a close look at an extreme case of seasons thanks to a retired NASA telescope. Researchers used NASA's Spitzer Space Telescope to film a year on an exoplanet called XO-3b. Conveniently, a year on this world lasts only three Earth days. Within that time, the exoplanet experiences a one-day-long summer and a two-day-long winter — and while the seasons pass fast, they're also awfully dramatic.
