Billy Crystal Reveals the Secret to His 48-Year Marriage

Billy Crystal Reveals the Secret to His 48-Year Marriage Some Hollywood marriages crumble — but not for Billy Crystal and his wife, Janice Crystal. The Emmy winner opened up to Us Weekly exclusively about the secret to his 48-year marriage. Celebrity Couples and How They First Met “We laugh a lot,” Billy, 70, told Us during a Friars Club event in his honor at New York City’s Ziegfeld Ballroom on Monday, November 12. “We’ve grown together, we’ve parented together, we’ve grandparented together. I’m lucky that I found the person when I was 18.” The Soap alum acknowledged that his advice isn’t necessarily a secret, but he thinks his union with Janice, 69, works because they simply “just keep listening to each other.

But when the Sun dies , it will turn into an enormous crystal ball, according to a new study. When stars die , they eventually become white dwarfs and new evidence has found that white dwarfs eventually Further analysis and modeling suggested that the odd "pile-up" is due to the crystallization process.

When the Suns supply of helium is nearly depleted it will become completely unstable and start a series of thermal pulses. Within time these pulsations will blast away its outer layer until all that is left is an object about the size of Earth and is called a white dwarf. Surrounding the white dwarf will be a

Like all stars, our sun began in a nebula, where gas and dust collapsed on itself in a flurry of cosmic friction. Building pressure and heat created nuclear fusion, which ignited the star into shining. Hydrogen fused into helium, and for billions and billions of years, the center of our solar system has blazed on.

Eventually, though-in about five billion years-the hydrogen, its fuel source, will run low and heavier elements will begin to fuse. This will build pressure and cause the sun to expand and engulf the orbits of its neighboring planets, Mercury, Venus, and Earth. Now a Red Giant and highly unstable, our sun will emit enormous pulses of plasma and gas. As it blasts most of its matter off into space, it will transform into a huge fluorescent nebula before collapsing into a mere speck of its former self: a cold, dense white dwarf.

Kranjec profits from Hirscher errors to win giant slalom in Saalbach

Kranjec profits from Hirscher errors to win giant slalom in Saalbach Slovenian skier Zan Kranjec took advantage of a rare off day for Marcel Hirscher to claim his first World Cup win in the giant slalom at Saalbach on Wednesday. Hirscher, who was fifth after the first run, made three big errors on his second run and failed to finish among the first three, ending sixth. It ended a run of 18 consecutive podiums in the giant for the Austrian who has won five crystal globes in the discipline. "Either I have forgotten how to ski in the last two days or there is another problem," said Hirscher. "You can see how quickly you can go from hero to zero. I skied like I did at Alta Badia.

The sun will turn to ROCK in 10 billion years’ time: Star will burn the last of its nuclear energy and become a ' crystal ball' 200,000 times Experts found white dwarf stars form metallic oxygen and carbon crystal cores. Crystallisation delays cooling, stars could be billions of years older than thought.

The sun is going to die and take the Earth with it. Here's how. Once the sun becomes a giant , the habitable zone will move out to between 49 and 70 astronomical units. Neptune in its current orbit would probably become too hot for life; the place to live would be Pluto and the other dwarf planets

It’s what happens next that fascinates Pier-Emmanuel Tremblay, a physicist at the University of Warwick in England, whose paper, published this week in the journal Nature, examines what happens to these star corpses, or “stellar embers."

For one, they become unimaginably dense, “200,000 times denser than Earth.” (Scooping a spoonful of white dwarf would be like hefting a helicopter in one hand.) Over billions of years, they transition from a liquid to a solid. The larger the dwarf, the quicker the transition. But unlike the liquid in your ice tray freezing into cubes, the oxygen and carbon that make up a white dwarf start crystallizing at 18 million degrees Fahrenheit.

The cooling process takes so long because the crystallizing dwarf cores emit heat, which changes their color and luminosity, creating a visual effect the researchers describe as a “pile-up” of stars. It’s not an actual pile-up though. When looking at objects as far away as 330 light-years from the sun, there’s a good chance you’re looking at light that has already been snuffed out.

Hirscher storms to Saalbach slalom success

Hirscher storms to Saalbach slalom success Marcel Hirscher stormed back from a rare reverse the day before to win the World Cup slalom at Saalbach in his native Austria on Thursday. The defending seven-time alpine skiing Crystal Globe holder had trailed in only sixth in Wednesday's giant slalom, to end a run of 18 consecutive podiums in the discipline. But the 29-year-old put that error-marred performance behind him to register his fifth win of the season and 63rd of his career to extend his lead in the overall World Cup standings. Leading after the first run he notched up his 30th slalom success by coming in 0.

" The sun itself will become a crystal white dwarf in about 10 billion years." Tremblay and his colleagues analyzed data gathered by the European White-dwarf crystallization is akin to water freezing from liquid to ice. But the material in this case is oxygen and carbon, and it ' s crystallizing at

When the sun reaches this late stage in its stellar evolution, it will lose a tremendous amount of mass According to Schroder and Smith, when the sun becomes a red giant star in 7.59 billion years, it will Our solar system sure seems like an orderly place . The orbits of the planets are predictable

Thanks to the European Space Agency’s Gaia spacecraft, which has been charting star positions in the Milky Way since 2013, Tremblay and his team were able to analyze 15,000 white dwarfs at varying stages of their cooling evolution. Their work offers the first evidence that white dwarfs indeed solidify into crystals. The findings also suggest that some of these star corpses are 15 percent older than originally thought.

Understanding the gravitational energy release of dying stars and how it slows their cooling could help us determine the age of other stars. Thankfully, the star that makes life on Earth possible has about 10 billion years to go before shrinking into a crystallized hunk of matter.

Kristoffersen wins giant slalom, Hirscher must wait for globe.
Norwegian Henrik Kristoffersen won a third straight giant slalom when he edged compatriot Rasmus Windingstad in Kranjska Gora on Saturday, a result that prevented Marcel Hirscher sealing the overall title.
