Oldest male dolphin in the US dies at California park at 54

  Oldest male dolphin in the US dies at California park at 54 Semo, the oldest known male bottlenose dolphin in the United States, has died at a Northern California theme park where he was a fan favorite.The San Francisco Chronicle says Semo died Tuesday at age 54.

New research published in Nature Astronomy shows that the sun will form a planetary nebula, settling a debate over what happens when stars like our own die . No one is writing its obituary just yet, but scientists have long known that the sun will die — and now we know what will happen next.

No one is writing its obituary just yet, but scientists have long known that the sun will die — and now we know what will happen next.

New research by an international team of astronomers shows that once it exhausts its hydrogen fuel in 5 billion years or so, our host star will morph into an enormous ring of glowing dust and gas — what astronomers call a planetary nebula.

Golovkin uncertain of Alvarez rematch in September

  Golovkin uncertain of Alvarez rematch in September Gennady "GGG" Golovkin is uncertain if he will get a rematch against Saul "Canelo" Alvarez in September, according to ESPN. Alvarez will return from his six-month suspension on August 17, which would make him eligible to fight GGG in September. He was suspended in mid-April for testing positive twice for the banned substance clenbuterol.

There are only two things guaranteed in life; death and taxes, and that goes for the sun too (well, minus the taxes). Yes, the big star in the sky will eventually die - but up until now , no one actually knew what would happen after it perished.

"Planetary nebulae are among the prettiest objects in the night sky," Dr. Albert Zijlstra, a professor of astrophysics at the University of Manchester in England and a member of the team, told NBC News MACH in an email. "It is nice to know that the sun will, one day, also make one, even if we won't be around to enjoy it!"

Zijlstra said the nebula will form out of an "envelope" of dust and gas ejected by the dying sun, which by then will have swollen to become a red giant that extends all the way out to the orbit of Venus and perhaps beyond. After making the ejection, the sun will heat up while shrinking down into a white dwarf roughly the size of Earth but much denser.

The nebula will be visible for 10,000 to 20,000 years — a blink of an eye on the cosmic time scale. Its gas and dust will slowly disperse, eventually providing the raw material for a new generation of stars and planets.

Michelle Obama on 2016 election: 'What is going on in our heads where we let that happen'

  Michelle Obama on 2016 election: 'What is going on in our heads where we let that happen' Michelle Obama on Saturday discussed the 2016 presidential election at the United State of Women summit, during which she said she is still reflecting on the outcome and asking how "we let that happen." "In light of this last election, I'm concerned about us as women and how we think," she said at the event. "What is going on in our heads where we let that happen, you know?"The former first lady was discussing encouraging young wo men to dream big, and how to reflect on standards for women after Democratic candidate Hillary Clinton lost the election and the United States didn't elect its first woman president.

The new finding, published May 7 in the journal Nature Astronomy, seems to settle a longstanding debate over the sun's distant future.

It's long been known that most stars wind up producing a planetary nebula, but astronomers thought the sun — a ball of superheated gas with a diameter 109 times that of Earth — was too small to form a visible nebula.

"The data said you could get bright planetary nebulae from low mass stars like the sun," Zijlstra said in a written statement. "The models said that was not possible, anything less than about twice the mass of the sun would give a planetary nebula too faint to see."

For their new research, the astronomers created a series of computer models that show how quickly dying stars heat up after ejecting their envelopes. The models indicate that stars heat up three times faster than previous models indicated, showing that there's still enough heat from stars the size of our sun to light up a nebula.

"Our understanding of the sun's fate has ping-ponged back and forth," Dr. Karen Kwitter, an astronomy professor at Williams College in Williamstown, Massachusetts, told MACH in an email, adding that "now, these newest models say that yes, the sun will produce a planetary nebula."

She called the new finding a "'win' for the little guy."

The nebula our sun produces won't be as bright as the ones produced by bigger stars. But as Zijlstra told The Guardian, "If you lived in the Andromeda Galaxy two million light-years away, you'd still be able to see it."
