You Are Here: Scientists Unveil Precise Map Of More Than A Billion Stars

The European Space Agency has released a chart of the exact positions of many stars in the Milky Way and neighboring galaxies. But the map only shows a small fraction of what’s out there.

Wednesday was the day astronomers said goodbye to the old Milky Way they had known and loved and hello to a new view of our home galaxy.

A European Space Agency mission called Gaia just released a long-awaited treasure trove of data: precise measurements of 1.7 billion stars.

It’s unprecedented for scientists to know the exact brightness, distances, motions and colors of more than a billion stars. The information will yield the best three-dimensional map of our galaxy ever.

“This is a very big deal. I’ve been working on trying to understand the Milky Way and the formation of the Milky Way for a large fraction of my scientific career, and the amount of information this is revealing in some sense is thousands or even hundreds of thousands of times larger than any amount of information we’ve had previously,” said David Hogg, an astrophysicist at New York University and the Flatiron Institute. “We’re really talking about an immense change to our knowledge about the Milky Way.”

The Gaia spacecraft launched in 2013 and is orbiting our sun, about a million miles away from Earth. Although it has surveyed a huge number of stars, Gaia is charting only about 1 percent of what is out there. The Milky Way contains around 100 billion stars

For 7 million stars, Gaia even has measurements showing their velocity as they move toward or away from the spacecraft. “This is just a fantastic new addition,” said Anthony Brown of the Netherlands’ Leiden University, with the Gaia Data Processing and Analysis Consortium.

In 2016, Gaia released some initial results but that was just a tease compared with Wednesday’s massive data dump. Astronomers around the world have been planning how to attack it for months, knowing that discoveries are just waiting in there for the taking.

“Enjoy it,” Antonella Vallenari, another member of the consortium from the Astronomical Observatory of Padua in Italy, said at a news conference as she announced that the data was becoming available.

The European team presented new images of our galaxy based on some initial analyses of the data, along with little movies that simulated what it would be like to fly through the stars. “It’s not fake, it’s real measurements,” Brown said. “We know exactly where the stars are.”

Scientists around the world who were watching the event online struggled to take it all in. “This is like massive scientific progress and we were blinked an image,” said Jackie Faherty, an astronomer at the American Museum of Natural History, one of more than a dozen astronomers who woke up before dawn and gathered together at the Flatiron Institute in New York City to watch.

Then it was time to play, as the scientists bent their heads over their laptops and tried to download data. Researchers are expecting a slew of discoveries in the coming hours and days, but analyses will go on for years and even decades.

“This is the data we’re going to be working on for the rest of my career. Probably no data set will rival this,” Faherty said. “It’s the excitement of the day that we see it. It’s why we were up at 5 a.m. to get here. It’s exciting to be around each other and trying to get the data all at once. It’s a day we’re going to remember.”

Biden Expected To Repeal Military Trans Ban Tomorrow

Published

By

The Biden administration is expected to repeal the ban on transgender Americans from serving in the military, multiple people informed of the decision told CBS News. The announcement is expected as soon as Monday, one senior Defense official and four outside advocates of repealing the ban told CBS News.

The senior Defense official told CBS News the repeal will be through executive order signed by President Joe Biden. The announcement is expected to take place at a ceremony with newly-confirmed Defense Secretary Lloyd Austin, who will order the Pentagon to go back to the policy enacted in 2016 by former Defense Secretary Ash Carter that allowed transgender Americans to serve openly.

The White House did not respond immediately to a request for comment.

The new order will direct the branches of the military to outline an implementation plan. 

The ban was announced by former President Trump via a tweet in July 2017. The ban took effect in April 2019 and barred transgender Americans from enlisting in the military.

In 2014, it was estimated there were around 15,500 transgender military members serving, according to a study by the Williams Institute at the UCLA School of Law.

Biden frequently repeated on the campaign trail his promise to repeal the ban.

Austin said at his Senate confirmation hearing last week that he planned to repeal the ban.

“I support the president’s plan or plan to overturn the ban,” Austin said on Tuesday when asked by Senator Kirsten Gillibrand, “I truly believe, Senator, that as I said in my opening statement, that if you’re fit and you’re qualified to serve and you can maintain the standards, you should be allowed to serve. And, you can expect that I will support that throughout.”

Trump Pardons Steve Bannon In One of His Final Acts As 45th President

Published

By

(CNN)— President Donald Trump has decided to pardon his former chief strategist Steve Bannon, in a last-minute decision made only hours before he is scheduled to depart the White House for a final time.

Officials cautioned CNN that Trump’s decision was not final until he signed the paperwork. Trump told people that after much deliberation, he had decided to pardon Bannon as one of his final acts in office.

Bannon’s pardon would follow a frantic scramble during the President’s final hours in office as attorneys and top aides debated his inclusion on Trump’s outgoing clemency list. Despite their falling out in recent years, Trump was eager to pardon his former aide after recently reconnecting with him as he helped fan Trump’s conspiracy theories about the election.

It was a far cry from when Trump exiled Bannon from his inner circle after he was quoted in a book trashing the President’s children, claiming that Donald Trump Jr. had been “treasonous” by meeting with a Russian attorney and labeling Ivanka Trump “dumb as a brick.” Those statements from Bannon drove Trump to issue a lengthy statement saying he had “lost his mind.”

“Steve Bannon has nothing to do with me or my presidency,” Trump said at the time.Things shifted in recent months as Bannon attempted to breach Trump’s inner circle once again by offering advice before the election and pushing his false theories after Trump had lost.

Since Trump’s election defeat, the President has leaned further into his expansive pardon powers — granting pardons to his first national security adviser, Michael Flynn, longtime ally Roger Stone and former campaign chairman Paul Manafort, among others.

Among Trump’s pardons earlier in his term were those for former Arizona Sheriff Joe Arpaio, right-wing commentator Dinesh D’Souza and financier Michael Milken.

By

(CNN) — California Gov. Gavin Newsom formally submitted the appointment of Alex Padilla to the US Senate today, according to a press release from the governor’s office. 

Padilla formally resigned as Secretary of State this morning and Gov. Newsom also submitted his nomination letter for Assembly member Shirley Weber to replace him. The Deputy Secretary of State, James Schwab, will be the Acting Secretary of State.

“It is fitting that on the same day we celebrate the legacy of Dr. Martin Luther King, Jr. — a civil rights icon who fought for justice and representation — we also move forward the appointment of California’s first Latino U.S. Senator Alex Padilla and the nomination of Dr. Shirley Weber who will serve as the first-ever African American Secretary of State. Both will be strong defenders of our democracy during this fragile moment in our nation’s history,” said Gov. Newsom.

“I am humbled and honored by your trust in me to represent California in the United States Senate. I look forward to continuing to serve the great State of California as a United States Senator and to ensuring that the rights and democratic principles we cherish are protected and preserved for all people,” Padilla wrote in a letter to Gov. Newsom.

Some context: Earlier today, Vice President-elect Kamala Harris formally resigned her seat as one of California’s US Senators. She’ll be inaugurated as vice president on Wednesday, Jan. 20. In a farewell addressed posted to Twitter, Harris said, “Of course, I’m not saying goodbye. In many ways, I’m now saying hello as your vice president.”
