Far out: NASA space telescope’s 1st cosmic view goes deep

Our view of the universe just expanded: The first image from NASA’s new space telescope unveiled Monday is brimming with galaxies and offers the deepest look of the cosmos ever captured.
The first image from the $10 billion James Webb Space Telescope is the farthest humanity has ever seen in both time and distance, closer to the dawn of time and the edge of the universe. That image will be followed Tuesday by the release of four more galactic beauty shots from the telescope’s initial outward gazes.
The “deep field” image released at a White House event is filled with lots of stars, with massive galaxies in the foreground and faint and extremely distant galaxies peeking through here and there. Part of the image is light from not too long after the Big Bang, which was 13.8 billion years ago.
“We’re going to give humanity a new view of the cosmos,” NASA Administrator Bill Nelson told reporters last month in a briefing. “And it’s a view that we’ve never seen before.”
The images on tap for Tuesday include a view of a giant gaseous planet outside our solar system, two images of a nebula where stars are born and die in spectacular beauty and an update of a classic image of five tightly clustered galaxies that dance around each other.
The world’s biggest and most powerful space telescope rocketed away last December from French Guiana in South America. It reached its lookout point 1 million miles (1.6 million kilometers) from Earth in January. Then the lengthy process began to align the mirrors, get the infrared detectors cold enough to operate and calibrate the science instruments, all protected by a sunshade the size of a tennis court that keeps the telescope cool.
The plan is to use the telescope to peer back so far that scientists will get a glimpse of the early days of the universe about 13.7 billion years ago and zoom in on closer cosmic objects, even our own solar system, with sharper focus.
Webb is considered the successor to the highly successful, but aging Hubble Space Telescope. Hubble has stared as far back as 13.4 billion years. It found the light wave signature of an extremely bright galaxy in 2016. Astronomers measure how far back they look in light-years with one light-year being 5.8 trillion miles (9.3 trillion kilometers).
“Webb can see backwards in time to just after the Big Bang by looking for galaxies that are so far away that the light has taken many billions of years to get from those galaxies to our telescopes,” said Jonathan Gardner, Webb’s deputy project scientist said during the media briefing.
How far back did that first image look? Over the next few days, astronomers will do intricate calculations to figure out just how old those galaxies are, project scientist Klaus Pontoppidan said last month.
The deepest view of the cosmos “is not a record that will stand for very long,” Pontoppidan said, since scientists are expected to use the telescope to go even deeper.
Thomas Zurbuchen, NASA’s science mission chief said when he saw the images he got emotional and so did his colleagues: “It’s really hard to not look at the universe in new light and not just have a moment that is deeply personal.”
At 21 feet (6.4 meters), Webb’s gold-plated, flower-shaped mirror is the biggest and most sensitive ever sent into space. It’s comprised of 18 segments, one of which was smacked by a bigger than anticipated micrometeoroid in May. Four previous micrometeoroid strikes to the mirror were smaller. Despite the impacts, the telescope has continued to exceed mission requirements, with barely any data loss, according to NASA.
NASA is collaborating on Webb with the European and Canadian space agencies.
“I’m now really excited as this dramatic progress augurs well for reaching the ultimate prize for many astronomers like myself: pinpointing “Cosmic Dawn” — the moment when the universe was first bathed in starlight,” Richard Ellis, professor of astrophysics at University College London, said via email.

Trump takes unconventional approach to communicating to the public about war in Iran

Trump takes unconventional approach to communicating to the public about war in Iran

  • The communications strategy opened Trump to criticism that he hadn’t done enough to explain the rationale and objectives of the war

Typical of an unconventional presidency, the Trump administration waited more than 48 hours to make any live, public communication to the American people about why it had decided to go to war with Iran.
President Donald Trump discussed why he launched the attack prior to a White House ceremony honoring military heroes on Monday but took no questions from reporters. Earlier in the day, Defense Secretary Pete Hegseth and Joint Chiefs of Staff Chairman Dan Caine briefed journalists at the Pentagon.
The two days previous, Trump delivered two pretaped statements that were released on Truth Social, the social media site owned by the president’s media company, and granted telephone interviews to more than a dozen journalists — several of which produced fragmented responses that, to some, clouded as much as they cleared up.
The communications strategy opened Trump to criticism that he hadn’t done enough to explain the rationale and objectives of the war, even as the American military suffered its first casualties. By contrast, Israeli Prime Minister Benjamin Netanyahu, who has teamed with the US against Iran, delivered two statements the day the war began and addressed reporters Monday at the site of a missile attack that killed nine people. The Israeli military has held multiple press briefings each day.
“The American people need a commander in chief, and he has been absent in that role,” Rahm Emanuel, White House chief of staff under President Barack Obama, said on CNN Monday. Emanuel, a Democrat, is contemplating a run for the presidency in 2028.
An unconventional strategy leads to criticism
Peter Baker, chief White House correspondent for The New York Times, wrote on social media that “after Trump launched a new war on Iran, he did not rush back to the White House to make an Oval Office address to rally the nation as other presidents have done. He stayed at Mar-a-Lago to attend a glitzy political fundraiser.”
That post provoked a response from Steven Cheung, White House communications director. “Imagine being a reporter so consumed with Trump Derangement Syndrome that he wants President Trump to mimic the failed policies of the past. The truth is that President Trump spent the majority of his time monitoring the situation in a secure facility, in constant contact with world leaders, and made multiple addresses to the nation that garnered hundreds of millions of views. He also took dozens of calls with reporters.”
The calls included one with Baker’s colleague at The Times, Zolan Kanno-Youngs. Trump’s mobile phone number is known to many of the reporters who cover him, and the president often takes their calls for on-the-spot interviews. Besides The Times, he spoke in the aftermath of the attack to journalists for ABC, CBS, NBC, CNN, CNBC, Fox News Channel, The Atlantic, The Washington Post, Axios, Politico and an Israeli television station.
Most of the calls were brief and marginally illuminating; Politico’s Dasha Burns said Trump answered but said he was too busy to talk. The public couldn’t hear what Trump said in the interviews and was dependent upon what the journalists chose to report on the conversations.
“I spoke to President Trump today and he told me that the operation in Iran is going to go very fast,” Libby Alon, a reporter for Channel 14 News in Israel, wrote about her interview on X. “It’s doing very well, and (will) make the people of Israel very happy, and the people of the world very happy.”
The Times reported that in its six-minute chat, Trump “offered several seemingly contradictory visions of how power might be transferred to a new government — or even whether the existing Iranian power structure would run that government or be overthrown.”
In one of his two conversations with Trump, ABC News’ Jonathan Karl said when he asked about the death of Iranian Ayatollah Ali Khamenei, the president said: “I got him before he got me. They tried twice. Well I got him first.” CNN’s Jake Tapper went on the air minutes after his conversation Monday, saying Trump told him “the big one is coming soon,” an apparent reference to a future attack.
Asked for comment, White House spokeswoman Anna Kelly said: “President Trump is the most transparent and accessible president in American history. The American people have never had a more direct and authentic relationship with a president of the United States than they have with President Trump.”
Hegseth briefing concentrates on friendly reporters
Pentagon reporters learned late Sunday about Hegseth’s briefing. Reporters from The Associated Press, Reuters, ABC, CBS, NBC, CNN, Fox News Channel and Stars & Stripes were permitted into the briefing room, but Hegseth did not call on them. Instead, he took questions from NewsNation and Trump-friendly outlets like the Daily Caller, Daily Wire, One America News and the Christian Broadcasting Network. Most mainstream news outlets left their regular stations at the Pentagon last fall rather than agree to Hegseth’s rules restricting their work.
Hegseth denounced the “foolishness” of people wanting to know details of the operation in advance, such as whether Americans would commit to more than air power, and said the operation would continue as long as it took to achieve objections. He initially ignored NBC News’ Courtney Kube when she called out a question: “President Trump put a four-week time limit on it. Are you saying he’s wrong?”
Later, Hegseth denounced Kube for asking “the typical NBC sort of gotcha-type question. President Trump has all the latitude in the world to talk about how long it might take — four weeks, two weeks, six weeks, it could move up, it could move back. We’re going to execute at his command the objectives he set out to achieve.”
Unlike Pentagon briefings in past administrations, reporters were given assigned seats, with the Trump-friendly outlets seated in front. Jennifer Griffin, Hegseth’s former colleague at Fox News Channel who left the Pentagon with other reporters after not accepting his new rules, was seated in the last row.
