M27: The Dumbbell Nebula

 

Is this what will become of our Sun? Quite possibly. The first hint of our Sun's future was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, one of the brightest planetary nebulas on the sky and visible with binoculars toward the constellation of the Fox (Vulpecula). It takes light about 1000 years to reach us from M27, featured here in colors emitted by sulfur (red), hydrogen (green) and oxygen (blue). We now know that in about 6 billion years, our Sun will shed its outer gases into a planetary nebula like M27, while its remaining center will become an X-ray hot white dwarf star. Understanding the physics and significance of M27 was well beyond 18th century science, though. Even today, many things remain mysterious about planetary nebulas, including how their intricate shapes are created.

NASA and United lead industry tributes to President Jimmy Carter following death

December 30, 2024, 11:54

 

NASA and United Airlines have lead tributes from the aerospace industry after it was announced that former US President Jimmy Carter had died at the age of 100.

NASA Administrator Bill Nelson said on December 29, 2024, that President Carter was the “pinnacle of a public servant” and a person “who always strove to do what was right”.

 

“President Carter understood an important truth: that we find common ground when we look to the stars.

His words will forever belong to the heavens, and his legacy has forever bettered our country – and our Earth.

The NASA family and I are keeping the Carter family close in our thoughts. May President Carter rest in peace,” said Nelson.

 

United Airlines posted a photo of President Carter stepping off an aircraft chartered by the carrier during the presidential election campaign in 1976 and wrote that it joined the “nation in remembering the life and service of Jimmy Carter”.

Jimmy Carter, the 39th President of the United States, died on December 29, 2024, at his home in Plains, Georgia.

 

In a statement from the White House, President Joe Biden described Jimmy Carter as a “man of character, courage, and compassion, whose lifetime of service defined him as one of the most influential statesmen in our history”.

“He embodied the very best of America: A humble servant of God and the people. A heroic champion of global peace and human rights, and an honorable leader whose moral clarity and hopeful vision lifted our Nation and changed our world,” said President Biden.

 

Delta Air Lines recalled how President Carter would shake hands with each person on the plane when he flew with the carrier.

“Today we celebrate his life – a great friend, family man, Nobel Peace Prize winner and leader who showed us all how to properly treat those around us. Rest in peace, Mr. President. Your legacy lives on,” Delta wrote in a statement.

 

NASA’s Voyager 1, the most distant human-made object from Earth, carries a message from President Carter addressing any other potential life forms in space.

President Carter’s message says: “If one such civilization intercepts Voyager and can understand these recorded contents, here is our message:

This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts, and our feelings.

 

We are attempting to survive our time so we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic civilizations.

This record represents our hope and our determination, and our good will in a vast and awesome universe.”

 

A National Day of Mourning to remember President Carter will be held in the US on January 9, 2024.

Priceless moon rock gifted by Nasa destroyed in observatory fire

December 29, 2024

 

Irish officials were left red-faced after it emerged a priceless piece of moon rock donated by the US and Nasa had lain in a government basement for more than three years before it was later destroyed in an accidental fire at the Dunsink Observatory.

Confidential government documents revealed the plight of the moon rock was highlighted to embarrassed Irish officials only when Washington offered to donate a second piece of lunar rock to Ireland in 1973 following another successful Apollo mission – and government officials were urgently trying to clarify what had happened to the first piece of moon rock.

 

In documents dating from April 27, 1984, it emerged the first piece of moon rock was given by US ambassador J G Moore to president Éamon de Valera.

This gift from the Apollo II mission was made on April 10, 1970.

 

“This piece was given on September 4, 1973, on the advice of the Department of Education, to the Dublin Institute for Advanced Studies for display at the Dunsink Observatory,” a memo noted.

“This piece of moon rock had lain in the basement of this department for three-and-a-half years due to indecision as to where it might best be displayed.

“It was decided to give the moon rock to Dunsink when it became known that a second gift was to be made by the US government and it was thought that some embarrassment would be caused if the first piece was not already on display.”

 

Unfortunately, civil servants noted that the gift to Dunsink had unintended consequences.

“The first piece was destroyed during a fire at Dunsink on October 3, 1977.”

The US gifted Ireland the second piece of moon rock in 1973.

A special plaque including the Tricolour accompanied the gift of the Apollo Mission moon rock.

 

“As the moon rock was given direct to the president, it was put on display in the drawing room of Áras an Uachtaráin,” one document noted.

Later, it was loaned to Aer Lingus at the request of chief executive David Kennedy so it could be featured in the Aer Lingus Young Scientist Exhibition of 1976.

A further memo noted that a permanent display at Áras an Uachtaráin was felt to be inappropriate given that the president’s residence was open only to invited guests – and that the US intention was clearly for the item to be available for public viewing.

 

“The most appropriate museum collection in which it might be exhibited would be the geological or mineralogical collection – [but] the [National] Museum has no space to mount its geological exhibition and therefore the moon rock would have to be put in storage, which would not satisfy the requirements.”

Given the lack of suitable alternatives, it was suggested that it be temporarily given to Aer Rianta where it could be displayed in its main airport exhibition space.

 

“Aer Rianta agreed to accept the plaque for their exhibition and the Office of Public Works (OPW) transferred the plaque to them on October 28, 1975,” another memo noted.

Eight years later, a document noted that the Aer Rianta display had ended and the semi-state body was no longer keen to have the moon rock in its possession.

 

A new Geological Survey Office exhibition space was almost ready and the Department of the Taoiseach noted that this would represent the best future home and display for the moon rock.

It was agreed that, if necessary, it could be loaned back to the National Museum if it was a suitable inclusion in future displays.

Departing Air Force Secretary Will Leave Space Weaponry as a Legacy

Dec. 29, 2024

 

Weapons in space. Fighter jets powered by artificial intelligence.

As the Biden administration comes to a close, one of its legacies will be kicking off the transformation of the nearly 80-year-old U.S. Air Force under the orchestration of its secretary, Frank Kendall.

When he leaves office in January — after more than five decades at the Defense Department and as a military contractor, including nearly four years as Air Force secretary — Mr. Kendall, 75, will have set the stage for a transition that is not only changing how the Air Force is organized but how global wars will be fought.

 

One of the biggest elements of this shift is the move by the United States to prepare for potential space conflict with Russia, China or some other nation.

In a way, space has been a military zone since the Germans first reached it in 1944 with their V2 rockets that left the earth’s atmosphere before they rained down on London, causing hundreds of deaths.

Now, at Mr. Kendall’s direction, the United States is preparing to take that concept to a new level by deploying space-based weapons that can disable or disrupt the growing fleet of Chinese or Russian military satellites.

 

To Mr. Kendall, there is no other choice for the Air Force.

“If there were one thing I could accomplish as secretary, it would be to give the enterprise — the institution — a sense of urgency about responding to the threat and being more prepared,” he said during an hourlong interview at the Pentagon this month with The New York Times.

“Conflict can happen. It’s not inevitable. It may not even be likely. But it can happen at any time. And we need to be ready.”

 

Perhaps of equal significance is the Air Force’s shift under Mr. Kendall to rapidly acquire a new type of fighter jet: a missile-carrying robot that in some cases could make kill decisions without human approval of each individual strike.

In short, artificial-intelligence-enhanced fighter jets and space-based warfare are not just ideas in some science fiction movie.

Before the end of this decade, both are slated to be an operational part of the Air Force because of choices Mr. Kendall made or helped accelerate.

 

The Pentagon is the largest bureaucracy in the world. But Mr. Kendall has shown, more than most of its senior officials, that it too can be forced to innovate.

“It is big,” said Richard Hallion, a military historian and retired senior Pentagon adviser, describing the change underway at the Air Force.

“We have seen the maturation of a diffuse group of technologies that, taken together, have forced a transformation of the American military structure.”

 

Mr. Kendall is an unusual figure to be the top civilian executive at the Air Force, a job he was appointed to by President Biden in 2021, overseeing a $215 billion budget and 700,000 employees.

He grew up on an apple farm in the Berkshire Hills of western Massachusetts, joining the Army while still a teenager.

He later graduated from West Point, followed by the California Institute of Technology, where he received a degree in aeronautical engineering.

 

Before he ended his education, he also earned a Master of Business Administration from Long Island University and a law degree from Georgetown University.

In between jobs at the Pentagon, he served as a human rights lawyer, defending the trial rights of terrorism suspects held at the naval base at Guantánamo Bay in Cuba.

 

Mr. Kendall, who has a folksy demeanor more like a college professor than a top military leader, comes at the job in a way that recalls his graduate training as an engineer.

He gets fixated on both the mechanics and the design process of the military systems his teams are building at a cost of billions of dollars.

Mr. Kendall and Gen. David Allvin, the department’s top uniformed officer, have called this effort “optimizing the Air Force for great power competition.”

 

One of Mr. Kendall’s earliest Army assignments was in the 1970s, when he was stationed in Germany and commanded a team that operated a Hawk missile system designed to defend Europe against potential Russian attack.

The Hawk missile had an onboard digital data processor and radar system that allowed it to evaluate the speed and direction of an approaching enemy missile, and to adjust its course so it could strike and destroy the threat.

It was an early hint of the automation revolution that would eventually lead to the precision military strikes of the Persian Gulf war of 1991 and the remotely piloted drones used widely during the wars in Afghanistan and Iraq — as well as civilian deaths from poorly planned drone strikes there.

Mr. Kendall has taken these innovations — built out during earlier waves of change at the Air Force — and amped up the focus on autonomy even more through a program called Collaborative Combat Aircraft.

These new missile-carrying robot drones will rely on A.I.-enhanced software that not only allows them to fly on their own but to independently make certain vital mission decisions, such as what route to fly or how best to identify and attack enemy targets.

The plan is to have three or four of these robot drones fly as part of a team run by a human-piloted fighter jet, allowing the less expensive drone to take greater risks, such as flying ahead to attack enemy missile defense systems before Navy ships or piloted aircraft join the assault.

 

Mr. Kendall, in an earlier interview with The Times, said this kind of device would require society to more broadly accept that individual kill decisions will increasingly be made by robots.

“In a major conflict, you’d have to deal with a lot of targets in a very compressed time frame,” Mr. Kendall said, meaning that human pilots will supervise the A.I.-powered drones but they cannot be expected to authorize each use of lethal force.

“Individual decisions versus not doing individual decisions is the difference between winning and losing,” Mr. Kendall added. “You’re not going to lose.”

 

These new collaborative combat aircraft — which will cost as much as about $25 million each, compared to the approximately $80 million price for a manned F-35 fighter jet — are being built for the Air Force by two sets of vendors.

One group is assembling the first of these new jets while a second is creating the software that allows them to fly autonomously and make key mission decisions on their own.

This is also a major departure for the Air Force, which usually relies on a single prime contractor to do both, and a sign of just how important the software is — the brain that will effectively fly these robotic fighter jets.

 

Chris Brose, a former Senate Armed Services Committee staff director and now an executive at Anduril, the military contractor building one of the aircraft, said that without Mr. Kendall, production on this new aircraft would not be underway.

“He has proven that real change is possible, at scale,” Mr. Brose said. “There are a handful of other people who played key roles. But if you removed him, this never would have happened.”

 

The open question, added Mac Thornberry, the Republican former chairman of the House Armed Services Committee, is if the pace of change is fast enough.

“There’s a lot of respect for the way he sees the threat, the direction he’s trying to go,” said Mr. Thornberry, who is now a member of the Pentagon’s Defense Innovation Board.

“But some would say that the system is never going to get there in a time frame that matters.”

 

Still, Mr. Kendall has been anything but shy when it comes to demanding change at the Air Force, including operations at the Space Force, the five-year-old agency that he also oversees, Mr. Thornberry and Mr. Brose agreed.

Space, Mr. Kendall said in the interview this month, is no longer just a vast empty region used to deploy satellites that spy on what is happening on earth, or perform other key tasks such as missile tracking, geolocation and communications.

Space is now a fighting zone, Mr. Kendall acknowledged, like the oceans of the earth or battlefields on the ground.

 

The United States, Russia and China each tested sending missiles into space to destroy satellites starting decades ago, although the United States has since disavowed this kind of weapon because of the destructive debris fields it creates in orbit.

So during his tenure, the Air Force started to build out a suite of what Mr. Kendall called “low-debris-causing weapons” that will be able to disrupt or disable Chinese or other enemy satellites, the first of which is expected to be operational by 2026.

 

Mr. Kendall and Gen. Chance Saltzman, the chief of Space Operations, would not specify how these American systems will work.

But other former Pentagon officials have said they likely will include electronic jamming, cyberattacks, lasers, high-powered microwave systems or even U.S. satellites that can grab or move enemy satellites.

 

The Space Force, over the last three years, has also been rapidly building out its own new network of low-earth-orbit satellites to make the military gear in space much harder to disable, as there will be hundreds of cheaper, smaller satellites, instead of a few very vulnerable targets.

Mr. Kendall said when he first came into office, there was an understandable aversion to weaponizing space, but that now the debate about “the sanctity or purity of space” is effectively over.

Space is a vacuum that surrounds Earth, Mr. Kendall said. It’s a place that can be used for military advantage and it is being used for that.

Sun unleashes massive X1.1 solar flare to close out 2024

December 29, 2024

 

The sun is not quite done with 2024.

 

Early Sunday (Dec. 29), the sun fired off a class X1.1 solar flare, one of the most powerful types of solar explosions possible, in what may be its last major flare of 2024.

The solar flare erupted from the northwest region of the Earth-facing side of the sun at 2:18 a.m. EST (0718 GMT) and spawned a strong radio blackout on parts of Earth, NOAA's Space Weather Prediction Center (SWPC) wrote in an update Sunday.

 

"Analysis is currently underway to determine if there was an associated coronal mass ejection, and any potential impacts," SWPC officials wrote in the update.

Coronal mass ejections, or CMEs, are colossal eruptions of solar material that, when aimed at Earth, can amplify northern lights displays and interfere with satellites and power infrastructure on Earth.

 

WPC officials are tracking the impacts of the solar flare to determine if a CME event was associated with it.

If so, it's possible that the flare could supercharge auroras on Earth in a sort of solar fireworks display in time for New Year celebrations.

 

But while the X1.1 solar flare was one of the most powerful type of flares possible, it wasn't the biggest solar flare of 2024.

That title goes to an X9 solar flare on Oct. 3. It was the third largest solar flare since 2011 and the fifth largest since 2005.

 

SWPC officials watched the X1.1. flare erupt with an instrument on its GOES-16 weather satellite.

GOES-16 is part of a fleet of NOAA and NASA spacecraft that monitor the sun continuously for solar flares and other space weather events.
